How to make an AI cover letter sound like you

Last updated: 4 November 2026

A cover letter has one job. It makes the reader want to open your CV. Drafts made with an AI tool often get in the way of that. They open with a formula, make big claims with nothing behind them, and sound like every other letter in the pile.

These tips keep a cover letter clear, honest and personal. They work whether you wrote the first draft yourself or had help.

Seven tips for a natural cover letter

Open with the job and one reason. Name the role and say why you are a fit in the same breath. The reader should know within ten seconds what you want.
Skip the formula opener. "I am writing to express my keen interest in..." starts thousands of letters. Say it the way you would say it to a person: "I'd like to apply for..."
Swap labels for examples. "Results-driven team player" tells the reader nothing. One real example does: what you did, with whom and what changed. Use only facts that are true.
Use the advert's words for skills, not its buzzwords. If the advert asks for "stakeholder reporting", say that you did it. Do not copy its sentences.
Keep sentences short. One idea each. If a sentence runs past about 35 words, split it. The free phrase finder lists sentences that long.
Sound like yourself. Be as formal as the field needs and no more. Read the letter out loud. If you would not say a line in an interview, change it.
Close with a next step. "I'd be glad to talk about the role this week" is better than a stack of thank-yous. One short thank-you is enough.

One more thing, before you send: check every date, employer name and job title. A rewrite can be fluent and still wrong about a fact, and no tool replaces your own read-through.

Example

We wrote this example to show the idea. It is not real HalusAI output.

I am writing to express my keen interest in the Marketing Coordinator position at Northwind, as I am confident that my skills and experience make me an ideal candidate.

Four plainer versions of that sentence:

I would like to apply for the Marketing Coordinator job at Northwind, and I think my experience fits it well.
I'm applying for the Marketing Coordinator role at Northwind because my skills and experience match the job.
Northwind's Marketing Coordinator role caught my eye, and I believe my skills and experience suit it.
My skills and experience make me a strong fit for the Marketing Coordinator position at Northwind, so I am applying.

A good letter then follows the opener with one concrete example from your own work.

Where HalusAI fits

Paste your draft letter into HalusAI and it rewrites it one sentence at a time, offering up to four versions of each sentence. You choose the one that sounds like you. It is designed to keep names, numbers and your key terms, and automatic checks reject versions that change them. No check is perfect, so read the result before you send it.

HalusAI does not write new content, so it will not add experience you did not mention. It works on English text only, and we don't promise any AI-detector result.

What it costs

US$3.99 per 10,000 words with the 3-Day Pass. Bigger passes and plans cost less per 10,000 words, down to US$1.33 on the Pro plan (billed monthly). See pricing for every pass and plan. A cover letter is short, so a run uses only a small part of the words in a pass.

Follow your institution's or workplace's AI rules. Some employers and institutions allow AI-assisted editing, some ask you to say that you used it, and some do not allow it. If you are not sure, ask before you submit.
