Detection that finds what's costing you conversions.
Every issue is ranked by estimated revenue impact, comes with a likely cause, and tells your team where to verify the fix. Checkout errors, conversion drops, performance issues, traffic anomalies, tracking gaps — detected before your next weekly report.
- Revenue impact estimated from affected sessions — prioritize by money, not volume
- Browser, device, and page-level cause breakdown per issue
- Suggested fix with the specific path and component to investigate
How we get the €: affected sessions × your store's average order value. Haven't mapped revenue yet? You get the drop-off % instead — never a made-up number.
Proof the fix worked.
Every resolved issue is measured with a controlled before/after — what you fixed, what it recovered, and how often fixes stick.

Ask anything. Every answer is verified.
Plain-English questions over your real sessions, conversions, and traffic — every answer checked against your metrics before you see it, or an honest "I can't verify that yet." The detection underneath runs on fixed rules — the AI never invents a problem, it only ranks and explains them.
