Capabilities

Tools 3

calculate_personality_scores

Use this when the user has answered all 50 items of the IPIP Big-Five Factor Markers test (answers 1-5 in item order) and wants their personality test scores. Returns raw scores (10-50) for Extraversion, Agreeableness, Conscientiousness, Emotional Stability and Intellect/Imagination, an approximate percentile, a low/average/high band with a plain-language description, a share card (SVG) and a share page link. Reverse-keyed items are scored automatically. Does not diagnose anything and is not for hiring decisions. Do not use for other questionnaires (MBTI, DISC, Enneagram) or with invented answers.

Discovered
compare_personality_scores

Use this when the user wants to compare two people's Big Five personality test results, e.g. friends, partners or siblings who both took the 50-item test. Takes each person's five raw scores (10-50) and returns per-trait differences (similar when 3 points or fewer apart), each person's percentile, a comparison card (SVG) and a comparison page. Describes differences only; it does not rate compatibility, predict relationships, or judge who is better. Do not use for hiring or team selection.

Discovered
show_personality_test

Use this when the user wants to take a personality test, a Big Five (five-factor, OCEAN) test, or a personality test for self-reflection, students, teens or couples. Shows the 50 public-domain IPIP Big-Five Factor Marker items in an interactive widget (one at a time, progress bar, back button); answers stay in the widget until the user submits, then they are scored with calculate_personality_scores. Also returns the item list and a browser link to take the same test. Does not score anything by itself. Do not use for MBTI/16-type, DISC or Enneagram tests, or to screen job candidates.
