What it does
Creates, edits, presents, and shares slide decks that live entirely inside one self-contained HTML file, with built-in charts, animations, speaker view, PDF export, and E2EE live collaboration, all running offline in any modern browser with no install or account.
Who it’s for
Individuals and teams making presentations - developers, founders, educators, and knowledge workers who want portable, local-first, offline decks that recipients can open and edit in a browser without PowerPoint or a cloud login.
Why it entered the Feed
Admitted from a top-ranked Show HN launch (~1k points, #1) presenting a concrete, working product: an MIT-licensed, open-source PowerPoint alternative distributed as a single ~560 KB HTML file with editor, viewer, and collab built in, confirmed by the official site bento.page.
