Exploring the Inbox

The Inbox is where PostHog surfaces signal reports — clusters of related observations (signals) that have been aggregated into a single issue or trend (e.g. "Error rate spiked 3× on /checkout"). Reports come from multiple source products: error tracking, session replay, web analytics, experiments, and integrations like Linear, GitHub, and Zendesk.

Inbox is part of PostHog Desktop, PostHog's agentic surface for engineering teams.

Don't assume the user's project has reports, or that any signal sources are configured — plenty of projects don't have Inbox set up. Always run the setup-check workflow below before answering the user's actual question.
