inbrowser.chat is a private AI chat that runs entirely on your device. It uses Chrome's built-in LanguageModel API (Gemini Nano), so every message is processed locally. No server, no API key, no network request. Chats stay in localStorage and work offline. Free, with no monetization planned. It's a demo of what a local LLM can do. Note by Google: this LLM is for summarizing, classifying or rephrasing text, NOT for use cases needing factual accuracy like answering knowledge questions.
