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.

Key features

  • 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
  • Readable JSON data with no binary format
  • Offline mode that blocks updates and collaboration

Best for

People who want slide decks that stay self-contained and readable years later, and can be shared with anyone who has a browser.
