Take the adaptive assessment
5 minutes for first insights, ~25 for the full read. MUPP-CAT picks each next question from the 754-item bank based on your previous answers — fewer items, sharper estimates.
SELF-DISCOVERY · PSYDNA LAYER
Make your AI understand you — not just remember you.
Take 5–25 minutes. Get a portable PsyDNA profile every AI you connect can read. Personalization starts on message zero — never training material, deletable from Dashboard at any time.

How it works
From cold-start to AI that gets you, in four steps.
2
Get your 15-dim PsyDNA
Theta + standard-error per dimension. Confidence bands on every score. You see what's measured confidently and what's still noisy — no fake precision.
3
Connect any AI
Use TraitTune's built-in chat (TT-FREE / TT-PRO) or BYO your existing AI-chat subscription — your profile reads into either, under our privacy umbrella.
4
Refine as you go
Single-dimension retake when you sense drift. The instrument updates with you. Cross-PsyDNA matches with friends and team come for free once your profile exists.
Playground · try it
Pick a prompt. See the gap with vs. without your PsyDNA.
Two assistants, same question. Left reads your TraitTune profile. Right guesses from chat logs. Click any prompt — the answers stream side-by-side.

TT-Pro
Answers generated by LLM · your profile data stays unrevealed and secure to the LLM under the TraitTune's umbrella.
Not live — illustrative sample. Memory replays your transcript; the profile reflects who you actually are. Try the real thing
What you actually get
Self-discovery — how you actually work.
Five priority dimensions for personal growth, with the same narrative depth as the full profile. Scroll inside the actual /results view.
What we don't do
We refuse the AI-memory default.
Dump every chat into a vendor database that may be used to train the next model version.
Measure once, structurally. Calibration runs on anonymized item-responses only — never on individual profiles.
Lock personalization behind one vendor's chat. Switch models and start over.
Portable profile. The same PsyDNA reads into TraitTune chat, your favorite AI assistant, or a local model — your choice of LLM, same understanding.
Make deletion a customer-support flow. Hide the off-switch.
Delete button in Dashboard. One click, one confirmation, every response gone. No ticket.
Privacy
Three things we will never do.
Never training material
Your PsyDNA profile is encrypted at rest. It is never used to train any AI model — ours or anyone else's. The calibration that improves the instrument runs on anonymized item-response data only, never on individual profiles.
Never sold, never shared by default
We do not sell raw responses, do not share with third parties by default, and never reveal a profile to another person without explicit per-connection consent that you can revoke.
Never hidden from you
There is a Delete button in your Dashboard. One click removes your profile and every response. No service ticket, no negotiation, no "are you sure?" guilt trip.
