What CoverSentry is
CoverSentry is a narrow checker for one document type. It scores a cover letter for signs that it was written by a model and offers suggestions, aimed at candidates who worry that mechanical phrasing will be noticed by recruiters or screening systems.
What you can do with it
- Score a cover letter before applying
- See which parts read mechanical
- Adjust tone and phrasing
- Compare drafts before sending
- Check several versions at volume
Who it is for
- Job seekers and career changers
- International students applying abroad
- Candidates sending many applications
What to watch out for
- A score is a probabilistic signal, and plain, well-structured human letters are routinely flagged
- Employers who use detectors face the same reliability problem, so a score is not a verdict about your letter
- Do not rewrite a truthful letter into generic filler just to change a score; specificity is what recruiters value
- Text you paste goes to an external service, so keep anything confidential out of it

✓ What we like
- Focused on a real, specific worry

FAQ
Does a high AI score mean rejection?
No. It is one signal from an unreliable class of tool.
Should I rewrite to lower the score?
Improve it for clarity and specificity, not to game a detector.
What is the real risk?
Generic letters, which matter far more than any score.
