Bento Slides

Bento Slides is an open-source slide tool. Its defining idea is that the entire application — viewer, presenter and editor — plus your document all live in a single .bento.html file: open the file in any browser to edit, present and share; on save it rewrites itself. On LazyCat Box: open .bento.html files directly from the drive via "open with Bento", edit them, and save back to the drive. The editor keeps element morph transitions, built-in charts, end-to-end-encrypted live collaboration, and an AI-friendly document API (the document is plain JSON, easy to generate and modify programmatically).
