Mind World

Mind World puts an Improve button and prompt templates on the chat box of Claude, ChatGPT, Gemini, and Perplexity. Click Improve and your rough draft becomes a clear, specific prompt that already knows the context from your past conversations. YOUR MEMORY STAYS ON YOUR DEVICE Mind World quietly saves your AI conversations as you chat, so Improve can reuse what you've already discussed. By default that memory never leaves your browser: conversations, the search index, and your profile live in on-device storage, and the search model runs locally. When you click Improve, only your draft and the few excerpts that match it are used to write the prompt, and nothing is kept. WHAT YOU GET - One-click Improve on Claude, ChatGPT, Gemini, and Perplexity (Alt+Shift+M) - Prompt templates for common tasks - Memory across all four platforms: a chat in ChatGPT can improve a prompt in Claude - Import your full ChatGPT or Claude history once, processed entirely on your device - See exactly which past chats were used, and pick others yourself - Optional personal profile (background, goals, preferences) to personalize prompts - Bring your own Anthropic API key to send Improve straight from your browser to Anthropic - Optional sync across devices if you want your memory in more than one browser - Universal Mode: Improve and templates on any AI chat site you choose PRIVACY CONTROLS - Choose on-device memory (default) or sync across devices, and switch any time - Turn auto-save or chat history off with one toggle - Back up your memory to a file, or delete it from your device in one click - We never sell your data or use your conversations to train AI models Privacy policy: https://mind-world.app/privacy
