Despite every "the cover letter is dead" post, recruiters still value a strong cover letter — especially for competitive roles, career switches, and any application where context matters. A well-written letter signals effort, fit, and genuine interest before a hiring manager ever opens your resume.
Personalization is the single biggest lever. A cover letter aimed at the exact company and role measurably improves interview chances compared to generic "to whom it may concern" templates. It's your chance to explain the story behind your resume — the pivot, the gap, the project you led that doesn't fit a single bullet point.
AI makes all of this fast. StackShift's AI cover letter writer turns a resume and a job description into a professional, recruiter-grade letter in seconds — so personalization stops being the reason you skip applications.
