About this tool
Blood type personality is a beloved pastime in Korea and Japan, where people often ask each other about their blood type the way others ask about zodiac signs.
This tool covers all ten pairings of A, B, O and AB, regardless of gender.
For each pair you get a chemistry percentage, a short summary, the common images people associate with each blood type, what tends to work well, what to be kind about and a date idea.
Every result is written in a warm, positive tone. Please remember that blood type personality theory has no scientific basis, so treat this purely as light entertainment and a conversation starter.
It is not a prediction about your relationship and does not replace professional advice. Everything runs in your browser, and nothing you choose is saved or sent.
How to use
- Tap the blood type of each person.
- See the compatibility percentage, strengths, kind reminders and a date idea.
- Share the result and tag your friend or partner to try theirs.
