WordPress AI Content Engine

AI Content That Doesn't Stop at Publish.

Sorabun is the WordPress AI Content Engine that plans, writes, and publishes your articles, built to get cited by Google AI Overviews, ChatGPT, and Perplexity, not just ranked on the blue links. Then it tracks their real Google rankings every day and rewrites the ones that fall behind. One plugin, one loop, running inside the WordPress you already use.

Gemini API has a free tier, so you can try it at $0

FEATURES

Every Step of Content, in One Plugin

From keyword research to fixing the articles that stopped ranking, Sorabun does the work an SEO team does every day, running inside WordPress itself.

🗓

An AI editor builds your calendar⁠NEW

Sorabun decides which article, in what order, and when to publish it, and shows its reasoning. Approve the calendar once and each article gets built automatically on its scheduled day.

🔁

AI Director runs the fixes itself⁠NEW

Working from measured rankings and read-through data, it picks the single biggest problem holding a page back, fixes it, predicts the result 28 days out, then checks its own prediction against reality.

✅

A site audit sets the foundation⁠NEW

Enter your site name, theme, and competitors and Sorabun runs an SEO audit, proposes your first five articles, and carries what it learns into every article after.

⭐

Titles built to get clicked⁠NEW

Sorabun assembles each title from 14 proven headline patterns. Three alternates sit on the review screen. Swap in one click.

💰

Sell articles for money⁠NEW

Gate the rest of an article behind a one-time purchase or a monthly membership. Sell articles individually, or bundle them into a magazine. Revenue lands directly in your own Stripe account. You can also gate content behind a LINE follow instead of a payment, if you'd rather trade access for subscribers.

🎨

Featured images & diagrams, automatically

Sorabun generates a title-branded featured image plus flow charts and comparison diagrams, then checks each one for AI-art glitches (extra fingers, garbled text) and regenerates anything that fails.

📊

Rank tracking & SEO insights⁠NEW

Tracked keywords get checked daily, and whether your site was cited in Google's AI Overviews gets recorded at the same time. Connect Site Kit and Sorabun still surfaces "hidden-gem" queries and slipping articles straight from your real Search Console data.

🎙

Turn an article into a podcast episode⁠NEW

Turn any article into audio in one click from the posts list, and distribute it straight to Spotify and Apple Podcasts. You can also have your own script read back exactly as written, word for word.

🔒

Screen out mass-mailed sales outreach⁠NEW

Every inquiry that reaches the built-in form gets checked for whether it actually engages with your site, the tell that separates a real message from mass-mailed sales outreach. A wrong call still keeps the message on file instead of discarding it. No plugin required to add the form.

💎

Make your credentials count⁠NEW

Built for fields like medicine, law, and tax, where the writer's standing is itself part of an article's weight. Register yours and the AI stops retreating into generalities, and the author in your structured data comes with credentials attached.

🛡

Watch the ways in, every day⁠NEW

Reads the changelogs of plugins waiting for updates and flags only the updates that contain security fixes as "Update now". Checks WordPress core for tampering against the official file list daily, and stops login brute force.

🗺

Map your internal links⁠NEW

Records which article links to which, and with what words, every time you save. See orphan articles nothing links to and whether links gather on your pillar articles at a glance.

SECURITY

Security, handled in the same plugin.

Most WordPress takeovers start with a plugin that was fixed but never updated. Sorabun watches your plugins every day, flags only what's urgent, and closes the ways in. Included in Pro at no extra cost.

  • ✓Two-factor and passkeysAll 3 administrators set up
🔍

Known vulnerabilities, checked daily⁠NEW

Installed plugins, themes and core are matched every day against a database of 40,000+ vulnerabilities. Dangerous ones with no fix yet get a "deactivate" alert.

⚡

Auto-apply security fixes only⁠NEW

WordPress auto-updates are all-or-nothing. Sorabun can apply only the urgent updates automatically, without changing anything else.

🔐

Two-factor authentication⁠NEW

Log in with a 6-digit code from an authenticator app as well as your password. A leaked password alone won't get anyone in. Scan a QR code to set up; can be required for admins.

🧪

Tampering and suspicious file scan⁠NEW

Plugins are compared against their official files to find modifications and planted PHP. AI explains anything it finds in plain words.

📜

Activity log and instant takeover alerts⁠NEW

90 days of who did what, and when. You're notified the moment a new admin appears or the site URL is changed.

🛡

Close the ways in⁠NEW

Lock out login brute force, and stop username leaks, XML-RPC and PHP in the uploads folder. Passwords leaked from other sites aren't allowed either.

