AI cover letters: useful tool, terrible final draft
AI can write a cover letter in seconds. The problem is that recruiters can tell, and a generic AI letter often hurts you more than no letter at all. The smart move is not to avoid AI but to use it for the right part of the job. Treat it as a fast first draft you must rewrite, never as the finished product.
When AI genuinely helps
AI is excellent for the parts of cover-letter writing that are mechanical or where you are stuck:
- Beating the blank page. Generate a rough structure so you have something to react to.
- Tightening wordy sentences you already wrote.
- Brainstorming three different opening angles when you cannot find one.
- Adapting one strong letter to a similar role (with heavy editing).
- Checking grammar, tone, and clarity at the end.
Used this way, AI saves time without flattening your voice.
When you must rewrite
A raw AI draft fails in predictable ways. Rewrite whenever you see these:
- Vague praise: "I am excited about your innovative company." Replace with a specific reason you want this job.
- No real proof: AI invents enthusiasm but not your achievements. Add your actual numbers and stories.
- Cliches: "team player," "passionate," "fast-paced environment." Cut them.
- Mismatched tone: AI defaults to stiff and formal. Make it sound like you.
- Repetition of the CV: a good letter adds context, it does not restate bullet points.
Things AI will get wrong
AI does not know the specifics that make a letter land. It cannot reference the hiring manager's recent post, the company's actual challenge, or the genuine reason you applied. It also hallucinates: it may state experience you do not have. Every factual claim in an AI draft must be checked against your real history.
A safe workflow
- Paste the job description and your CV into the tool.
- Ask for a draft in a specific tone.
- Delete every generic sentence.
- Add one concrete, personal reason you want the role.
- Insert two real achievements with numbers.
- Read it aloud. If it does not sound like you, fix it.
The disclosure question
You do not need to announce that you used AI, just as you would not announce using spellcheck. What matters is that the final letter is accurate, specific, and yours. If AI wrote a sentence you could not stand behind in an interview, it does not belong in the letter.
Bottom line
AI is a drafting assistant, not a ghostwriter. Use it to start and to polish, never to think for you. The letters that win are the ones with a real reason, real proof, and a real human voice, and that part is still your job.
