His Dot debugged a Substack signup bug on its own

posted Oct 12, 2026

My AI agent doing proactive customer service: Someone emailed me that, after subscribing to my Substack, they were automatically signed up for others (which shouldn't happen). Without my asking, my Dot ran its own test & figured out what happened by trying to replicate the error.

First-hand X post by emollick (Ethan Mollick): after a reader reported being auto-subscribed to other Substacks, his OpenAI Dot proactively ran its own test, replicated the error, and figured out what happened — without being asked. Screenshot attached showing the Dot's investigation.

My dot negotiated by email to cancel a subscription — and won

Puse a mi agente de OpenAI (dot) a "pelearse" por correo para cancelar una suscripción de una conocida fundación que hace hasta lo imposible por no quererte cancelar. Y al fin lo logró. Ahora tengo a mi agente configurado para monitorear todas las fechas de vencimiento de mis suscripciones y cancelarlas/pausarlas a tiempo. El futuro es ahora.
