Skein — Folders, Prompts & Export for ChatGPT, Claude & Gemini

Organize ChatGPT, Claude & Gemini chats into folders. Prompt library, full export, instant search — all local, no account.

Skein keeps all your AI conversations in one calm, organized place — across ChatGPT, Claude, and Gemini. If your chat sidebar has become an endless scroll, Skein adds folders, search, and a prompt library right where you work, so you can actually find that conversation again. What you can do - Organize with folders — drag and drop any chat where it belongs. - Work across ChatGPT, Claude, and Gemini from one consistent sidebar. - Save reusable prompts with {{variables}} you fill in when you insert them. - Generate prompts with AI using your own OpenAI API key (optional). - Search across your conversations by title. - Export a conversation to Markdown, or back up your whole folder structure to Markdown/JSON. Private by design - No account. No sign-up. Nothing to log into. - Everything is stored locally in your browser. Your data never touches a server. - No tracking. No ads. Optional AI features - Skein can help you write prompts using your own OpenAI API key. - The key is stored only in your browser and sent directly to OpenAI — never to Skein. - This feature stays off until you add a key. Free and Pro - Everything you need is free: folders, search, the prompt library, AI prompt generation (with your own key), and full data backup. - The free tier includes up to 5 folders, 5 saved prompts, and 5 full-conversation exports. - Pro (coming soon) removes those limits: unlimited folders, unlimited prompts, and unlimited conversation export. Install Skein, open ChatGPT, Claude, or Gemini, and start filing chats into folders in seconds.
