What a great cover letter does
It opens with a specific hook tied to the company, proves fit with one or two quantified achievements, and closes with a clear next step. Generic letters get ignored — this generator builds from your real background to stay specific.
Keep it to one page
Three to four short paragraphs is plenty. Recruiters skim, so lead with why you and why them, then back it up briefly. The draft is sized for exactly that.
Make it yours
Treat the output as a strong first draft. Add a genuine detail about the firm and your own voice before you send it.
