Build a properly-formatted, one-page cover letter in minutes
Add your details to begin
—
This tool builds a properly-formatted, copy-ready cover letter from a short form. It picks the right greeting, writes a strong opening that names the exact role and company, wraps your quantified achievement into a body paragraph, mirrors keywords from the job ad, closes on why you want this company, and signs off in your chosen tone. A live word-count badge enforces the one-page rule, and a checklist flags anything still missing before you export. Everything runs in your browser — no email, no account to build the letter, nothing uploaded.
Say you enter: name Jordan Smith, email jordan.smith@email.com, company Acme Corp, role Senior Marketing Manager, hiring manager Alex Rivera, 6 years of experience, current title Marketing Manager, top achievement "grew regional sales 15% in Q3 by relaunching our email program", second achievement "managed a $400K annual budget across five campaigns", skills "SEO, paid social, analytics", and the "why this company" line "I admire Acme's commitment to sustainable packaging and want to help scale that work to new markets". The tool produces the body:
Dear Alex Rivera,
I am writing to apply for the Senior Marketing Manager position
at Acme Corp. As a Marketing Manager with 6 years of experience,
I am confident I can make a meaningful contribution to your team.
In my current role, I grew regional sales 15% in Q3 by
relaunching our email program. My background spans SEO, paid
social, and analytics.
In addition, I managed a $400K annual budget across five
campaigns.
I admire Acme's commitment to sustainable packaging and want to
help scale that work to new markets. I would welcome the chance
to discuss how I can contribute to Acme Corp. Thank you for your
consideration.
Sincerely,
Jordan SmithThe badge reads "109 words — Good length" (the count covers the letter body, greeting through
closing — see below), the checklist confirms a named greeting and a quantified achievement
detected, and there are no leftover [placeholders] — so it is ready to export. Note the tool
hands you a tight, accurate draft; add a sentence or two of detail in the editable preview to flesh it out.
[add a number — e.g., 15%, $40K, 3 months] prompt rather than fabricating a statistic.The cited business-letter standard is 1-inch margins, single-spaced body, a blank line between paragraphs,
left-aligned block format, a professional 11–12pt font, and the date written out in full. A .txt
export carries the content, not the layout — apply these in your word processor, then save as PDF
(the recommended submission format).
[placeholders] so none slip into the final letter.Accuracy & privacy notes: This tool formats a letter; it does not verify the truth of any claim — every metric and statement is your responsibility. Length guidance (250–400 words, one page, 3–4 paragraphs) reflects current recruiter consensus, not a hard rule; some senior or academic roles warrant longer and many prefer shorter. A cover letter is rarely the primary ATS-parsed document, but mirroring 2–3 posting keywords still helps human reviewers — don't keyword-stuff. Everything is fully client-side: no upload, no account needed to build your letter, no email gate. Your inputs never leave your device.

Use left-aligned block format: a header with your name and contact info, the date written out in full, an optional recipient block, a greeting addressed to a named person, an opening paragraph naming the role and company, one or two body paragraphs with a quantified achievement, a closing paragraph showing why you want this company, and a sign-off with your name. Keep it to one page, 250–400 words, single-spaced with a blank line between paragraphs. This free tool assembles all of that for you.
One page — roughly 250 to 400 words across three or four short paragraphs is the current recruiter consensus. Many employers prefer shorter, and only some senior or academic roles warrant longer. This tool shows a live word-count badge so you can keep it on target before you export.
If you can find the hiring manager's name, use it (for example, "Dear Alex Rivera,"). If not, address the company's hiring team ("Dear Acme Hiring Team,") or use "Dear Hiring Manager,". Avoid "To Whom It May Concern" and "Dear Sir or Madam" — recruiters read them as low-effort, and this tool never produces them.
Yes. A quantified achievement (a percent, a dollar figure, a time saved, or a count) is the single strongest signal you can give. The tool prompts you for a metric and flags any draft whose achievement has no number, but it will never invent a statistic for you — accuracy is your responsibility.
Yes — it is 100% free and runs entirely in your browser. There is no email gate, no account required to build your letter, and nothing you type is ever uploaded. Your inputs never leave your device.
PDF is the safest submission format because it preserves your layout everywhere. This tool gives you a copy-ready plain-text letter you can paste into your word processor (apply 1-inch margins, 11–12pt font, single spacing) and export to PDF, or print straight to PDF. A .txt export carries the content but not the page layout.
