Bento Page

Bento Page is a local-first, AI-native office suite that fits inside a single HTML file. Where most presentation tools sell you a SaaS subscription, an account, and a closed document format, Bento Page ships the document, the editor, and the player in one self-contained ~640 KB file. The deck, the slide sorter, the chart engine, and the collaboration runtime all live inside the same artifact — drop the file anywhere and it runs.

The product positioning of Bento Page is unusually direct: "the boring deck is dead. One file killed it." That single line captures the entire value proposition. A PowerPoint file that previously demanded Microsoft Office, a Google account, or a Keynote license can now be replaced by a Bento Page file that opens in any browser, runs offline, and embeds animation, video, live charts, and web-grade design without any external service. The file is also the document format itself — it is plain JSON inside HTML, which means it can be diffed, version-controlled, edited in any text editor, and reconstructed programmatically.

Bento Page is the first app of a planned office family. The slides app is already shipping; upcoming Bento Page apps include bento/spaces for notes, bento/dash for sheets and tables, and bento/vault for secure storage. Every app in the Bento Page family shares the same local-first philosophy: no account required, no telemetry by default, MIT licensed, and open source on GitHub. The slides app itself is built on top of reveal.js, Moveable, and Selecto (all MIT), plus a custom rendering engine for morph transitions and live charts.

For knowledge workers, designers, founders, and educators who are tired of paying monthly subscriptions to read their own files, Bento Page is the most interesting alternative to land on the open web in years. The single-file model is not a gimmick — it is a structural argument about who owns your documents, and Bento Page has bet the entire product on that argument.
