Built on measured traits, not type lore.

Defaults uses an IPIP-style 120-item Big Five assessment. The Big Five is a trait model: it estimates continuous scores across Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism rather than assigning a fixed type.

Big Five scores are true norm-referenced percentiles: your raw answers are compared against the published adult norm tables from Johnson’s IPIP-NEO-120 research program (Johnson, 2014, Journal of Research in Personality) using z-scores and the normal distribution. A 28th percentile result does not mean “bad”; it means you scored higher than roughly 28% of the adult comparison group, which changes how that trait is likely to combine with the others. Percentiles are reported in the 1–99 range — no real reference group puts anyone at an absolute 0 or 100.

The shorter HEXACO assessment uses adapted items, so its results are shown as scores on a 0–100 scale (how strongly your own answers leaned on each trait), not as percentiles against a norm group.

Reports use cited research as constraints. The system is instructed to cite only from a curated corpus of Big Five, IPIP, outcome, cluster, and intervention papers, with DOI links shown in the report.

The free baseline (your five-domain scores and one anchor insight per domain) is entirely template-driven. No large-language-model is involved in generating it.

The paid report and the chat use Google’s Gemini models. Specific model versions are pinned in our code and updated only through a reviewed change — never silently. The generation step turns your facet scores into the six life-domain narratives; the chat answers your questions with your full facet profile included as context, so the advice is tuned to how you’re wired rather than generic.

What the AI can do: translate your scores into plain-language patterns, suggest scripts, surface trade-offs your profile suggests, answer questions about how to handle situations given your defaults.

What the AI can’t do: diagnose anything, replace a therapist, replace a doctor, replace a lawyer, or know things about you it wasn’t given. It doesn’t have access to the internet, your other accounts, or other users’ data. It can be wrong. Treat its output as a thoughtful starting point, not a verdict.

If a conversation touches suicide, self-harm, abuse, or a serious medical or legal situation, the assistant will append this message and step back from offering further advice:

This isn’t therapy and I’m not the right tool for what you’re describing. Please contact the appropriate emergency services or a qualified professional in your location.

We also run an automated review over conversations that get flagged this way. If a human review determines a response may not have been appropriate, we will notify you and surface the same safety message — without quoting the conversation in the email. This review is operated by a small team under the same access controls as everything else on your account.

Your assessment responses, generated reports, and chat history are kept for as long as your account exists, so you can come back to them. You can clear your chat history at any time from your account settings, and you can export or delete your account on the same page (deletion is a hard delete, cascading through all of your data within 30 days of the request).

The report and chat are generated by Google’s Gemini models, which process your inputs on Google infrastructure in the United States. We do not let Google use your conversations to train or improve its models — calls run on the paid Gemini API, where inputs and outputs are not used for model training.
