About usFrequently Asked Questions
Everything you need to know about AI Test Lab
What tests does AI Test Lab offer? ▼
AI Test Lab offers 4 free tools: 1) Personality Type Test - a 40-question Likert self-report 16-type questionnaire, 2) AI Life Summary - a birthday-hash entertainment summary, 3) AI Age Calculator - fixed-offset age comparison for entertainment, 4) AI Compatibility Test - a fixed-weight comparison of two people’s Likert answers. All tools are available in 5 languages.
Are the tests free? ▼
Yes, all tests on AI Test Lab are 100% free. No signup required - just enter your birthday and get instant results. You can also download results as images or share them on social media at no cost.
How does the compatibility test work? ▼
Two people answer short Likert questions, and fixed weights are applied to the answer differences to produce a playful compatibility score and a per-question agreement breakdown. Optional birthday labels are for fun; this is not a relationship assessment.
How is the playful Mental Age score calculated? ▼
The age calculator uses your inputs and lifestyle questions to generate a playful age comparison. It is not a medical, psychological, or real-age measurement.
Can I share my test results with friends? ▼
Compatibility, Soul Type and Mental Age results download as an image (Story 9:16 / Square 1:1). The Personality Type test saves a result card image. Available channels vary by test — LINE, X (Twitter), Facebook and copy-link are supported. Send one to a friend and compare.

AI Test Lab is perfect for anyone curious about themselves! Whether you're looking for fun party games, wanting to test compatibility with your partner, or simply curious about your personality traits.
