Hey Product Hunt, Nicolas here. I work on Arca at Brevis.
The idea is simple. If you use Claude Code, Codex or Cursor every day, your computer is full of old sessions: whole conversations of you and the model working through real problems or even just a lot of wrong turns. Those logs mostly just sit there. Arca lets you get paid for all your unused abandoned sessions.
How it actually works:
Install the app (Mac or Windows) and sign up with email or Google.
It lists the sessions your tools have already saved. It doesn't record anything new, and nothing uploads unless you pick it.
When you pick a session, Arca removes names, file paths, account details and keys on your computer before it uploads.
You get a quote range. Submit the session for review, or withdraw it if the price isn't worth it to you.
Approved sessions are paid out weekly.
It's mostly developers using it right now, but writing and research sessions in Claude Desktop can count too.
A bit about us: we're the team behind Brevis, where we build zero-knowledge proof systems, which let you prove something is correct without exposing the data behind it (nearly 400 million proofs generated so far). Verifying work while keeping sensitive details out of it is what we do every day, and it's the same thinking behind how Arca handles your sessions.
What I'd really like to hear: what would make you comfortable uploading a session, what's unclear, and which tools you'd want supported next.
