Both make slides with AI. The difference is where they start: SlidesAI starts from a prompt or pasted content, Presmo starts from your document — a PDF, text or a URL — and turns it into a designed, editable .pptx without inventing anything.
Upload a PDF, paste text, or drop a URL.
It understands structure, tightens the text, and picks each layout.
Review every slide, then export an editable PowerPoint.
Presmo reads the whole document — headings, tables, scanned pages — and designs the deck from it.
Every number and claim on a Presmo slide comes from your source. Nothing is made up.
Download a real PowerPoint and finish it in PowerPoint, Keynote or Google Slides.

Your team lives in Google Slides and you want a few slides generated from a paragraph of text inside the deck you are already editing.
You have a whole document, not a paragraph, and you want a complete deck — structure, layouts, tables and figures — as a PowerPoint file that also opens in Google Slides.
Presmo is built for one job: a document goes in, a deck you would actually present comes out. It reads the structure of the document (sections, tables, figures), tightens the prose into slide-sized points, picks a layout per slide, and refuses to add facts that are not in the source. The result is a real .pptx — your file, editable anywhere.
See the full Presmo pricing or the SlidesAI alternative page for more detail.
For turning an existing document into a presentation, yes. For creating new content from a prompt, SlidesAI is designed for that and Presmo is not — Presmo deliberately stays within your source.
Yes. Every deck downloads as a real, editable .pptx that opens in PowerPoint, Keynote or Google Slides.
Yes. Upload the .pptx Presmo gives you to Google Drive and open it with Google Slides — see the PDF to Google Slides page for the steps.
Your first deck is free, full-length and watermark-free. After that you get 3 preview decks a month free, a $7 one-time pack of 5 decks, or Pro at $12/mo for 60 decks.
