Kompyl vs SlidesAI: Free AI Slide Generators Compared
SlidesAI works inside Google Slides; Kompyl works everywhere. We compare output quality, supported formats, pricing, and developer features.
SlidesAI is a popular Google Slides add-on that generates presentations from text. Kompyl is a standalone AI tool with 800+ document transforms. Both are free — but they target very different users.

|---|---|---|

| Output format | Native PPTX download | Google Slides only |
| Input types | Text, URL, PDF, DOCX, PPTX | Text only |

Where SlidesAI shines
If your entire workflow lives inside Google Workspace and you just want a quick text-to-slides shortcut, SlidesAI is convenient. It integrates directly into the editor you already use.
Where Kompyl wins
Kompyl accepts far more input types, generates native PPTX (not Google Slides), includes 800+ additional tools, and offers a developer API. For teams that need to process PDFs, DOCXes, or batch-convert documents, SlidesAI simply can't keep up.
Our recommendation
Use SlidesAI for quick Google Slides drafts. Use Kompyl for anything that needs to leave Google's ecosystem — client deliverables, LMS content, API-driven pipelines, or professional presentations.
