Letterly gemini-cli

Letterly + Gemini CLI

Bring your voice notes into Google’s Gemini CLI. Search notes, pull context, and capture ideas without leaving the terminal.

Why use it

Gemini CLI gives you access to Google’s AI models from your terminal. With Letterly connected, you can pull your voice notes into any Gemini session — architecture decisions, meeting notes, brainstorms, anything you recorded.

Setup

Add Letterly as an MCP server in your Gemini CLI settings file (~/.gemini/settings.json):

{
  "mcpServers": {
    "letterly": {
      "url": "https://mcp.letterly.app/mcp"
    }
  }
}

Restart Gemini CLI after saving. The OAuth sign-in will open in your browser on first use.

Verify the connection

Start a new Gemini session and ask it to list your recent notes. If it returns results, you’re connected.

Tips

  • Project-level config. You can also put settings in .gemini/settings.json inside your project root for per-project configuration.
  • Capture ADRs. Record architecture decisions on the go, then ask Gemini to find and format them when you need to document.
  • Context before coding. Ask Gemini to pull up relevant notes before starting a task so it has the full picture.
