Deep Personality Alternatives

Deep Personality is a web-based assessment run by Deep Personality Inc., which its privacy policy says is based in British Columbia, Canada. The product is for adults. Here is how its own site describes it as of October 2026.

Format

You can start without an account or a credit card. The free entry point is a short quiz of ten items from the public-domain IPIP pool, two per Big Five trait. The site calls this a teaser: it gives a first read and an archetype, and it does not score attachment. The full assessment scores the IPIP-50 (ten items per trait, reported as five domain scores with percentiles) and then measures attachment style. The homepage and about page describe the complete battery as 28 research-backed instruments taking 35 to 50 minutes.

What it measures

Instruments named on its homepage and about page include:

• •Big Five personality (IPIP-50)
• •Attachment (ECR-R)
• •Anxiety (GAD-7) and mood (PHQ-9)
• •Stress response (PCL-5) and perceived stress (PSS-10)
• •Compulsive patterns (OCI-R)
• •ADHD (ASRS) and autism (AQ-10) screeners
• •Life satisfaction (SWLS) and career fit (RIASEC)
• •Self-esteem, coping, grit, mindfulness, optimism, need for cognition, empathy, emotional intelligence, locus of control, distress tolerance, perfectionism, and cognitive reflection

The site is direct that the clinical-style measures are screening tools that do not diagnose anything, and that the product as a whole is for personal self-reflection.

How results are delivered

The paid report is a written profile that the site describes as 10,000 words or more. Its public sample report, built on a fictional demo profile, shows 14 AI-generated chapters, including identity, personality, values and motivation, strengths and blind spots, working life, romantic compatibility, friendship, relationship patterns, and wellbeing. Its terms state that the interpretations are generated by AI language models. If two people both finish the full assessment, a partner comparison puts the two profiles side by side, and the about page says it highlights trait gaps and likely friction points.

Pricing

Its pricing page, last updated October 7, 2026, lists a free teaser, an Individual plan at $9.99 per month, a Comparison plan at $14.99 per month, one-year gifts at $29 (Individual) or $49 (Comparison), and lifetime access at $149 once. The same page notes that older third-party listings quoting a $19 or $29 one-time price are out of date.

Opinion DNA starts from a different question: why you think what you think. The assessment is 179 statements answered on an agree-disagree scale, which takes about 10 to 15 minutes. Your answers are scored into 48 continuous dimensions, each on a 0 to 100 scale and shown next to the population average, in three layers:

• •Personality (12): the Big Five, the Dark Triad (Machiavellianism, narcissism, psychopathy) measured as everyday trait continua, two emotion-regulation styles, mortality concern, and life satisfaction
• •Values (24): five moral foundations, seven cooperative virtues, ten personal values from Schwartz's model, plus social dominance and authoritarianism
• •Meta-Thinking (12): thinking-style measures such as dogmatism, need for cognition, intellectual humility, and intolerance for uncertainty, plus primal world beliefs about whether the world is safe, good, alive, and enticing

A few examples of how these read in practice. Your score on care next to your score on fairness says a lot about which moral arguments land with you and which leave you cold. Intellectual humility describes how readily you revise a view when the evidence turns. Self-direction shows how much you need to set your own course, and it reads differently depending on where you sit on conformity.

Once your scores are calculated, AI reads your specific combination and writes a personal report covering personality, values, meta-thinking, career, and relationships. The scores come from your answers; the AI's job is interpretation. Opinion DNA is a $47 one-time purchase with lifetime access and a 30-day money-back guarantee. It was built over three years with more than 60 experts from Oxford, Cambridge, NYU, Royal Holloway, and UPenn, using peer-reviewed psychometric scales. Our 48-dimension personality test page walks through every dimension, and the methodology page explains how the scoring works.

Where they overlap

Both score the Big Five on continuous scales instead of assigning a type. Both touch on life satisfaction, need for cognition, and personal values in some form. Both turn the scores into a long AI-written interpretation, and both offer a way to compare two people. If the Big Five is all you care about, either one will give you a usable read.

Where they differ

• •Clinical-style screening: Deep Personality runs screeners for anxiety, mood, stress response, compulsive patterns, ADHD, and autism, and reads them against your personality. Opinion DNA has no screeners, and its methodology page is explicit that it is not a clinical or diagnostic tool.
• •Attachment: attachment style is a core part of Deep Personality's full assessment. Opinion DNA does not measure attachment.
• •Values and moral reasoning: Opinion DNA gives values 24 of its 48 dimensions, including moral foundations such as loyalty and authority, cooperative virtues, and social orientation. Those three families are not among the instruments Deep Personality lists.
• •Thinking style and worldview: Opinion DNA's Meta-Thinking layer covers dogmatism, intolerance for uncertainty, and primal world beliefs such as whether you see the world as safe or dangerous. Deep Personality's list includes need for cognition and cognitive reflection; worldview beliefs do not appear on it.
• •Time and payment: Deep Personality's full assessment runs 35 to 50 minutes and is sold monthly or as a $149 lifetime plan. Opinion DNA takes 10 to 15 minutes and costs $47 once.

Neither product hands you a four-letter type, and neither claims to diagnose anything. The difference is mostly about which parts of you each one points its questions at.

Depending on what drew you to Deep Personality in the first place, one of these may fit better than either product above.

A free Big Five test

Deep Personality's Big Five scores come from the IPIP-50, a public-domain inventory, and free IPIP-based Big Five tests are widely available. If five trait scores are all you want, start there. Our Big Five alternatives page covers what a Big Five profile leaves out, such as values and thinking style.

Truity

Truity offers several separate free tests, including the Big Five, the Enneagram, DISC, and its type-based TypeFinder. It suits people who want to choose a framework rather than sit one long combined battery. The Opinion DNA vs Truity comparison goes into more detail.

VIA Character Strengths

The VIA survey is free and produces a profile of 24 character strengths. Its focus is on what you do well, which makes it a gentle companion to anything that includes screeners. See Opinion DNA vs VIA.

16Personalities

16Personalities is a free test of about 10 minutes built around personality types, with long free type descriptions. It sits at the other end from Deep Personality: quick, type-based, and easy to share. Our 16Personalities comparison explains the trade-offs of types against continuous scores.

If you searched for "deeper personality"

You may have meant Deeper Signals (deepersignals.com), a separate company that sells personality, values, and cognitive assessments to organizations and coaches for hiring and development. It is unrelated to both Deep Personality and Opinion DNA.

Deep Personality is probably the better fit if

• •you want attachment style measured alongside your personality
• •you are trying to tell whether a pattern looks more like anxiety, ADHD, or plain temperament, and you want validated screeners you can take to a professional
• •you want a long narrative report and a partner comparison, and 35 to 50 minutes is fine
• •a monthly plan or the lifetime option suits how you buy things

Opinion DNA is probably the better fit if

• •you want your values and moral reasoning measured alongside your temperament
• •you are curious about how you think: how certain you tend to be, how you handle ambiguity, and what you assume about the world
• •you would rather spend 10 to 15 minutes and pay once
• •you want to compare yourself with a partner, friends, a co-founder, or a team

Some people will want both. They cover different ground, and the overlap (mainly the Big Five) is small enough that taking one does not make the other redundant. Neither is a diagnosis, and both companies say the same thing about that: if something in your results worries you, talk to a qualified professional.

If the values and thinking-style side of the picture is what you are after, the full assessment takes about 10 to 15 minutes and comes with a 30-day money-back guarantee.
