Kangji
Snap a photo of
your lab report.
AI explains it in plain words.
Kangji reads your health checkup or blood test, pulls out what matters, and tells you what it means — in the language your phone already speaks. Then it stays around to answer your questions.
Everything about a report,
without the medical jargon.
Kangji is built around one idea: understanding a lab report shouldn't require a medical degree.
AI report reading
Photograph a printed or digital report. AI recognizes the hospital, date, doctor, and every lab value automatically — no typing.
4-dimension deep analysis
Overview, things to watch, improvement ideas, and follow-up suggestions — generated from your actual results, in careful, non-alarmist language.
Ask follow-up questions
Not sure what "LDL cholesterol" means for you? Just ask. Kangji answers grounded in your own report, and reminds you to consult a doctor for anything serious.
Medication reminders
Register your medications once — Kangji reminds you at the right time and tracks how consistently you've kept up.
Private by design
Your reports and photos are encrypted and stay on your device. They're only ever sent transiently for AI analysis — never stored on our servers.
Speaks your language
The interface and every AI-generated summary automatically follow your device's language — English, Japanese, or Chinese.
From photo to plain-language answer in seconds.
Take a photo
Snap or upload a photo of any lab report or health checkup summary.
AI reads it
Hospital, date, and every lab value are recognized and organized automatically.
Get a plain summary
A short, jargon-free explanation of what the report shows and what deserves attention.
Ask anything
Chat with Kangji about your results whenever a question comes up.
Real numbers, explained — not just repeated.
Every lab value is compared against reference ranges and flagged in plain terms, with trend graphs across visits so changes over time are easy to see.

- Informational only — never a diagnosis, always suggests seeing a doctor
- Works for checkups, blood panels, urinalysis, and more

Good questions.
Are my report photos uploaded anywhere?
No. Your reports and photos are encrypted and stored only on your device. When you run an AI analysis, the image is sent transiently to our AI provider for processing and is never stored afterward — not by Kangji, not by anyone else.
Is this a medical diagnosis?
No. Kangji's AI analysis is for personal reference only, not a substitute for professional medical advice. It's written to avoid alarming language and always encourages you to follow up with a doctor for anything that needs attention.
Do I need to create an account?
No — Kangji works fully without signing in. If you'd like your data to follow you across devices, you can optionally sign in with Apple or Google at any time.
What languages does Kangji support?
The app interface and every AI-generated summary automatically match your device's language: English, Japanese, Simplified Chinese, and Traditional Chinese.
Where do the reference ranges come from?
Lab value ranges and general health information are sourced from established medical references including the World Health Organization, MedlinePlus, the American Diabetes Association, and Mayo Clinic. Sources are listed in the app under Settings.
What happens if I run out of free analyses?
You can keep using everything else in the app — chat, medication reminders, your saved reports. To run new AI analyses, you can buy a one-time credit pack whenever you actually need one; nothing auto-renews.
Is Android coming?
Not yet. Kangji started on iPhone and iPad first so we could get the experience right before expanding.
