MyBias is a free, fan-made web app that pairs a 16-question MBTI personality quiz with a curated database of 580 K-pop idols across 90 groups. No affiliation with any K-pop agency.
Idol MBTI types, blood types, and nationalities are sourced from publicly reported results — interviews, variety show appearances, official agency profiles, and fan-verified databases such as KProfiles and kpop.fandom.com. We do not administer tests to idols ourselves.
All data reflects publicly reported results as of 2026. Idols can retake the MBTI test and get different results, so types may change over time. Blood type and nationality are factual and stable. We update our database when reliable new information becomes available. This is for fun and fandom — not a scientific assessment.
Each idol profile includes 14 fields: stage name, group, MBTI type, role/position, birthday, zodiac sign (computed), age (computed), agency, debut year, generation, blood type, nationality, and height. Portrait photos are sourced separately. No personal or sensitive information is stored.
Idol photos are sourced from kpop.fandom.com (via og:image extraction) and resized to 400x400 WebP for performance. Photos are property of respective agencies and used here for identification purposes under fair use.
MyBias is built on genuinely free APIs with graceful fallbacks. The MBTI quiz, idol database, all interactive tools, and the dataset download are 100% free with no signup required. We keep the lights on through ads. No paywall, no premium tier, no hidden costs.
The full dataset (580 idols, 14 fields) is available as JSON and CSV download under CC BY 4.0 for researchers, bloggers, and fan projects.
Minor protection: Idols under 18 are identified and excluded from any first-person persona or romantic AI features. All AI-generated content about minors uses safe, third-person framing only.
No impersonation: AI features generate fun, fan-oriented content. They do not impersonate real idols or simulate personal relationships.
Privacy: Quiz results and preferences are stored locally in your browser. No account required. We do not collect personal data beyond what is needed for analytics and push notifications (both opt-in). See our privacy policy.
K-pop focused. Unlike general personality databases that cover all celebrities, MyBias is built specifically for K-pop. Every feature, every page, every insight is designed for fans.
Interactive, not just data. Most databases show you a list. MyBias gives you a 2-minute quiz, bias battles with Elo rankings, a tier list maker, a guess-the-idol game, daily polls, and more.
Real photos. 580 idol photos at 100% coverage. Most personality databases have zero images.
Computed insights. Quick Facts on every idol page (group context, age rank, type rarity). Personality Dynamics on every group page. Member Chemistry scores. Content you cannot get anywhere else.
Free dataset download. The full database is available as JSON and CSV under CC BY 4.0. No other K-pop personality site offers this.
No signup required. Quiz results, games, and tools all work without an account. Your data stays on your device.
