Gemini Collector
Back up all your Google Gemini conversations & AI-generated media locally
Native desktop app for macOS & Windows · Multi-account · Light / Dark theme
Gemini Collector turns your entire Gemini chat history into a local offline archive — every conversation, uploaded attachment, and AI-generated image, music track, video, and report is saved to your machine, ready to browse and export anytime. A one-click alternative to Google Takeout for backing up Gemini.
