A voice-first health AI companion

Your research partner for the diagnosis nobody's found (yet)

Coco helps you run experiments and spot patterns so "figuring it out myself" doesn't mean doing it alone

Start your first experiment

AI built with care

Coco is part-companion, part-care team—with unlimited time and attention for your health

Get started with Coco

Symptom tracking that's effortless

Traditional symptom trackers are too rigid. Coco can listen to a quick verbal and automatically logs symptoms and insights on your behalf.

AI that proactively plans and reaches out

Unlike other AI companions, Coco works for you in the background and also identifies the right moments to reach out and engage as well

Coco's Plan for Today

One experiment at a time

Coco helps you track one change at a time so you can actually tell what's connected to feeling better.

Start an experiment now

*Coco is not a doctor. Always talk with a qualified clinician before changing medications, supplements, or care plans.

Appointment prep made easy

15 minute appointments don't leave room to explain months of symptoms. Coco automatically turns your experience into an easy-to-share report.

What users are saying about Coco

First time in three years I've walked into an appointment with actual data instead of a foggy memory.

Maya Z.

I finally have proof it's not 'just stress.' That alone was worth it.

Daniel P.

First AI I enjoy talking to!

Coco doesn't ask me to explain myself. She just listens and figures out the pattern.

Ethan M.

My rheumatologist actually said the health record Coco write for me was very useful. First time a doctor said that about anything I brought in.

Steven L.

Logging by voice is the reason I didn't quit. Typing on a flare day was never going to happen.

Kevin Brooks

Fitness Coach

Found out my flares follow bad sleep by two days. Three years of guessing, answered in six weeks.

Hannah L.

I love that Coco syncs with my Apple Watch so half the tracking happens without me touching my phone.

Priya S.

Coco is the first app for symptom tracking that I didn't abandon. The voice check-ins just take 30 seconds so I actually keep doing them.
