See ChatGPT, Gemini, Claude or any AI say something off? Check it against 3 AIs at once instantly, and if it's wrong, put it on the record for a BUSTED / CLEARED verdict. No install required.
The fastest way on a computer. Drag Check with 3 AIs up to your bookmarks bar once. Then on any AI page: highlight what it said and click the bookmark. We capture the text, the page, and which AI it was, and instantly show where 3 AIs agree or disagree.
On your phone, or anywhere a bookmark won't reach. Paste either the AI's answer text, or a Share link from ChatGPT / Claude / Gemini / Perplexity (we'll read the whole conversation). We run the 3-AI check instantly.
A one-click button built into Chrome, Edge, Brave, Firefox and Safari. Right-click any AI answer to check it. In the works; the bookmarklet above does the same thing today with nothing to install.
