How your material is handled

Transient inference, not retained

Conversations are processed transiently to produce a response and are not retained by the service afterward.

Saved notes encrypted with keys only you hold

Anything you choose to keep is encrypted with keys that stay with you. We do not hold a copy of them.

Confidential-computing GPU routing

When cloud serving starts, Professional requests route only to confidential-computing (TEE) GPU capacity.

Internally tested, not independently audited.

Read what that means and what is in the documentation pack on the Security page.

Who it is for

Solo and small-practice professionals with a confidentiality duty and no IT department.

• Legal — family, immigration, and small-firm practice
• Clinical — therapists and coaches who draft notes
• Financial — independent advisors and planners
• Journalism — investigative and independent reporters
• HR — consultants handling personnel matters

A monthly call

Thirty minutes each month with the people building the product, to shape what ships.
