The Problem 75% of resumes never reach a human, filtered out by ATS before recruiters see them. Manually tailoring resumes for every job is exhausting, and most people skip cover letters entirely. The result: qualified candidates get overlooked and job searches drag on for months. The Solution:...

Protailor.ai's answer:
Protailor combines AI-powered job fit analysis with instant document generation. Before spending time applying, users get a match score and gap analysis showing exactly how they align with a role. One click tailors their entire application to each specific job.
Protailor.ai's answer:
Protailor is powered by LLM models for natural, professional writing, offers multiple AI model options, and puts privacy first by never using your data to train models. The fit score feature helps users focus on roles where they have the best chances, saving time and reducing frustration.
Protailor.ai's answer:
Active job seekers who want to apply smarter, career changers who need to reframe their experience for new industries, and professionals targeting competitive roles who need every application to stand out.
Protailor.ai's answer:
While job searching, I noticed every LinkedIn posting had 150+ applicants. Despite having a strong CV and solid experience, I rarely got replies. After researching, I discovered that most recruiters now use AI-powered ATS filtering to screen candidates. If your resume isn't optimized like SEO, it never reaches human eyes. I built Protailor to solve this problem for myself, tested it, and it worked immediately. Now I'm sharing that solution with other job seekers facing the same frustration.
Protailor.ai's answer:
React, Next.js, and TypeScript for the frontend, powered by LLM's for intelligent document generation and job analysis.
