AI Toolbox is the missing layer on top of ChatGPT, Claude, Gemini and Grok: folders and subfolders, full-text search across every conversation (even all four platforms at once), a prompt library with // insert and multi-step chains, bulk export to Markdown/PDF/JSON, bookmarks, and a live context meter. One install covers all four AIs. Local-first: your chats stay in your browser. Trusted by 40,000+ users in 150+ countries, rated 4.5 stars on the Chrome Web Store.
