Biology diagram labeller
The AI diagram labeller labels plain diagrams, and covers labels that are already printed. In Has Labels mode the four printed labels on this cell diagram are found for you and covered with letters, ready for recall.
A hand-built replica of the real builder page, not a screenshot. Every control shown exists in the product.
This tool in other subjects, Physics and Chemistry.
Why this works in Biology
The demo shows an animal cell with its four labels found and covered. The class names what sits under each letter, and the style controls set the marker style, fill and size so the covers read from the back of the room.
The covered diagram does not stop here. Send it to Stimulus Questions and the generated questions reference the letters rather than naming the organelles, or send it to Memorise and Recall for a timed show, cover, check routine. Both pages are in the resource cards below, built from this exact diagram.
