Everyone keeps telling you to use AI. Maybe one of them has clicked for you. Maybe none of them have. Either way, the AI that actually fits you may not be the one you're using. The APMI™ (Adaptive Personality Match Index) is a personality test that finds the AI that fits how you think and work.
There are dozens of AI models out there. We tested ten of the most-used. They feel different from each other, and they feel different to different people. APMI is the system that figures out which one fits you.
We built two tests that share the same four dimensions but ask different things on each side. The AI test measures personality plus style. Your test measures personality plus preferences.
On the AI side, we don't ask the AI what it's like. We put it under pressure and watch. Does it admit when it doesn't know? Does it hold its ground when challenged? Does it make things up when it's stuck? Your quiz measures how you actually think and work, in the same dimensional space.
Both tests land on the same four letters, which is what makes the match a direct comparison rather than a translation.
The AI you'll actually want to use, every day.
Ten of the most-used AI models. Each one tested behaviorally on the same four dimensions your quiz maps you to.

APMI is the result of months of behavioral testing across the full panel of ten AI models, paired with iterative development of a matched human instrument. The framework, the instruments, the candor layer, and the matching architecture are documented in full in an open-access paper.
To our knowledge, no one else has built a matching system that types both humans and AIs on the same dimensions and compares them directly. Most AI evaluation today is capability benchmarking, what an AI can do. APMI measures the other axis: how it does it, and which user that fits.
Your match is the output of that work. Take ten minutes with the quiz and you'll have an answer you can act on with confidence.
