After a request-only early access, the desktop app from the team behind Brevis is open to anyone on Mac or Windows.
HONG KONG, November 11, 2026: Arca, a new desktop app from the team behind Brevis, opened to the public today. Arca pays people for AI events and they drive away. Their AI devices can see the event history stored on their computer, they choose which events to send, filter sensitive information on the device before sending anything, and charge for approved events. Starting today, anyone can sign up with an email address, no application, no waiting list.
Much of today’s intelligence is powered by AI tools. One steers a model through a process, corrects, throws out what falls, and keeps what holds. Each of those sections leaves a record of what actually happened: the back-and-forth, the ones that died, the fixes that worked. These records are collected by the crowd on people’s computers, and when the window closes, there is no reward for the person who did it. Arca’s work is valuable.
How does it work?
Arca works with AI tools already in use, including Claude Code, Codex, Cursor and Claude Desktop. After installing the app, users will see the locations that Arca has detected on their machine, and the previous ones have been installed. They select a location to upload, Arca names it on their computer before leaving, and returns the information range. Users approve, submit the site for review or download, and the upload is rejected. Approved installments are paid weekly.
Arca simply reads the sites on the user’s computer and lists everything it finds. Nothing is sent in the background and nothing leaves the device until the user selects an event and confirms it. Before sending an event, Arca strips names, file paths, account details and keys, and other anonymous information on Arca’s part.
“Every AI conference has a track record of serious thought and real action, and until now there has been no benefit to the person who did it,” said Michael, founder and CEO of Brevis. “Arca lets people see what their events are worth and decide for themselves what to share. We opened it in small portions at first to get the experience right. Today it’s open to everyone.”
Designed for ultimate performance in any field
Arca is designed for anyone who does real work with AI, from code to contract reviews, research and long-term discussions. Events with Claude Opus and Fable, as well as new GPT models in Codex, will be featured today, with more to come. Very short sessions are not necessary and each submission is reviewed before payment. Users can connect to GitHub to reinforce their content, which can increase the value of their events, but is not required.
Arca takes the principle behind Brevis’ verifiable software into new territory: what you can verify is worth more than what you have to trust.
Availability
Arca first opened on October 13 in an application-only way for early access, and introduced users in small batches. As of today’s launch, the invitation is no longer available. Users sign in with an email address or Google account and can get started right away. Arca is free to use and available now for Mac and Windows arca.market.
On November 30, the Arca Launch Challenge added $10,000 to cover the costs of approved events.
