What MoltBrowser is
MoltBrowser is a free, open-source AI browser for desktop systems, with an embedded on-device model and privacy features. Its page-aware AI can summarize articles, explain code, extract table data, and translate pages. It runs open models such as Llama, Mistral, Phi, and Qwen locally; its README also documents bring-your-own-key support for OpenAI, Anthropic, Gemini, and OpenAI-compatible endpoints. Its agent can click, scroll, navigate, and fill forms, and tasks can be scheduled to run automatically. The browser keeps browsing memory on the device, and its conversation history can be searched, imported or exported as JSON, or erased in one click. MoltNet routes traffic over Tor and offers an exit-country choice; MoltShield blocks ads and trackers, including YouTube ads, and dismisses cookie banners. The maker says it scrambles device fingerprint signals and masks the user's IP address. Builds are listed for macOS on Apple Silicon, Windows 10/11 x64, and Linux x64. iOS and Android are in development.
