How to use it
- Paste your letter. Paste the full cover letter, including the greeting and sign-off. Keep a blank line between paragraphs so the checker can count them the way a reader sees them.
- Add the company name. Type the company's name if you want the checker to confirm the letter mentions it. Leave it blank to skip that check.
- Read the stats. See the word, paragraph and sentence counts, the share of sentences that start with I, the Flesch reading ease score, the Flesch–Kincaid grade and the average sentence length.
- Weigh each suggestion. Each finding points to a greeting, an opening line, a long sentence or a length worth another look. Treat them as suggestions to judge against the job, not rules, and edit where the change makes the letter clearer.

Frequently asked questions
Is this cover letter checker free, and is my letter private?
Yes to both. The checker is free, needs no account and runs in your browser. Your letter is checked on your device and nothing you type leaves it, so you can check a letter that names a real employer or your own details.
What does the cover letter checker look for?
It counts words, paragraphs and sentences, and suggests a look when the letter falls outside 250 to 400 words or 3 to 5 paragraphs. It flags a greeting that names no one, such as To whom it may concern, an opening most letters share, such as I am writing to apply, more than 40 percent of sentences starting with I, and a company name you entered that the letter never uses.
How are reading ease and grade level worked out?
Both come from the length of your sentences and the number of syllables in your words. The Flesch reading ease score is higher for easier text, and the Flesch–Kincaid grade estimates the school grade a reader needs. The checker suggests a look at any sentence over 25 words and at a grade above 12.
Do I have to change everything it finds?
No. The findings are suggestions to judge, not rules. A letter of 420 words can be right for a senior role, and a long sentence can be the clearest way to say something. Use each finding as a prompt to reread that part of the letter and keep what serves the reader.
What should I use instead of a generic greeting?
Use the hiring manager's name if the job posting or company website gives it. If you cannot find a name, a greeting to the team, such as Dear Northwind Bikes hiring team, still shows you wrote the letter for this company.
