I have a "second brain" filesystem as markdown files that I have been maintaining for months that started out in Claude Code as the interface + file read/write layer... This system just stores a collection of personal todo items, long/short term goals, journal entries and integrates into my calendar and gmail.
When Claude Chat released their voice feature, I created a Claude Project with a snapshot of the files within my second brain. I was pleasantly surprised with how well this feature worked. It made accessing my second brain on the go so much easier and I was using my second brain much more.
The biggest point of friction with this system however is updating the files. These files go stale so quickly. I will have a productive claude chat session and I would need to ask for a convo summary on convo wrap up, then paste that summary into Claude Code so it can edit my files. THEN I'd paste over those files into my claude project.
Really annoying but still works. I just need to sit down every week or so and update my files. Not the end of the world but I feel like this could be fixed SO easily if Anthropic would allow claude chat to edit project files the same way Claude Code does.
Not sure if anyone has a similar setup and / or has come up with a clever workaround to this. I was thinking about creating an MCP server that would host my files somewhere and give claude chat read/write access. Feels like overkill though.
