What MoltBrowser is

MoltBrowser is a free, open-source AI browser for macOS, Windows, and Linux, with a browser extension also listed. It runs open models such as Llama, Mistral, Phi, and Qwen locally; its README also documents the option to connect personal keys for OpenAI, Anthropic, Gemini, and OpenAI-compatible endpoints. Its page-aware AI can summarize articles, explain code, extract table data, and translate pages. A browser agent can click, scroll, navigate, and fill forms, with tasks that can be scheduled to run automatically.

The browser stores browsing memory and local AI conversations on the device, according to its maker. Conversation history can be searched, moved in or out as JSON, or deleted in one action. MoltNet routes traffic through Tor and offers exit-country selection. MoltShield blocks ads and trackers, including YouTube ads, and dismisses cookie-consent banners. The maker says MoltBrowser also alters device fingerprint signals and masks the user's IP address. Desktop builds are listed for Apple Silicon Macs, Windows 10/11 x64, and Linux x64; iOS and Android are in development. The project is GPLv3 licensed.
