Peter James Steven
Detransitioner and creator of detrans.ai
When mainstream AI quietly erases detransitioner experience, Peter James Steven builds an alternative. His project detrans.ai treats detransitioner testimony as a structured body of evidence — a direct challenge to how AI shapes young people's choices at the very moment Britain is digesting the Cass Review and the closure of the Tavistock.
Peter James Steven came to the Beyond Gender podcast with a practical argument: that artificial intelligence, left unchallenged, will narrate gender transition as an uncomplicated good and leave detransitioner experience outside the frame. His answer was to build something — detrans.ai, a tool constructed from the ground up to take detransitioner testimony seriously as a coherent, consultable body of evidence.
In the episode detrans.ai: A Counter Narrative (February 2026), recorded with hosts Stella O'Malley, Mia Hughes and Dr Bret Alderman, Steven set out why the architecture of mainstream AI models matters for young people searching for information about gender. If training data excludes or marginalises detransitioner voices, the outputs will faithfully reproduce that absence. detrans.ai is his attempt to correct that bias by design rather than by complaint.
For British listeners, the timing is pointed. The Cass Review concluded that the evidence base for paediatric gender medicine was far weaker than had been claimed; NHS England withdrew puberty blockers for gender dysphoria; the Tavistock's Gender Identity Development Service closed. Yet the online information environment — AI chatbots included — has not automatically followed that evidentiary shift. A tool that deliberately centres people who have walked back from transition is, in that context, a form of counter-infrastructure.
Steven's project sits at the intersection of technology, testimony and advocacy. In a media landscape where detransitioners have routinely described feeling dismissed or disbelieved, detrans.ai proposes something concrete: that their accounts, taken together, constitute evidence worth consulting before a young person takes an irreversible step.
