# ThunderCV > A free, privacy-first resume builder for Indian job seekers. Resumes are built, > scored and exported entirely in the browser — no file is ever uploaded to a > server, and no sign-up is required. ThunderCV focuses on ATS (Applicant Tracking System) compatibility. Every template is tested by exporting it to PDF and re-extracting the text the way an ATS would, so headings, contact details and bullet points survive parsing. There are 19 templates covering fresher, technical, academic, creative and corporate formats. All processing is client-side: the PDF/DOCX parsing, the ATS scoring and the job-description matching run in the visitor's browser. ## Tools - [Resume builder](https://thundercv.com/editor): Fill in your details and preview a live A4 resume. Import an existing PDF, DOCX or TXT to populate it. Exports to PDF, Word or image. - [ATS checker](https://thundercv.com/ats-checker): Upload an existing resume and get a 0–100 score with 15 specific checks across contact details, section headings, quantified achievements, action verbs, length and layout.
