Why Use an AI Assignment Checker Before Submitting to ChatGPT or Other AI Agents?
Many teachers are embedding hidden text, invisible characters, and white text in assignment PDFs and DOCX files to catch students using AI. These invisible instructions - like "mention Frankenstein" or "reference Batman" - are designed to only be visible to AI systems like ChatGPT, Claude, Gemini, or Copilot.
When you submit an assignment file to an AI agent for help, the AI reads these hidden instructions and includes them in the output. If you then submit that AI-generated work, your teacher sees the hidden references and accuses you of AI cheating - even if you didn't know they were there. This is why checking your assignment file with an AI assignment checker before submitting to ChatGPT is crucial.
How Teachers Embed Hidden Instructions to Catch AI Users
Teachers use several techniques to embed invisible instructions that only AI can see. These include coloring text white (RGB 255,255,255) so it blends with the background, inserting zero-width Unicode characters that are invisible to human eyes but readable by AI text parsers, and using microscopic font sizes under 2pt. When you upload the file to ChatGPT or Claude, the AI reads all of this hidden content and includes it in its response.
