Poster

Description

Poster (poster.sh) is an AI poster generator with a built-in editor for web and social media. Users describe an idea, choose a style and size, and generate a professional poster, then open it in the editor to adjust text, upload images, and fine-tune the layout before exporting as PNG.

The tool offers five generation modes that trade off speed and control, from quick smart generation that expands a short idea into a stronger prompt to exact and professional modes and style fusion for blending directions. A Smart Prompt Optimizer turns basic text into optimized prompts in one click, and posters can be created in multiple aspect ratios optimized for Instagram, stories, flyers, and digital displays. Supporting image tools handle format conversion, compression, and social-media sizing after export.

Poster includes a gallery of AI-generated posters to browse by style and category, and a community where public posters can earn credits through likes and a leaderboard. New users get 5 credits, with Starter and Pro subscriptions adding monthly credits, 4K downloads, more formats, and commercial usage rights, plus one-time credit packs.
