  • Keep your cover letter to one page. Aim for 250 to 400 words for the best impact.
  • Open with a strong hook that shows you understand the company and why you are a great fit.
  • Tailor each cover letter to the specific job. Mention the company name and role explicitly.

Start by selecting a template style that matches the company culture. Classic works for traditional industries, Modern for tech companies, and Elegant for creative roles. You can always switch later.

Fill in the header section with your contact details, the company name, and the recipient. Then write your opening paragraph, which should grab attention and show you understand the role. Use "Rewrite with AI" if you need help with tone.

Complete the body paragraphs by highlighting your most relevant experience and achievements. Close with a strong call to action. Preview the final result, then export as PDF or copy the text. The entire process takes most people under 10 minutes.
