Why AskSia

The PowerPoint summarizer that respects every slide.

Most slide chatbots cap at 30 slides or skip speaker notes. AskSia handles 100 decks per session with slide-by-slide citations and speaker note extraction.

Native PPTX and Google Slides

AskSia parses PPTX and PPT decks natively (titles, bullets, body text, tables, charts) and reads public Google Slides via shared links. No conversion to PDF, no formatting loss.

PPTX plus Google Slides

Slide-by-slide summary

AskSia gives a structured summary for every slide, with the slide title, the key claim, and supporting points laid out clearly. Useful for fast review and converting slides into study guides.

Per-slide summaries

Speaker note extraction

AskSia reads the speaker notes attached to each slide and includes them in the summary, useful for understanding the professor's full delivery (not just what is on screen).

Speaker notes included

Cited to the exact slide

Every claim in the summary carries a [N] marker with a slide number. Hover to see the source slide preview. Click to jump into the deck at that slide.
