Overview
The AI Cover Letter Generator allows users to upload their CV and paste any job description to instantly receive a professional, AI-generated cover letter tailored to the role, based on Stanford published research on cover letter writing. It supports multiple formats, real-time editing, further modifications by chatting with the AI, PDF/DOCX export, and a clean, responsive UI. Built entirely using free tools and infrastructure, the system is optimized for accessibility, clarity, and speed.
Challenge
The goal was to build a zero-cost platform that could handle real-time file parsing, accurate semantic matching between CVs and job descriptions, and LLM-based generation, all while looking polished and requiring no setup from users. It also needed to support rapid iteration and scalability for global usage.
Solution
I developed the entire system, frontend and backend, in under a week. Gemini 2.0 Flash powered the generation pipeline due to its no-cost and speed. The frontend was built with modern React and Tailwind, with a clean state management system and real-time editing. Document uploads, parsing, semantic conditioning, and formatting pipelines were designed to be light and reliable, allowing the platform to scale without cost.
Results
Launched within 7 days and now used daily by thousands of job seekers worldwide. The tool has helped users across industries generate tailored, high-quality cover letters with minimal effort, and continues to grow via organic reach and word of mouth.
