On-device Gemini Nano: runs Chrome's built-in AI model locally so the chat works without internet access.
Privacy by architecture: prompts and responses stay on your machine because nothing is sent to a cloud service.
Multiple interface placements: open the chat in the toolbar popup, side panel, standalone window, or a full browser tab.
Clean chat UI: a left-side toolbar with self-explanatory buttons and tooltips keeps the interface approachable.
No account required: install from the Chrome Web Store and start chatting without sign-up or API keys.
Declared zero data collection: the developer states that user data is not collected, sold, or transferred.
Chrome has shipped an on-device AI model called Gemini Nano for a while now, but reaching it means going through developer flags and a bare-bones demo page. Offline Chat with AI wraps that capability in something you can actually use day to day: a clean chat window with a left-hand toolbar, tooltips on every control, and a proper message history. The extension is published by Jorvi, the developer behind the mybrowseraddon.com collection, and it is offered free of charge.
Because processing happens locally through the browser's built-in AI, the extension has a real privacy advantage over cloud chatbots. Your text does not leave the device, which matters for anything sensitive, and the assistant still answers when you have no connectivity at all. The trade-off is capability: Gemini Nano is a small model optimized for on-device use, so it is better at drafting, rewriting, summarizing, and answering general questions than at deep technical reasoning or working with very long contexts.
One practical detail to know before installing is the first-run experience. The model needs training data downloaded before the chat works, and the listing notes that the extension supports Chrome 138 and later; some earlier documentation referenced Chrome 127, so it is worth confirming your browser version. A second useful touch is placement: you can open the interface in the toolbar popup, the side panel, a separate window, or a full tab by right-clicking the toolbar button. The developer declares that no data is collected or sold, and support runs through the mybrowseraddon.com homepage.
Use the assistant to draft, rewrite, or polish documents when you would rather not paste the content into a cloud chatbot.
On flights or in areas with poor connectivity, use the extension for brainstorming, summarizing notes, and rewriting paragraphs.
Open the side panel next to your document and ask for rephrasings, outlines, or a shorter version of a long passage.
Skip writing your own demo page and experiment with Chrome's on-device model using a polished chat window instead.
