HONG KONG, November 11, 2026: Arca, a brand new desktop app from the crew behind Brevis, opened to the general public at this time. Arca pays individuals for the AI periods they’d in any other case throw away.

A lot of at this time’s information work runs by means of AI instruments. Folks steer a mannequin by means of a process, correcting it, throwing out what fails and maintaining what holds up. Each a type of periods leaves an in depth document of actual work: the back-and-forth, the lifeless ends, the repair that lastly labored. These information pile up by the 1000’s on individuals’s computer systems, and as soon as the window closes, they’re price nothing to the one who did the work. Arca offers that work a price.
The way it works

After putting in the app, customers see the periods Arca has discovered on their machine, previous ones included. They choose a session to add, and Arca anonymises it on their laptop earlier than it leaves, then returns a quote vary. Customers both verify, which sends the session to overview, or withdraw, through which case the add is deleted. Accredited periods are paid weekly.
Arca solely reads periods which can be already on the consumer’s laptop, and it lists every thing it finds. Nothing uploads within the background, and nothing leaves the machine till the consumer picks a session and confirms. Earlier than a session is uploaded, Arca strips names, file paths, account particulars and keys, and additional anonymising runs on Arca’s aspect.
“Each AI session is a document of actual considering and actual work, and till now the one who did that work acquired nothing for it,” mentioned Michael, co-founder and CEO of Brevis. “Arca lets individuals see what their periods are price and determine for themselves what to share. We opened it in small batches first to get the expertise proper. In the present day it’s open to everybody.”
