Free AI Poster Generator

This AI poster generator creates event and promotional artwork from a description. Tell it the theme, mood, and any text you want, and the free Nano Banana model returns a poster image you can download. It runs in the browser with no account to start, which makes it handy for quick flyers, gig posters, and social promos.

It is great for the visual background and overall layout feel. For precise headlines and dates you may want to add the final text in a design tool, since AI text is improving but not always exact.
