Product prediction and planning

Athanor's AI works on the canvas while you draw. It needs an arbastro account: signed out, the AI features stay off.

Predict products as you draw

1. Draw the reactants and a reaction arrow after them (see Draw a reaction).
2. A box appears after the arrow with the predicted major and minor products, and how confident the prediction is.

Prediction is on by default when you are signed in. To turn it off, press Ctrl+K, open AI settings…, and switch off Predict products as I draw. Your choice is kept.

Plan a synthesis

Draw a retrosynthetic arrow from a target molecule, or select it and run Main menu › Object › Chemistry › Plan synthesis….

• Athanor streams complete multi-step routes back to buyable starting materials while you watch, ranked by the number of steps and how easy the materials are to buy.
• Approve or reject each route, and exclude reagent classes you do not want.
• Every compound along a route shows its sourced hazards.

Safety screening

Every structure and route the AI suggests is checked against the Chemical Weapons Convention schedules and the Australia Group precursor list. The check runs both in the app and on the server, and purchasing links are hidden for controlled compounds.

Predictions are labeled

A prediction always says it is a prediction, with how confident it is. It is never shown as a measured or published result.
