Animate ChemDraw (.cdxml) line art as rotations and bond formations, using the styles and colors of your choice.
It follows the drawing rather than a model of the molecule, so what comes out looks like what you drew.
An arrow means one structure becoming another; an equivalency sign means the same molecule redrawn another way, which turns rather than morphs. Both play in one clip.
Place a copy carrying 3D coordinates above the drawing you want animated and it supplies the axis and angle. That copy is never drawn — your own drawing moves.
Bonds keep their width, letters stay readable, and the white gaps where bonds cross are recomputed as things move rather than baked in.
Solid and hashed wedges, formal charges, stacked labels, subscripts and colours come out as you drew them.
When the automatic pairing isn't what you meant, click an atom on the left and its partner on the right. Bonds that break turn red, bonds that form turn green.
Choose the length, frame rate and pixel width; get an animated GIF, an MP4, or a numbered sequence of frames for a figure.
Order and intent come from the drawing itself — no configuration file needed for the common cases.
One structure becomes the next. Atoms travel, bonds break and form, labels dissolve where a group changes.
The same molecule, drawn another way. It turns about the axis the two drawings imply instead of morphing between them.
Sitting above your drawing, a roughly oriented cif can help the program understand how your structure moves through 3D space.
Four steps, and nothing to configure for a first look.
The first render takes a minute to get going, because your browser is downloading Python and the scientific libraries; it keeps them afterwards. If you would rather work offline, or need MP4, use the download — on a Mac its first launch needs right-click → Open, once only.
