visualOS is an infinite canvas for people who think visually — for moodboards, notes, images, to-do’s and sketches. It works fully offline and saves to real files in a folder on your device. YOUR DATA IS A FOLDER YOU CAN OPEN Connect any folder on your disk and visualOS mirrors your canvas into it — every folder on the canvas is a real folder, every document a Markdown file, every image an image. Put the folder in iCloud Drive and it syncs through your cloud, not ours. If you ever leave, everything stays readable. Forever. OFFLINE ISN'T A MODE. IT'S THE ARCHITECTURE. On a flight, on the train, in a studio with no signal — visualOS doesn’t care. Your work doesn’t live on our servers, so there is no sync wheel, no forced login. Your canvas opens instantly because everything is already here. BOARDS WITHIN BOARDS Any board can hold more boards. A project becomes a world: moodboards inside client boards inside your studio. Drag elements into a board to file them away; breadcrumbs keep you oriented; a double-tap takes you deeper. NO ACCOUNT. NO SUBSCRIPTION. Open it and work. There's nothing to sign up for, nothing to verify, nothing to cancel. Pay once and it's yours forever — one purchase unlocks every Apple device. FREE IN THE BROWSER, BUT THE APP GOES FURTHER Try visualOS free in your browser at visualos.app. When you're ready for it everywhere, the app adds what a browser can't: true offline access on the train or a plane, native pan-and-zoom gestures, Apple Pencil drawing, and your boards saved as real files that sync across iPhone, iPad and Mac through your own iCloud. EVERYTHING ELSE • Grids that line up your cards in columns and rows • Frames for print, PDFs and social media formats • Mindmaps with three layouts • Remove a picture’s background in one tap, right on your device • Notes & rich text • Long-form documents stored as plain Markdown • Interactive to-do lists on the canvas • Images & PDFs — drag, paste or drop them in • Freehand drawing • Magnetic arrows that snap and bend • Search every board at once • Export as JPG, PNG or PDF, or print • Groups, locking and a snap grid Your ideas. Your files. ABOUT US As creatives, we’ve always relied on visual canvas tools to organize our thoughts, plan projects, and make sense of ideas. But one thing kept bothering us: our files and knowledge were always tied to cloud-based services. We wanted the freedom to access everything offline, without worrying about losing our work or giving up our privacy. So why can’t our own files on our device be visualized in the same intuitive way? And that’s how the idea for visualOS was born: a visual representation of your internal folder structure — offline, private, and secure. Your data stays on your device, where it belongs. We’re Sarah and Gerald, a husband-and-wife team who have been living, loving, and building things together for more than 20 years. Creating visualOS has been a ton of fun and thanks to AI we were able to push it further than we initially imagined. Now we’d love to hear what you think. If visualOS helps you work a little more creatively or makes your files easier to navigate, we’d be grateful if you shared it with others.
