Bento is a local-first presentation tool packaged as a single self-contained HTML file. Each deck carries its own viewer, presenter, editor, fonts, images, charts, animations, and document data. It opens in a modern browser without an account or installer and rewrites its own embedded data when saved. The document model remains readable as plain JSON, making files portable, inspectable, and directly editable by AI agents. Bento includes morph transitions, speaker view, comments, motion paths, PDF export, and built-in interactive charts. Optional collaboration uses end-to-end encryption and a CRDT so offline edits can merge while the relay stores only ciphertext. An offline mode blocks updates and collaboration, while signed self-updates create a new file and preserve the previous copy for rollback.