🧱

Firewall⁠NEW

Blocks obvious attacks at the door, such as SQL injection and probes for config files. Robots that fire off requests for missing pages hunting for weaknesses are locked out too (search engines excluded).

🔑

Log in with passkeys⁠NEW

Log in with a fingerprint, face or PIN, no password. The key stays on your device and won't respond on fake sites, so it resists phishing.

🌏

Country blocking⁠NEW

Let the login screen open only from the countries you choose. Most brute-force attempts from abroad are turned away at the door. Settings that would lock you out aren't saved.

🔒 Only plugin names are sent For matching, the only thing that leaves your site is plugin and theme names. Installed versions and site contents stay put.
🔑 Locked out? One line gets you back If a setting locks you out, one line in wp-config.php turns it off. Monitoring and alerts keep running.
🤝 Works alongside security plugins Entry-point settings are off by default, so they won't overlap with Wordfence or similar. Start with just the monitoring.

NEW FEATURE

See what your articles actually achieved.

Track what your articles led to, not just how many you published. Set goals for monthly search clicks or inquiries, and Sorabun shows every day where you are and whether you'll get there at this pace. It records which article each inquiry and sale came from, and weekly or monthly reports arrive on their own. Included in Pro at no extra cost.

Goal progress (screen preview)As of September 18
  • ✓Monthly search clicks: 3,000Now 1,840, on track
  • !Monthly inquiries: 20Now 6, behind
  • ✓Top 10 keywords: 30 by end of DecemberNow 21, ahead
  • ✓Monthly AI cost within 5,000 yenNow 2,100 yen, expected to stay under the cap
📊

Goals and pace, every day

Set goals by month or by a deadline, and Sorabun projects where you'll land at the end of the period from your progress so far. The AI Director picks actions that recover lagging goals first.

💰

Know which articles paid off

Inquiries are counted by the article they were sent from, and sales by the article that was bought. Search Console data is imported automatically every day, with a 6-month trend.

📅

Weekly and monthly reports, automatically

Goal progress, the change from the previous period, rising and falling articles, and what to do next, emailed automatically. A summary can go to Slack or Chatwork too.

🔗

A link to share with clients

Share a client-facing report with one link, no login needed. AI costs and internal notes stay hidden, and the page is kept out of search engines.

🔍

Audit articles written before Sorabun

Older articles are read too, with review dates and a priority order, each with reasons. Overlapping or thin articles are flagged to consider deleting or merging (nothing is deleted automatically).

📝

Review rewrites before they go live

For published articles, rewrites are saved as a rewrite draft, and you apply them after checking the diff. The URL and publish date stay the same, and the old text stays in revisions.

NEW FEATURE

Landing pages, written by AI too.

Just enter your product or service. The AI writes landing page copy that follows problems → solution → features → how it works → track record → pricing → FAQ → sign-up, and builds it as a draft WordPress Page. It works with any theme, and you edit it right in the block editor. Included in Pro at no extra cost (AI API usage: one round of copy, plus one image if you generate it).

Pre-publish check (screen preview)Right after the copy is written
  • ✓Track record and pricingOnly what you entered, no numbers made up by AI

WHY SORABUN

What's Different From Writing in ChatGPT or Claude Code

Being honest, the writing itself is no longer the hard part. Most AI models are good at it now. Sorabun is built on Gemini, ChatGPT, Claude, Grok, and DeepSeek too. What actually separates it happens before you write, and after you publish.

⚡
It runs entirely in your browser No terminal, no command line, no juggling API calls. Anyone who can log into WordPress can run it the same way you do, including a freelance writer or a non-technical teammate. That's a line CLI coding tools can't cross.
📊
It doesn't stop when the article is done An AI coding agent's job ends the moment it outputs a draft. It never checks where that article ranks, how often it's shown, or how far people read. Sorabun stays wired to what happens after publish, and those numbers decide what gets written next.
🧠
It already knows your site Sorabun writes with your full article history, categories, and past results in view. It avoids repeating a keyword you've covered, adds internal links, and doesn't retry a fix that already failed. You never re-explain your site from scratch.

📖 Being honest about this For writing code, modifying an existing system, or digging into a complex problem through back-and-forth conversation, Claude Code and Codex are the better tool. Use each one for what it's good at. Sorabun's job is running the article pipeline: planning through post-publish improvement, every day, from inside a browser. That isn't where a CLI tool plays to its strengths. And it doesn't stop at that division of labor. From Claude Code, you can call Sorabun directly over MCP. Ask it to "write this article" right in the middle of your coding session, and the same editorial team goes to work.
NEW FEATURE

Ask Claude or Cursor to "write an article." Right from your editor.

