AI Cover Letter Detector
Check if a cover letter sounds AI-written. You get a likelihood and the reasons behind it. Free, no signup, and we do not save your letter.
Does your cover letter sound AI-written?
A cover letter is the easiest part of an application to hand to ChatGPT, so it is also where AI writing shows the most. The tools reach for the same openers and the same praise, and a hiring manager who has read 50 letters that week knows them by heart.
This checker reads your letter the way that hiring manager would. It looks for stock openers, praise that could fit any company, and claims with nothing behind them. If the result is medium or high, the reasons tell you what to change.
Phrases that make a cover letter sound AI-written
These show up in AI drafts again and again. None of them is wrong on its own. The trouble is that they could sit in anyone's letter to any company.
| Instead of | Try |
|---|---|
| Please accept this letter as my application for | Start with why this job: "Your post asks for someone who can run payroll for 40 people. I do that now." |
| I am excited to apply for this opportunity | Skip it. Show interest with a detail about the job that only a real reader would know. |
| Your company's commitment to excellence | Name one real thing: a product, a store, a client, a news story. |
| I am confident my skills make me a perfect fit | Give one example and let the reader decide. |
| Proven track record | Show the record: one result, with a number. |
| I thrive in a dynamic team environment | Say what the work is: lunch rushes, 30 calls a day, a weekly deadline. |
| I would welcome the opportunity to discuss | Ask plainly: "Can we talk this week?" |
How to make your cover letter sound like you
- Open with the reason you want this job, not with the fact that you are applying.
- Pick one or two things from past work that match the job post. Tell them with names and numbers.
- Mention one real detail about the company. If you cannot find one, say why the work itself interests you.
- Keep it under 250 words. Most hiring managers skim.
- Read it out loud. Cut any line you would not say to the person across the table.
- Use AI for a first draft if it helps. Then replace every general line with a fact from your own work.
Do employers check cover letters for AI?
Some run them through a detector. Most just read, and a stock AI letter is easy to spot next to the others in the pile. A generic letter rarely gets someone rejected on its own. But it wastes the one part of the application where you can sound like a person.
Detectors also get it wrong. A 2023 Stanford study found that popular AI text detectors flagged 61% of essays by non-native English speakers as AI-written. So a high score here does not prove anything. It means some lines read as generic, and those are worth fixing anyway.
