AI Visibility Tracker vs Fenn

Both are ours, and they are built for different people, so this page is written to send you to the right one rather than to the more expensive one. <strong>Fenn</strong> is a hosted service that tracks brand mentions across ChatGPT, Claude, Gemini, Perplexity and Grok and then writes the actual change — showing a unified diff and opening a pull request for a human to approve — from $29/month, with a genuinely free tier and a hosted MCP server. <strong>AI Visibility Tracker</strong> measures the same loop on your own machine for $29 once and does not touch your code. If you want the fix automated, use Fenn. If you want the measurement owned outright with no vendor in the path, use this.

What does Fenn do that this app does not?

It closes the loop. AI Visibility Tracker tells you which prompts you lost and generates an opportunities plan; a human then goes and does the work. Fenn writes the change itself, shows you the unified diff, and opens a pull request you approve or reject.

Fenn also ships a hosted MCP server, so you can ask about your visibility from inside Claude or ChatGPT as a custom connector rather than opening a dashboard at all. There is no equivalent here, because a desktop app with no vendor cloud has nothing to expose as a hosted endpoint.

And Fenn has a free tier that does not expire — one domain, five prompts, ten keywords and the MCP server. This app has a 7-day trial and then asks for $29.

Why would you pay once instead of using Fenn&rsquo;s free tier?

Prompt count is the honest answer. Fenn&rsquo;s free tier covers five prompts on one domain, which is enough to see whether you appear at all but not enough to track a category. This app has no prompt meter — define thirty questions if that is what your buyers actually ask, and every one runs daily.

The second reason is that nothing leaves your machine. There is no vendor cloud, no account and no server of ours in the path, which matters if the prompts themselves are commercially sensitive — competitor names, unreleased positioning, pricing comparisons you have not published.

The third is arithmetic that only works one way. $29 once against $29/month is a twelve-times difference in year one, but only if the measurement is all you wanted. If Fenn&rsquo;s automated fixes save you an hour a month, the subscription pays for itself and the comparison stops being about price.

Which one fits an agency?

Fenn, fairly clearly. Its Agency tier is built around 25 client workspaces and 250 tracked prompts, which is a shape this app does not have — there are no workspaces here, no client separation and no shared dashboard.

You can run this app across several client sites, because there is no per-domain licence, but the reporting is per-run on your machine rather than a portal a client can log into.

For a solo consultant with a handful of clients that is often fine. For an agency with a team and client logins, it is not, and buying the cheaper tool would be a false economy.

Can you use both?

Yes, and there is a sensible split. Use this app for continuous, unmetered measurement across every prompt you care about, on your own machine. Use Fenn on the domains where you want the fixes written and shipped rather than listed.

They are not integrated — no shared account, no data exchange, no single dashboard. They are two tools from the same portfolio that happen to point at the same problem from opposite ends: one measures without touching your site, the other changes your site and asks for approval.

What are the limits of each?

This app measures and never fixes. If reading a list of lost prompts does not reliably turn into work getting done, the measurement will not help you, and Fenn&rsquo;s pull requests will.

Fenn requires trusting a hosted service with a connection to your repository, and requires a subscription that keeps running for the tracking to keep running. Stop paying and the tracking stops; this app keeps working because the licence is verified on your machine.
