How to Catch AI Hallucinations: A Copy-Paste Hallucination Checker Prompt (Tested)

AI hallucinations present errors as confident facts, making them difficult to detect. To prevent these mistakes from becoming personal errors in professional documents, users should implement a repeatable audit step. By using a specific copy-paste fact-check prompt, users can triage and verify outputs in ChatGPT, Claude, or Gemini. This hygiene process acts like running tests before merging code, ensuring accuracy without requiring extensive research for every AI-generated response before it is utilized.
