Every business in the market, on one dated record. 27 of 58 carry at least one fact verified against a public register. Mentions from ChatGPT, Gemini and Perplexity in September 2026 are an input on the receipt, never a rank. Each row opens the full free receipt.
This is the baseline edition. Every future edition is measured against it, and it cannot be back-dated.

This is one of the published questions from the HVAC probe battery, word for word. Paste it into ChatGPT, Gemini or Perplexity. Mentions are an input on the receipt, not a score.

Leave the name you searched and your email. Request coverage for the Chicago HVAC record. We record confirmed requests for review. Automatic first-appearance alerts are not available yet; this does not start a change alert.
Order is alphabetical. We publish what a public register says about each business, the date we looked, and which assistants named them this edition as an input. We do not rate businesses against each other. Read the method.
Owner watching
First month free, then $149 a month.
Know what your record says, and when it changes. Watching starts when your card is on file and the free month begins. The first briefing may go out before any charge. A subscriber gets the baseline briefing, the monthly readout, the change alert for published changes, and the weekly digest for the selected business. The public receipt and seal remain free. No login. Cancel with one reply. Paying cannot move your receipt, which is the whole reason it is worth reading.
Type the business name, or search above first. We email once when its receipt moves. Free, double opt-in.
Weekly digest
One email a week with everything that changed across the market: which receipts and facts on the record moved. Free, double opt-in, unsubscribe in one click.
The paid digest covers the selected business. Public market subscriptions are separate opt-in lists.
Another trade or city?
Chicago restaurants is live and flagship; Chicago HVAC is live as the second market. Tell us your trade and city if you want the next market.
Requests decide which market opens next.
Payment never touches the record. Every business here has a free public receipt whether it has heard of us or not. We sell watching. We never sell the record or leads.
