Frequently asked questions
How is a template image API different from a generative AI image API?
A template API changes known fields inside an approved layout; generative AI creates novel visual content from a prompt and is less deterministic.
Can non-developers use the same templates?
Yes. Duply also supports forms, CSV, Zapier, and Make around the same reusable template model.
