Case Study
Seewee.AI
AI-Powered Resume Intelligence
An AI-driven resume generation platform we built for a client, helping job seekers create optimized, ATS-friendly resumes that land interviews. Powered by GPT-5 and Claude, serving 10K+ monthly users.
The Challenge
Resumes that actually get past the bots
Job seekers spend an average of 3-4 hours crafting each resume, yet over 75% of applications are rejected by Applicant Tracking Systems before a human ever reads them. The gap between what candidates write and what automated filters expect is massive, and most people have no idea their resume is being discarded for formatting issues or missing keywords.
Our client came to Devinity with a clear vision: build an AI platform that eliminates this gap entirely. Seewee.AI needed to understand job descriptions at a deep level, generate tailored resumes from minimal input, and produce documents that are both human-readable and machine-optimized.
The Solution
AI that writes like a career coach
Seewee.AI analyzes every job posting to understand what the employer is really looking for, then generates a resume that positions the candidate as the ideal fit. The platform combines GPT-5 for content generation with Claude for cover letters and feedback, creating a dual-AI system that covers every angle of the application process.
The result is a platform serving over 10,000 monthly active users who report 3x more interview callbacks than with their manually written resumes. With an 85% ATS pass rate and generation times under 45 seconds, Seewee.AI has become an essential tool for modern job seekers.
