03 — Guide
How to write a cover letter with a free generator step by step
Pick one achievement with a number
Choose the result most relevant to the job, for example 'cut onboarding time from 10 to 4 days' or 'closed $1.2M in new ARR'. One specific number does more than three adjectives.
Find a real reason for this company
Look at the company's product, a recent launch, its mission or a value stated in the job post. 'Your focus on X' beats 'your innovative culture', which fits every company.
Generate, then edit by hand
Fill in the fields and choose a tone. Rewrite at least one sentence in your own voice, and mirror 2–3 keywords from the job description so ATS keyword matching picks them up.
Format and send
Keep it under one page (200–300 words). Paste it into the application form, or save it as a PDF named Firstname-Lastname-Cover-Letter.pdf. Address a named person when you can find one on LinkedIn.
04 — FAQ
Common questions
Do recruiters still read cover letters?
Many do, especially at small companies and for roles where communication matters. Even when a cover letter is optional, a short, specific one can set you apart from applicants who skipped it. A generic letter adds nothing.
Is it OK to use an AI or template cover letter?
Yes, as a starting point. Recruiters spot generic AI phrasing quickly ('I am thrilled to apply…', 'results-driven'). Use the generator for structure, then add specifics only you know: your numbers, your reason for this company, your voice.
How long should a cover letter be?
200–300 words in 3–4 short paragraphs, which is under one page. Recruiters often spend well under a minute on a first read, so lead with your strongest proof.
Is this cover letter generator really free?
Yes. You can generate, edit, copy and download as often as you like, with no account, no watermark and no trial. The letter is built in your browser and isn't sent anywhere.
