A team has developed Bento, a tool designed to streamline slide deck creation using web frontend technologies, addressing the inconvenience of manual code edits.

Bento is a self-contained HTML file that includes editing, presentation, printing, and collaborative features, all functioning offline without installation or cloud login. The default deck is approximately 560 KB and requires no external fetching once obtained. Users can open the file in any browser to edit, present, print, and save slides. Sharing is simple via email or Airdrop, with recipients only needing a browser to access and edit presentations, even enabling live collaboration.

Bento can transform existing pptx files into its slide format using AI tools like Claude or ChatGPT. All collaboration occurs via an encrypted blind relay that does not access user data. The project is MIT licensed and available on GitHub, built using reveal.js and other libraries.
