Yank Check

Did they really say that?

Paste the quote and a link to where it’s from: a podcast, an interview, a hearing, an article or a PDF. Yank reads the source and shows you whether the words are in it, and where.

A check publishes nothing. It says whether the words are in the source, never whether they are true.

The five answers

Found
The exact words are in the source, and Yank shows you where: the second of a video or podcast, the passage of an article, the page of a PDF.
Close match
Nearly the exact words. The words that differ are printed, never hidden behind a similarity score.
Distilled match
Not the source’s literal words, but one passage shares most of them. The passage is shown, so you can judge whether it says the same thing.
Not found
Yank read the whole source and the words are not in it. That is a claim about what Yank read, the captions, the transcript, the article text, not proof that nobody ever said them.
Can’t establish
Yank couldn’t read enough of the source to say either way: a paywall, a login, or audio that would have to be transcribed first. It says which.

What it reads

A YouTube video with captions, an article anyone can open, a public PDF, and any source Yank has already yanked are checked straight away. A podcast or a video without captions has to be transcribed first, so the check asks you to yank it once; after that, checks against it are immediate.

No model decides a verdict. Yank compares the words against the source it read, with the same guard that checks every line it publishes.

For agents

The same check is a tool: check_quote on the Yank MCP server, or POST /api/check with a statement and a source. AI writes the answer; Yank provides the receipt.
