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

Tracking since Jun 4, 2026.

Changelog

• Jun 9, 2026
  description

  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.
  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.
  
  Free and Pro
  
  Free includes folders, search, the prompt library, and backup export.
  Pro raises the folder and prompt limits and unlocks full conversation export — coming soon.
