What is JUWEL?
JUWEL is an AI with her own computer. Hand her a whole job — clear an inbox, audit a bill, ship a migration, plan a week — and she works across her own mail, files, calendar, browser, IDE and terminal to finish it, checking with you before anything consequential happens.
What is JUWEL OS?
JUWEL OS is her computer: an agent-native operating system with chat, files, mail, calendar, a browser, an IDE, a terminal, and a ledger. You can watch her work window by window, and step in at any point. It runs in your browser — start at juwel.ai/os.html.
How much does JUWEL cost?
Free includes everyday JUWEL with a monthly action allowance. Pro is $20/month or $200/year with unlimited everyday actions and every profession cut. Enterprise is custom. Verifying receipts is free for everyone, forever — no account needed.
Will she act without my permission?
No. Consequential actions — sending, paying, filing, deleting, shipping — always pause for your explicit approval before anything leaves your machine.
What is a receipt?
Every action JUWEL takes is signed (ECDSA P-256) and hash-chained (SHA-256) into a receipt. You can check any receipt offline with an open-source verifier that Vext Labs does not control: npx @vextlabs/stoa-verifier. Change one byte and verification fails.
Do I need an account to verify receipts?
No. The verifier is open source, runs offline, and never calls Vext Labs. Anyone can check any JUWEL receipt — customer or not.
Which AI model powers JUWEL?
JUWEL is substrate-agnostic: she routes each job to the model that fits it, and the receipt records what actually ran. You can also point her at your own endpoint.
What are the 19 facets?
Facets are the domains of your life JUWEL turns to — nineteen of them, from Cyber, Code and Language to Medical, Legal, Finance, Creative and more. One AI, one core, whatever the job needs.
Is my data private?
Your OS instance is yours: files, memory and keys live with your instance, and your signing key is generated on your device. We don't sell your data. See the privacy policy for the full picture.
What is Vext Labs?
Vext Labs, Inc. is the American AI research lab behind JUWEL. Two programs: STOA, the receipt system that ships today, and CIP, continual-learning research toward memory that grows without forgetting — validated at toy scale so far, published either way.
