proof card / claim 3 · free workflow
Check Each Brand Claim Against the Proof You Actually Hold — Free
Paste your marketing claims and the card checks each for the number behind it, the source of that number, and when it was measured — leaving the unsupported ones visibly empty.
What this replaces
A claim audit tends to be a matter of taste. This checks four specific fields against what you pasted, so 'fastest setup in the category' is exposed as a line with no number, no source, and no date rather than argued about.
Tool note. This runs entirely in your browser — no account, no upload, no paid API key. Google NotebookLM is named as the free source-grounded reading path for the material you paste; its published free-tier terms were checked on 2026-09-13 and can change.
The four passes
Collect the smallest useful input
One claim per line, with its number, its source, and the source date.
Let the card check all four
Missing fields go to the top of the urgency lane.
Find the source or soften the claim
An unbacked superlative is the row to change first.
Recheck after the rewrite
A claim with a source and a date should pass all four.

The board below runs in your browser. It opens with a worked sample so the result is visible before you paste anything; switch scenarios, edit the text, or reset to the sample.

first-load · sample values are illustrative, not verified facts
Everything you paste stays in this browser tab. Nothing is uploaded, there is no account, and no request leaves the page to generate the result; clearing site data removes anything saved locally.
What breaks, and what to do
Comparative claims with no baseline
The number field stays empty; add what you are comparing against.
Internal data with no date
The date field flags it; internal figures go stale.
Legal review needed
This checks structure, not compliance; have counsel read the final wording.

The free board above is the whole loop. The paid tier keeps the arranged output so you do not rebuild it.
