Why two tests, not one

Different lens, complete picture.

MBTI tells you the structure. SBTI tells you the texture. Together they read like a personality x-ray + behind-the-scenes blooper reel.

  • "Hilarious — the silly label was so accurate even my mom recognized me. It also analyzed why I always argue with my ENTJ boss — screenshot, sent to her."

    INFP × Overthink, underdo

    ENTJ × Tough love

    "My boss gave me a raise after seeing my report. The 15-dim radar says more than my OKRs ever did."

    ISFP × 3am philosopher

    "Posted the radar chart and my feed exploded — three friends bought the ¥39.9 report just to see their own shape."

    INTJ × Grind with emotions

    "First test that dared to say 'you act like you don't care but you deeply do' — hit right in the gut, annoying but accurate."
FAQ

Common questions

Is it scientific?

Our MBTI track is based on the Big Five model (IPIP-NEO) with 99 validated Likert-scale items. The SBTI track is for fun — but still surprisingly accurate.

Do I have to pay?

You get a free preview with both types, match %, 15-dim radar, and short descriptions. Unlock full reports ($4.9 Mini / $19 Premium) and AI Coach ($9.9/month) when you're ready.

Can I take just one test?

Yes! Take MBTI (99 questions) or SBTI (99 questions) separately. The cross-comparison unlocks when you finish both.

Is my data safe?

We don't sell your data. Results are anonymized after 30 days. Read our privacy policy for details.
