Free AI visibility scan, explained in plain sentences

The free scan asks ChatGPT, Perplexity, Claude and Google AI Overviews the buyer questions you approved, then shows whether each engine mentions you, which competitors it names instead, which pages it cites and how much of your key content AI crawlers can read. Every new workspace gets one, for brands, apps and local businesses alike.

What is a free AI visibility scan?

An AI visibility scan asks AI answer engines the questions your buyers ask and records what comes back: whether your brand is mentioned, where it appears, which competitors are recommended and which sources are cited. It is the AI search equivalent of checking your Google rankings, except the answer is a paragraph, not a list of links, and it changes between runs.

Proofsource's free scan uses the questions you approved during setup and runs them on ChatGPT, Perplexity, Claude and Google AI Overviews. Results are read from stored answers, so every finding links back to the actual text an engine produced. Findings are written as plain sentences, such as which engine never mentioned you, rather than a single score you have to interpret.

The scan also checks how much of your key page content AI crawlers can see, and invites you to connect Google Search Console, Google Analytics and Cloudflare so later changes can be proven against traffic.

How it works

A free scan asks ChatGPT, Perplexity, Claude and Google AI Overviews your buyer questions and explains the result in plain sentences.

  1. Approve the questions

    The scan asks the questions you ticked during setup, nothing more.

  2. Watch it run

    A big answer count and one bar per engine fill as answers come in. If an engine is slow, a notice says so.

  3. Read the findings

    Plain sentences explain where you were named, where competitors were named instead and which pages were cited.

  4. See the crawler view

    The percent of your key page content AI crawlers can read, so you know if a technical block is part of the story.

  5. Connect to prove results

    Link Search Console, Google Analytics and Cloudflare after the scan so future gains show up in traffic too.

The buyer questions you approved in setup. You see and edit them before the scan starts.
