Arca Desktop App Opens to Everyone on November 11: Mac and Windows, Pays for Approved AI Sessions, With a $10,000 Launch Challenge Through November 30
Arca, a desktop app from the team behind Brevis, opened to the public on November 11, the company announced. Arca first opened on October 13 in invite-only early access, admitting users in small batches. Starting today, anyone can sign up with an email address, with no invite and no waitlist.
Arca pays people for the AI sessions they would otherwise throw away, according to the release. It finds the session history their AI tools already keep on their computer, lets them choose which sessions to submit, strips sensitive details on the device before anything is uploaded, and pays for the sessions that are approved.
The company said Arca works with the AI tools people already use, including Claude Code, Codex, Cursor and Claude Desktop. After installing the app, users see the sessions Arca has found on their machine, past ones included. They pick a session to upload, and Arca anonymises it on their computer before it leaves, then returns a quote range. Users either confirm, which sends the session to review, or withdraw, in which case the upload is deleted. Approved sessions are paid weekly.
Arca only reads sessions that are already on the user computer, and it lists everything it finds, the company said. Nothing uploads in the background, and nothing leaves the device until the user picks a session and confirms. Before upload, Arca strips names, file paths, account details and keys, with further anonymising on Arca side.
Sessions with Claude Opus and Fable, and with the latest GPT models in Codex, qualify today, with more to come, the company said. Very short sessions do not qualify, and every submission is reviewed before it pays. Users can connect GitHub to strengthen their profile, which can raise the value of their sessions, but it is not required.
Michael, co-founder and chief executive of Brevis, said in the release that every AI session is a record of real thinking and real work, and that Arca lets people see what their sessions are worth and decide for themselves what to share.
Arca is free to use and available now for Mac and Windows at arca.market. Through November 30, the Arca Launch Challenge adds $10,000 in prizes on top of regular payouts for approved sessions.
