Integrating ChatGPT into your browser deeply, everything you need is here
Provides context-aware ChatGPT integration across search engines, documentation sites (GitHub, Stack Overflow, Reddit), and video platforms through site-specific adapters, while supporting multiple LLM backends (GPT-3.5/4, Claude, Ollama, self-hosted via custom API endpoints). Features floating chat windows with multi-branch conversations, selection-based tools for translation/summarization/code analysis, and page summarization—all as a cross-browser extension (Chrome, Firefox, Edge, Safari) with zero data collection by design.
