We measure humans.

99traits is the filmed personality test. You talk on camera for about 15 minutes, and we measure what you do: how you speak, pause, look and move. Each trait is placed among other people.

The same measuring works on any video of a person who agreed to it: a guided test, a talk, a vlog. It comes as a profile for people, as Pro for professionals, and as an API for builders.

Where we draw the line

• You measure yourself. The test measures one person, from your own video, with your consent. A recording with someone else taking part, such as a call, is not measured.
• Public videos are read, not shown. We read public videos to build and test our measuring, and we publish no one from them: no clips, no names, no results. A takedown request is honored within 24 hours.
• No diagnoses. We describe behavior in ordinary words and never name or suggest a medical or mental-health condition.
• Adults only. The test is for people 18 and over.

How the measuring works, and what it cannot tell you, is on the science page.
