So I built dullnote. It's a hosted markdown editor that Claude reads and writes via MCP. You store project notes, decisions, logs. Claude accesses them across sessions.
Version history tracks every change. Diffs show if you made the edit or Claude did.
Stack: React, FastAPI, Supabase, Hetzner VPS.
Free tier available. Signup required because files are private by default and need auth to sync with MCP.
Been using it a month. It's changed how I work, but I'm too close to it now.
Would love feedback: - Is this useful outside my own workflow? - What would stop you from using it?
Be brutal.
