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 three 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.
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 the Cloud edition 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 the Cloud edition, and goals and reports don't use your article quota.
- ✓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 the Cloud edition. One round of copy uses 1 article of your quota (four images count as 1 article).
- ✓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 Cloud runs on Gemini too. The difference is before and after the writing.

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.
Pricing
Every plan includes AI usage fees. No API key to get, nothing to pay any AI vendor directly.
All you count is the number of articles. Use up your allowance and there's no extra bill, generation simply pauses until next month. Monthly plans are half price for the first month; annual plans get 2 months free plus another 10% off the first year. Start with 3 free trial articles (no credit card needed).
If you write every day, the monthly plans below are the better deal at ¥198 to 327 per article. Single articles and packs also top you up after a monthly allowance runs out. (Sites on the trial can keep going too: just enter the key you receive on the Settings screen.)
Cloud 30
First month ¥4,900 (half price)
- 30 articles a month
- 1 site
- AI usage fees included, every feature

Enter your company name (optional), your name, and your email address on the sign-up form, and we'll email you a 6-digit verification code. Enter the code on the page and you'll immediately get your trial key (3 articles for 30 days from activation) and the installer download. Install the installer on WordPress and enter your key, and the cloud edition installs itself automatically. No API key setup and no credit card needed.

* The verification code is sent only to the email address you entered, and the key is issued only to whoever enters that code (this is to prevent misuse; we don't ask for a phone number). Please make sure you can receive mail from @sorabun.com.
* Add the official LINE account and the greeting message will include a gift code. Enter it on My Page to get 3 more articles (6 total).
Even after you use up your trial allowance, every article, setting, and piece of history you've built stays exactly as it is. To keep going, buy a plan or a single article or pack, then enter the key you receive in the license section on the Settings screen. There is no need to reinstall the ZIP.

Your remaining balance always shows in the dashboard, such as "Remaining: 12 / 30 articles." Once you use up your allowance, new article generation gets queued instead of failing, and picks back up on the 1st of next month, or with a single article (¥500) or a 10-article pack (¥3,980). Monthly allowances reset every month; there's no rollover. Single articles and packs never expire and are used after the monthly allowance runs out. Features that just display, such as podcast distribution, short links, and selling paid articles, never stop even at zero.
The only difference from the Pro edition is the key that calls the AI. The body text and search fact-checking are fixed to Gemini and search runs on Serper, so Claude, Grok, and DeepSeek aren't selectable. Images (Gemini / OpenAI) and audio (Fish Audio / OpenAI) still are. If you'd rather run it on your own key at the lowest possible cost, or keep your manuscripts inside your own API contract, choose the Bring Your Own Key Pro edition (from $19/mo) instead.
Before you buy, please review our Terms of Service, Legal Disclosure, and Privacy Policy (published in Japanese).

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."
"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 really not need an API key?
That's right, you don't. The AI for body text, images, audio, and search all gets called by Sorabun's own servers on your behalf. Each vendor's key lives only on Sorabun's servers and never reaches your site. There's no Google or OpenAI account to create, no credit card to register, and no key to copy and paste.
Does Sorabun store my manuscripts on its servers?
No. Your content only passes through our servers at the moment of generation; what we keep is the count, type, data size, and timestamp of each request. We send everything to AI vendors on a paid tier whose terms exclude it from training. If you need to keep manuscripts inside your own API contract entirely, such as for client work, choose the Bring Your Own Key Pro edition instead.
What happens after my 3 trial articles?
Once you use up your trial allowance, new article generation gets queued instead of failing. Every article, setting, and piece of history you've built stays exactly as it is. To keep going, buy a single article, the 10-article pack, or a plan from My Page (log in with the email address you applied with). Single articles and packs are simply added to your current key, so there's nothing else you need to redo. There is no need to reinstall the ZIP, either. You can also switch to the Pro edition (bring your own key) at any time.
Can I roll unused articles over to next month?
Monthly allowances don't roll over; they reset on the 1st of every month. If you're running short, you can add a single article (¥500) or a 10-article pack (¥3,980). Those are one-time purchases that never expire, and they're used after the monthly allowance runs out.
Can I use it on more than one site?
Yes. Your allowance is tied to one key, and every site that key is registered on shares it. Cloud 80 lets you register that key on up to 3 sites, and Cloud 200 on up to 10, and you can draw on the combined article count from any of them.
I'm already using Sorabun Pro. Can I switch to Cloud?
Yes. Just overwrite your current Sorabun install with the Cloud edition's ZIP file. Your articles, settings, and history all stay exactly as they are. You can switch back from Cloud to Pro the same way, too.
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?
No. The Cloud edition includes the cost of search data (Serper). Connect the free Google Site Kit plugin and you can also pull in real Search Console numbers (impressions, clicks, and average position) at no extra cost.
Can I use an AI model other than Gemini?
On the Cloud edition, the body text and search fact-checking are fixed to Gemini (Sorabun's servers choose the model, so you never have to update a setting when prices change or a new generation ships). You can still choose Gemini or OpenAI for images, and Fish Audio or OpenAI for audio. If you'd rather write with ChatGPT, Claude, Grok, or DeepSeek, choose the Bring Your Own Key Pro edition instead.
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.
