Late to the game here, but I'm working on Basic Memory (https://memory.basicmachines.co/docs/introduction), a knowledge management system for the Model Context Protocol (MCP).

What makes it different:

* Claude (and other MCP AIs) can both read from and write to your local markdown files

* Creates a connected network of notes that Claude can navigate between

* All data stays as markdown files on your computer

* When you chat with Claude, it automatically builds structure with simple patterns

* You can start a new chat and just say "Let's continue discussing X" without uploading files or copy/pasting

* Files are available locally, so you can edit them in and editor, like Obsidian, VS Code, etc.

I built this because I was tired of repeating myself to AI assistants and wanted my conversations to accumulate into something useful over time. It's basically a way to give Claude persistent memory while keeping your data local and be easily readable and editable my humans.

Some people are using it to maintain project context across sessions, document systems, and build topic maps without having to manually organize everything.
