The problem

What you work out with one AI assistant stays with that assistant. Switch from ChatGPT to Claude and you start explaining from scratch.

What I built

  • A Next.js and TypeScript web app, and remote MCP server tools backed by PostgreSQL.
  • Save notes from Claude or ChatGPT into topic-sorted projects, then recall them in either.
  • OAuth with PKCE, refresh-token rotation and scoped permissions, so you choose what each assistant can see.
  • Idempotent saves and structured topic classification, covered by over 480 automated tests.
  • Imports from ChatGPT exports, file uploads, and project backup and restore.

Built with

next.js · typescript · postgresql · mcp · oauth
