On-device AI

A private assistant powered by Chrome’s built-in AI — answers run on your device

Chat privately, on your device

This assistant uses Chrome’s built-in AI (Gemini Nano). Your questions never leave your browser — so it works offline and shares nothing with a server. History is saved privately on this device, encrypted; switch to “Session only” in the header to have it clear when you close the tab.

Welcome to on-device AI

A private assistant that runs entirely inside your browser. Here’s what to know before your first message.

Checking your browser…

01
Nothing leaves your device
Your messages are answered by a model running locally in Chrome. No account, no server, no tracking. History is saved privately on this device, encrypted — or switch to session-only mode anytime.
02
First run downloads the model
The very first question may take a minute while Chrome downloads the on-device model (Gemini Nano). After that it’s instant and works offline.
03
Then just ask
Type a question below, or tap an example to start. It’s a small model — great for quick help, brainstorming and rewriting, not live facts.

Answers are generated by a general-purpose AI model running entirely on your own device (your browser’s built-in AI). No Telesto Tech corpus, retrieval, or server is involved, so answers carry no citations and may be inaccurate, incomplete, out of date, or entirely fabricated. They are general information only — NOT legal, medical, financial, engineering, or other professional advice — and nothing here creates a professional, advisory, or fiduciary relationship. On-device models are small and have no access to current or external information; you are solely responsible for independently verifying every answer before acting, and you rely on it entirely at your own risk. To the fullest extent permitted by applicable law, Telesto Tech disclaims all liability for any use of, or reliance on, these answers.
