North Signal

Where North Signal stands

Monitors show you the score.
We prove what moves it.

An honest comparison — including the things competitors genuinely do better. Every AI-visibility tool can tell you whether you were mentioned. Only a closed measure → prescribe → prove loop can tell you, with a held-out control, whether your fix caused the lift.

Multi-engine answer tracking
Variance-honest metrics (CIs, noise floor, run-count guidance)Engines are non-deterministic; single-snapshot scores are near-noise.
