To be fair, Canva's product is uniquely a good fit for Gen AI. Casuals who just want the end result without trying to learn all the complicated photo/video editing techniques.
The Gen AI company they just acquired seems to be making their own model that, amongst other things, can generate coherent and heavily stylized text. For a platform that makes logos, branding, marketing material etc that seems like a natural fit.
Creating elements like that even with Canva's existing tools would generally require a graphic designer or someone with that skillset, or even worse - an agency. All of those options can be prohibitively expensive relative to the benefit they provide.
Yep I use it quite a bit as well as Buffer's AI assistant to help me rewrite texts, or at least give me interesting synonyms. It's probably the only venue where I can say "maybe AI will help people instead of ruining their jobs"
