Grey Mirror is a relationship communication analysis product developed by Wentropy Labs and available through JustLayMe. Textimony is a separate Wentropy Labs product for reviewing message evidence.

Wentropy Labs was founded by Layne Weant, whose work covers computational conversation analysis, natural language processing and privacy engineering. He is not a clinician or a lawyer, and neither Grey Mirror nor Textimony is a clinical or legal instrument.
