Communication DNA is your personal communication profile — a snapshot of how you give and take information, captured from a short survey and rendered as a six-point radar on your public profile.

It's the foundation everything else builds on: your "How to work with me" guideline, one-to-one compatibility comparisons, and every rewrite the Assistant produces are all calibrated to your DNA.

Unlike a personality test, it isn't about who you are — it's about how to communicate with you. Practical, not psychological.

Your DNA maps six dimensions, each on its own scale:

•  Directness — how blunt or softened you want messages addressed to you.

•  Sarcasm tolerance — how cleanly sarcasm lands with you, or whether it just confuses.

•  Irony tolerance — how readily you catch when someone means the opposite of what they say.

•  Assumption sensitivity — how much implicit context you want spelled out explicitly.

•  Ambiguity tolerance — how comfortable you are with open-ended, loosely-scoped asks.

•  Feedback style — how you best receive critique: direct, gentle, or questions-first.

For the full list of the 30 underlying factors we map, see the Communication DNA Factors reference page (/factors).

You set your DNA once, in a three-minute survey — about 30 questions, each mapping onto a factor. We never infer it from anything else: no log scraping, no behavioural tracking, no third-party data.

From your answers we generate the radar, write your guideline in your own voice, and power compatibility comparisons with teammates. Change any answer in your account settings and the next AI generation picks it up immediately.

Your DNA lives on your public profile at empatalk.app/u/your-name — built to be shared, with each answer's visibility under your control (public, team, or private).
