The claims-and-evidence worksheet
A free spreadsheet for recording each wrong AI claim about your business, where it may come from, what you changed and what happened next.
Published
It opens in Excel, Google Sheets, Numbers and LibreOffice, and it’s free to use and adapt. The first rows of each tab describe a fictional bakery; delete them when you start.
What each tab records
| Tab | One row per | Main fields |
|---|---|---|
| Claims | wrong claim | The claim word for word, the truth, the finding |
| Observations | answer you checked | Date, AI product, prompt, whether the claim appeared, links |
| Sources | page you checked | URL, date read, what it says, whether it supports the claim |
| Interventions | change you made | What changed, where, and the date it went live |
| Summary | claim | Calculated: checks and appearances before and after your first change |
How to fill it in
Before you record any answers, read each AI product’s terms. Some limit recording, even by hand.
- Give each wrong claim an ID on the Claims tab, such as C-01. Copy the claim exactly.
- Add a row to Observations every time you check, including when the claim doesn’t appear.
- Reuse the exact prompt for later checks.
- Add every page you read to Sources, with the date, even if it doesn’t support the claim.
- Date each change on Interventions by when it went live, not when you asked for it.
The Summary tab fills in by itself.
Choosing a finding
The Claims tab asks for a finding: source error, unsupported statement or source unknown. Leave it as “Not yet checked” until you’ve followed the guide.
Reading the before-and-after counts
Check the same prompt several times on each AI product, before and after a change. If the claim stops appearing, the record shows that the answer changed. It can’t show that your change caused it.
