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.

Scores are interpreted as percentile anchors and profile interactions. A 28th percentile result does not mean “bad”; it means the trait is lower than roughly 72% of the comparison distribution, which changes how that trait is likely to combine with the others.

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 Anthropic’s Claude 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).

We do not let Anthropic train on your conversations — every call is made with the no-training, zero-retention setting enabled. Inference runs in an EU region for data-residency reasons.
