Introducing Arca: Turn Wasted Vibes Into Income

TL;DR

Arca is a new app from the Brevis team that pays you for the AI sessions you’d otherwise throw away. Request an invite, install Arca, and keep working the way you already do. It finds the sessions your AI tools already keep on your machine, strips sensitive details before anything is uploaded, shows you a quote before you commit, and pays out in USDC weekly for the sessions you choose to submit. Early access opens today, in small batches.

The trail you leave behind

A few years ago, you did every step yourself. Now you steer a model through it: prompting, correcting, throwing out what doesn’t work, keeping what does.

That new way of working leaves something behind that never existed before. Every session is a detailed record of real work: the back-and-forth, the dead ends, the corrections, the version that finally holds up. Code, a contract review, a research brief, a long working conversation. Multiply that across everything you touch, and there are thousands of these sessions sitting on your drive.

You paid for the tokens, you did the work, and the moment you close the window, all of it is worth exactly nothing.

Arca is the first thing that pays you for it.

Introducing Arca

Arca is a desktop app that turns those sessions into income. It reads the session history your AI tools already keep on your machine, past sessions included, quotes the ones you upload, and pays you in USDC for the ones you choose to submit. Nothing about your workflow changes, and nothing leaves your machine unless you decide it should.

How it works

Install and work like normal. Install the Arca app and keep working the way you already do. It finds the AI sessions already saved on your machine, past ones included, and nothing is uploaded.
Upload and get your quote. Pick a session and upload it. Arca strips sensitive details on your machine before anything leaves, then comes back with a quote range.
Take the offer, or walk away. Confirm and it goes to full review, paid in USDC to your wallet weekly once approved. Withdraw and your upload is deleted immediately.

Nothing leaves until you send it

The obvious question about an app that can see your AI sessions is what happens to them. Here is the whole answer.

Arca only reads sessions that are already on your machine, and it lists them so you can see exactly what it found. Nothing is uploaded until you pick a session and confirm. Before one leaves, Arca strips things like names, file paths, account details and keys, and we run further anonymising on our side before your data is used in any way. The quote comes back after upload, and if it doesn’t work for you, you withdraw before confirming and your upload is deleted immediately.

Nothing uploads in the background. Nothing you don’t explicitly submit ever leaves your machine.

What it takes to earn

Arca rewards real work with real AI tools, in any field. A few things to know before you start:

Invite-only for now. Access opens in small batches. Request an invite on the site, and your code arrives by email if you’re approved.
Qualifying models. Sessions with Claude Opus and Fable, and with the latest GPT models in Codex, qualify today, with more to come. The app only lists sessions that qualify, so there is nothing to guess.
Expertise pays. Your track record can boost your rate. Developers can connect to GitHub; the more your history shows real work, the higher your sessions are valued.
Quality over volume. Stronger, more complete sessions earn more than noise. Very short sessions don’t qualify, and every submission is reviewed before it pays.

Built by Brevis

Arca is built by the team behind Brevis. If you know us for zero-knowledge infrastructure, the connection is simple. Everything we ship starts from the same conviction: things you can verify are worth more than things you have to trust. Arca carries that standard into a new domain, where verifiable computing establishes what your work is worth. It starts with the work you already do every day.

Get started

Arca is open today in invite-only early access. The app is free to use and available for Mac and Windows. You’ll need an invite, an AI tool you use for real work, and a wallet for payouts.

Request an invite, open the app, and the next session you’d have thrown away might be the first one that pays you.

About Brevis

Brevis is a verifiable computing platform powered by zero-knowledge proofs, serving as the infinite compute layer for Web3 and beyond. Applications can offload expensive computation off-chain while proving every result on-chain. The Brevis stack includes Pico zkVM for general-purpose computation, which in its 3.0 release proves Ethereum blocks in real time on a single machine with 4 GPUs and 100 bits of provable security; the ZK Data Coprocessor for trustless access to historical blockchain data; Vera for ZK-proven media authenticity; and ProverNet, the decentralized marketplace for ZK proof generation, live on mainnet. To date, Brevis has generated nearly 400 million proofs across 50+ protocols on 14 blockchains.
