Build a resume that gets past the robots — and the recruiter. ATS Resume Builder scores your CV against the exact job you're applying for, rewrites the weak lines, and writes a matching cover letter. All inside the app using AI. — REAL ATS SCORING — Paste the job description. Get a score out of 100, the keywords you're missing, what's already strong, and exactly what to fix. Not a generic checklist — your resume measured against that specific job. Most applications are filtered by software before a human ever opens them. It scans for keywords from the posting and chokes on tables, columns, text boxes and graphics. Every template here is built to pass that scan and still look like something a designer made. — AI THAT REWRITES, NOT INVENTS — Turn "responsible for sales" into a line a recruiter stops on. The AI works only from what you actually did. It will not fabricate employers, job titles, dates or degrees. Ask it to tighten a section, add metrics, or make it sound more senior, and it stays inside the truth of your own history. Tell it what to focus on, too. One line like "keep it formal" or "stress my teaching work, not the admin" steers any AI action. — WRITES IN YOUR LANGUAGE — Wrote your resume in Hindi? Your suggestions come back in Hindi. Most AI tools quietly flip you to English. This one follows your own words, in your own script. — FREE AI CREDITS — Watch a short ad, get credits, run any AI tool. No card. No subscription. No trial that expires. Prefer no ads at all? Credit packs remove them — and each pack also switches off download and resume-unlock ads for months. — IMPORT YOUR OLD RESUME — Already have a PDF? We read it and — TEMPLATES & DESIGN — • 215 CV templates and 100 cover letter designs • 30 fonts and 600+ colours • 40 header styles and 12 skill styles • Right-to-left language support • Rearrange, rename, add or hide any section • Live preview while you type • Clean, selectable-text PDF export — the kind ATS software can actually read Add exactly the sections you need: experience, education, skills, projects, certifications, licences, languages, awards, references, hobbies, or your own custom section with any name. — COVER LETTERS THAT MATCH — Same details, same design, same tone as your CV. Tell the AI the company, the role and one line on what to emphasise, and get a letter you would actually send. Matching template, so the pair looks like one application, not two documents. — BUILT FOR REAL JOB HUNTS — FRESHERS & STUDENTS No experience yet? Templates and prompts built around education, projects and skills instead of an empty work history. CAREER CHANGERS Reframe what you have already done for the job you want next, not the one you are leaving. EXPERIENCED PROFESSIONALS Keep it sharp. Lead with impact, cut the filler, and fit it on one page. APPLYING ABROAD International CV formats, RTL scripts, and a layout that survives whatever system it lands in. — YOURS, EVERYWHERE — Sign in and your profiles save to your own Google Drive or iCloud. A new phone is never a fresh start, and nobody but you can read them. Build offline. Everything except the AI works with no connection at all. — HOW IT WORKS — 1. Pick a template 2. Fill in your details, or import your old PDF 3. Score it against the job you want 4. Fix what gets flagged 5. Export a clean PDF and apply Free to use. AI is free with ads, or buy credits to skip them entirely. Questions or feedback? jayshah881994@gmail.com
