Bento - An entire PowerPoint in one HTML file

What it does

Bento is a tool that allows creating, editing, viewing, and collaborating on presentations in a single HTML file. The entire deck, viewer, editor, and assets are embedded in one self-contained file. It features morph transitions, live charts, structured data tables, and self-saving capabilities. The file checks for updates at launch via a signed manifest but can be configured to disable this.

Who it is for

Bento is designed for anyone who needs to create and share presentations without relying on external software or cloud services. It is particularly useful for developers, designers, and technical users who prefer a portable, self-contained file format. The tool is also suitable for teams that want to collaborate on presentations without requiring accounts or installations.

Why it matters

Traditional presentation tools like PowerPoint or Google Slides require software installation or internet connectivity. Bento eliminates these dependencies by packaging everything into a single HTML file that works in any modern browser. This approach ensures portability, longevity, and privacy—the file is yours forever, with no servers required. The live data features (charts, tables) and morph transitions provide a modern, interactive presentation experience.

Launch signal

Bento was launched as a Show HN on Hacker News, indicating early-stage public availability. The tagline "An entire PowerPoint in one HTML file" clearly communicates its unique value proposition. The product appears to be functional and available for use at bento.page/slides.

Brand and naming

The name 'Bento' is short, catchy, and evokes the idea of a neatly organized, all-in-one container, which aligns well with the tagline 'An entire PowerPoint in one HTML file.' However, the name is generic and may face domain availability issues (bento.com is likely taken). The positioning is clear: it's a tool that packages presentations into a single HTML file, but the name doesn't directly hint at presentations or slides, which could reduce memorability for the specific use case.
