Guidy is a full-stack, paid AI platform built to solve one of the most stressful parts of a job search: figuring out whether your résumé is actually good enough, and preparing to perform under interview pressure. Rather than a single-purpose tool, Guidy bundles the whole pre-interview journey — résumé generation, résumé scoring, interview practice, and career direction — into one subscription product.
The Problem
Most job seekers have no reliable way to know if their résumé will actually pass an ATS (Applicant Tracking System) filter or catch a recruiter's eye in the first six seconds. Generic résumé templates don't adapt to the role being applied for, and interview prep is usually limited to generic question lists with no real feedback loop.
The Solution
Guidy was built as an end-to-end AI product covering four core capabilities:
- AI Résumé Generation — builds ATS-optimized résumés tailored to the target job description, not just a generic template.
- CV Heatmap Analysis — an AI-driven visual heatmap that scores and highlights which sections of a résumé draw attention (or get skipped), so users know exactly what to fix.
- AI Mock Interviews — simulated interview sessions that adapt questions to the candidate's target role and give structured feedback.
- AI Career Guidance — personalized career-path recommendations based on the user's background, skills, and goals.
Engineering Highlights
The platform runs on Next.js for the front end and API routes, with PostgreSQL handling user data, résumé versions, and interview history. AI features — résumé generation, heatmap scoring, and interview simulation — are powered by OpenAI models, orchestrated through custom prompt pipelines tuned specifically for résumé and interview contexts rather than generic chat. Stripe handles subscription billing end-to-end, and the whole interface is styled with Tailwind CSS for a fast, consistent, and mobile-responsive experience.
Outcome
Guidy is live in production at guidy.space, running as a real paid product rather than a prototype — handling live users, live billing, and live AI workloads end-to-end.
