πŸ”’ HOW SAVING WORKS: This app saves your work automatically β€” but ONLY inside this browser, on this device. Nothing is saved on our website or anywhere on the internet. If this browser crashes or closes, just come back to this page and your work will be here. BUT if you clear your browser’s cache, cookies or site data, your saved work is gone forever. To keep a permanent copy, download/export your work to your computer using this app’s export buttons.
How to Use

Add a shape from the Shapes row, tap it to select it, then drag it into place and edit its text and colours in the panel that appears. Turn on Connect, then tap two shapes to link them with an arrow β€” moving a shape moves its arrows too. Tap a link to delete it, and use Undo if you change your mind. Export saves a PNG image or an SVG file, and Print / PDF prints only your diagram on a clean page.
