We also have ADR, AGENTS.md, LLMs, and a few other free tools.

Just updated my context builder https://reddit.com/link/1utq6y0/video/jy8bpbotxmch1/player You can now upload your whole project folder and get one clean, optimized markdown file that you can paste straight into Claude or Codex. All file uploads are 100% client-side. Let me know if you find this useful or not, would love some feedback! https://markdone.dev/ai-context-builder/ submitted by /u/Jealous_Buy_8829 to r/SideProject [link] [comments]
