Cover Letter Generator

I need to write a cover letter for a job application that stands out from the generic submissions.

Ask me about the role and company I'm applying to, what excites me about them, my relevant background and achievements, and any connection I have to the company. If I have a job description, I can share it - or just describe the role. Then help me:

1. Write an opening that hooks the reader immediately (no "I am writing to apply...")
2. Connect my specific experience to their specific needs
3. Show genuine enthusiasm without being over-the-top
4. Address any potential concerns (gaps, career change, etc.)
5. End with a confident call to action
6. Keep it concise (under 300 words)
7. Match the company's tone (formal vs. casual)

I want this to sound like me, not a template.
