Bento: a full PowerPoint workflow in a single HTML file
The team behind Bento says it packs an entire slide workflow into one offline HTML file: edit, present, print, save, and even live-collaborate in the browser.
- No install, no cloud login, and no data fetches once loaded
- Decks are lightweight by default, around 560 KB
- Works by sharing the file itself over email or AirDrop
- Supports transforming existing PPTX files with Claude or ChatGPT
- Uses an encrypted blind relay for collaboration; the relay cannot read the slide data
- MIT licensed, built on reveal.js plus other libraries
