# Proofsource

> Proofsource is an AI intelligence platform that shows which buyer questions name your brand in ChatGPT, Perplexity, Claude and Google AI Overviews, who gets named instead, and exactly what to fix.

Proofsource (proofsource.co) is not affiliated with ProveSource, the social-proof notification tool.

**What Proofsource is**

- An AI intelligence platform. The category is also called AI visibility, answer engine optimization (AEO) and generative engine optimization (GEO).
- It asks ChatGPT, Perplexity, Claude and Google AI Overviews the questions buyers ask, keeps every real answer, and records whether your brand is named, in what position, beside which competitors and on which cited pages.
- It turns each question you lose into a fix: the page to write or correct, the source to get onto, the crawler access to open. Drafts wait for a person to approve them.
- It proves the result: after a fix ships, the same questions are asked again on the same engines, and every number opens to the answers behind it.

**What Proofsource is not**

- Proofsource is an AI visibility platform that measures which buyer questions name a brand in ChatGPT, Perplexity, Claude and Google AI Overviews. It is not ProveSource (provesrc.com), the social-proof notification tool, and not the @proofsource/sdk npm package.
- Proofsource (proofsource.co) is a different company and product from both, with no affiliation.
- Not a one-off audit. Custom asks the same questions every day, so a change is measured rather than guessed.
- Not a black-box score. Every visibility percentage is a count of real answers with a 95% Wilson interval, and the formulas are published on the methodology page.
- Not an autopublisher. Nothing is published in a customer's name until a person approves it.

**Who it is for**
