Most resumes never reach a human. ATS software filters them out automatically — usually for missing a few keywords from the job description. The applicant never finds out why. DeckdOut is a Chrome extension that reads the job listing and tells you your match score, missing keywords, and what to fix — in 10 seconds. Plus a tailored cover letter, ATS-optimised resume, and interview prep built from the actual JD. Works on 17+ job boards. Free: 3 analyses/week, no credit card.
