What buyers ask before choosing an AI visibility tool
What is Proofsource?
Proofsource is an AI intelligence platform. It shows which buyer questions name your brand in ChatGPT, Perplexity, Claude and Google AI Overviews, who gets named instead, which sources the engines cite, and what to fix. It is not ProveSource, the social-proof popup tool.
How does Proofsource measure AI visibility?
It asks each engine the questions your buyers ask (every day on paid plans, 2 scans on the free trial) and records whether you are named, in what position and next to whom. Each number is a share of real answers with a 95% confidence range, and every answer is kept with its sources and a screenshot.
Which AI engines does it track?
ChatGPT, Perplexity, Claude and Google AI Overviews on every plan. Grok and DeepSeek are available as add-ons on Custom plans.
How often are answers checked?
Every day on paid plans. AI answers shift from day to day, so a weekly snapshot misses the day a rival enters your shortlist.
Is there a free trial, and how much does it cost after?
Yes. 200 answers. 25 Prompts/Question. Top AI engines. 2 days. Free. No card. Custom plans start at $64 per brand per month.
Does it only report, or does it help me fix things?
It ranks the gaps behind each lost answer by likely lift against effort, names the page or source to change, and drafts the fix from your own content for you to approve.
How is this different from SEO rank tracking?
Rank trackers measure blue links. Answer engines write one answer and name a few brands. Proofsource measures that answer: whether you are in it, who is in it instead, and which sources put them there.
The shortlist is being written right now.
