I built a free AI resume builder focused on ATS (Applicant Tracking System) optimization. The core insight: most resumes get filtered by software before a human sees them. Pretty templates often score terribly because ATS parsers can't read them properly. ResumeForge (resumeforge.cc) shows you your ATS compatibility score in real-time as you edit. The AI generates professional summaries and optimizes bullet points for both ATS parsers and human readers. No signup required. Free to build. $7 one-time for PDF + Word download. Tech: Vanilla JS, no framework. AI for content generation. Everything runs client-side except the AI calls. Would appreciate feedback on both the product and the technical approach.
