Your cover letter, in natural English.
A hiring manager should read your experience, not your grammar. ESL Humanizer fixes the phrasing that makes a strong cover letter sound translated — the wrong preposition, a missing article, a sentence structure borrowed from your first language — and leaves your experience, your tone and your voice exactly where they are.

Writing tips
5 fixes that make a cover letter sound fluent
The mistakes hiring managers notice most in cover letters by non-native writers — and what natural English looks like instead.
- 01
Applying to, not applying for
You apply for a job or apply to a company — not for apply. Writing for apply is a direct translation that doesn't work in English.
I am writing for apply to the position.
I am writing to apply for the position.
- 02
Responsible for, not responsible of
English pairs responsible with for: responsible for a task, a team, a budget.
I am responsible of the marketing budget.
I am responsible for the marketing budget.
- 03
Experience needs 'of' before a number
Five years experience is missing a word — English says five years of experience.
I have 5 years experience in sales.
I have five years of experience in sales.
- 04
Contribute to, not contribute for
You contribute to a company, a project or a team — the preposition is to, not for.
I want to contribute for your team's success.
I want to contribute to your team's success.
- 05
Show evidence instead of adjectives
Hiring managers remember numbers and outcomes. The tool won't invent achievements for you — add your own real examples.
I am a very hardworking and motivated person.
I grew our email list from 2,000 to 15,000 subscribers in eight months.
- Works only on text you wrote — it won't write your cover letter from a prompt.
- Never adds achievements, facts or ideas you didn't write.
- Keeps your level and voice — hiring managers want to hear you, not a template.
- Shows every edit so you keep only what you agree with.
Some employers and applicant-tracking processes have their own policies on AI-assisted writing. Check before you submit if you're unsure.
FAQ
Questions applicants ask
Will it write my cover letter for me?
No. It edits the English in a letter you already wrote — grammar, word choice and phrasing — without adding content, achievements or ideas that weren't in your draft.
Will it make my letter sound like a template?
It's built to do the opposite: it keeps your register, avoids inflated vocabulary and changes only what sounds unnatural, so the result still sounds like you wrote it — because you did.
How long can my cover letter be?
Free rewrites take up to 1500 characters at a time — about 250 words, roughly half a page. Subscribers can rewrite up to 3,000 characters (~500 words) at once, so a full one-page letter takes one or two passes.
Does it work for LinkedIn messages and follow-up emails too?
Yes — anything you wrote in English. The same grammar and phrasing fixes apply to outreach messages, follow-ups and thank-you notes after an interview.
