Does This Idea Exist

Check whether the thing you're about to build already shipped.

A startup directory that checks itself. Entries get seeded from a repo or a URL, profiled by an LLM, then approved by a human. Every week it re-checks whether they're still alive. Three failed checks and an entry is marked dead.

Directories rot. Most of them are a pile of dead links nobody has looked at in two years.

What's in it

  • Client-side fuzzy search with category, year and status filters
  • Seed an entry from a GitHub repo or a website via LLM profiling
  • Weekly automated liveness checks behind a human approval gate
  • Local first. No accounts, no tracking, no external requests
