KUKURI is a service that lets you build "AI rules" — settings that teach an AI your preferred tone and behavior — just by answering a few questions or picking from ready-made parts. You can load the AI rules you create into ChatGPT, Claude, Gemini, Claude Code, Codex, Antigravity, and more.

It's for anyone who wants to use AI in a way that fits them better. No technical knowledge is needed — you can create an AI rule just by answering a few questions.

You can start for free. If you want to use it more, there are paid plans (Starter and Premium). See the Pricing page for details.

You can search by keyword on the Search page. The top page also shows a popularity ranking, so you can pick from there too.

An AI rule is one complete set of settings. A part is a building block of it — you can combine the parts you like to build your own AI rule.

From Create, just answer a few questions — name, personality, tone, and so on — and a draft is ready for you.

Yes. In Edit, you can add parts, reorder them, and adjust how strongly each one applies.

Yes, on paid plans. Upload a Markdown file you have, and it is split into parts that you can check before importing.

Download it as a CLAUDE.md, AGENTS.md, or GEMINI.md file, place it in your project folder, and use it with Claude Code, Codex, Antigravity, or similar tools.

Yes. From the "Use in web AI" button, you can copy it in a format ready to paste into ChatGPT, Gemini, or Claude. A short guide on how to paste it is shown too.

There are limits on the number of AI rules you can save, downloads, and AI consultations. On the free plan, downloads and AI consultations are a lifetime total; on paid plans they are per week. You can check the limits on the Pricing page.

On paid plans, downloads and AI consultations reset every week, counting from your registration date. The next reset date is shown on the Settings page. Free-plan counts do not reset.

You can sign up for a paid plan on the Pricing page. After that, you can change your plan, cancel, or update your payment method from “Manage plan” on the Settings page.

If you cancel and return to the free plan, your saved AI rules are not deleted and you can still view them. After returning to the free plan, you can use downloads and AI consultations up to the free-plan limits (counts start again from the time you returned). Once you use up either of them, downloads, AI consultations and “Use in web AI” stop, and you can only search and read official AI rules. You cannot create new AI rules while your saved count is at or above the free plan’s limit; delete unneeded rules until the count is below the limit to create again. Uploading your own files and AI compatibility checks are available only on paid plans.

You can log in with an email and password, a Google account, or a GitHub account.

You can reset it from "Forgot password" on the login screen. After resetting, you'll need to log in again.

Please check your spam folder. If it still doesn't arrive, make sure the email address you entered is correct and try again.

Yes. We support 8 languages: Japanese, English, Chinese, Spanish, German, Portuguese, French, and Korean. Before logging in, use the language menu at the top of the screen; after logging in, use the Settings page.

You can delete it from the Settings page. Once you delete your account, the workspace contents you saved can no longer be used. If you are on a paid plan, deleting your account cancels the plan right away and the remaining period is not refunded. To use it until the end of the period, cancel the plan first.
