Who built Grey Mirror?

Layne Weant is the founder of Wentropy Labs and the creator of Grey Mirror, a system that analyses complete exported message histories rather than isolated screenshots. The work sits at the intersection of computational conversation analysis, natural language processing and consumer AI, with a privacy posture that treats a message history as the most sensitive thing a person owns. Not a clinician, therapist or lawyer, and Grey Mirror is not a clinical or legal instrument.

  • Computational conversation analysis: measuring reciprocity, escalation, rupture and repair across a full history instead of a sampled moment.
  • What Grey Mirror measures across a full history, and the evidence that ties every claim back to specific messages.
  • Consumer AI product design: making a measurement system legible to someone in the middle of a hard week, without overclaiming what it knows.
  • Privacy engineering: aggregate-only publication, anonymisation before scoring, and suppression of small cohorts.
  • Published position: a screenshot is the weakest possible evidence about a relationship, and the most commonly used.
  • Published position: a tool that measures patterns should publish what it cannot show, next to what it can.
  • Featured in Informatics Magazine (September 14, 2026), in an expert roundup on when metrics built outside a central analytics platform should come under shared definitions.
  • Author of “The Signal Is Rare: What Millions of Text Messages Can Tell Us About How People Communicate,” published by Linguistics News on September 25, 2026.
  • Author of Relationship Texting Benchmarks 2026, the aggregate study of reciprocity, conflict and repair published at justlay.me/research/relationship-texting-benchmarks-2026.

Layne Weant founded Wentropy Labs and built Grey Mirror, a system that reads a complete exported message history rather than isolated screenshots. The work sits across computational conversation analysis, natural language processing, machine learning and privacy engineering, and it is published rather than described: the methodology, the data dictionary, the provenance audit and the underlying CSVs are all downloadable from the research pages.

The published output is the credential worth checking. Two observed cohorts of complete relationship-message histories have been released -- a 29-history signal cohort covering 4,600,611 messages from 20 accounts, and a 44-history conflict cohort covering 2,994,932 messages -- alongside a synthetic turning-point benchmark, each with its scope and its limits stated. The eligibility funnel behind the cohorts is published in full, from a 347-conversation operational universe down to the 29 histories that were actually released.

One reply-latency measure was withheld because the data split 9 to 13 on direction and did not support a claim. That decision is documented on the research page rather than quietly omitted, and it is the clearest available statement of how findings here are handled: figures are attributed to the cohort they came from, cohorts are never summed, and a measure that does not hold is published as withheld rather than dropped.

Grey Mirror ships on the web, as a free native Mac app that reads the Messages and Apple Mail conversations already on the machine, and as a free iPhone app, with one account across all three. Mirror Veil, a separate free tool that strips names, numbers, emails and addresses from a transcript entirely inside the browser with nothing uploaded, is published as open source with a security policy.

Informatics Magazine featured Layne on September 14, 2026 in “Tame Shadow Analytics While Preserving Team Autonomy”, an expert roundup on metric governance. His answer drew on Grey Mirror: a measurement can be tried several ways while it is being built, but once a user sees it, it must mean the same thing in every report.

Linguistics News published Layne's bylined article “The Signal Is Rare: What Millions of Text Messages Can Tell Us About How People Communicate” on September 25, 2026. It discusses full relationship-message timelines, published Grey Mirror research and the limits of interpreting a single text.
