Bento: A single HTML file presentation tool with offline editing and collaboration
Key points
- Bento is a presentation tool contained in a single HTML file.
- It supports offline editing, animations, and shared collaboration.
- No installation or cloud login is required for use.
- The project is MIT licensed and open-source.
Introducing Bento
Bento is a new presentation tool designed to encapsulate an entire PowerPoint-like experience within a single HTML file. This approach aims to simplify the creation and sharing of slidedecks, particularly for developers who often use web frontend technologies for presentations.
Key Features and Functionality
The tool operates entirely offline, requiring no installation or cloud login. Users can open the HTML file in any browser to edit, present, print, and save their slides. The default deck size is approximately 560 KB and does not require fetching additional resources once loaded.
Bento includes features like animations and supports shared editing. It can also transform existing PPTX files into Bento slides using AI tools like Claude or ChatGPT.
Collaboration and Sharing
Presentations created with Bento can be shared via email or Airdrop. Recipients only need a browser to view, edit, or participate in live collaboration on the slides. Shared editing is facilitated by an encrypted blind relay, which does not access or store any user data, ensuring privacy.
Technical Foundation and Open Source
Bento is MIT licensed and its code is available on GitHub. It is built using reveal.js along with other libraries, including some custom-developed components. The project was created to address the iterative editing challenges faced when building slidedecks with web frontend technologies and coding harnesses.
