AI cover letter generator
A cover letter for each company, not a template with the name swapped
Quantum Work reads the job description and your experience and writes a short cover letter that explains why you fit that role. It goes out with the application, and you can edit it anytime.
A short letter for each role, built from the job and your own experience.

A letter that reads like it was written for them
Short, specific to the company and built from your experience. A fact check cuts any sentence without a source. A follow-up email comes with it.
To the hiring team, Product Designer (remote)
Your posting asks for someone who can turn research into simple flows. In my last role I worked on the app onboarding and talked to users every week.
I work well with teams in other time zones and keep decisions written down, so nobody has to wait on me to move forward.
I would be glad to walk you through that onboarding work in a short call.

Short, specific and true
Recruiters skim. A good cover letter says in a few paragraphs what you did that matters for this job and why you want it. Ours are built from your real experience and the company's own words. Each sentence is checked against your resume and saved answers; anything without support is cut. In review mode you read it before it goes out.

Ask for changes in plain words
If a letter is not quite right, ask for what you want: shorter, more formal, more focused on a specific project. The letter is rewritten from your request, still based on your real experience.
You can also edit the text yourself, or replace it with your own letter. Whatever version you save is the one that goes out.
A simple structure that works
- Open with the role you are applying for and one line on why you fit it.
- Give one or two concrete examples from your work that match what the job asks for.
- Say why this company, in a sentence that could not be copied to another company.
- Close with a short line about next steps, like being glad to talk.
Weak opening, strong opening
A weak opening sounds like this: "I am writing to express my interest in the position advertised on your website." It uses a whole sentence and says nothing the recruiter did not already know.
A stronger one gets to the point: "I have spent four years running onboarding for B2B software customers, and your Customer Success role asks for exactly that." The years and the field have to come from your resume; the check cuts a guess. In two lines the recruiter knows who you are and why to keep reading.
Closing lines that work
End with one or two calm sentences. Thank them for reading, say you would be glad to talk about the role and sign with your full name and a way to reach you. There is no need to ask for an interview in bold words or to repeat your whole pitch.
If you work remotely from another country, the closing is a good place to repeat the hours you can cover. It answers a question the recruiter may already have.
What to leave out
Leave out your whole career story, since the resume already has it. Leave out phrases that could fit anyone, like being a hard worker or a team player. And leave out anything you cannot back up in an interview.
Our letters follow the same rules. They stay short, use your real experience and the language of the job description, and skip the stock phrases recruiters have read a thousand times.
Getting the tone right
The right tone depends on the company. A startup with a playful job post can take a lighter letter. A bank or a law firm usually expects something more formal. Read the job description and mirror its style, within reason.
If the first version feels too stiff or too casual, ask for the change. "Make it warmer" or "make it more formal" is enough. The facts stay the same. Only the way they are said changes.
Letters for remote jobs abroad
When you apply to a company in another country, the letter can do work the resume cannot. It can say where you are based and which hours you can cover, mention experience working with teams in other countries, and show that you write clearly in the language of the job.
Keep it simple and direct. A clear letter in plain English reads better than a long one full of formal phrases.
When you are changing careers
A cover letter matters more when your resume does not tell the whole story on its own. If you are moving from teaching to instructional design, or from sales to customer success, the letter is the place to connect the dots.
Name the skills that carry over and show one example of each from your real work. Keep it calm and practical. The letter does not need to apologize for the change. It only needs to show that you already do parts of the new job.
Open questions on the form
Many forms ask short questions like "Why do you want to work here?" or "Tell us about a project you are proud of." These often get read before the resume.
The robot answers them from your experience and the job description, in a few clear sentences. If you want to give a question your personal touch, edit the answer in the application before it goes out.
The follow-up email
Every application also gets a short follow-up email written for that company. If a week or so passes without an answer, it is a polite way to put your name back in front of the recruiter.
A good follow-up is three or four lines: the role you applied for, one reason you are a good fit and a thank you. Quantum Work drafts it for you, so all you do is send it when the time comes.
Questions people ask
Can I write my own cover letter instead?
Yes. You can edit any letter before it goes out, or replace it with your own text.
What tone do the letters use?
Professional and direct, without buzzwords. You can ask for changes, like shorter or more formal, and the letter is rewritten.
Do recruiters still read cover letters?
Some do and some do not, and you rarely know which one you will get. When a form asks for a letter, a short specific one is better than none, and it costs you nothing extra to have one ready.
How long should a cover letter be?
Short. Three or four paragraphs is plenty. Recruiters skim, so the first lines matter most.
Which language is the letter written in?
The language of the job. An English job gets an English letter.
Can I get a letter without the robot applying?
Yes. Paste any job description in the app and you get a standalone letter, ready to copy or download.
Will the letter mention things I did not do?
It is built not to. Each sentence is checked against your resume and saved answers, and anything without support is cut. In review mode you read it before it goes out. If you want a project mentioned, make sure it is in your resume.
Should I address the letter to a specific person?
If the job post names the hiring manager, use the name. If not, a simple "Hello" or "Dear hiring team" works fine. Guessing a name is worse than using none.
Can I reuse one letter for several jobs?
You can, but it shows. Each application in Quantum Work gets its own letter, built from that job description, so there is no reason to send the same one twice.


Every company gets its own letter.
Every application goes out with a letter written for that company, and every sentence has a source.
