Show HN: I built a pocket dimension for notes and context in LLM-space

https://www.kept.fyi/
1•reb•4mo ago
I've been building a bunch of little apps with AI tools for the last few months and find myself constantly passing research, plans, and working frameworks between tools and projects. At this point it's become one of the more time-consuming parts of my creative process and gets in the way of the parts I enjoy, so I built a tool to make it easier.

It's up where anyone can use it and it's free — if people find it useful and want more than the basic level of daily usage I can afford to cover myself, I'll think about offering a paid tier.

Here's how it works:

1. You sign up and get your own notes space (using github for ID, not code access) 2. You connect your tools (this is one-click for Cursor and VS Code, copy-paste for Claude Code, and a couple of clicks for Claude) 3. Use your tools as usual, letting them know when and what to store in your space 4. Any of your connected tools can then look for relevant notes while they work (or you can tell them to reference specific notes anytime)

It's pretty flexible, so I'm still exploring what it's best for. Right now I'm using it to store and retrieve .rules files and commands I re-use regularly, pass project plans between the Claude (where I brainstorm throughout the day) and Cursor on my laptop (where I write and generate code), and have llms working in separate codebases store shared knowledge they both need.

The stack for the service includes... - Supabase for auth + storage - Next.js + shadcn for the web app - A MCP server to handle LLM<->DB communication

Happy to answer any questions folks have and would love to hear what anyone who gives it a try thinks (good and bad)
