A cover letter with a neural networkDocuments with a neural network: resumes, letters and plans

Write a cover letter with AI

A cover letter isn't a retelling of your resume — it's a couple of paragraphs on why you, specifically, and why this job, specifically. It's the first thing that gets read, and it decides whether your resume gets opened at all. An AI chat helps you write one fast and to the point — no stock "please consider my application".

What the letter needs

  • A hook. Why this company or role interests you — specifically, not "I want to grow".
  • One or two strong arguments. Relevant experience or a result that speaks directly to what the posting asks for.
  • A short call to action. Willingness to meet and talk — with no corporate boilerplate.

How to prompt the AI

Give it the job description and your resume, and ask for a letter of 4–6 sentences: "in a natural voice, tailored to this posting, with one concrete argument, no boilerplate phrases". A generic pitch turns into a letter that speaks to this specific company.

Shorter is better

A long letter doesn't get finished. If the AI hands you a wall of text, ask it to cut it in half and keep only the strongest part. A good cover letter reads in 20 seconds.

It's worth writing a fresh letter for every job posting — it takes a couple of minutes, and the result lands much better. One generic letter sent everywhere is obvious at a glance and performs worse.
