  • Folders, search, and prompt library that the native ChatGPT UI lacks
  • Bulk export to PDF, Markdown, JSON, and TXT
  • Prompt queue lets you chain sequential prompts unattended
  • Conversation tree map makes branched chats navigable
  • Mature with 100K+ users and active development
Cons
  • Pricing and managed-cloud story not yet published
  • Early-stage project with thin public documentation
  • Self-host operational burden vs hosted competitors
  • Only works with ChatGPT, not Claude or Gemini
  • Breaks occasionally when OpenAI ships UI changes
  • Some advanced features gated behind Pro
  • Browser extension means desktop Chrome/Edge only
