Best AI visibility tools (and what to look for)

As buyers move their research into ChatGPT, Gemini and Perplexity, a new category of software has appeared to answer one question: what are the AI engines actually saying about my brand? These are AI visibility tools (sometimes called AEO or GEO tools). This guide explains what they do, what to look for, and the ones we build at Northstar Digital.

What an AI visibility tool does

At its core, an AI visibility tool runs the real questions your buyers ask AI engines, captures the answers, and turns them into metrics you can manage. The good ones tell you four things:

• Coverage / Share of Voice — how often you surface for your category's buying questions, per engine.
• Sentiment — whether the engines describe you positively, neutrally, or steer buyers elsewhere.
• Competitor gap — who wins the questions you are absent from.
• Citations — which sources the engines trust to recommend brands in your category.

What to look for

Coverage of all the engines that matter (ChatGPT, Gemini, Perplexity, Claude — and Google AI Overviews); measurement that goes beyond a single score to show why you win or lose a query; and, crucially, a path from diagnosis to action. A dashboard that tells you that you are invisible but not what to publish about it is half a tool.

The tools we build

Northstar Digital builds its AI visibility stack in-house:

• Beacon — our flagship. It tracks your AI Share of Voice across engines, shows the questions you are losing and who is winning them, surfaces the sources AI trusts, and turns it into a publishing plan.
• The free AI visibility audit — a no-cost Beacon snapshot of where your brand stands across four engines, in 48 hours.
• Anchor — the content engine that closes the gaps Beacon finds, engineered for AI citation.
• Prism — a PR audit that tests whether your earned media is actually being absorbed by AI engines.

Tool or partner?

A tool measures; a program moves the number. For Indian brands new to this, the fastest start is to see the data first — run the free audit — then decide whether to act on it yourself or with our answer engine optimization services. Either way, start from measurement, not guesswork.