A WordPress site with Sorabun installed becomes an MCP server on its own. Just register your site's URL and API key with an AI tool like Claude Code, Claude Desktop, or Cursor. No extra software to install, and no integration code to write.

🔌 No extra software required The MCP endpoint lives inside WordPress itself. No Node.js wrapper, no relay server, no separate monthly service. Register your URL and API key and you're connected right away.
🧩 Engineers and non-engineers run the same editorial team Engineers work from Claude Code, writers work from the WordPress dashboard. Only the entry point differs; the same Sorabun runs underneath. The articles it makes, rank tracking, and AI Director's fixes all land in the same place either way.
🔒 The AI can only do this much Only the eight tools listed above are reachable through MCP. It can't change settings, delete articles, or touch your API key. Publish status can only change at article-generation time, and drafts are the default. You can reissue your key from the dashboard anytime.
🔗 Also works as a REST API The same key lets Zapier, Make, n8n, or your own scripts call article generation too. You could wire up something like: add a row to a spreadsheet, and an article comes out.
OPTIMIZATION

Written to Rank and to Get Cited by AI

Ranking in the list of results isn't enough anymore. Google AI Overviews, ChatGPT, and Perplexity answer the question on the spot, so an article that never gets cited never gets seen at all.
Sorabun reshapes not just the writing but the article's structure itself to get it cited. Then it checks every day whether you actually got cited, recording your site's presence in AI Overview sources alongside each rank check. Pick from five optimization types depending on what you're targeting.

SEOClassic search-engine optimization: heading structure, metadata, and co-occurring terms matched to search intent.
AIOBuilt for Google AI Overviews: a direct, conclusion-first answer plus FAQ structured data.
LLMOStructured to get cited by ChatGPT and similar LLMs: clear factual statements, Q&A pairs, and a TL;DR.
GEOBuilt for generative search engines like Perplexity: statistics, cited sources, and E-E-A-T signals.
HybridA balanced blend of all four, and the safe default if you're not sure.
PRICING

What Sorabun uses
About 10-15 requests per article

As of August 2026, Gemini 2.5 Flash offers a free API tier through Google AI Studio. The daily limit varies by Google Cloud project, and Google no longer publishes a fixed number. Check your own limit under "Active rate limits" in AI Studio (see the official docs). Higher-tier Pro models and image generation may require the paid tier.
The "1,500 requests/day" figure on Google's pricing page is actually the free Search-grounding allowance on the paid tier, not a request cap. On the free tier, Search grounding is capped at 500/day, shared across Gemini 2.5 Flash and Flash-Lite, so don't confuse either number with the normal API request limit.
On the free tier, what you send may be used to improve Google's models. If you're writing about confidential or client work, switch to the pay-as-you-go tier instead, since per-article cost there is still low.

Before you buy, please review our Terms of Service, Legal Disclosure, and Privacy Policy (published in Japanese).

NEW FEATURE

Your Article, Turned Into a Podcast Episode.

Sorabun rewrites an article as a spoken-word script, narrates it with AI voice, and generates the RSS feed a podcast needs. It's ready for Spotify, Apple Podcasts, and Amazon Music, with no extra monthly hosting fee.

Note: narration requires a text-to-speech API key (Fish Audio or OpenAI) of your own. You only pay for what you use, roughly $0.07 to $0.20 per episode (a 5,000-character article, about 10 minutes). The script itself is generated with the same text-generation AI key used for the article. Distribution itself costs nothing.

💸 No extra fee to distribute. You only pay the speech API No podcast hosting subscription to buy (typically $10-30/month elsewhere). The RSS feed and the audio files live on your own WordPress install. The only cost is the pay-as-you-go text-to-speech API (Fish Audio or OpenAI): roughly $0.07 to $0.20 for a 10-minute episode, or about $2 to $6 a month at one episode a day.
🔁 Register once, then forget it Submit your feed URL to each platform one time; every episode after that gets picked up automatically. From the second episode on, you just write the article. Spotify and Apple Podcasts take care of the rest.
✅ Catches Apple's rejection reasons before you apply Cover-art sizing (a 1400-3000px square) and missing owner info are the usual reasons Apple Podcasts bounces a submission. Sorabun checks both automatically before you apply. Fill in what it flags and you clear review.
⚡ Runs fully automatically too Turn on "publish as soon as the audio is ready," register your keywords, and articles plus episodes stack up daily with nobody touching it. Or review and publish each one by hand. Your call.
NEW FEATURE

From an AI That Writes Articles to One That Chases Results.

