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.

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.
There's more
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.
- ✓Known vulnerabilitiesMatched against 40,000+ records: none found
- !Update nowContact Form 7 5.8 → 5.8.1 (XSS fix)
- ✓WordPress core tamperingAll files match the official ones
- ✓Plugins and suspicious files1,248 files checked: nothing found
- ✓Firewall37 attacks blocked today
- ✓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.
Vulnerability data: Wordfence Intelligence (updated daily)
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.
- ✓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.
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).
- ✓Track record and pricingOnly what you entered, no numbers made up by AI
- !"Guaranteed results"Advertising claims: absolute statement
- !"98% satisfaction"Not in your input, check that it is real
- ✓HeadlineChosen from three different angles
A proven structure, in four types
Choose service, store, seminar or free consultation. The structure and the final button change with the type, and you pick the headline from three angles.
No made-up facts, with a claims check
Track record, customer voices and prices come only from what you enter. Risky advertising and health claims, and numbers not in your input, get flagged before you publish.
Standard blocks, all the way to click rate
A draft Page built from standard blocks you can edit in any theme. noindex, an inquiry form at the end, and views and click-through rate for every LP.
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.

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.

Get a key from Google AI Studio without a credit card. Stay inside the free tier and there's no API cost at all.
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).
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.

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.

See PricingWhat 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.
"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."
"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."
"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."
"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."
These are individual opinions from early testers of the Japanese version of Sorabun. They don't guarantee any particular result.
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.
