Sibby is here!
An AI that knows you. Models that don't.
Sibby keeps your memory on your device. When you ask, it talks to Claude, GPT and other models for you (choosing the most appropriate) - anonymously or sealed to hardware your browser verifies - and sends only what that question needs.
No account. No server copy of you. Tap any answer to see exactly what left.
Thanks for flagging! Not a topic limit: a credit bug made that request fail before it reached the model. Fixed and your wallet repairs itself, so just try again.
Heads-up: Sibby doesn't browse the web yet, so live news or prices won't be up to date. Great for everything else though!
ChatGPT/Claude memory: lives on their servers.
Sibby memory: lives in your browser, encrypted.
Same kind of personal answers.
Different leash.
Passkey lock. Backup file. You're in charge.
Sibby remembers you on your device. The AI models only get what that one question needs.
No account. No cloud copy of your life.

Sealed questions don't trust the cloud.
Your browser asks the enclave for a hardware proof, verifies it, then encrypts to that key.
If anything doesn't check out, nothing is sent.
Privacy that fails closed.
Every question takes one of three paths:
โข On your device - nothing leaves.
โข Anonymous - best models, no name / account / IP.
โข Sealed - encrypted to hardware your browser verifies
You can see which path ran under every answer.

Sibby already knows your name, job, age, partner.
What actually left the device: city + diet.
Everything else stayed home.
Thatโs the product.
