Bento Releases AI Agent Presentation Tool

Bento is an open-source presentation tool that bundles document data, an editor, a viewer, and presentation mode into a single .bento.html file. Opening the file in a browser for editing updates the internal plain-text JSON data block, allowing document sharing without separate installations or service accounts.

Since the file structure is based on plain-text JSON, AI agents with file system access such as Claude Code, Cursor, and Aider can directly modify slides without plugins or separate APIs. Chatbots without file access can be used by copying the document JSON and pasting back the modified results.

• The compressed shell size is approximately 560KB.
• The document format and agent editing rules are published via docs/format.md and docs/agents.md.
• Supports morph presentations, charts, presenter view, PDF export, comments, and real-time collaboration.
• Collaboration uses AES-GCM encryption and a custom CRDT; in offline mode, data does not leave the device.
• Releases are signed with ECDSA, and the app suggests self-updates internally.

In Claude Code, it can be used by installing the bento-slides plugin; when combined with local models, the entire presentation editing process can be handled locally.