AI Director reads what happens after publish, decides what to do about it, acts on that decision, and checks the outcome against real numbers. Publishing more articles doesn't move rankings by itself. Knowing why one didn't work is what makes the next one better.

Prediction (locked in before running) 1.43% → in 28 days → 2.10%
Actual, 28 days later 1.88% Improved (fell short of target)
What it learnedThe title changes worked, but some articles still had their old meta description. The next round closes that gap.
🧮 It doesn't let the AI grade its own work Ask an AI "did that work?" and it will almost always say "yes, to some degree," which teaches you nothing. AI Director grades only against measured numbers, then hands the AI a confirmed result and asks it to explain why, not whether.
⚠ One change at a time, always Change three things at once and you'll never know which one worked. AI Director commits to a single bottleneck per round. It looks slower. It compounds faster.
🧠 The longer it runs, the more it knows your site "Top competitors have heavy backlinks, so article quality alone won't close that gap." A missed prediction becomes an input to the next plan. What accumulates isn't generic advice. It's knowledge specific to your site.
🔒 It never publishes without you Articles are always saved as drafts for review before anything goes live (a fully automatic mode is available too). When the data it needs isn't there yet, it stops and tells you what's missing instead of writing something generic.

What Early Testers Said

Feedback from testers who used the Japanese version of Sorabun before its public release, translated into English.
Names are shown as initials at each tester's request.

Writing articles got a lot easier

"Honestly, I assumed this was just another AI writing tool at first. But having everything (keyword selection, the body copy, images, formatting) happen inside WordPress itself turned out to be genuinely useful. I still edit the text a little, but it's a huge step up from starting from a blank page."

A
A.Runs a personal blog
I can focus on polishing instead of drafting

"Research and outlining used to eat most of my time on every article. Sorabun gets me to a review-ready draft in one pass, so I spend my time refining instead of starting from zero. Being able to check rankings and rewrite after publishing, in the same place, has genuinely helped too."

B
B.Runs a company blog
Once it's set up, it's easy to use

"The API key setup tripped me up briefly, but once that was done everything made sense. It's less 'hand everything to the AI' and more 'hand off the tedious parts of making an article.' I'd expect it to matter most if you're running more than one site."

C
C.Web agency
Turning the blog straight into a podcast is genuinely impressive

"I'd wanted to try podcasting for a while, but scripting, recording, and setting up distribution all looked like a lot of work to start. With Sorabun taking an article all the way to audio, getting an actual show running was a lot easier than I expected. Having another channel to publish to feels great."

FAQ

Frequently Asked Questions

Do I need my own API key? What does it cost?

Yes. One API key for a text-generation AI (Gemini, ChatGPT, Claude, Grok, or DeepSeek). Gemini's API has a free tier you can get without a credit card. As of August 2026, Gemini 2.5 Flash offers a free API tier through Google AI Studio. The daily limit varies by Google Cloud project, so check your current rate limits in AI Studio. Sorabun uses roughly 10-15 requests per article.

Past the free tier, or on a higher-end model or image generation, you pay that provider's standard usage rates, typically a few cents to a few dollars per article depending on the model, length, and number of images. On the free tier, what you send may be used to improve the model, so for confidential or client work we'd recommend the pay-as-you-go tier instead.

What does AIO/LLMO optimization actually do?

It reshapes the article's structure into a form AI can cite. Concretely: putting the conclusion right after the heading (conclusion-first), building out question-and-answer pairs, adding a TL;DR at the top, stating figures and sources explicitly, and outputting FAQ structured data. Polishing the prose alone doesn't get an article cited in an AI answer.

You choose from SEO / AIO / LLMO / GEO / Hybrid depending on what you're targeting. AIO targets Google's AI Overviews, LLMO targets ChatGPT and other LLMs, and GEO targets generative search engines like Perplexity. If you're not sure which to pick, leave it on Hybrid, which blends all of them and is the default. It can be set per article. Whether you actually got cited can be checked daily in the "AI Overview" column on the Rank Tracking screen.

Is it safe to publish generated articles as-is?

By default, everything saves as a draft, so a person reviews it before it goes live. You can even review and edit the outline before the article is written. Fully automatic publishing and scheduled posting are both available if you'd rather hand off the whole loop.

