# Futur3 Board > A browser app for node-based visual boards (ideas, notes, lists, to-dos, accordions, tables, images, links, code, colours, documents, drawings, titles, highlights, sub-boards, files and frames, joined by connectors), with presentations: camera views, a timeline and animations. Boards are .f3bd files (JSON inside) kept in the user's own Google Drive or a folder on their computer; the site stores none of them. AI assistants: read the skill below before creating or editing boards for a user. It documents the board file format (version 2), including presentations (board.present), how users import a file (File > Import > Board file (.f3bd), or drag it onto the board; .json also works), and how to use the app. App: https://board.futur3.app (Google sign-in, approved accounts only during the beta).
