WHY IT MATTERS

While office documents have moved behind cloud logins, Bento takes the other path. The deck, fonts, images, charts and the full editor travel in one .bento.html file, and on save the file rewrites its own data block (File System Access API, with a download fallback). The document sits as readable JSON near the top of the file, so an AI agent or any other tool can edit it in place.

BUILD FROM THIS

Ship a company template as a .bento.html file that colleagues can edit and present with nothing installed, or write a script that generates decks from data because the document is plain JSON.

WHO IT'S FOR

Small teams that trade decks often: share slides the other side can open without installing anything
Developers driving documents with AI agents: generate slides by editing the JSON block
Individuals avoiding cloud subscriptions: presentations that stay as a local file

START IN 5 MINUTES

# 1. Open https://bento.page/slides in a browser (the whole app, running on a starter deck)
# 2. Or download the file: https://bento.page/releases/slides/Bento_Slides.bento.html (~560 KB per the README, ~710 KB per the site; no account, no installer)
# Build from source (Node 20+):
# cd slides
# npm install
# npm run build:single   # → dist-single/Bento_Slides.bento.html (the product)

CAVEATS

MIT licence (bundled reveal.js, Moveable and Selecto are MIT; typefaces OFL). Editing is desktop-first; phones are for viewing and presenting, per the README. Known trade-off: undo during live collaboration is snapshot-based and can revert a collaborator's concurrent edit to the same property; the sync relay is optional. Free.
