Postmortem Witness - Incident bridge listener

During an outage, engineers are busy fixing the problem, not writing it down. The result is lost context, a timeline pieced together from memory, and postmortems that show up days late or not at all. Postmortem Witness is a voice agent that only listens. It joins an incident bridge call and never speaks or interrupts. It uses AssemblyAI real-time streaming transcription with speaker labels to capture who said what and when. As the call goes on, it pulls out the key moments (detection, hypotheses, actions taken, escalations, mitigation and resolution) and turns them into a timestamped incident timeline the whole team can watch update live. When the call ends, Postmortem Witness turns that timeline into a structured draft postmortem. The draft covers the summary, impact, timeline, root-cause hypotheses, what went well, what didn't, and action items with owners. Something that used to take hours of writing becomes a few minutes of review. It is built for SRE, DevOps and on-call teams that want accurate incident records without taking anyone off the fix. Responders can focus on the fire while Postmortem Witness keeps the record.
