AI can help you get past the blank page, but a weak prompt creates a bland cover letter. The goal is not to avoid AI entirely; it is to give the tool enough real material that the draft sounds specific to you and the role.
Does this affect you?
Use this with ChatGPT, Gemini, Claude, or another AI chat tool when writing a job application cover letter on web or mobile.
Get a strong first draft
The output depends on what you provide. Gather the details first.
- Open your AI chat tool.
- Paste the full job posting, not just the job title.
- Paste your resume text or a summary of relevant experience, including real numbers and achievements where you have them.
- Add a prompt such as: Using this job posting and my resume, write a cover letter under 300 words. Focus on my experience with this specific skill and avoid generic phrases.
- Review the draft as a starting point, not a finished letter.
Edit it so it does not sound AI-written
This is the step that makes the letter usable.
- Cut generic openings such as I am writing to express my interest. Replace them with a specific connection to the role or company.
- Remove overused AI filler words and phrases such as delve, leverage, furthermore, robust, seamless, and proven track record when they do not sound like you.
- Add one detail only you would know: a real project, a measurable result, a company-specific reason, or a direct connection to the role.
- Read the letter out loud and rewrite any sentence you would never actually say.
- Ask for one focused revision, such as shorten this to three paragraphs or make the tone more direct, instead of a vague improve this.
More control
Match the company tone
Paste a short paragraph from the company website or job posting and ask for a similar tone. A formal law firm and a casual startup should not receive the same letter.
Reuse a letter you already like
If you have a strong prior cover letter, paste it with the new job posting and ask AI to adapt the structure and emphasis for the new role.
Personal editing lowers risk
Some hiring workflows look for AI-generated writing. More importantly, recruiters notice generic AI phrasing. Thorough editing makes the letter better and less machine-flavored.
Keep every claim true
Do not let AI add skills, titles, numbers, or achievements you cannot explain in an interview. Use it to phrase your experience, not invent it.
