Say it messy, we'll file it neatly.
Dump half-formed 2am thoughts, to-dos, and rambles into a simple inbox, and an agentic Gemini pipeline reads through the mess, decides how it relates to your existing notes, and writes a clean, titled, tagged page straight into your Notion workspace.
Scope & impact
- Agentic pipeline built on a custom MCP tool server plus Notion's own hosted MCP server, orchestrated by Gemini via the Vercel AI SDK
- Strict Zod-wrapped tool schemas force exact Notion property shapes and a required clear-processed step, so the agent can't silently write malformed or duplicate pages
- Two-legged OAuth setup — Better Auth for identity plus a full RFC 8414/9470 MCP OAuth (PKCE) flow — authorizes the app against the user's own Notion workspace
