What is matrixon-agentic-browser?

MATRIXON Agentic Browser is an open-source desktop web browser with a built-in AI assistant that runs entirely on your own machine, no internet connection is needed for the AI, no account to create, and no API keys to manage. It is built on Electron (a framework for creating desktop apps using web technologies) and uses llama.cpp to run language models locally, meaning all AI processing happens on your hardware and your data never leaves your device. The AI integrates into the browser in three ways. First, there is an AgentPanel, a sidebar assistant that can take actions on your behalf: searching the web, reading the current page, or navigating to a URL. Second, there is a full-page AI Chat with multi-turn conversation support, file attachments, and LaTeX (math formula) rendering. Third, there is an AI Search mode that retrieves web results and has your local model summarize them. The browser also includes tab management with groups, an omnibox (combined address and search bar), a local encrypted password vault with autofill, and light, dark, or system-following themes. The interface is available in English and Russian. A default model (Llama-3.2-1B-Instruct in a compressed GGUF format) is bundled with the repository, so no extra downloads are required to get started. Swapping to a different language model is straightforward: place any GGUF-format model file in the app's LLM folder and restart. The primary supported platform is Windows 10/11.
