An AI cover letter is a cover letter written by an AI tool, typically using your resume and the job description as input.
How they work
- AI reads your resume.
- AI reads the job description.
- AI generates a tailored cover letter that highlights your matching experience and addresses the role specifically.
The good ones produce output that reads like a thoughtful human-written letter. The bad ones produce generic templates.
Best AI cover letter tools
- Sorce — auto-generated as part of every auto-applied submission. Tailored per role.
- AIApply — standalone generator with particularly polished output.
- ChatGPT / Claude — one-off generation; you write the prompt.
- JobCopilot, JobRight — auto-generate as part of their autopilot apply flows.
What to look for
- Uses both your resume and the JD as input. Either alone produces weaker output.
- Specific, not generic. Real names, projects, numbers — not "I'm passionate about your innovative culture."
- Concise. 200-300 words.
- Adapts per role. Same cover letter for 50 roles is a red flag.
When AI cover letters work
- Volume applying. 50 tailored AI cover letters in an hour beats 5 hand-written.
- Standard / mainstream roles. AI quality is high enough.
- Roles where the cover letter is a checkbox, not a writing sample.
When to write your own
- Dream role.
- Roles where the cover letter is the writing sample (consulting, writing, research).
- Cases where you have a unique story (referral, career pivot, specific connection).
