How to actually use this letter
Rewrite paragraph two in your own voice.
The structure of a cover letter is generic on purpose — that part you can lift verbatim. But the middle paragraph, where you map a specific win from your background to the role, is what gets you to the interview. Recruiters spot AI-generated middles immediately. Spend five minutes there.
Name something specific about the company.
Generic "I admire your mission" reads as filler. Reference a recent product launch, a value from their careers page, a public engineering post, or even a thread from their CEO. One specific reference proves you read more than the job title.
Match the tone to the company stage.
Early-stage startups (seed–Series B) reward enthusiastic and story-led tones — they're betting on motivation and slope. Larger companies (Series C+, public) reward confident and concise tones — they're betting on track record and judgment. Career changers should usually pick the career-changer tone and address the pivot in the first paragraph.
Keep it under 300 words.
Three short paragraphs. Anything longer and the recruiter skims past the part you spent time on. The cover letter is not a second resume — don't restate your bullet points. Pick one thing, write about it with detail, let your resume do the rest.
Frequently Asked Questions
How do I write a cover letter for a resume?+
A strong cover letter does three things in three short paragraphs. Paragraph one: name the role, name the company, and say in one sentence why this specific company. Paragraph two: connect one concrete win from your background to what the role needs. Paragraph three: close with what you'd want to do in the first 90 days. Skip the throat-clearing intro and the "enclosed please find my resume" closer — recruiters skim past both.
How long should a cover letter be?+
Three short paragraphs, 200–300 words total. Anything longer and the recruiter skims. Anything shorter and you look uncommitted. The cover letter is not a second resume — don't restate your bullet points. Pick one specific thing from your background that maps to the role and write about that with detail; let your resume do the rest.
Should I use AI to write my cover letter?+
AI-generated cover letters with no edits get spotted instantly — they have a very specific cadence ("I am writing to express my keen interest in...") and recruiters see hundreds. The right approach is to use a template like this one as the structural starting point, then rewrite at least the second paragraph in your own voice with a real, specific story. The structure saves you 30 minutes; your voice in paragraph two is what gets you to the interview.
Which tone should I pick?+
Match the company's voice. Early-stage startups reward enthusiastic and story-led tones. Larger or more formal companies reward confident and concise tones. Recent grads should usually go enthusiastic or story-led; career changers should go story-led or career-changer to address the pivot head-on.
Do I need a cover letter for every application?+
No, but write one anyway for roles you genuinely care about. Most postings say "cover letter optional" — which means 70% of applicants skip it. Writing a short, specific cover letter that proves you read the job description is the cheapest way to stand out, especially for senior roles where motivation matters as much as fit.
