REFLECTION

Honest takeaways

The biggest improvement was clarity, not complexity. Simplifying the detection flow, surfacing confidence scores, and providing actionable humanization suggestions helped users trust the results and complete scans faster.

What I'd do next

  • 01Introduce sentence-level AI detection insights.
  • 02Test one-click humanization with multiple writing styles.
