Track your brand in every AI engine, one engine at a time
Proofsource asks your buyer questions on up to 10 AI engines, from ChatGPT and Perplexity to Gemini, Copilot and Grok, and shows results engine by engine. ChatGPT is read as a logged-out buyer sees it, every number names the engines behind it, and Proofsource publishes which model it samples each engine with. Choose your engines, run on your plan's cadence, or bring your own engine key.

AI engine tracking, explained
AI engine tracking means asking the same buyer questions on each AI assistant and recording how each one answers: whether it names your brand, where, next to which competitors and citing which sources. Each engine searches different sources and is tuned differently, so a brand can lead in ChatGPT and be missing from Perplexity. A single blended number hides that.
How an engine is asked matters as much as which engine. A logged-in developer interface can answer differently from the consumer app a buyer uses. Models change often, and a jump in your numbers can come from a new model rather than your work. Good tracking says which surface and model it read, and keeps engine results apart.
Proofsource tracks up to 10 AI engines, depending on your plan. ChatGPT is read as the consumer site a logged-out buyer sees. Google AI Overviews are captured through a chain of methods so a failed capture falls through to the next. Every number lists the engines behind it, and Proofsource publishes which model it samples each engine with and when that changed. The free trial runs four of them and the managed plan covers all ten.
How it works
Brand tracking on up to 10 AI engines, from ChatGPT and Perplexity to Gemini, Copilot and Grok, engine by engine, with the model behind every number disclosed.
Choose your engines
Start with the engines your plan includes and add more your plan allows.
Set the cadence
Background passes follow your plan's cadence, such as weekly or daily.
Ask each engine as a buyer
Each question runs on each engine, on the surface buyers use.
Record the model
Each answer is tied to the engine and model that wrote it.
Compare engine by engine
See mention rate, competitors and sources per engine, side by side.
See it in the product
Real screenshots from the Proofsource app show a live brand; drawn screens carry sample data for an example brand.
| Engine | Sampled as | Changed |
|---|---|---|
| ChatGPT | Consumer site, logged out | Oct 12 |
| Perplexity | Default search model | Sep 28 |

Every capability, live today
9 shipped capabilities behind AI engine tracking, each in the product now.
ChatGPT as buyers see it
ChatGPT answers are read from the consumer chatgpt.com a logged-out buyer sees, with a fallback so a question is not lost.
Google AI Overviews capture chain
AI Overviews are captured through a chain of methods; when one fails, the next one runs.
Google AI Mode and Microsoft Copilot
Track Google AI Mode and Microsoft Copilot answers on Managed or a custom plan.
Pick your AI assistants
Choose which extra AI assistants a brand tracks, within what your plan allows.
Engine model disclosure
Proofsource publishes which model it samples each engine with and keeps a release log of changes.
Engines behind every number
Each number states which engines it is based on, so a blended figure never hides a gap.
Bring your own engine key
Use your own key for an engine; Proofsource tracks spend against a cap and falls back or stops when it is reached.
Plan cadence
A brand's background passes follow its plan cadence, such as weekly or daily.
Day-one tracking of new models
Proofsource tracks new AI model releases from day one, so you see how answers change when an engine updates.
Who it is for
Find the weak engine
See which engine leaves you out and focus there first.
Explain a sudden jump
Check the model release log before crediting or blaming a campaign.
Use your own engine account
Run sampling on your own key with a spend cap your team controls.
Report per engine
Show clients where each assistant stands, not one blended number.
Why it matters
What buyers see
ChatGPT is read as a logged-out buyer sees it.
Transparent method
The model behind every engine is published, with a change log.
Resilient capture
AI Overviews fall through a chain of capture methods instead of going blank.

Questions about AI engine tracking
Which AI engines does Proofsource track?
Up to 10 AI engines, depending on your plan: ChatGPT, Perplexity, Claude, Google AI Overviews, Google AI Mode, Gemini, Microsoft Copilot, Grok, DeepSeek and Meta AI. The free trial and free scan run the first four; the managed plan covers all ten.
Is ChatGPT tracked the way buyers use it?
Yes. Proofsource reads the consumer chatgpt.com a logged-out buyer sees, with a fallback so a question is not lost when that read fails.
How are Google AI Overviews captured?
Through a chain of capture methods. If one method fails for a question, the next one runs, so you do not get gaps from one failure.
Which model does Proofsource use for each engine?
Proofsource publishes the model it samples each engine with day to day, and a release log of when that changed, so you can tell a model change from a real change in your visibility.
How often are my questions asked?
On your plan's schedule, weekly or daily, and you can also run a question now from the app.
Can I use my own engine API key?
Yes. You can bring your own key for an engine. Proofsource tracks spend on it against a cap and falls back or stops when the cap is reached.
Why show results per engine instead of one score?
Engines search different sources and often disagree. Per-engine results show where you are missing, and every blended number lists the engines it covers.
How is this different from Rankscale or Profound engine coverage?
Rankscale and Profound track a wide list of engines, which is a real strength. Proofsource tracks up to 10 engines, reads ChatGPT as buyers see it, and publishes the model behind each engine.
