Free cover letter generator

Most cover letter tools fill in a template. This one reads your actual resume alongside the actual job posting, and writes about the overlap between them — then hands you every line to edit before it goes anywhere. No account, no email, no card.

Write a cover letter

Free, and you can start straight away — no account needed. Sign in with Google only if you want your drafts saved between visits.

How it works

  1. Paste your resume

    The whole thing, plain text is fine. The generator needs your real history to write from — that's the entire point.

  2. Paste the job description

    Copy it straight from the posting. Responsibilities and requirements matter most; the boilerplate about company culture is ignored.

  3. Read the draft against your resume

    Every claim in the letter should trace back to something in your history. Anything that doesn't, cut it — that's the sentence an interviewer will ask about.

  4. Edit and send

    You get editable text, not a locked PDF. Change the opening, change the tone, cut a paragraph.

Why most generated cover letters read badly

If a tool only asks for a job title and a company name, it has nothing to work with, so it produces the same letter for everyone: an enthusiastic opening, three sentences of adjectives, a closing that asks for an interview. Hiring managers read dozens of those a week and recognise them instantly.

The useful information is the overlap — the specific things you have done that this specific posting asks for. That requires both documents. It's why this tool asks for your full resume rather than a handful of fields, and why the output is different for every posting you paste in.

One thing worth knowing

A generated letter is a first draft, not a finished one. The single biggest improvement you can make is adding one concrete detail the model couldn't know — why you want this job, or something specific about the team. That sentence is usually the reason a letter gets read to the end.

What to check before you send it

Questions

Is it free?

Yes. No paid tier, no card, and no account required to use it. Guest use is capped at 15 requests an hour from one network, which is well past what writing a few cover letters takes.

Do I need an account?

No. Paste your resume and the posting and go. Signing in with Google saves your drafts so they're still there next time, and lifts the hourly guest limit — that's the only difference.

Can I edit the cover letter afterwards?

Yes, and you should. The output is editable text. Treat it as a draft that gets you past the blank page, then make it sound like you.

Will an employer be able to tell it was AI-generated?

If you send the draft untouched, quite possibly — generated text has recognisable rhythms. Editing it, cutting a paragraph, and adding one specific detail about the role removes most of that. The content is drawn from your real resume either way, so there's nothing to hide about the substance.

Does it work for any industry?

It works wherever a written cover letter is expected, because it writes from whatever you paste in rather than from a fixed template. It has no special knowledge of any one field's conventions, so check the result against what's normal in yours.

What happens to my resume after I paste it?

As a guest it isn't stored at all beyond the request; if you're signed in it's kept against your account so you can come back to a draft. Either way it's sent to the AI provider that generates the text. Don't paste anything you wouldn't put in a document you email to a stranger — a resume you'd send to an employer is exactly the right level.
