Why I built it
Figma Make was in beta and I wanted to test it on something real. Could AI help me build a whole product, not just a screen?
The problem I picked: good prompts are valuable, and they get lost in chats, notes and messy docs.
What it was
A place to write, organize and version AI prompts.

Teams were next on the roadmap.
I built the interface in Figma Make, the backend on Supabase using the Figma Make integration, and ran the work in Linear like a real product. Around it I made a landing page, an early-access social campaign, a release plan, a market analysis and user personas.
Why I stopped
The problem moved. Prompts stopped being something people save: every AI chat is now prompting. Then skills arrived, and GitHub already makes sharing markdown files easy.
The research and the pace of AI releases made the call clear. I archived Promnia before its official release.
What I took away
- 01AI makes building fast. Knowing whether the problem will still exist in six months is the hard part.
- 02The markdown bet held: skills are markdown files. The product around it wasn’t needed.
- 03Research let me stop with clarity instead of guilt.
