I've wanted something like this for a long time and finally built it over the weekend after seeing a tweeet about LLM memory. Perchpad is a collaborative real-time Markdown editor where your workspace is just a folder of flat .md and .csv files, version-controlled with Git.
Key things:
Git-native storage, your workspace is plain files. git clone them, download as zip, or just edit locally. No proprietary format lock-in.
Deep LLM support. hook it up to Claude as persistent memory/context. The LLM integration is fairly capable for drafting and editing within docs.
Web based real-time multiplayer – full collaborative editing, multiple cursors, the usual.
Text-to-speech longform read-aloud with decent voice options.
The idea is that your notes and docs should be portable plain text first, collaborative second, and AI-augmented third — not the other way around. Would really appreciate any feedback. Happy to answer questions here.
How does the git part work if you are always fighting github authentication. It's git only, not github?
