Before · AI only
Fast output. No ownership.
- Copy-paste the AI answer
- Ship without understanding
- Freeze when asked "why?"
Stop copying AI answers.
Start building real developer skills.
You can finish tasks with AI. But can you explain the solution, debug without paste, or solve the same problem alone? Prepzio measures your real skill and coaches you toward independent thinking.
Sound familiar?
AI made you faster. Did it make you better?
Most juniors use AI every day. A smaller group still cannot walk through a basic loop without help. Both can be true at once.
After · With Prepzio
Same speed. Real skill.
- Attempt first, then hints
- Explain your reasoning out loud
- See where you still lean on AI
EXPLAIN THE CODE
You shipped it. You cannot explain it.
Copilot wrote it, you accepted it, tests passed. A reviewer asks why — and your brain blanks.
DEBUG & INTERVIEW
You paste fixes. You cannot trace them live.
Something breaks → paste into AI → apply the patch. On a screen share you cannot isolate the same bug alone.
NO COMPASS
You feel productive. You are not sure you grew.
Tutorials finish. Your portfolio fills up. In the interview you freeze on the same question again.
Sample practice question · JavaScript · Junior level
Don't paste the answer. Think first.
Most tools hand you the solution. Prepzio asks you to reason first. Try a junior-level sample below — you can take a hint, but the answer is not free.
How it works
Three steps. No answers handed to you — just progress.
From sign-up to your first practice session in minutes. No tutorial maze. No “I finished the course and still freeze” feeling.
- STEP 01
Measure
A short problem. You explain. You attempt. We see how far you get before reaching for help.
~2 min - STEP 02
Practice
A few minutes a day. Hints are available; ready-made answers are not. After each session you see exactly what you missed.
5–15 min/day - STEP 03
Get independent
A short plan aimed at your weak spots. You revisit similar problems later — with less help each time.
Ongoing
Early signal
No fake user counts. Real conversations.
We're currently interviewing the first 100 AI-using junior developers to shape Prepzio.
Built from early conversations with self-taught and bootcamp juniors who use ChatGPT, Copilot, or Cursor while learning. No inflated user counts on this page, just problems we keep hearing in those calls.
“I realised I could not debug without Copilot. Scary — and true.”
“I finished the tutorials. I still freeze when they say "walk me through your solution."”
Next step
Measure your real skill. Trust yourself — not just AI.

Honest answers
Frequently asked, before you ask.
Is this another LeetCode clone?
No. LeetCode rewards finding the right answer fast. Prepzio rewards how you think: your hint usage, your reasoning, and how clearly you can explain a solution. A junior who can explain a working for-loop is more hireable than one who memorised quicksort.
Will the AI just give me answers?
It is built not to. Prepzio uses a hint ladder: direction first, then a smaller sub-problem, then a related mini example. You can always ask to see the solution, but doing so is friction-full and lowers your Independence Score over time.
How do Prepzio scores work?
Independence Score (0–100) tracks how independently you think over time; higher is better. AI Dependency Level (L1–L5) is a simpler label for the same growth ladder: L1 means you mostly copy AI answers, L5 means you can handle a fresh problem on your own. Session rubric dots (1–5 per criterion) score a single practice only; they are not your Independence Score.
Will I have to pay?
Private beta is free. We will introduce small plans once core practice loops are validated. Everyone on the waitlist gets founder pricing and an invite before launch.
When can I actually use it?
Private beta opens summer 2026. Waitlist members are invited in batches, in the order you joined. We are not chasing a public launch; we are chasing a product that genuinely moves the needle for the first cohort.
How is my data used?
Your email is used only for waitlist and beta invites. No tracking ads, no resale. Inside the app we log practice answers and hint usage to compute your scores. You can request deletion at any time. Details on the Privacy page.
