Track the questions buyers ask AI, not just keywords.
Proofsource tracks the real questions buyers put to ChatGPT, Perplexity, Claude and Google AI Overviews, grouped by topic, tagged branded or unbranded, and ranked by search demand. It also records the searches each engine runs behind the scenes before it answers.

Start from the questions that lead to a purchase.
Proofsource reads your site, your category and your competitors, then proposes the questions a buyer would ask an AI assistant before choosing. You review the list before anything runs. Questions sit in topics, so results map to the product lines you sell.
- A focused set of high-value questions, not thousands of keyword variants
- Grouped into topics that match what you sell
- Add, edit or retire questions at any time
| Topic | Questions | Mention rate |

See the searches AI runs before it answers.
Engines that browse the web split one buyer question into several searches, read the results, then write the answer. Proofsource records those searches where the engine exposes them. They tell you exactly which pages you need to rank for to be read.
- The hidden searches behind each answer, per engine
- Shows where your pages rank for each one
- Turns a vague AI question into concrete search targets
| Search the engine ran | Your page ranks |
|---|---|
| best 3 row electric SUV 2026 | Yes |
| electric SUV real world range family | No |
| Model Y vs R1S vs EV9 cargo space | Page 2 |
Rank questions by how many people actually search them.
Every question is matched to the keywords behind it and their monthly search volume. A question thousands of buyers ask, where AI leaves you out, goes to the top of the list. A rare one waits.
- Monthly demand beside every question
- Low mention rate on a high-demand question is flagged first
- Demand rolls up by topic
| Question | Demand / mo | Mention rate | Priority |
|---|---|---|---|
| Best electric SUV for a family | 12.1k | 75% | Hold |
| Is a home battery worth it | 8.1k | 25% | Act first |
| Best solar installer warranty | 2.9k | 0% | Act next |
Unbranded questions show whether AI finds you. Branded ones show whether it gets you right.
Unbranded questions never mention your name, so a mention there is earned. Branded questions name you, so they test whether the answer describes your company correctly. The free trial asks 25 buyer questions in your category plus a short set about your brand by name, today and tomorrow.
- Every question is tagged branded or unbranded
- The two are reported apart, never blended
- Wrong descriptions on branded questions show up in Accuracy
A branded question contains your name, so the name appears in the answer almost by default. Proofsource keeps the two apart so a high branded score cannot hide a low unbranded one.
Measure the questions that make a sale.
Questions, not keyword dumps
A short list of buying questions tells you more than a thousand phrasings nobody asks.
Demand decides the order
Search volume beside every question means you fix the gaps that reach the most buyers first.
The searches behind the answer
Query fan-outs show the pages an engine read, so you know where to show up.
Questions buyers ask
What is a prompt in AI visibility tracking?
A prompt is a question a buyer might ask an AI assistant, such as 'What is the best CRM for a 10-person sales team?'. Proofsource asks the same prompts on every engine and records whether your brand is named, where, and which pages are cited.
How does Proofsource choose which questions to track?
Proofsource reads your website, your category and your competitors, then proposes buyer questions grouped into topics. You review and edit the list before it runs, and you can add or retire questions later.
What is a query fan-out?
A query fan-out is the set of web searches an AI engine runs to answer one question. ChatGPT, for example, may search three or four phrasings before writing its answer. Proofsource records those searches where the engine exposes them.
What is the difference between branded and unbranded prompts?
An unbranded prompt does not contain your brand name, so being named in the answer shows the engine recommends you on its own. A branded prompt contains your name and tests whether the engine describes you accurately.
How many questions does the free trial include?
The free trial is 2 free scans, today and tomorrow. Each scan asks 25 buyer questions on ChatGPT, Perplexity, Claude and Google AI Overviews, plus a short set of questions about your brand by name. No card.
How much does Proofsource cost?
Custom plans start from $64 per brand per month. Final price confirmed at launch. Every plan includes the four core engines; you choose how many questions and brands to track.
