Sourcefox finds real sources for your paper
Search millions of published papers. Check if a citation is real. Copy it in APA, MLA, or Chicago. It's free, and you don't need an account.
Chatbots make up sources. Check yours.
An AI chatbot can write a citation that looks perfect and doesn't exist. The author sounds right. The journal sounds right. The paper was never published.
If that citation ends up in your paper, you're the one who has to answer for it. Paste it into the Citation Checker and you'll know in seconds.
