Microsoft Designer is a browser-based AI graphic design app that generates social media posts, invitations, posters, icons, and stickers from text prompts, then lets you edit the output with tools like background removal. The workflow is one-shot: describe what you want, pick from generated options, adjust. For a non-designer who needs a Teams banner or a LinkedIn post on a deadline, that loop is fast. The ceiling arrives quickly — there is no multi-page layout, no brand kit that travels with you outside paid Microsoft 365 features, and generation credits are capped on the free tier. Teams with ongoing design volume hit the credit wall and either upgrade or switch to Canva.
