Privacy

• Yans never sends your text to any AI service. It has no AI of its own.
• It stores only what your AI logs: your sentences, the corrections, and practice summaries.
• Your data is private to you. You can delete all of it, and your account, at any time.

Connect

Yans works with any AI app that supports MCP. Add it as an MCP server with this URL (in the Claude desktop app, a custom connector). You sign in with Google the first time you connect.

https://yans.app/mcp

Claude Code:

claude mcp add --scope user --transport http yans https://yans.app/mcp

Then ask your AI to start a practice session, or to fix a draft.

Run it yourself

Prefer to keep everything on your computer? Yans also runs locally with Docker:

docker run -d --name yans -p 127.0.0.1:7377:7377 -v ~/.yans:/data --restart unless-stopped ghcr.io/wavekat/yans:latest