Can I use it from Claude Code or Cursor?

Yes. A WordPress site running the Pro or Cloud edition becomes an MCP server on its own. From Claude Code, it's one line with claude mcp add; for Cursor or Windsurf, you just add the URL and API key to a config file. A client that can't attach a header, like Claude Desktop, connects through mcp-remote instead. The "REST API / MCP integration" settings screen shows copy-and-paste setup steps for each one.

All it can do is create articles, rewrite them, check progress, and read articles, eight tools in total. It can't change settings or delete articles, and publish status defaults to draft.

Does it work with any WordPress theme?

Yes. Sorabun works with any theme without breaking your layout. It auto-detects the Cocoon and SWELL theme frameworks and uses their native styling classes for callouts and highlights; on every other theme (including all the major English-language ones), it falls back to universal, theme-agnostic formatting.

Is there an extra cost for rank tracking?

Rank data comes from a SERP API such as Serper.dev, which has a free tier and is inexpensive beyond that. Connect the free Google Site Kit plugin and Sorabun also pulls your real Search Console numbers (impressions, clicks, and average position) at no extra cost.

Can I use an AI model other than Gemini?

Yes. On the Pro plan you can choose ChatGPT, Claude, Grok, or DeepSeek as your writing model (each needs its own API key). Research that depends on Google Search grounding always runs on Gemini for accuracy. You're choosing the model for the writing itself, in a hybrid setup.

Can it create things besides articles?

Yes. On Pro, one click turns a generated article into a social post thread and a YouTube script at the same time. Automatic translation into Japanese, Chinese, Korean, and Spanish is also available, so you can run a multilingual site from a single source article.

Do I need a separate podcast hosting plan?

No. Spotify, Apple Podcasts, Amazon Music, and Audible all work the same way: register your RSS feed URL once, and every episode after that is picked up automatically from then on. Sorabun generates that feed inside your own WordPress install, so there's no hosting subscription (typically $10-30/month elsewhere) and no extra API key to manage. The only ongoing cost is the text-to-speech API you use (Fish Audio or OpenAI TTS), billed by usage.

Does publishing a podcast episode need manual work every time?

No. You register your feed URL with each platform once; every episode after that reaches listeners automatically, usually within a few hours. Turn on "publish as soon as the audio is ready" and the whole path from article to episode runs with nobody touching it. You can also review and publish each episode by hand if you'd rather.

Can it create Pages, not just blog posts?

Yes. Each time you generate an article, you choose Post or Page. That's useful for content you don't want sorted by date, such as an About page, a pricing page, or an FAQ page. Set your usual default in Settings, then override it on the article creation screen whenever one piece needs to be the other type.

Choosing Page means no category gets attached, since WordPress Pages don't have categories. Pages are also excluded from the Rank Tracking and Site Diagnosis totals, which only look at blog posts. In-article CTAs, paid articles, and LINE-exclusive content all still work the same way on a Page.

Can it create landing pages too?

Yes (Pro and Cloud editions). Enter your product or service under "Sorabun > LP Builder", and the AI writes copy that leads to sign-up, built as a draft Page from standard blocks. Track record, customer voices and prices come only from what you enter, and risky advertising claims or numbers not in your input are flagged before you publish.

Can I send results reports to clients?

Yes. Under "Goals & Reports," create weekly or monthly reports and email them automatically. You can also create a client link that works without logging in, which hides AI costs and the internal "What to do next." The link is kept out of search engines and can be stopped at any time. Goals and reports are included in the free edition (Sorabun Lite) too (Search Console data and sending to Slack or Chatwork need Pro or Cloud).

Does it work alongside Yoast SEO or Rank Math?

Yes. Sorabun auto-detects Yoast SEO or Rank Math and writes directly into their meta title and meta description fields. If neither is active, Sorabun outputs its own meta tags instead.

Does it work alongside security or speed plugins?

Yes. Sorabun's Security / Speed screen centers on monitoring: known vulnerability matching, watching for updates with security fixes, tampering and suspicious file scans, and an activity log, which don't conflict with other plugins. Settings that close entry points, such as two-factor authentication and login limits, are off by default, so if you use Wordfence or similar, turn each feature on in only one of the two. WebP delivery is also off by default and never modifies your original images; if you already use another image optimization plugin, leave it off.

Publishing isn't the finish line.

Decide what to write, then come back and fix it once the numbers come in. Try running that whole loop inside your own WordPress.
