The workflow
From audit to proof, in one loop.
Most tools stop at a dashboard. North Signal takes you from “where do we stand?” to “this change actually moved answers” — with the evidence to back it.
Audit your AI visibility
Run your prompts across ChatGPT, Google AI, Perplexity, Gemini, and Claude — many times — to see where you're mentioned, recommended, or absent.
See which competitors are cited
For every prompt you lose, see exactly who wins instead and which sources the models trust to recommend them.
Identify missing proof & content
Pinpoint the citations, comparison pages, and evidence gaps that keep you out of the answer.
Run recommended experiments
Get a ranked list of changes to test — each with the mechanism, expected lift, and effort.
Track lift across AI engines
Re-measure against a control. Only call it a win when the change moved answers beyond normal variance.
Sample report
A report that tells you what to fix next.
North Signal separates normal AI-answer variance from meaningful movement — so your team can make changes with confidence, not guesswork.

Method
Built for noisy AI answers.
AI systems vary by run, prompt, location, and retrieval path. North Signal repeats measurements, reports confidence, and validates changes against a control before calling a win.
Read the full methodologyMeasure
Run multiple prompts across models and locations. We repeat runs to capture variance and establish a baseline with confidence intervals.
Change
Make your change — content, structure, or entity signals. Keep everything else the same as the control.
Remeasure
Rerun the full set. We compare against the control using statistical tests and only report a win when it's reliable.
Simple pricing. Built for results.
Pay for proof, not for prompts. Plans meter brands and experiments — never measurement runs.

Trust & transparency
See the data. Trust the process.
Better decisions come from open methods and verifiable results — not a black-box score.
One thing we do differently: AI gives different answers every time you ask, so tools that show you a single score are guessing. We measure repeatedly and tell you what's real — even when the honest answer is “that change did nothing.”
