Why Lynote Is the AI Cover Letter Checker That Actually Gets It

In Your Words

We don't alter any facts. We just check and ensure that your cover letter sounds professional. Everything else stays the same.

Identifies the Signs of AI

Fillers, predictable structure and rhythm, and even enthusiasm can reveal the letter is AI-generated. The detection tool highlights these lines so you will be able to edit them.

The detector considers word usage, sentence construction, and predictability of writing, so no single line makes the final verdict.

Detects More Than Word Replacement

Replacing a couple of words is not enough to change the style.

Tailored for Real Applications

Just copy and paste the cover letter you are going to submit.

Review, See the Results, Revise

Review your cover letter, see the scores, and then apply Humanize AI to the specific lines. Review once more for the results.
