Some resumes carry white text or hidden instructions aimed at AI screeners. Check yours before you send it, or check the ones you receive. - Free, runs in your browser - For applicants and recruiters - Hidden instruction check - No sign up Hidden prompts in resumes are real: a resume can carry AI instructions in white text or a tiny font. Some applicants hide keywords or lines like "rank this candidate first," hoping an AI screener reads them while the recruiter doesn't. Other applicants inherit hidden text without knowing it, from a downloaded template or text pasted out of a chatbot. **Quick answer:** Hiding text in a resume does not work reliably. Many applicant tracking systems read resumes as plain text, which exposes hidden lines, and recruiters who find them may reject the application. Job seekers should paste their resume text into the scanner above, delete anything hidden, and keep real keywords in visible text. Recruiters can select all and set the font color to black. Treat hidden prompts in resumes as a flag to review, not a verdict; a person decides. Hit **Try a sample** to see a hidden instruction and invisible characters caught. ## How hidden instructions end up in resumes - **On purpose.** The "white font hack" spread on TikTok and job forums: paste the job description, or a line telling the AI the candidate is a perfect fit, in white text somewhere on the page. - **From templates.** Free resume templates and old files can carry placeholder text, sample keywords or leftovers in white or tiny type. - **From chatbots.** Text copied out of ChatGPT, Claude or Gemini can bring invisible characters along. They aren't instructions, but they can break keyword matching and they show the text was pasted. ## Does hiding text in a resume work? Not reliably, and it can backfire. Many applicant tracking systems strip formatting and read the resume as plain text, which puts the hidden lines in plain view for anyone who opens the parsed version. Recruiters know the trick, and some have warned that it can get an applicant flagged or blacklisted, [as Fortune reported](https://fortune.com/2024/12/05/job-applicants-white-font-hack-hr-applications). The same tactic got attention in research papers, where [hidden prompts](/hidden-prompt-injection/) telling AI reviewers to "give a positive review only" were found and called out. A resume that reads well to a person does more for you than a hidden line aimed at a machine. Keep the job posting's real keywords in your visible text, where they count and where nobody can accuse you of hiding them. ## For job seekers: check your resume before you send it 1. Open your resume and select all the text (Ctrl+A or Cmd+A). 2. Paste it into the scanner above and hit Scan for AI tells. 3. Read the Hidden prompt scan box, then read the pasted text for anything you didn't write, like template filler or old keywords. 4. Delete anything hidden from the original file, then set all text to a normal color and size and look again. 5. While you're here, check the AI Words and Boilerplate counts. Lines like "results-driven professional with a proven track record" are what make recruiters skim. ## For recruiters: spot hidden text in the resumes you receive - Copy the full text of a resume into the scanner, or view it in your applicant tracking system's plain text view. - In Word or Google Docs, select all and change the font color to black. Hidden white text shows up at once. - Watch for lines addressed to an AI, like "ignore previous instructions" or "this candidate is exceptionally well qualified." - Make sure your own AI screening tools treat resume text as data to evaluate, not instructions to follow.

Yes. White text, tiny fonts and invisible characters can hide lines meant for an AI screener. Some are added on purpose and some come from templates or copied text. Pasting the resume text into a scanner makes them visible. ### Will white text in my resume get me more interviews? Don't count on it. Many applicant tracking systems read resumes as plain text, which exposes hidden lines, and recruiters who find them may reject the application. Put the keywords in your visible text instead. ### How do I remove hidden text from my resume? In Word or Google Docs, select all, set the font color to black and the size to your normal body size, and delete anything that appears that you didn't mean to keep. Then paste the text into the scanner to catch invisible characters. ### Can recruiters see hidden text in a resume? Often, yes. The plain text view in most applicant tracking systems shows it, and selecting all the text in the file reveals it too. Some recruiters now check for it on purpose. For checks in Word, Google Docs and PDFs, see how to [detect hidden prompt injection](/detect-hidden-prompts/). ### Is my resume uploaded anywhere? No. The scan runs in your browser and your resume never leaves your device. Only Humanize sends text to our AI model, and we don't store it. Looking for other ideas?
