AI Cover Letter Generator: A Tailored First Draft in Minutes

The Mira Resume AI cover letter generator writes a first draft of a cover letter from your resume and the job description you are applying to. You choose a tone, read the draft, and edit it until it sounds like you. It saves the time spent staring at a blank page, while leaving the final decisions and every fact in your hands.

In short

A good cover letter is short and specific. It explains why you want this role at this company and points to one or two things from your background that match what the employer needs. AI is good at the structure and the first pass, but it cannot know your motivation. That part, and a final read-through, has to come from you.

What the ai cover letter generator does

You provide a job description and select a resume. The generator reads both and writes a letter that references the employer's stated needs and the most relevant parts of your experience, using a standard letter structure.

You can change the tone and length, and edit any line. The goal is a draft that is close enough to finish quickly, not a letter you send without reading.

  • A tailored draft that mentions requirements from the posting and matching experience from your resume.
  • Tone options, such as professional, enthusiastic, executive or creative.
  • A clear structure: opening, evidence from your background, and a closing with next steps.
  • Editable text, so you can change wording, shorten paragraphs and add personal details.
  • A new letter for each posting, instead of one generic letter reused everywhere.

How it works

  1. Add the job description

    Paste the posting for the role. The letter will draw on its stated requirements and on the way the employer describes the work.

  2. Choose your resume

    Select the resume that reflects the experience you want to highlight, so the letter uses facts you have already checked.

  3. Pick a tone

    Choose the tone that fits the company and role. A formal industry may suit a more reserved tone than a creative startup.

  4. Generate and edit

    Read the draft and cut anything generic. Add one specific reason you want this job, and fix names, dates and details.

  5. Proofread and send

    Read it aloud, check the company and hiring manager names, and copy it into your application.

Example

Illustrative example

Inputs (shortened)

Job: Project Coordinator at a regional construction firm. Needs scheduling, vendor communication and budget tracking.

Resume highlight: Coordinated schedules for 12 events and tracked budgets in spreadsheets.

Illustrative draft opening

Dear Hiring Manager, I am writing to apply for the Project Coordinator role. In my current work I coordinate schedules and vendors and track budgets, which are the skills your posting stresses. Here is how I would bring that experience to your projects.

Edit note: add one specific reason you want to work for this company, and replace general lines with a real example.

This sample is made up to show the style. Your draft depends on the posting, your resume and the tone you pick.

What you get, and what it cannot do

What you get

  • A structured first draft tied to the posting and your resume.
  • Control over tone and length.
  • Less time on the blank page, more time on the personal parts that matter.
  • A clear reminder of what to personalize before you send.

What it cannot do

  • It cannot know why you really want the job. Add your own reason, or the letter will feel generic.
  • It may repeat resume content. Cut repetition and keep only the best one or two examples.
  • You must check names, company details and every claim. A wrong name is a common, avoidable mistake.
  • It cannot promise a reply. Some employers do not read cover letters at all.

AI output is a draft. Read it, correct it and keep only what is true. No tool, including this one, can guarantee an interview, an offer or a specific ATS result.

Who it is for

  • Applicants sending many applicationsA tailored draft per job is faster than rewriting a letter each time.
  • People who find letters hard to startA draft gives you something to react to and improve.
  • Career changersA letter is where you can explain how past experience applies to a new field.
  • Non-native English writersA clear, standard structure helps, as long as you read and adjust the tone.

Tips for better results

  • Paste the full job description so the letter can refer to the employer's own words about the role.
  • Add one sentence of your own about why you want this company or role, and put it near the top of the letter.
  • Pick one or two achievements to highlight. Letters that list everything on the resume are long and repeat what the reader already has.
  • Check the company name, the role title and the hiring manager's name. Mistakes in these are the most noticeable ones.
  • Keep the final letter to one page, and save a copy for each application so you can reuse the good parts later.

Plans and credits

Each letter costs 50 AI credits, and this tool needs the Pro plan or higher. Creating an account is free and includes 50 AI credits a month, the resume builder, resume import, PDF export and the job application tracker, but the AI tool itself is a Pro feature.

Pro is $19 a month with 1,000 AI credits, which covers up to about 20 letters a month if you use it for nothing else. Elite is $49 a month with 5,000 credits, or about 100 letters. Credits are shared across all AI tools, so your real number depends on what else you run. Current prices and details are on the pricing page.

If you prefer to write the letter yourself, the cover letter templates and examples on this site are free to copy and edit.

AI Cover Letter Generator FAQs

How does an AI cover letter generator work?

It reads the job description and your resume, finds the strongest overlap between what the employer wants and what you have done, and writes a letter in a standard structure. You then edit the draft. The result is a starting point, so you still need to personalize it and check every statement.

Will employers know I used AI?

Generic AI text can be easy to spot, with vague praise and repeated phrases. Reduce that risk by editing: add a specific reason for applying, one concrete example, and your own wording. Follow any rules in the application about AI use, and make sure everything in the letter is true.

How long should a cover letter be?

Aim for about half a page to one page, usually three or four short paragraphs. Open with the role and why you are interested, give one or two relevant examples, and close politely with next steps. Shorter is fine when you have a clear point and the employer asked for brevity.

Can I use the same letter for every job?

It is better not to. Employers can tell when a letter is generic. Keep a base structure, but change the opening, the company-specific paragraph and your examples for each role. Generating a new draft from each job description makes that tailoring faster.

Does the generator work without a resume?

The best results come from using a resume, because the letter can reference real experience. Without one, the draft would be generic. If you do not have a resume yet, build a short one first in the resume builder, then generate the letter from it.

Is the AI cover letter generator free?

A free account costs nothing, but the generator needs a paid plan and uses AI credits for each letter. The plans section on this page shows the plan and credit cost from our settings. Free cover letter templates and examples are available on the site if you prefer to write it yourself.
