Cover Letter Builder

Hiring managers read cover letters quickly, so a good one has to make a case in a minute. It should say which job you want, show two or three results that match what the job needs, and explain why this company in particular. This builder asks for exactly those pieces and arranges them into a page, so you spend your time on content instead of layout.

What goes in each box

Start with your name, contact details, an optional address and a portfolio or profile link, and the date. Then name the hiring manager if you know them, the company and the role, and say where you found the job: the careers page, a referral, a recruiter. The next boxes are the case itself. “Your experience in one phrase” sets up the opening, such as “five years building web applications in React and TypeScript”. The three achievements should match the advert, one per line, with numbers where you have them. “Why this company” asks for a specific reason. Finally, you can list the skills the job asks for, tick whether you can interview at short notice and add when you can start.

How the letter is arranged

The opening paragraph names the role and the company, says where you found the job and gives your one-phrase experience. A sentence then introduces your achievements as three things you have done that match what the employer is looking for, and the list follows. If you entered skills, the next sentence says the role asks for them and that you use them every day. The company paragraph begins “I am drawn to” and gives your reason. The close offers a conversation, says you can interview at short notice if you chose that, adds your start date and thanks the reader.

Greetings and closings

British and Commonwealth convention pairs a named greeting with “Yours sincerely” and an unnamed one with “Yours faithfully”. The builder follows that: with a manager’s name you get “Dear Ms Priya Nair,” and “Yours sincerely,”, and without one “Dear Hiring Manager,” and “Yours faithfully,”. The recipient block shows the manager and the company, or “Hiring Manager” and the company.

A worked example

Press the sample. It is a letter dated 10 November 2026 from Neha Joshi to Ms Priya Nair at Brightwave Technologies for a Senior Frontend Engineer role found on the company’s careers page. She has five years of experience in React and TypeScript, and three achievements: rebuilding a checkout flow that raised completed orders by 12%, cutting the median page load from 3.1 to 2.0 seconds, and leading four people through a move to a shared component library. She mentions accessibility testing among her skills, explains that she likes the company’s focus on small shops, offers to interview at short notice and can start after a 30-day notice period. The result runs to about 210 words on one page.

Making it stronger

Write the achievements after reading the advert, and mirror its vocabulary where it is honest. Keep each bullet to one line with a verb, an action and a result. Choose a company reason that only this employer could satisfy: a product, a mission, a technical choice. Read the letter aloud, delete any sentence that could appear in another applicant’s letter, and check the company and manager names for spelling.

Limits

The builder gives structure and neat wording, not content: the quality of the letter depends on the evidence you supply, and every claim must be true because you may be asked about it. The output is a single page without letterhead graphics. It is general advice and not a guarantee of any result.
