Open-source AI browser. Switch between ChatGPT, Claude, Gemini, or local LLMs (github.com)

AtlaswebX is an open-source Electron browser that embeds an AI assistant into the browsing experience, letting users switch between cloud models (GPT-based ChatGPT, Claude, Gemini via modular integrations) and local LLMs (Ollama, LM Studio). It packages GPT-4o-mini support out of the box and exposes a modular ai-services layer + ai-v2-router that routes natural commands to handlers for chat, page analysis, element selection and live DOM modifications (e.g., hide ads, recolor, summarize). The app includes practical browser features — multi-tab management, ad-blocking (Cliqz), app shortcuts, drag‑and‑drop layouts, dark mode, and a collapsible AI sidebar — with build scripts for dev/prod and cross-platform packaging. Significance: AtlaswebX blends a programmable browser UI with conversational, context-aware AI, making it easy for developers and power users to script and automate web tasks, inspect pages via an element selector, and perform on-device or proxied model inference. Technical highlights include an Express backend proxy, IPC/WebView sandboxing, secure local storage for API keys (no hardcoded secrets), and a clean modular architecture (ai-v2-chat, ai-element-selector, theme/translation managers) that invites extensions and local/private model workflows. For the AI/ML community it’s a practical reference implementation for integrating models into real-world UIs and for experimenting with hybrid cloud/local inference, privacy trade-offs, and new human-in-the-loop browsing interactions.
