A voice, not a wall of text.

Every answer is fully spoken, thorough and unhurried, in step with the drawing. The figure appears exactly when the explanation needs it, timed to the motion.

Drawn for your question, never retrieved.

Jentoo writes real code for your exact question and a sandboxed engine executes it. Every curve, label, and arrow is derived and measured into place — nothing is picked from a template library.

From raindrops to DNA.

Biology, physics, economics, engineering, and everything that isn't a school subject at all. If you can ask it, Jentoo can draw it. New question, new figure, every time.

Positions aren’t guessed. They’re derived.

This curve is 20,000 computed points, no keyframes, no artist. Every Jentoo figure is built the same way: each label, arrow, and curve derived from the same equations, coherent by construction.

Every subject. And everything that isn't.

There is no template library to run out of. Tap any of these, and each one becomes a live, drawn answer.
