Rhizo is a calm, tactile space for ideas that are still taking shape. Write a thought. Move it where it belongs. Connect it to whatever it changes. No rigid templates. No forced hierarchy. Just a simple canvas that helps you see what you are thinking. In a few minutes, you can turn scattered thoughts into a working structure you can return to, expand, and act on. Every interaction is designed to stay out of the way: • Press to create a new block • Drag ideas into place • Double-tap to write • Connect related thoughts directly on the canvas • Add text and images when an idea needs more context The result is a clearer workspace with less mental overhead. Instead of keeping open questions, references, decisions, and next steps in your head, keep them visible on the canvas. That means fewer context switches and less time reconstructing what you meant. Rhizo is built for relationships that do not fit neatly into a tree: • One idea can connect to multiple parent ideas • Several ideas can share the same child • Cross-connections stay visible • Your structure remains a flexible network Most mind-mapping tools are designed to produce a finished diagram. Rhizo is designed for thinking while the idea is still changing. The canvas moves with you. Gentle motion and responsive feedback make each action feel direct without distracting you from the work. When your structure is ready, export it as editable JSON with stable IDs, text, positions, and relationships. Open the file in the AI assistant you already use. Ask it to expand, reorganize, summarize, or challenge your thinking. Then import the updated JSON back into Rhizo without flattening the structure. Your AI workflow stays connected to the original board. Use Rhizo for: • Game design • Product planning • Study notes • Research • Writing • Project breakdowns • Brainstorming • Visual thinking Start with one question: “What are you working on?” Then keep building from there. Your content stays on your device. Rhizo supports iPhone, iPad

visualOS is an infinite canvas for people who think visually. It is an infinite canvas for notes, folders, 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 or Dropbox 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. There is no server to reach, so there is no spinner, no sync wheel, no login wall. 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 • 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 • 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.
