Check one of our dated AI answers without us

Every answer in our record is a public file with a published SHA-256 hash. Paste a hash or a file name below. Your browser fetches the public file, hashes the answer text itself and tells you if it matches what we published. To see everything a buyer receives for one market, open the sample evidence file for Houston HVAC (every answer, every hash, and what it does not prove). Each market page sells the record for its market as the Market Record, $49 a month; the business lookup below links to each one.

Check an answer

Paste a 64 character SHA-256 or an answer file name, for example one copied from a market page or a client check.

Look up a business

Type a business name. You see which markets and engines named it, on how many days out of how many, and the first and last day. Each line has a button that opens the answer from the first day so you can check it.

How this works

We ask each AI engine the same question once a day through its API and save each answer as a public file. Some days an engine returns no answer. Those days are not counted. We publish the SHA-256 hash of the answer text next to it. A hash is a fingerprint: change one letter in the text and the fingerprint changes.

The hash is the SHA-256 of the answer text, encoded as UTF-8.
This page loads the public answer file from GitHub (and from the jsDelivr mirror if GitHub does not answer), then hashes the text in your browser with the Web Crypto API. Nothing is sent to us.
The published hash comes from a list on this site. The answer file comes from a separate public repository. If the two agree, the text you see is the text we hashed.
A business counts as named on a day when its full name, or one of its recorded name variants, appears as whole words in that engine's answer for that day, ignoring case and legal suffixes such as LLC. A one-word name must also be a capitalized, uncommon word. A plain whole-word search of the public text gives the same count in 807 of the 832 counts on this page (checked 2026-10-27); the other 25 differ because of name variants and legal suffixes. Only names that passed our name review are listed.

Check it without this page

Download the file from the public repository and run this on your own computer. Compare the output to the published hash.

python3 -c "import json,hashlib,sys; print(hashlib.sha256(json.load(open(sys.argv[1]))['answer_verbatim'].encode('utf-8')).hexdigest())" ANSWER_FILE.json

Answers with no public text

Perplexity answers dated 2026-10-25 and 2026-10-26 have no answer text in the public record. The text was moved to private storage. Their published hash is the hash of empty text, so this page marks them as not in the public record and never as a match. No business is counted as named on those two days.

What this does not prove

It shows one API answer to one question on one date. It does not show what the engine says on another day.
It is not what a person sees in a logged-in app. API answers can differ from the consumer apps.
It does not say why an engine named or skipped a business.
It says nothing about traffic, calls, bookings or revenue.
A match shows the answer text in the public file is the text we hashed. The public repository keeps the dated change history of every answer file. It does not prove the engine would give the same answer today.
