An internal Whatnot data tool that lets a PM pull nuanced cohorts, inspect individual user logs, and build sensitivity/forecast/regression models without needing a data scientist. It's one concrete instantiation of AI-Enabled PM Self-Service: Data, Code & Debugging — the specific tool, rather than the general practice, of PMs doing their own data work.
Use a self-serve cohort/modeling tool to investigate a bug report or metric shift directly against real user data, instead of routing the question to a data scientist first.
