Rapid validation of AI features for a healthcare scribe

Turi Saúde is an early-stage healthcare startup on a mission to give physicians back their time — by taking the paperwork off their plate.

USER PAIN POINT

47% of physicians’ time is spent on admin workflow instead of patient care

Surveyed Geriatrician

“It would be very helpful to compile the exams and easily paste this information into the medical record. [...] instead of typing each exam one by one, I can use that time with the patient.”

Interviewed Radiologist

“During the appointment, they bring everything printed. So I take pictures and write things down later, otherwise I lose too much time.”

Challenge

Turi's AI scribe streamlines documentation, but only partially addresses the full user need.

Our goal is to build a complete workflow solution so clinicians spend less time on paperwork and more time with patients.

My role

Owned the full product build and launch of Lab, Turi's experimentation platform. Worked closely with the Founder and Engineer to ship validated features into production.

hypothesis

If clinicians receive a summary of all patient lab and imaging results written exactly as they document in the EHR, they will save time on admin work and be able to focus on patient care.

The feature synthesizes multi-page files into a summary, ready to paste into the EHR.

User interviews revealed:

✅ Strong perceived value by users
Reduced patient anxiety during consultations
⚠️ Improvements needed with OCR model and output experience

The LME form is a mandatory document for approving high-cost medications, with strict completion requirements. Filling errors rank as the third leading cause of deferrals, delaying treatment for millions of patients.

User interviews revealed:

✅ Strong interest by B2B partners
✅ Positive social impact
✅ Not offered by competitors
⚠️ Partial solution (21%) → 100%
