Using AI to write job applications without sounding like a robot

What recruiters say they can spot

The signs recruiters commonly point to are familiar: a letter that could have been sent to any employer, an opening that praises the company in general terms, a tidy three-part sentence in every paragraph, enthusiasm that is stated rather than shown, and achievements with no detail a person could ask about.

Many of those signs appeared in weak applications long before AI tools existed. What AI changes is speed: a generic application now takes minutes to produce. A reader who has seen the same polished paragraph several times in one shortlist will notice.

The fix is the same with or without AI: specific examples from your own work, in your own words.

Using AI for structure and drafts, not for claims

AI tools are good at some parts of the job and poor at others:

• Good uses: suggesting a structure, turning rough notes into a first draft, shortening a paragraph that runs long, checking spelling and grammar, and pointing out which of the ad's requirements your draft does not address.
• Poor uses: writing your achievements, choosing your examples, or describing work you did not do. A tool that does not know what you did will fill the gap with something that sounds plausible, and you are the one who will be asked about it at interview.

Give the tool your real material: your notes on each role, the results you achieved, and the ad. Think before pasting in personal details. The Privacy Commissioner's advice to organisations is not to put personal or confidential information into a generative AI tool unless it is confirmed the information is not kept or disclosed, and the same caution makes sense for you, especially with your referees' names and contact details.

Keeping every line traceable to something you did

A useful test for any application: for each claim, could you answer "tell me more about that" in an interview? If a line says you "led a cross-functional initiative that improved efficiency by 30%", you need to know which initiative, who was involved, and where the 30% came from.

Go through an AI draft and, beside each claim, note the real example behind it. Delete anything you cannot connect to something you did, and replace vague claims with specific ones: the project, the number of people, the tool, the result. Specific detail also makes the application read as yours.

The tells: balanced clauses, flourishes, invented metrics

When you edit an AI draft, look for these and rewrite them in your own words:

• Balanced pairs and triples. "Not only X, but also Y", and lists of three adjectives in a row.
• Flourishes. Words such as "thrive", "passionate", "dynamic", "delve" and "leverage", and openings that tell the reader how excited you are.
• Invented figures. Percentages and dollar amounts you did not supply. If the tool added a number, check it or remove it.
• Overseas wording. American spellings and terms, such as "résumé" or "vacation", in an application for a New Zealand job.
• Sameness. Every paragraph the same length and shape.

Reading the draft aloud catches most of these. If a sentence is one you would never say, change it.

Checking the result against the ad

Before you send it, put the ad beside your application. Is each essential requirement covered by a real example? Does the letter name this employer and this role, and say why? Are the words the ad uses for key skills present, where they are true of you? Is it the right length, usually one page for a cover letter?
