ONE PIN IS NOT PROOF
Position becomes trustworthy when independent signals agree.
Cross-check
Compare those witnesses in real time. A convincing fake signal becomes easier to expose.
Warn
Keep the trusted fused position visible and explain which source caused the conflict.
BUILT FOR THE MOMENT OF DOUBT
See the disagreement, not just the destination.
WHAMI turns raw sensor disagreement into a simple trust score, a clear map and an alarm you can act on.
- 01Fused positionThe blue WHAMI dot reflects agreement across sources.
- 02Source confidenceEvery witness remains visible instead of being hidden in one score.
- 03Explainable alarmsKnow what moved, how far it moved and why WHAMI is warning you.
