Best AI for writing a cover letter
Most AI cover letters are immediately recognizable: three paragraphs, "I am writing to express my interest," generic enthusiasm. Hiring managers see hundreds. The right model writes one that sounds human — specific to the role, the company, and your actual story.
Opus 4.7 is the best long-form writer in the catalog — it picks up tone from your prior work and matches it instead of defaulting to corporate-speak.
Sonnet 4.6 is 8x cheaper and produces 90% of the quality — start here unless the job is a stretch.
Write a cover letter for a Senior Product Designer role at a Series B fintech. About me: 8 years at Shopify, shipped the checkout redesign that lifted conversion 12%, mentor 3 designers. Make it 250 words, specific, and not generic.
What to look for in any model
- 1Reference something specific about the company that isn't on their About page
- 2Lead with the strongest 1-line story, not "I am writing to apply"
- 3Keep it under 300 words — recruiters skim
- 4Match the company's own tone (formal vs casual) from their job listing language
