SpaceMind

Organize AI chats and build reusable prompt workspaces for ChatGPT, Claude, Gemini, DeepSeek & Mistral. Local-first, no account.

SpaceMind organizes your AI conversations into named "spaces" — one per project, research thread, or personal context — across ChatGPT, Claude, Gemini, DeepSeek, and Mistral. Everything stays on your device. No account, no telemetry, no servers. The code is MIT open source. — FEATURES — • Spaces — group conversations by project. Pin favourites, add an emoji + note, reorder freely, filter by tags. • Cross-platform — one inbox for ChatGPT, Claude, Gemini, DeepSeek, and Mistral. A single space can hold threads from any of them. • Real-time sidebar capture — as you chat on a supported site, SpaceMind silently records new conversations from the page's own sidebar. No polling, no API calls. • One-keystroke filing — press Cmd/Ctrl+Shift+K (or click the floating button) on any supported site to file the current conversation into a space. • ZIP import — drop your official ChatGPT or Claude export and search every message you've ever sent, fully locally. • Full-text search — across titles and message bodies, with proper Chinese/CJK tokenization. star. • Command palette (Cmd/Ctrl+K) — every action one keystroke away. • Dark mode, English + 简体中文, JSON export/import. — PRIVACY — SpaceMind stores everything in your browser's local IndexedDB and chrome.storage.local. It makes no outbound network requests, integrates no analytics or ad SDKs, and sends nothing to OpenAI, Anthropic, Google, DeepSeek, Mistral, or us. Content scripts only READ the page DOM inside your own tabs to identify your conversations and render the overlay — they never modify the page or call any service's API. Permissions: "storage" plus host access to the five supported chat sites only. Open source: https://github.com/tashuo/spacemind Privacy policy: https://github.com/tashuo/spacemind/blob/main/PRIVACY.md
