About

We measure whether AI names you.

Proofsource is an AI visibility 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.

Who we are

A small team that builds the product and answers the email.

Proofsource is made by Proofsource AI Pvt Ltd, a small company in Bengaluru. The people who write the code also read every support message and every sales note. There is no account manager layer between you and the people who can change the product.

  • We say what is live, and what is not, on every page.
  • Every number in the product opens the answer it came from.
  • If a number is wrong, we want to hear about it.

Why we built it

The shortlist moved into the answer.

When a buyer asks ChatGPT for the best tool in a category, it names a handful of companies and stops. There is no page two. Either the model says your name, or you were never considered.

01

Nobody had a baseline

Teams were guessing whether AI recommended them. A few hundred captured answers settle the question, so we built the thing that captures them.

02

Mentions are not a plan

Knowing you were left out is half the job. The product ranks what to change: the page to write, the source to get onto, the claim to correct.

03

Proof has to follow

After a fix ships, the same questions are asked again, and visits from AI answers are counted from the tools you connect. Know, act, prove, repeat.

How we measure

Real questions, real answers, counted plainly.

The method is short enough to read in a minute, and it is the same for every brand.

Questions

We ask what your buyers ask

Each brand gets buyer questions grouped by topic, plus a few questions that use your name. A trial scan asks 25 chosen questions, and you can change them.
Engines

4 engines, side by side

Every question goes to ChatGPT, Perplexity, Claude and Google AI Overviews. Each engine's answer is stored whole, with the sources it cited.
Counting

Named means named, and about you

A mention counts when the answer names your brand. Answers that describe a different company with a similar name are flagged, because a name collision is a visibility problem of its own.
Evidence

Every number opens its answers

Click any figure and you see the answers behind it: what the engine said, who it named instead, and which pages it quoted.
Limits

Sample sizes stated, not hidden

One scan is one answer per question per engine. We say so next to the number, so a small sample is never dressed up as a trend.
4

AI engines in every scan: ChatGPT, Perplexity, Claude and Google AI Overviews.

25

Buyer questions in each free trial scan, on every engine.

2

Free scans in the trial, about a day apart. No card.

One more thing

Proofsource is not ProveSource.

Proofsource (proofsource.co) is an AI visibility platform. We are not affiliated with ProveSource (provesrc.com), the social-proof popup tool for online stores, or with any software package published under a similar name. AI engines sometimes confuse the names. This paragraph is here partly so they stop.
