# AI Captions

> Generate a caption draft from a short topic

Set an OpenAI or Anthropic API key under **Admin → Integrations**, then use **Generate with AI** in the [composer](/social/composing-and-scheduling#composer) to turn a short topic into a caption draft.

This is instance-wide, not per-tenant — one key, set once by the site owner, available to every tenant account. There's no per-tenant "bring your own AI key" option in this version.
