Be the brand AI recommends.
When your buyers ask ChatGPT, Claude, Gemini or Google who to use, two or three names come back, and the deals go to those names. Sentinel is how you become one of them: see where you stand today, get the exact work that wins the questions you are losing, and watch the proof build.
Free tier, free forever. No card.
Sentinel shows you, every week, whether ChatGPT, Claude, Gemini and Google recommend you or your rivals when buyers ask, and hands you exactly what to fix. From free, forever.
Sentinel is for B2B companies in considered-purchase categories where a shortlist decides the deal: consultancies, law firms, brokers, recruiters, agencies, software. If your buyers research before they buy, you already have an AI visibility number. The only question is whether you know it.
Your buyers ask. AI answers. Sentinel tells you whether it says you.
Buyers have stopped scanning ten blue links. They ask an assistant and get a shortlist of two or three names. If yours is not among them, the deal is forming without you, and nothing in your analytics will ever show it.
This answer decides a shortlist before your website gets a visit. Sentinel asks the engines your buyers' real questions, on schedule, and scores who they name. You see the moment, measured, instead of never knowing it happened. The names above are illustrative; yours will name your rivals.
From invisible to recommended.
Know where you stand
Where you are recommended today, and where you are not, across ChatGPT, Claude, Gemini and Google AI Overviews, on the questions that decide your category.
Win the questions you are losing
The exact buyer questions where rivals get recommended and you do not, with ranked fixes and ready-to-write briefs to take each one back.
Prove it to the board
One number, tracked over time, with your shipped work pinned to the chart. Progress you can show, not describe.
We were already watching your category.
Every check and every scheduled run since early 2026 feeds one continuous record of how AI engines recommend brands. Sign up and your category's history is already waiting, up to twelve months of it, from day one.
A number you can take to the board.
No black box. We ask real buyer questions, record real answers, and keep the receipts, so every figure on every screen can be traced back to what an engine actually said. The whole method is public and takes two minutes to read.
Sentinel sees it. Forge changes it.

Answered straight.
How do I know the score is accurate?
Every number comes from real, recorded answers. We ask the way a buyer would, repeatedly, on a schedule, and we keep the receipts, so any figure can be traced back to what the engine actually said. The How it works page shows the whole method in plain English; read it and check us against it.
Which AI engines does Sentinel cover?
ChatGPT, Claude, Gemini and Google AI Overviews, at every tier including free. We do not gate engine coverage by price; we gate frequency, depth and the act layer.
Do I need Forge to get value from Sentinel?
No. Sentinel is self-serve and complete on its own: the score, the gaps, the fix list and the briefs. Forge exists for companies that want the work done for them.
Can I cancel anytime?
Yes. Monthly plans cancel in one click, no calls and no notice periods.
