Ghostart vs Profound vs Semrush vs Scrunch: which AI visibility platform fits

If you've asked ChatGPT or Google's AI who's good at something in your field, you already know the real question isn't "does an AI visibility tool exist." It's which one does the job you actually need done.

Some tools are built to measure whether AI names you. Some are built to help you fix it when it doesn't. Most people shopping this category assume those are the same job. They aren't, and the platforms worth putting side by side — Ghostart, Profound, Semrush and Scrunch — split roughly along that line.

This page sets out what each one is built to do, sourced from what each company has published about itself, so you can work out which job you're actually hiring for.

What each platform is actually built to do

Profound tracks how your brand shows up across AI answer engines, built for teams that need enterprise-grade answer-engine monitoring and reporting.

Semrush folds AI visibility into its existing SEO platform: tools for monitoring mentions, citations, competitors and prompts sit alongside the rank-tracking and keyword tools its customers already use.

Scrunch focuses on the layer between your site and the AI agents reading it, making sure your content is structured in a way agents can parse and represent accurately.

Ghostart covers the full loop: finding which questions you're missing from, planning and drafting content with your own people's expertise in it, publishing it across channels, and re-checking monthly whether the gap closed. Tracking is the start of that loop, not the whole of it.

Where Ghostart is the better choice

Ghostart is built for businesses that have already worked out the problem isn't just knowing whether AI mentions them. It's that nobody inside the company has time to turn real expertise into the kind of content AI actually cites.

We start by finding the specific questions your buyers are asking where you're absent and a competitor is named instead.

From there, we help your own people — the ones who actually hold the expertise, not a generalist writing around it — turn that into published content scored for citability before it goes out, not after. We publish it across LinkedIn, WordPress, Ghost and your own site blog, and we re-check monthly whether the gap closed.

That's the difference for a founder-led firm or a lean marketing team: you don't need a second subscription to interpret the dashboard. The measurement and the fix live in the same workflow, run by the people who already know the subject.

We also rotate how we ask each tracked question, three phrasings a week, so a result isn't the luck of one wording. When you do get cited for something, we surface the next adjacent questions worth going after rather than leaving you to guess what comes next.

If what you're missing is visibility and the capacity to act on it without hiring a second team, that's the gap Ghostart is built to close.

Where Profound is the better choice

Profound is built for teams that need to monitor brand presence across answer engines at scale, with the kind of enterprise reporting a larger marketing organisation expects to hand upward.

If your main problem is visibility into what's already happening — which assistants mention you, how often, in what context — and you have the people in-house to act on what the dashboard tells you, Profound is built for exactly that job.

Where Semrush is the better choice

Semrush's advantage is that AI visibility isn't a separate purchase for anyone already running their SEO through it. Its AI-visibility tools sit next to the keyword, rank-tracking and competitor features a marketing team already uses daily, so mentions and citations get watched from inside a platform many teams have already built workflows around.

The two problems aren't as linked as they look. Good Google rankings don't guarantee AI visibility, and a tool that already has your SEO data is well placed to show you where the two diverge.

If your team lives in Semrush already and wants AI mentions tracked alongside the metrics it already watches, that continuity is the real reason to stay.

Where Scrunch is the better choice

Scrunch's case rests on the layer most visibility tools don't touch: whether AI agents can actually crawl and accurately represent your site when they reach it. That's a narrower, more technical problem than brand monitoring, and it's one a lot of otherwise well-covered businesses get wrong without noticing.

If your content is solid but you suspect the problem is structural — agents misreading or skipping pages that should qualify you for an answer — Scrunch is aimed squarely at that layer.

The decision in one place

None of these four are solving quite the same problem, which is the point. Ask which part of the loop you're actually missing — visibility, SEO continuity, agent readability, or the people-and-content system to close the gap — and the right choice gets a lot clearer than the category name suggests.
