We compared the two tools on what matters: .pptx file quality, price, language and ease of use. Our honest verdict is below.
Designed for French: paste text or import a PDF/DOCX and get a native, editable .pptx in minutes, from $14.90/month.
A general-purpose presentation and web page generator with an English interface and PowerPoint export available on the free plan.

Prezto produces an editable .pptx directly, even with the free offer. Gamma also exports .pptx, but its native format is an interactive web page: export retains most formatting without always reproducing it exactly, and keeps a watermark on the free plan.
Prezto is designed and written for French-speaking users throughout the experience. Gamma can generate French content, but its interface remains in English.
Prezto charges a fixed subscription from $14.90/month (10 presentations on Pro), with a published allowance: one generation counts as one presentation, up to 30 slides and 10 illustrations. Gamma's credit use varies by feature, making the actual cost less predictable.
If you work in French and your final deliverable is a PowerPoint file ready to refine, Prezto gets more directly to the point: document import, native .pptx export and fixed, predictable pricing.
Gamma remains relevant if you need a broader presentation tool, with an extensive template library and uses beyond slideshows (sites, documents). The simplest approach: test both on the same document; your first Prezto presentation is free.
Yes: export your content from Gamma as .pptx or text, then import it into Prezto to regenerate your slides with your chosen theme.
Your first presentation is free: compare the result with no credit card required.
