Comprehensive AI Authenticity Breakdown

Understanding the origin of a submission is critical. Our AI cover letter detector provides a clear, three-way percentage breakdown showing exactly how much of the text is AI-generated, human-written, or a mix of both. This granular insight gives you a reliable signal to evaluate candidate authenticity, helping you separate genuine effort from automated output.

Flexible Text And Document Uploads

Candidates submit materials in various formats, so your tools need to be adaptable. You can easily paste up to 800 words directly into the detection box for a quick check. Alternatively, upload a standard .docx, .pdf, or .txt file to analyze a single document. This flexibility ensures that no matter how you receive an application, you can verify it seamlessly.

Pinpoint Accuracy With Sentence Highlights

Reading through lengthy applications can be time-consuming. To speed up your review, the tool highlights specific sentences that appear to be generated or heavily paraphrased by AI. Instead of guessing which sections are artificial, you can immediately focus on the highlighted passages. This visual feedback makes it easier to assess the true voice of the applicant.
