Best AI Presentation Makers in 2026: Kompyl vs SlidesAI vs Gamma vs Beautiful.ai

AI presentation makers have exploded in 2025–2026. Whether you need to turn a text dump into a polished slide deck or convert a PDF into editable PowerPoint, there are now several strong options. But they differ significantly in output quality, format support, pricing, and workflow fit.

What we compared

We tested five tools — Kompyl, SlidesAI, Gamma, Beautiful.ai, and Tome — across the same set of inputs: a 2,000-word training document, a product FAQ, and a raw URL.

Output quality

Kompyl and Beautiful.ai produced the most template-consistent results. Gamma excels at visual flair but exports to its own format (not native PPTX). SlidesAI works within Google Slides, which limits layout control. Tome focuses on storytelling but forces you into its web editor.

Export formats

If you need native, editable PPTX — the format your team or client actually uses — Kompyl is the strongest option. Most competitors either export static PDFs or lock you into their web editor.

Pricing

Kompyl offers 3 free conversions per day with no signup. Gamma and Tome require accounts for free tiers. Beautiful.ai has no free tier. SlidesAI offers a limited free plan within Google Slides.

Verdict

For teams that need real PPTX output, API access, or course-kit generation, Kompyl is the clear winner. For casual visual storytelling, Gamma or Tome may be more fun. For Google Slides users, SlidesAI is the most convenient.
