Two letters the 16 types leave out, Emotional Stability and Honesty-Humility, make 64 types (e.g. INTJ-CM). Borderline scores are flagged, life-area pages cite research, and compatibility has no fake %. Free, ~8 min, no signup, in 33 languages. Optional $14.99 Deep Report.

Partial The quiz and scoring UI are easy to build, but credible percentile norms depend on a proprietary dataset of 40,000+ respondents that a solo builder cannot replicate.
What it would actually take: The front end is a standard quiz with IPIP-style items and a scoring engine. The hard part is the norm tables, which need a large, representative sample collected with ethical consent and validated psychometrically. Building a real version requires access to comparable respondent data or a psychometrics background to derive and validate norms.
