OkSo is for visual thinkers, students, and anyone who wants to sketch an idea instead of explaining it only in words. Use its uncluttered online canvas to make visual notes, brainstorm, map out plans, or explain concepts such as algorithms and system designs. The canvas has room to expand, and you can add freehand drawings, text, and shapes, then edit them with undo and redo, copy, paste, and resize tools. Organize related sketches as nested pages: add links to subpages within a drawing and move between levels to keep complex topics organized. Your drawings are stored in your browser, and you can export them to files to move them between devices manually. OkSo is also available as an installable progressive web app.
