How to write a cover letter for a job application
- Address a real person when you can. A name from the job ad or LinkedIn beats "Dear Hiring Manager".
- Open with the role and one concrete reason you fit it — a result, a skill, or a shared problem.
- Use the middle paragraph for one or two achievements that map directly to the job description.
- Close with a clear next step: you would welcome a conversation, and you are available to start when.
- Keep it under one page. Three to four short paragraphs is the norm.
A cover letter answers one question the resume cannot: why this job, at this company, right now. Recruiters read it after the resume has earned a second look, so it should add evidence, not repeat your work history.
A cover letter that matches your resume
The cover letter shares your name, contact details, palette, and typeface with your CV, so the two documents look like a set. Pick any of the resume templates and the letter follows it. When both are ready, Download bundle packages the resume and cover letter into a single ZIP.
Choose the closing (kind, warm, best, or sincere regards), add the recipient and company, and optionally sign the letter by typing your name in a handwriting style or drawing a signature.
Private by design
There is no server that stores your letter. The text you write stays in your browser tab, the PDF is generated locally, and nothing is sent anywhere. Use Backup .json to keep a copy you can re-import later.
Frequently asked questions
Is the cover letter builder really free?
Yes. There is no sign up, no trial, no watermark, and no limit on downloads. The whole site is free.
Do I still need a cover letter?
Often, yes. Many applications list it as optional, but a short, specific letter is one of the few ways to explain a career change, a gap, or why you want this particular company. When the application allows one, send one.
How long should a cover letter be?
Under one page — typically 250 to 400 words in three or four paragraphs. Hiring managers skim, so every sentence should give them a reason to read your resume closely.
Does the builder write the letter for me?
No. katlab.cv deliberately does not generate text with AI — recruiters increasingly spot and discount AI-written letters. It gives you the structure, layout, and PDF; the words are yours.
