Where: Inside the composer (AI Image, AI Video) and the calendar sidebar (the AI generate button)
Availability: Postiz Cloud, Standard plan and above. The image generator needs Team and above. On self-hosted installs these features need AI keys configured on the instance.

​
AI images

AI Image in the attachments bar takes a prompt and a style, and drops the result straight into the post. Generated images land in your media library too, so you can reuse them.

​
AI video

AI Video offers the video generators available on your instance:
  • Veo3, prompt-driven video generation, optionally seeded with media.
  • Image and text slides, which turns images plus narration into a video.
You also pick an orientation: vertical for stories and reels, horizontal for everything else. Pick it correctly the first time, since re-generating costs another credit. Video generation is slow. If it outlives the composer session, Postiz tells you the result will appear in your media library when it finishes.

​
Generating whole posts

The AI button in the calendar sidebar generates posts rather than media. You give it a subject and it researches, picks an angle, writes, optionally generates pictures, and finds a time to post. You choose:
  • Output format: a short post, a long post, a thread of short posts, or a thread of long posts.
  • Tone: personal voice or company voice.
  • Pictures: whether to generate images alongside the text.
It streams its progress and drops finished posts onto the calendar as drafts, so nothing publishes without you reviewing it.

​
Credits

AI images and AI videos are metered separately on Postiz Cloud.
  • Each generation spends one credit.
  • A generation that fails does not cost you a credit.
  • Credits reset monthly, on the anniversary of your subscription rather than on the first of the month.
  • Running out gives you an error pointing at the billing page. See Limits for the per-plan allowances.
On self-hosted Postiz: there are no credits, but AI features only work if the instance has the relevant API keys configured. Without them the buttons either do not appear or return nothing.

​
The agent

Beyond the composer, Postiz has a full AI chat at Agent that can schedule posts, generate media, and open the composer prefilled. See The AI agent.
