Cue

About Cue

A private prompt library that stays available through ChatGPT, MCP clients, and future CLI agents.

Our purpose

Cue gives your best prompts one dependable home, so they are ready when the work happens instead of getting copied between tools.

Why Cue

Cue is deliberately simple: save complete prompts, connect once, and retrieve the right one in context.

  • Keep complete prompts instead of rebuilding template variables
  • Search your own library from ChatGPT and MCP-compatible clients
  • Fetch the full prompt only when an agent needs it
  • Keep versions and tags close to the prompt itself
  • Use private, scoped connections rather than installing prompts everywhere
  • Work in English, Chinese, or Spanish
Who it is for

Cue is for people and small teams who return to the same high-value instructions while working with ChatGPT, agents, and developer tools.

What Cue includes

Your Cue workspace focuses on a few durable capabilities:

  • A private library for saved prompts

  • Email sign-in with Better Auth
  • Scoped API keys and OAuth connections
  • English, Chinese, and Spanish content
