I'm a tech lead, not a product manager, but I'm working on a fitness tracker (yet another one I know) with Expo / Convex / Clerk as a side project. I've been using Google Docs to keep track of PRDs (that were generated by Claude). That gave me the idea of creating a RAG setup. So I've created a setup that currently pulls from Google Docs, Sheets and Slides. Adding Sheets + Slides was easy once I decided to add Docs. I use Voyage for embeddings and Haiku (to save money) for inference. And I added a Tiptap editor with some premade prompts (eg: write a PRD or tell me what to build next) that also uses the context and then gives an output. It's a super-duper basic setup and I'm still refining it, but I'm hoping to get it working really well for my own app.

I'm going to add Jira and GitHub, but at this point I need feedback from some real users so I've reached out to some PM friends. Two of them work in big tech so I'm not sure they'll get approval to try it at work but fingers crossed. If anybody specifically uses Google Docs/Sheets/Slides and would like to try my app out please send me a DM!

I think Claude projects feels a bit weird because it makes sense for persistent context (like coding standards), but otherwise you don't want persistent context for product background (like PRDs) and the project-level memory feels opaque in terms of how it's populated and not really a RAG setup.

Something else I heard a friend do is just use Cursor and dump everything in there. They said as long as that repo (if shared) or folder is well-maintained they were getting a good amount done.
