A cover letter should stay on a single page, which in practice means roughly 250 to 400 words across three or four short paragraphs. Hiring managers skim, so anything longer risks being ignored, while a few rushed lines reads as low effort. The proven structure is an opening that names the specific role and company, one or two body paragraphs that highlight relevant achievements with concrete numbers, and a brief closing that invites an interview. This tool builds exactly that shape automatically — a dated header, an opening hook, two achievement-focused body paragraphs, and a closing call to action — so your draft lands in the right length range without you counting words. Paste in your details, generate the letter, and trim or expand the editable text until it reads tightly on one page before you send it.

A resume is a structured, scannable inventory of your roles, skills, dates, and measurable results — it tells an employer what you have done. A cover letter is a short narrative that explains why those accomplishments matter for one specific job and why you want to work at that particular company. The resume is largely the same for every application; the cover letter should change each time to name the company's product, mission, or initiative and connect it to your background. Think of the resume as evidence and the cover letter as the argument that ties the evidence to the role. This tool focuses on the argument: you supply two or three achievements and a line about why the company appeals to you, and it weaves them into a tailored letter. Generate a draft, then personalize the bracketed placeholders so it complements rather than repeats your resume.

When the job posting and company site don't reveal who is hiring, "Dear Hiring Manager" is the safe, professional choice — it is neutral, widely accepted, and avoids the dated stiffness of "To Whom It May Concern." It is worth a quick search of LinkedIn or the team page first, since addressing a real person signals extra effort, but a missing name should never stop you from applying. Avoid "Dear Sir or Madam," which feels outdated and can misgender the reader. This tool defaults its salutation to "Dear Hiring Manager" and pairs it with a dated business header and the company name, giving you a correctly formatted opening out of the box. If you do find the recruiter's name, simply edit the salutation in the generated letter before you copy or download it.

Strong cover letters share three traits. First, they name something specific about the company — an actual product, initiative, or value — proving you researched the role rather than mass-mailing one file. Second, they quantify results: "grew revenue from $2M to $8M in 18 months" is far more convincing than "increased sales." Third, they read in your own voice and stay to about a page. Generic compliments and vague claims are what make most letters blend together. This tool gives you a structure built for exactly these traits, with achievement-focused body paragraphs and bracketed prompts like [specific initiative or product] that nudge you to add the concrete detail recruiters reward. The catch: you must replace every placeholder before sending, because a leftover [bracket] instantly undoes the impression of care. Generate your draft, then fill in real numbers and a genuine company-specific line to stand out.

The right tone depends on the company and the role. This tool offers three. Professional is formal and polished, the safe default that most hiring managers read as respectful rather than stiff — well suited to corporate, finance, legal, and traditional industries. Enthusiastic is warm and energetic, a better match for startups, creative roles, and culture-driven teams where personality is valued. Confident is direct and assertive, useful for competitive roles or when a strong track record can lead the conversation. Each tone rewrites the opening, the body transitions, and the closing to match, so the same details produce a noticeably different letter. If you are unsure, start with Professional; you can always regenerate in another tone and compare. Pick the tone that fits the workplace you are applying to, generate the letter, and read it aloud once to confirm it sounds like you.
