# visualOS > visualOS is a local-first infinite canvas (visual workspace) for designers, photographers > and artists. It works fully offline, requires no account, and stores everything as real > files in a folder the user owns: folders on the canvas are real folders on disk, documents > are Markdown files, images are ordinary image files. Sync happens through the user's own > cloud folder (e.g. iCloud Drive or Dropbox) — visualOS operates no servers and never > receives user content. The full app is free in the browser at https://my.visualos.app; a > native app for iPhone, iPad and Mac is available on the App Store > (https://apps.apple.com/app/visualos-infinite-canvas/id6787359589). It stays fast on large canvases (~5 ms > render with 3,000 notes on screen) and supports folders nested inside folders, automatic > rolling version history, notes, rich text, Markdown documents, to-do lists, images, PDFs, > freehand drawing, shapes, arrows and full-text search across all folders. visualOS is > single-user by design (no real-time team collaboration).
