PowerPoint persists because it connects many organizational routines: template governance, desktop editing, speaker notes, file exchange, meeting rooms, procurement, and colleagues who can repair a slide minutes before a presentation. Evaluating alternatives only on design freedom understates those surrounding capabilities.
htmlslides proposes a different center of gravity. The source is HTML produced by an AI coding agent or an author. Playback happens in the browser. Distribution can use a link or embed. This is especially coherent for product narratives, technical explainers, and public-facing decks whose audience already lives on the web.
The strongest case for change appears when the old workflow's file assumptions are the problem. Attachments create version confusion, static screenshots flatten a software story, or a deck belongs inside a site. The weakest case is aesthetic boredom. A new tool cannot fix unclear thinking, missing evidence, or governance that nobody owns.
