Works where you ask

ChatGPT, Gemini and Claude, right in Chrome.

AI makes up sources more often than you think.

Chatbots write citations the same way they write everything else: by predicting what sounds right.

18%

of GPT-4’s citations were completely made up in a study of 636 AI-written references. That’s nearly 1 in 5.

How it works

One click sends the AI’s answer through four steps. Quotik reads every cited source in the background, and its built-in AI compares each claim to the exact quote.

How Quotik checks an AI answer The AI answer is split into claims. Each claim's cited source is fetched, or looked up in research databases. Code finds and copies the exact matching quote. An AI judge compares only the claim and the quote. Results are underlined as made up, stretched, can't check, or verified. Made-up citations can loop back through Find a real source. 1. Claims2. Sources 3. Exact quote4.

The AI never writes the evidence. Every quote comes straight from the source.
