Overview
Bento is a PowerPoint alternative in which a whole slide deck is one HTML file. The file carries its own viewer, presenter and editor, so anyone can open it in a browser, edit it, present it or send it on without installing anything. When you save, the file rewrites its own data block with your deck inside. Data sits in a readable JSON block, and an Offline mode blocks updates and collaboration. The app itself is a single file of about 560 KB.

- Deck, fonts, images, charts and editor packed in one HTML file
- Opens and edits in any modern browser, no account or installer
- Saves by rewriting its own data block

Best for
