Understudy vs Stack Overflow for Teams

Q&A works great — if someone knows what to ask.

The Question You Never Think to Ask

Stack Overflow for Teams brings the familiar Q&A format inside your company. Engineers post questions, experts answer, and over time you build a searchable knowledge base. The format works — Stack Overflow proved that across the entire software industry.

The problem is what doesn't get asked. The junior developer doesn't know to ask why the payment service retries exactly three times. The new hire doesn't know to ask about the undocumented dependency between the auth service and the legacy user table. The contractor doesn't know the deploy process has two steps that aren't in the runbook because "everyone just knows."

Understudy flips the model. Instead of waiting for someone to ask the right question, it interviews your experts and pulls out the knowledge proactively. It asks the follow-up questions your new hires don't know to ask. It digs into the edge cases your seniors take for granted. The result is documentation that covers the gaps a Q&A board never reaches.
