Comparison · updated October 2026
Chekmate vs Gamma
Gamma is an AI tool that makes presentations, documents, websites and social posts from a prompt, with custom themes for your brand.
Short answer
Gamma makes decks; Chekmate checks them. Gamma applies your theme while you create, and can import and export PowerPoint. Its website doesn't list checking a deck against a brand. Chekmate checks any deck, including ones exported from Gamma, against each client's brand, and lists what's off slide by slide.
Feature by feature
The Gamma column shows what Gamma's own website lists, checked on 26 October 2026. "Not listed" means we couldn't find it on their public website that day, not that their product can't do it. Spotted something out of date? Email hello@chekmate.app and we'll correct it.
