TL;DR
A new tool called Bento allows users to build, edit, and collaborate on full PowerPoint presentations within a single HTML file. It aims to simplify slide management and improve accessibility.
Bento is a new web-based tool that enables users to create, edit, view, and collaborate on an entire PowerPoint presentation within a single HTML file. This development aims to streamline presentation workflows by consolidating all content and data into one portable, easily shareable format, making it particularly relevant for teams working remotely or in environments with limited software support.
Developed over the past few months, Bento leverages modern web frontend technologies to embed a complete slide deck into one HTML file. Users can perform all typical presentation tasks—adding, editing, and viewing slides—without needing multiple files or external software. The tool also supports data integration and real-time collaboration, addressing common pain points in traditional presentation workflows.
According to the creators, Bento is designed to be lightweight and easy to distribute, with the entire presentation stored as a single file that can be opened in any web browser. This approach aims to reduce dependency on proprietary presentation software like PowerPoint or Google Slides, offering a more flexible and accessible alternative.
Implications for Presentation Collaboration and Accessibility
This development could significantly impact how teams collaborate on presentations, especially in remote or distributed work environments. By consolidating all presentation data into one HTML file, Bento simplifies sharing and version control, potentially reducing compatibility issues and streamlining workflows. It also opens possibilities for integrating dynamic data and custom features directly into slides, enhancing flexibility for users who need tailored presentations.
Web Technologies Transforming Presentation Tools
Over recent years, there has been a trend toward web-based presentation tools that leverage HTML, CSS, and JavaScript to improve flexibility and accessibility. Tools like Google Slides and others have shifted collaboration online, but many still rely on cloud storage and proprietary formats. Bento distinguishes itself by aiming to package an entire presentation into a single, portable HTML file, reducing reliance on external platforms and software. This approach aligns with broader efforts to make digital content more portable, customizable, and collaborative.
“Our goal was to create a one-file solution that combines the power of traditional slide decks with the flexibility of web technologies, making collaboration and editing seamless.”

What Limitations or Challenges Remain for Bento
Details about Bento’s current feature set, such as support for complex animations, multimedia, or offline editing, are still emerging. It is also unclear how well the tool handles large or highly detailed presentations, or how it manages real-time collaboration at scale. Additionally, the extent of user customization and integration with existing workflows remains to be seen.
