Canva is great when you want to edit a template by hand, and it also covers presentations, documents and video. If you want an AI to design the product ad for you, starting from your product photo and goal rather than a template, Poster Grammar is built for that. We make it, so here's an honest comparison.
| Canva | Poster Grammar | |
|---|---|---|
| Starts from | A template you pick and edit | Your product and goal; an AI art director picks the layout |
| Design decisions | Yours | Planned by the art director, then editable in the browser |
| Images | Your photos, stock and AI helpers | Generated with the model you choose (ChatGPT Image, Ideogram, Seedream and more), keeping your real product |
| Best for | Any design: social, docs, slides, video | Product ads: social posters, Amazon listing images, sale banners, product photos |
| Free plan | Yes | Yes, 12 starter credits; layouts and the bento tool need no sign up |
Many people use both: Poster Grammar to make the ad, Canva for everything else.
