ChatNest — AI Chat Folders & Prompt Library

Save AI chats to folders, search them fast and reuse prompts with variables on ChatGPT, Claude, Gemini and more. Local-first.

ChatNest is a side-panel organizer and prompt library for people who work with AI chat every day. When a conversation is worth keeping, save it to a folder in one click and add a note in your own words; a few letters later, you can find it again. Save the prompts you reuse as templates, fill in {{variables}}, preview the result, and insert it into the chat box — your existing draft stays put, and ChatNest never sends a message for you. What you can do • Save the current chat to nested folders with your own summary • Search saved titles and notes, and filter by platform • Prompt library with {{variables}}, choices and dates, live preview, and draft-safe insert; type // in the chat box to pull up a prompt • Quote cards that keep only the lines you select • Export JSON or Markdown backups and preview a merge before importing • Interface in English, 繁體中文, 简体中文 and many more languages Supported sites Works on ChatGPT and other popular AI chat sites, with more sites available as experimental (in testing) — feedback is welcome.
