// The AI Source Checker

Did your AI’s sources actually exist?

AI hands you links, papers, and book titles with the confidence of a waiter reciting specials the kitchen has never heard of — and some of them simply aren’t real. Paste an answer below. We pull out every source it cited and check which ones are really there, then tell you, plainly, which ones aren’t.

Paste an answer an AI gave you. We pull out every link, paper, and book it cited, then check which ones actually exist — and tell you, plainly, which ones don’t.

The AI answer to check

Here’s one we ran earlier — clear it and paste your own.

This checker runs in your browser. With JavaScript on, it pulls every link, paper, and book out of the answer above and checks each one against the live web and the academic indexes. In the example above: two sources resolve, one link (an FDA page) is a dead 404, one book number doesn’t add up, and one claim came with no source attached at all.

// Then check what they SAY

We can’t read the source for you — so make the AI do it, in front of you.

A working link still isn’t proof the source backs the claim. The honest way to test that is to put the AI back on the stand. Copy this into the same chat, paste it under the answer you’re checking, and watch whether it can point to the exact line — or whether it starts hedging.

Go back through your previous answer and, for every factual claim, do the following:

1. Name the single source that supports it.
2. Quote the exact sentence from that source that backs the claim — word for word. Do not paraphrase.
3. Give the direct link to where that sentence appears.
4. If you cannot find a sentence that directly supports a claim, say so plainly: "No source directly supports this." Do not fill the gap.

Rules: do not invent quotes or links. If a source only partly supports a claim, say which part it supports and which part it doesn't. I would rather you tell me you can't back something than make something up.

What this catches, and what it can’t. A source that exists isn’t a source that’s right — we check the link, paper, or book is real, not that it says what the AI claimed. And we can only check sources the AI actually cited: a confident claim with no source attached is the one this tool can’t catch, and the one you most need to.
