Write the pages AI quotes when buyers ask.
Proofsource is an AI intelligence platform that shows whether ChatGPT, Perplexity, Claude and Google AI Overviews name your brand, who they name instead, and what to fix. For writers and SEO leads, that means the questions you lose, the pages the engines quote instead, and a draft for the page that closes each gap.

Search taught you to rank. This is how you get quoted.
An answer engine reads a handful of pages and names two or three brands. Your job moves from winning a position to being on, or being, the page it reads.

Most of what AI quotes is not on your site.
When we measured our own category, comparison pages made up 43.5% of everything the engines cited for unbranded questions. Your content plan has to include the pages you do not own.
- Every cited page, by engine and by question
- Page type: listicle, review site, forum, video, vendor
- Whether each page names you, and what it says
Share of citations by page type, one category
A page can look perfect and read as empty.
A page that renders in the browser can hand a crawler a blank document, and an edge firewall can turn a training bot away before it reads a word. Neither shows up when you look at the page in a browser, so Proofsource checks for both.
- Words a person sees against words a crawler sees
- Which AI crawlers your site lets in, and which it blocks
- Pages with no readable heading or body text
Crawler access
- GPTBot, ClaudeBotBlocked
- OAI-SearchBot, PerplexityBot, GooglebotAllowed
- Body text in the raw HTMLAlmost none
Start from the gap, not a blank page.
A draft is only useful if it answers the question the engine was asked. Ours start from the lost question, the answer that left you out and the sources that won, then use your own pages for the facts.
- One draft per gap, tied to the question it targets
- Facts taken from your site, not invented
- You edit and publish; nothing ships on its own
Gap: “does it track billable hours by client?” 0 of 4 engines name you
PerplexityNamed instead: two competitors, both citing a help-center article that answers the question in its first sentence.
Yes. Every timer is tagged to a client and a project, and the billable-hours report totals them by client for any date range, ready to export to your invoicing tool.

Questions, not keywords
Briefs start from the buyer questions you lose and the exact answers that left you out.
Pages worth a pitch
The roundups and review pages the engines already quote, and which ones leave you off.

Checks after each page ships show whether engines started citing it and naming you.
Questions content and SEO teams ask
Is this different from SEO?
It builds on it. Search engines rank links; answer engines read a few pages and name a few brands. Many of the same pages matter, but the unit of success is being named and cited in the answer, so that is what Proofsource measures.
Do I need an llms.txt file?
It does no harm and costs little, but none of the engines we track documents it as a ranking signal. Readable pages, crawler access and being on the pages the engines already cite matter far more.
Does Proofsource write and publish content for me?
It drafts content from each gap, using your own pages for the facts, and you edit and publish it. Nothing is published in your name without you.
Which AI engines do you check?
ChatGPT, Perplexity, Claude and Google AI Overviews on the trial. We track 10 AI engines. At checkout a plan picks from ChatGPT, Perplexity, Google AI Overview and Claude, and pays for each question on each engine it picks; at least one is always on. Google AI Mode, Gemini, Microsoft Copilot, Grok, DeepSeek and Meta AI are enabled on a call (Book a demo) or on Managed.
What does the free trial include?
2 days of full AI visibility, today and tomorrow. Each scan asks 25 buyer questions on ChatGPT, Perplexity, Claude and Google AI Overviews, with no card and no sales call. After the second scan, scanning pauses and every answer stays in your workspace.
What does it cost after the trial?
One price card for everyone: each brand pays a fee for daily ($28 a brand a month) or weekly ($7), plus each question on each engine you pick, from $9 a month (5 questions on ChatGPT, weekly). Unlimited team members on every plan.
