Letters with a single clear thesis
A cover letter is a short argument: you understand the problem they hire for and have evidence you can help. Generated scaffolding saves blank-page time; persuasion still needs your specifics.
Research depth
Reference earnings themes, product launches, or values pages you actually read. Shallow name-drops signal low effort worse than no letter.
Tone calibration
Startup casual differs from bank formal. Mirror industry register without parody—forced slang ages poorly in finance and law.
Edit before send
AI drafts may misstate job titles or company metrics. Verify every fact; unsigned typos in the hiring manager’s name end campaigns instantly.
