Overview
Deep Personality is a science-backed personality assessment platform that integrates approximately 28 research-supported assessments into a single, unified experience. Completing the full battery typically takes under an hour, and the results are compiled into a 50+ page AI-generated report that explains not just what your scores mean, but how every dimension connects across personality, mental health, and relational patterns.
The platform covers a notably wide range of psychological frameworks. Personality trait scoring includes Big Five, HEXACO, and PID-5-SF; relationship and self-awareness dimensions include Attachment Style and Dark Triad indicators (Narcissism, Machiavellianism, Psychopathy); and the app also incorporates validated mental health screening instruments — including GAD-7 (anxiety), PHQ-9 (depression), ACE (adverse childhood experiences), PCL-5 (trauma), and eating disorder and substance use screenings — each accompanied by appropriate crisis resources where needed. Rather than handing users a score sheet, Deep Personality synthesizes these dimensions into one cohesive written narrative.
The result is a genuinely deep self-portrait — and a shareable one. Users can invite a partner, friend, or colleague to complete their own assessments and then view a compatibility report that maps alignment, complementary strengths, and potential friction points. Deep Personality is a consumer information product designed for personal reflection and self-awareness; it is not a clinical diagnostic tool or a substitute for professional mental health care.
Key Features
~28 research-supported assessments in one session — The full battery covers personality trait scoring (Big Five, HEXACO, PID-5-SF), Dark Triad indicators, Attachment Style, and multiple validated mental health screening instruments (GAD-7, PHQ-9, ACE, PCL-5, and others). All assessments are completed within a single session, typically under an hour.
50+ page AI-generated personality report — Rather than handing you a score sheet, Deep Personality produces a long-form written analysis — reportedly 50+ pages — that contextualizes your results, explains their real-world implications, and connects patterns across personality, mental health, and relational dimensions. Something no single-framework tool can match.
Multi-framework personality trait scoring — Results include Big Five traits, HEXACO dimensions, and PID-5-SF (a clinically-used personality inventory), giving users a more granular and research-grounded picture of their traits than MBTI-style typologies alone.
Partner and friend comparison — Users generate a shareable invite code, allowing any connection to complete the same assessments and then unlock a compatibility report that maps alignment, complementary strengths, and potential friction points across all dimensions.
AI assistant prompt output — After completing assessments, users receive a customized prompt they can paste into any large language model to create an AI assistant that genuinely understands their personality — a practical bridge between self-knowledge and everyday AI use.
Downloadable PDF report — Full assessment results can be exported as a PDF for offline access, journaling, or sharing with a coach or therapist.

FAQ
Is Deep Personality free to use?
Deep Personality has a free tier that lets you start assessments without a credit card. However, the full 50+ page AI report and partner comparison features are available as paid one-time purchases (~$19 for the full report; ~$29 for the comparison plan, with discounts offered periodically). An email address is required to create an account and save your results.
How long does the assessment take?
The full assessment battery — approximately 28 assessments — is typically completed in under an hour. All assessments are completed sequentially within a single session without leaving the platform.
Which personality frameworks does Deep Personality use?
Based on the platform's official privacy policy, confirmed assessment dimensions include: Big Five, HEXACO, and PID-5-SF (personality trait scoring); Dark Triad indicators (Narcissism, Machiavellianism, Psychopathy); Attachment Style; and validated mental health screening instruments including GAD-7 (anxiety), PHQ-9 (depression), ACE (adverse childhood experiences), PCL-5 (trauma), plus eating disorder and substance use screenings. The full list of ~28 assessments may include additional dimensions not listed publicly.
How does the partner comparison feature work?
After completing your own assessment, you receive a unique invite code. Share this code with a partner, friend, or colleague. Once they complete their own assessments, a compatibility report becomes available that maps where you align, where your differences complement each other, and where potential conflicts may arise.
Is my data private and secure?
Deep Personality uses email-based authentication and stores data securely via Supabase with row-level security, encryption at rest, and TLS in transit. The platform does not sell, rent, or trade personal data. Sharing is only triggered when you actively create a share link. Assessment data — which includes sensitive psychological and mental health information — is covered by additional safeguards under PIPEDA (Canadian privacy law). For full details, see the official Privacy Policy.
What is the AI assistant prompt feature?
After completing all assessments, users receive a specially crafted prompt that summarizes their full personality profile in a format optimized for large language models. Pasting this into ChatGPT, Claude, or another AI chatbot effectively creates a personalized assistant that understands your communication style, values, and behavioral tendencies.
Is Deep Personality a clinical or diagnostic tool?
No. Deep Personality is explicitly a consumer information product — similar in nature to fitness trackers or genetic ancestry services — and is not a psychological service, clinical assessment, or treatment tool. The AI-generated analyses are produced "as-is" and have not been reviewed or endorsed by licensed mental health professionals. Results should be used for personal reflection only. If you have mental health concerns, please consult a qualified healthcare provider.
Can I retake the assessment?
Yes. The platform includes a "Reset Progress" option that allows users to start the assessment from scratch. This is useful for tracking how your responses may shift over time due to major life changes.
Is there a mobile app?
As of launch, Deep Personality is a web-based platform only. No dedicated iOS or Android app has been announced, though the site is accessible via mobile browser.
Why isn't Deep Personality available in the EU?
Deep Personality is officially available in Canada and the United States only. Residents of the European Union, European Economic Area, and United Kingdom are geo-blocked from accessing the service, and the platform explicitly states it does not process personal data of EU/EEA/UK residents. The Terms of Service note that attempting to bypass this restriction via VPN or proxy constitutes a violation of the terms and may result in account termination. There is no official timeline for an EU launch at the time of writing.
How is Deep Personality different from free tests like 16Personalities or Crystal?
Most free personality tools focus on a single framework (typically MBTI-inspired or Big Five alone) and provide brief summaries. Deep Personality integrates approximately 28 assessments in one session and generates a 50+ page interconnected analysis — making it significantly more comprehensive than single-test alternatives or AI coaching tools that offer only surface-level trait descriptions. For users who also want AI-powered conversational support alongside their insights, ChatPal is a complementary option worth exploring.
