A place where what you wrote with another AI becomes an approved version.
Keep ChatGPT, Claude or Codex. Save the drafts you wrote there into a project, and keep the version you approved, the client's confirmation and the rule for next time in Tsuguri.
In a general chat, context and corrections scroll away. Tsuguri keeps the source and the approval record with each project.
How it works
- Create a project, then copy the brief and context to your AI
- Save the text that came back as a draft
- You review and approve it, and share a confirmation link with the client if needed
What you keep
- A record of which AI the draft came from (as you declare it)
- The approved version and the client's confirmation
- Next-time rules and their expiry
No card required. After sign-up, the projects screen opens. Creating a project runs no AI and starts no charge.
Call the Japan desk from your own AI
Connect Tsuguri's Japan desk to an AI that supports MCP (Claude, ChatGPT, Codex and others). For ad copy, social posts, product pages, marketing email, invoices, outsourcing terms or purchases under a subsidy, it returns the AI partner's questions to confirm and the official Japanese sources with their check dates. Your AI applies them to your draft.

- No sign-in, read-only. Your text is never sent: the AI names only the kind of work. No AI model runs on Tsuguri's side.
- It returns questions and sources, not legal, tax or eligibility determinations, and prepares no application documents. Guidance past its review date is left out and flagged.
- In Claude Code:
claude mcp add --transport http tsuguri-japan-desk https://tsuguri.net/api/japan-desk - In other AI tools, add this URL where they accept a remote MCP server (custom connector). Check each service's help for availability and steps.
