An honest comparison of Gamma AI and scid.ai for presentations: scientific source search, DOI references on slides, speaker notes, slide plan, PPTX export and Russian support.
An AI generator of presentations, documents and websites from a short prompt or pasted text. Its strength is design: dozens of themes, adaptive cards, built-in AI images.
scid.ai is a research chat that builds a presentation from scientific sources: it finds peer-reviewed papers or takes yours, shows a slide plan, writes speaker notes with references and delivers a PPTX, in English or Russian.

Gamma designs the text you bring. scid.ai first finds peer-reviewed sources or takes yours, shows a slide plan and puts a DOI under every claim. For a talk that will be checked against sources, that matters more than design.
Yes. scid.ai delivers a PPTX that you can import into Gamma or open in PowerPoint and restyle while keeping the references and speaker notes.
No, slides are built in one universal scid.ai template. There is no theme library like Gamma's: the focus is on content and sources.
Describe the talk topic or pick papers: scid.ai shows a slide plan and builds a PPTX with sources. Free, no card.
