What it does
Poster Design is an online image editor you run on your own server and use in a web browser. You can drag text, pictures, shapes and QR codes onto a canvas to make posters, online shop product images, long article graphics and video or social media covers.
It includes AI tools. It can create images and write marketing text, and it can remove the background from a photo in one click. The background remover runs inside your browser. The text and image tools connect to an online AI service that an administrator sets up using an API key (a password-like code from the AI provider).
It also comes with user accounts, saved designs, a template library, and an admin area for managing templates, fonts and users. It can open PSD files (Photoshop designs) to help turn them into templates. The makers also offer a paid business version with custom development.
Who it's for
People or teams who want their own online poster and graphics editor, and developers building a design website.
