Does Your Cover Letter Sound Like AI Wrote It?

Most cover letters that read as AI-written were not obviously auto-generated. They are letters a real person wrote, but leaned on the same stock phrases a language model reaches for by default: language that claims a connection to the company without showing one. It is the single easiest thing a reader, human or automated, can flag, and the easiest thing to fix once you know what to look for.

What Actually Makes a Letter Sound AI-Written?

It is rarely the grammar. Grammatically correct, well-structured, and still generic is the most common failure mode. The tell is a specific family of phrases that assert fit without demonstrating it: "aligns with your values," "resonates with my experience," "makes me a strong fit for this position," "underscores the relevance of my profile." Each of these could be pasted into any cover letter for any company, for any role, and read exactly the same. That is the test: if the sentence still makes sense with the company name swapped out, it is not doing any work.

The Generic Opener Is the Biggest Tell

The first line carries the most weight, and it is also where generic phrasing shows up most often. "I am excited to apply for the [role] position at [company]" is administratively true and says nothing. A specific opener names something real: a product decision, a market position, a detail from the job description most applicants will not have read closely, or a concrete piece of your own background that maps directly onto what the role needs. If your opening line would work unchanged for a different company, it reads as generic, whether or not you wrote it yourself.

Phrases Worth Cutting

None of these are wrong, exactly. They are just interchangeable, which is the opposite of what a cover letter is for.

• "Aligns with" or "resonates with" standing in for an actual reason
• "I am confident that my skills and experience make me an ideal candidate"
• "I would welcome the opportunity to bring my expertise to your team"
• Praise for the company in the abstract, "your innovative approach," "your commitment to excellence," without naming what that approach or commitment actually is

Replace each one with the specific fact it is standing in for. If you cannot name the specific fact, that is worth noticing too: it usually means the paragraph has not earned its place in the letter yet.

How to Fix It

Read the letter and, for every sentence, ask what would break if you deleted it. If nothing changes, either cut the sentence or replace it with something specific: a number, a project, a detail about the company you actually looked up, a concrete example from your own background. Specificity is the whole fix. It does not require better writing, only a fact in place of a placeholder.

Check Yours

The fastest way to catch this in your own letter is to have someone, or something, else read it cold. A tool that flags generic openers and stock bridging phrases will catch what a careful re-read might miss, because you already know what you meant to say.
