How Cira Works
Talk. Scan. Understand
your next step.
Cira is an AI nurse who listens to your story, looks at your vitals through a short face scan, and helps you decide whether to watch, see a doctor, or act quickly.
Talk
Share what's going on, in your own words.
Scan
A short face scan reads your real-time vitals.
Next step
Clear guidance — and a doctor when needed.
Step 1 — Conversation
Start with a real conversation.
You just talk. Symptoms, history, medications, worries, the goals you care about. No strange forms or rigid checklists — Cira asks the right follow-ups, the way a calm, patient nurse would.
- Speak in your own words, at your own pace.
- No account needed to begin a conversation.
- Cira listens for nuance, not keywords.
- Built on Claude-class medical reasoning, trained over billions of clinical data points.

Listening
Hi — I'm Cira. Tell me what's been going on today, in your own words.
Thank you for sharing. Is this new, or has it been changing slowly?

Step 2 — Face scan
Add real signals from your body.
Powered by Shen AI, your device camera reads subtle changes in skin tone to estimate vital signs — in about 30 seconds, with nothing to wear or attach.
Private by design. Cira uses the scan to calculate vitals. Raw face video is not stored — image frames are deleted after processing.
Step 3 — Understanding
Conversation + vitals = a clearer picture.
Cira combines what you said with what the scan measured, checks the patterns against medical knowledge, and gently explains what it likely means — and what to do next.
Watch at home
Patterns look reassuring. Cira suggests what to monitor and when to check in again.
Book a doctor visit
Something worth a closer look. Cira helps you find a doctor and prepares your summary.
Seek urgent care
Signals suggest you shouldn't wait. Cira gives clear, calm steps to get help right now.
Step 4 — Real doctors
When you need a human doctor, we don't leave you alone.
Through our partnership with Air Doctor, Cira connects you to a network of 20,000 doctors across 180 countries. Your Cira summary travels with you as a hand-off to whichever doctor you choose.
- Cira is not the doctor — Air Doctor handles the visit and the network.
- Use your Cira report to skip repeating the basics.
- Find local, in-language care wherever you are.

Comparison
How Cira differs from chatbots and AI doctors.
Cira isn't trying to replace your doctor — and it isn't a generic chatbot either. It sits in the gap between the two.
