What the AI assistant sends, and where
Your question, the earlier messages, a description of the page and any image you attach go to the provider shown under the assistant box. Signed out, Athanor sends nothing to any AI provider.
The assistant works only while you are signed in. Signed out, Athanor sends nothing to any AI provider. The name under the assistant's box is the provider your requests go to.
What goes with a request
- What you type, and the earlier messages in that conversation.
- A description of the page you have open: its structures (as SMILES, with positions), notes, your selection and the document name.
- Images you attach to a question.
Where it goes
- arbastro Intelligence, the default: requests go to arbastro's AI service, which passes them to Anthropic and sends the answer back. arbastro does not store what you send or what comes back, only a monthly count of requests, tokens and credits for your plan's allowance. Anthropic's commercial terms do not allow it to train on your data.
- Your own key: requests go directly from your device to the provider you chose, not through arbastro. Athanor tells you before your first message to each provider.
Predicting products as you draw
When Predict products as I draw is on (the default while signed in), finishing a reaction sends its structures and conditions to predict the products. Turn it off in AI settings.
The full detail, including voice mode, is in section 5 of the privacy policy.
