Clear, visual answers from any codebase

Stop the "ask someone who knows" cycle

Without biral

The Old Way

  1. You need to understand how something works in the codebase A PM asking about refund logic, or a dev integrating with another team's service
  2. Slack someone who might know ⏱️ 10 minutes
  3. Wait for them to context-switch ⏱️ 4 hours (or 2 days)
  4. Get a partial, verbal answer Missing edge cases, outdated docs, no visuals
  5. Follow-up questions restart the cycle
Total Cost: Hours to days of waiting, blocked on someone else's availability, answer still incomplete
With biral

The New Way

  1. You need to understand how something works in the codebase
