Best for search research for an AI assistant
Kafkai gives an AI assistant search data: keywords, backlinks and competitors, paid by credits instead of a monthly plan. It has no writing tool of its own, it runs through MCP with about 30 minutes of setup, and credits expire after 90 days.
Who Kafkai is for
- Fits if you already work in Claude, ChatGPT or Cursor and want search data inside it
- Works for one-off research projects, since you pay as you go
Who Kafkai is not for
- Skip it if you want an article writer, because there is no writing tool of its own
- Not for you if you don't use an AI assistant over MCP
- Tight if you want rank tracking, since research runs only when asked
- Watch out: prices are in yen with Japanese consumption tax, and credits expire after 90 days
Why Kafkai gets a 1.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyPay-as-you-go credits in yen: ¥1,000 buys 1,000 credits, enough for one project with one competitor. It isn't a monthly plan, so it can't be set against the category cleanly.
- CFree plan and trial1,000 free credits on signup with no card, valid for 90 days.
- DFeaturesKeyword, competitor and backlink research, with Search Console data and WordPress drafts. It needs an AI assistant to be useful and has no writing tool.
- DEase of useAbout 30 minutes of one-time MCP setup through an AI assistant.
- BPlatforms and integrationsWeb, with Claude, ChatGPT, Cursor, Claude Code and WordPress.

Keep Kafkai, or make your own?
Keep it
To replace Kafkai you would be making search volumes for millions of keywords, gathered and kept up to date. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 119 of the 136 other writing tools grade higher.
What you could not
- Search volumes for millions of keywords, gathered and kept up to date.
- An index of the links between billions of web pages.
- Daily checks of where your pages rank in search results.
- It plugs into other products, Claude, ChatGPT and Cursor among them.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Kafkai’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Kafkai?
Kafkai is now a plugin (MCP) that connects an AI assistant such as Claude or ChatGPT to search data, so questions about what a site ranks for, who links to it and who competes with it are answered from real numbers. It no longer sells the AI article writing it was known for. It is prepaid: credits are bought in packs and spent per question, with no monthly plan.
Worth knowing
- Prices are in Japanese yen and include Japanese consumption tax; the checkout works out tax from the billing address.
- Credits expire 90 days after they are granted or bought.
- It does not track rankings on a schedule; research runs only when asked.
- It is used through an AI assistant over MCP, with a roughly 30-minute one-time setup, and has no writing tool of its own.
Key features
- Keywords and content gaps
- Lists the keywords a site ranks for with position and monthly search volume, and the keywords competitors rank for that it does not.
- Competitor finding
- Returns the sites that rank for the same searches and how far their keywords overlap with yours.
- Backlinks
- Shows who links to a site, new and lost links by date, and the sites that link to competitors but not to you.
- Search Console for your own site
- After you prove the domain with a DNS record, pages and searches losing clicks can be read through the same AI.
- Amazon and Google Shopping checks
- Shows where a product appears in Amazon and Google Shopping results for a keyword, in the supported countries, at 5 credits per keyword.
- WordPress drafts
- Your AI writes the article and Kafkai sends it to a WordPress site as a draft; Kafkai itself does not write or store articles.
