How I Built a Free AI Interview Prep Tool (CV Builder + Voice Training + Study Plans)

I’ve been working on a side project for the past two months – Enlist AI.

It’s a free web app that helps people get ready for job interviews. No sign‑up required during beta.

Why I built it

Getting ready for an interview is harder than most people think.

Reading articles isn’t enough – you need to practice out loud, but it’s awkward and you don’t know if you’re improving.

I wanted a tool that:

  • Builds a personalised study plan from any job description
  • Lets you train with your voice (no fake AI interviewer, just honest feedback)
  • Helps you catch filler words (“um”, “uh”) without pressure
  • Generates a CV to keep everything in one place

So I built Enlist AI.

What it does (right now, in beta)

  • CV builder – create a clean, professional CV in minutes.
  • Voice training – answer questions out loud, get feedback on clarity and fillers.
  • Study plan generator – paste a job description, get a roadmap with to‑dos and links.
  • No login required – just open the site and start using it.

Tech stack (for the curious)

  • Frontend: React + Tauri
  • Deployment: Vercel
  • Analytics: PostHog
  • AI: Groq for transcription, prompt engineering for scoring (fine‑tuning later)

Try it and help shape the future

The beta is 100% free.

If you’re job hunting or just want to practice, please give it a shot.

If you have two minutes, fill out the feedback form – you’ll get one month free when we launch.

I read every response.

Built by a 13‑year‑old founder who believes good software doesn’t need to be expensive or bloated.
