# Futur3 Board > A browser app for node-based visual boards (ideas, notes, lists, to-dos, tables, images, links, code, colours, sub-boards, frames and connectors). Boards are JSON files kept in the user's own Google Drive or local folder; this site stores nothing. AI assistants: read the skill below before creating or editing boards for a user. It documents the board file format (version 2), how users import a file (File > Import > Board JSON file, or drag it onto the canvas), and the app's menus and shortcuts. ## Skill - [SKILL.md](/skill/futur3-board/SKILL.md): how to build boards and use the app - [example.json](/skill/futur3-board/example.json): a complete example board - [futur3-board.zip](/skill/futur3-board.zip): the skill packaged for upload to Claude (Settings > Capabilities > Skills) ## Pages - [App](/): sign in with Google (approved accounts only) - View-only boards: /view# (no sign-in, read-only)
