AI Resume Tailor — Beat the ATS Black Box

AI Resume Tailor opens the black box. Over 75% of resumes are rejected by ATS systems before a human ever sees them, and job seekers have no visibility into why. This application takes a resume and a job description, runs them through GPT-4 with structured JSON output and ATS-focused prompts, and returns a match score, missing keywords, and severity-coded suggestions — all in under 10 seconds. The product is designed around zero friction: guests get 5 free analyses with no signup. Privacy is enforced by architecture — no resume data is stored, ever. Full bilingual EN/ES support serves the underserved Latin American job market. Stripe handles the guest-to-paid conversion with embedded checkout.

Technical Highlights

• GPT-4 with strict JSON mode and low temperature (0.1) for deterministic, structured ATS analysis
• Type-safe API contract — TypeScript interfaces with union types and transformation functions
• Zero data retention by architecture — resume text is never persisted, eliminating data liability
• 5 free analyses with no signup — value delivered before asking for anything in return
• Severity-coded UI with red/amber/blue visual hierarchy mapped directly to AI output
• Embedded Stripe Checkout with post-payment account creation for seamless conversion
• Clerk webhook pipeline for automatic profile provisioning across all auth methods
• Skeleton loading states matching final render dimensions — zero layout shift
