ChatIndex

Never lose a single important message, chat, or context across any AI tool you use with chatIndex

🚀 ChatIndex – Never lose a single important message, chat, or context – across any AI tool you use. Your AI chats contain valuable ideas, solutions, research, and insights. But every AI platform still forces you to scroll endlessly. Folders don't sync across tools. Context gets lost when you switch. ✅ ChatIndex fixes that – completely. It adds a powerful search & organization layer across ChatGPT, Claude, Gemini, DeepSeek, and Perplexity. Index everything. Search anything. Move conversations between AIs without losing context. 🎯 Stop losing insights. Start navigating your AI conversations like a structured workspace. ✨ WHAT'S NEW & FULLY UPDATED FEATURES 🔎 1. Cross-Platform Keyword Search Search across all your conversations on every AI platform at once. Type a keyword – ChatIndex instantly shows every match from ChatGPT, Claude, Gemini, DeepSeek, and Perplexity. Jump directly to the exact message. No more "which chat was that in?" No more scrolling. 📁 2. Cross-Chat Folders (Across All AIs) Create folders and drag chats from different AI platforms into the same folder. Keep research, coding, writing, or client work together – even if they came from different tools. ChatGPT has folders. Claude has folders. Gemini, DeepSeek, Perplexity? None do. And none talk to each other. ChatIndex makes all of them work as one. 🔄 3. Continue In – Move Conversations Between AIs Want a second opinion from another AI?
