AI Tells: What Hiring Managers Spot

A growing number of students are using AI to draft cover letters. That is fine. The problem is that AI-generated letters have predictable language patterns, and hiring managers are already spotting them. The cost of a letter that reads as AI-written is high: it signals that you did not put real thought into this specific application.

This page is the audit list. Read your letter for these patterns. Rewrite the ones that appear.

Phrases AI Loves (And You Should Cut)

• "I am writing to express my strong interest in..." Default AI opener. Replace with a specific connection to the firm.
• "I am drawn to your firm's commitment to..." Common AI second-paragraph opener. Replace with a specific project of theirs that struck you, in your own words.
• "I am passionate about..." Every applicant claims to be passionate. Cut it.
• "My robust experience navigating complex challenges..." Triple AI flag: "robust," "navigating," "complex challenges." All three should go.
• "This evidence-based, holistic approach..." "Evidence-based" and "holistic" together is an AI fingerprint.
• "I would welcome the opportunity to discuss how my background aligns with..." Generic closing. Propose something specific instead.
• "In today's rapidly evolving design landscape..." "Today's" + "rapidly evolving" + "landscape" is a textbook AI sentence.
• "Demonstrating a deep commitment to..." "Demonstrating" plus "deep commitment" is rarely how a human writes.

Words That Should Send Up a Flag

Not every use of these words is an AI tell, but if more than two of them appear in your letter, do another pass:

• Genuinely, navigate, leverage, robust, comprehensive, holistic, dynamic, seamless
• Tapestry, realm, intersection (when overused), in the realm of
• Ever-evolving, transformative, groundbreaking, paradigm shift
• Storied, esteemed, prestigious
• Delve, embark on, navigate the complexities of

Patterns That Read As AI

• Triadic lists everywhere. AI loves three. "Research, design, and implementation." "Listening, analysis, and synthesis." If every sentence ends with three of something, you have a rhythm tell. Vary your sentence structure.
• Em-dashes used four or more times. AI uses em-dashes as a default rhythm device. Real human writers use them sparingly. Replace some with commas, periods, or parentheses.
• "Not just X, but Y" constructions. "Not just buildings, but communities." "Not just functional, but transformative." Reads as performative depth.
• Sentences that explain what the writer is about to do. "Let me share an example that illustrates this." Real writing just shows the example.
• Paragraph 3 that lists every skill. AI overcorrects on completeness. A real letter trusts the reader to extrapolate.

The Audit: How to Run It

1. Read your letter out loud. AI-flavored writing reads stilted out loud.
2. Search for the phrases listed above. Count how many appear. More than two is a problem.
3. Highlight every em-dash. If there are four or more, replace at least half.
4. Check paragraph openings. If three out of four paragraphs start with "I am" or "I have," vary them.
5. Ask: does any single line in this letter prove I have read this firm's work? If no line answers that, you have an AI shell with no real content.

Using AI Without Sounding Like AI

The right way to use AI for a cover letter is for structure, brainstorming, and editing. Not for drafting. A workflow that works:

• Write the first draft yourself. Even if it is rough. Your voice has to be there from the start.
• Use AI to ask questions about your draft. "What is the weakest paragraph?" "Where am I being too vague?" "Does paragraph 2 prove I have read this firm's work?"
• Use AI to suggest specific alternatives to weak phrases. "Suggest three more concrete ways to say that the firm's work integrates community engagement and ecology."
• Then write the revision yourself. Do not let AI write the prose. Let it tell you where the prose is weak.
