An AI cover letter generator can turn your experience and a job description into a solid first draft in seconds. Used carelessly, it produces generic letters that recruiters skim past. Here is how to get a cover letter that actually sounds like you, using your resume and the job description as inputs.

What to feed the generator

InputWhy it matters
Your current title and years of experienceFrames the opening sentence
3–6 key skills you genuinely haveLets the letter match the job's requirements honestly
1–2 achievements with numbersGives the letter evidence instead of adjectives
The full job descriptionLets the tool identify the employer's priorities and keywords
Company name and, if known, the hiring managerPersonalizes the greeting and motivation paragraph

The more specific your inputs, the less generic the output. A good generator should use only what you provide and never add qualifications you did not mention.

Step by step with the SmartJobTools generator

  1. Open the free Cover Letter Generator. No sign-up is needed.
  2. Enter your details, skills and one or two achievements from your resume.
  3. Paste the job description and add the company name.
  4. Choose a style (Professional, Short and Direct, Friendly or Formal), a length and a language: English, French, Arabic, Spanish or German.
  5. Generate, then use Make It Shorter, More Professional or More Persuasive to refine.
  6. Check the keyword panel: green keywords appear in your letter; red ones do not. Add a red keyword only if it is true for you.
  7. Edit, then copy or download as PDF or DOCX.

How to make an AI cover letter sound like you

  • Rewrite the first sentence yourself. It is the most-read line and the easiest to make personal.
  • Add one detail only you know: a product you use, a project you admire, a reason you care about the field.
  • Cut filler phrases such as "I am confident that I would be a great asset".
  • Read it aloud. If you would not say it, change it.
  • Match local conventions. UK letters use British spelling and sign-offs; see our UK cover letter format guide.

Privacy and honesty

Only paste information you are comfortable sharing, and remove sensitive details you do not need (such as your full address). Our generator sends your input securely to our AI service to produce the letter and does not store it; see our Privacy Policy. Whatever tool you use, you are responsible for every claim in the final letter.
