Writing tips

5 fixes that make a motivation letter sound fluent

The mistakes reviewers notice most in letters by non-native writers — and what natural English looks like instead.

  1. 01

    Interested, not interesting

    Describe your own feelings with -ed adjectives: you are interested in a field. Interesting describes the thing itself.

    I am interesting in public health.

    I am interested in public health.

  2. 02

    Present perfect for experience that continues

    With since and for, English usually needs the present perfect when the experience continues today.

    I study English since 2019.

    I have studied English since 2019.

  3. 03

    Don't drop a, an and the

    Singular countable nouns need an article: a great opportunity, a scholarship, the program.

    It will give me big opportunity.

    It will give me a great opportunity.

  4. 04

    Avoid word-for-word translations

    Research is uncountable, and English says conduct or do research, not make a research.

    I made a research about water pollution.

    I conducted research on water pollution.

  5. 05

    Show evidence instead of adjectives

    Committees remember specifics. The tool won't invent achievements for you — add your own real examples.

    I am a very hardworking and responsible person.

    I coordinated a 12-person volunteer project while working part-time.

How it works

A proofreader, not a ghostwriter

Liang et al., Patterns (2023) ↗
  • Works only on text you wrote — it won't write your letter from a prompt.
  • Never adds achievements, facts or ideas you didn't write.
  • Keeps your level and voice — reviewers want to hear you, not a template.
  • Shows every edit so you keep only what you agree with.

Some programs set rules on AI-assisted editing. Check your application's guidelines before you submit.

FAQ

Questions applicants ask

Can I use an editing tool for a scholarship application?

Rules differ by program. Many accept proofreading help but not having someone — or an AI — write the letter for you. ESL Humanizer only edits text you wrote, but always check the guidelines of the program you're applying to.

Does it work for Chevening, DAAD, Erasmus Mundus or Fulbright letters?

Yes — it works on any letter written in English, whatever the scholarship. It doesn't know a program's specific requirements, so follow the official instructions on length and content.

How long can my letter be?

Free rewrites take up to 500 characters at a time — about a paragraph. Subscribers can rewrite up to 3,000 characters (~500 words) at once, so a one-page letter takes one or two passes.

Will it make my letter sound like AI wrote it?

It's built to do the opposite of generic AI polish: it keeps your register, avoids inflated vocabulary and changes only what sounds unnatural. No tool can guarantee how a reader or a detector will judge a text, so read the result and keep what sounds like you.
