What it does
This tool lays out a clean one-page cover letter for you. Fill in your details, the company and the job, then write three short paragraphs. If you get stuck, press an example phrase under each paragraph and replace the [brackets] with your own facts. You see the letter as you type and can download it as Word, PDF or plain text.
The page uses a single column with standard fonts and no tables, columns or pictures, so applicant tracking systems read it cleanly. Nothing is uploaded. Build the matching resume with ATS resume builder and check how a system reads it with ATS resume checker.
How to use it
- Enter your name and contact details, then the job title, company and, if you know it, the hiring manager.
- Write the opening: the job you want and one reason you fit.
- Write the middle: one or two results that match the job ad, with numbers.
- Write the closing: thanks, a mention of your attached resume and a next step.
- Pick the closing word, paper size and font, then download.
What each setting does
- Hiring manager: becomes “Dear Alex Chen,”. Left empty, the letter says “Dear Hiring Manager,”.
- Where you saw it: fills the example phrases that mention the source.
- Example phrasing: adds a sample sentence to the paragraph, with your job and company filled in.
- Paper: US Letter or A4. Font: sans-serif or serif.
- Remember my draft: off by default. When ticked, the draft stays on this device only.
Worked example
Press Fill in an example to see a complete letter for an Operations Analyst role. It is 85 words in its paragraphs, a short sample; most real letters run 250 to 400 words.
FAQs
How long should a cover letter be? About 250 to 400 words, on one page.
Does the tool write the letter? No. It gives you a layout and example sentences you edit yourself.
Is my draft saved? Only if you tick the box, and then only in your browser.
Where the numbers come from
- The example phrasing is written by hand for fibub; no AI writes your letter. The layout is one column of plain text with standard fonts, which is what applicant tracking systems read most reliably.
