Auto-Fill Tool is an open-source AI assistant that reads your resume, understands job descriptions, and matches them intelligently — so you spend less time copy-pasting and more time interviewing.
It combines a resume analyzer, a job description parser, and an auto-fill engine into a single, privacy-respecting tool that runs locally in your browser.
Built for GSSoC '26 — This project is actively accepting contributions from students and first-time open-source contributors. All skill levels welcome.

| Feature | What It Does |
|---|---|
| 🔄 Real-Time Preview | Resume PDF updates instantly as you type — no refresh needed. |
| 🎨 ATS-Friendly Design | Output follows U.S. resume best practices and is tested against platforms like Greenhouse and Lever. Fonts, margins, and bullet points are handled automatically. |
| 🔒 100% Local Processing | No sign-up. No server calls. Your data never leaves your browser. The app even works offline. |
| 📥 Import Existing Resume | Drop in your current PDF and the tool extracts your data instantly, ready for editing. |
| ✅ Proven Track Record | Users have landed roles at Google, Meta, Dropbox, and more. Hiring managers have noted its clean formatting. |
| 🤖 AI Job Matching | Paste a job description and the tool highlights keyword gaps between your resume and the role. |
| ✍️ Auto-Fill Engine | Automatically populates form fields across job applications using your parsed resume data. |
The built-in resume parser lets you test how well any ATS (Applicant Tracking System) can read your resume.
Upload a PDF → get a structured breakdown of what the parser extracts. If important fields are missing, you'll know exactly what to fix.

| UI Library | React | Component-based architecture keeps the UI modular and reusable. |
| State Management | Redux Toolkit | Manages the complex, nested resume state without boilerplate. |
| CSS Framework | Tailwind CSS | Utility-first styling keeps everything in one file — no context switching. |
| Web Framework | Next.js 13 | Static site generation + file-based routing out of the box. |
| PDF Reader | PDF.js | Powers the resume parser's first step: reading raw PDF content. |
| PDF Renderer | React-pdf | Generates the downloadable resume PDF from React components. |
