Frequently Asked Questions
Everything you need to know about PIYE in one place.
SECTION 1 — About PIYE
Q: What is PIYE?
PIYE is an AI mentor that helps developers think clearly, plan features, debug with structure, and grow as software engineers. PIYE teaches you how to build, not just what to copy-paste.
Q: How is PIYE different from ChatGPT or Claude Code?
Chatbots give answers. PIYE gives mentorship.
- Tracks your projects
- Breaks features into steps
- Helps you learn reasoning
- Provides structured guidance
- Includes PIYE Studio learning modules
SECTION 2 — Product Usage
Q: Does PIYE write my whole project?
No. PIYE helps you understand architecture, best practices, and code design. It guides, explains, and supports — you stay in control.
Q: Who is PIYE for?
Junior devs, self-taught devs, indie builders, students, and professionals who want structure, clarity, and a reliable AI mentor.

Q: What is a “mentor session”?
One interaction inside Feature Mentor, Explain Code, Debugging, or Studio tasks. Every session is tracked so users always know their usage.
SECTION 4 — Billing & Upgrades
Q: Can I cancel anytime?
Yes. Billing is fully flexible — cancel, downgrade, or upgrade anytime.
Q: Will I lose my projects if I downgrade?
No. Your projects remain. Only limits change (sessions, memory retention, etc).
Q: How do promo codes work?
Enter your code on the pricing page → pick a plan → checkout with the discount visible.
SECTION 5 — Data, Security & Ethics
Q: Is PIYE safe?
Yes. PIYE never sells or trains models on user data. Your projects remain private.
Q: Does PIYE store my code?
Only temporarily for explanation purposes. It is never indexed or used for training.
Q: Can I use PIYE for school or work projects?
Yes — as long as your institution/employer allows AI assistance.
SECTION 6 — Roadmap & Features
Q: Will PIYE support mobile?
A native app is planned. The current web app works well on mobile.
Q: Does PIYE replace a human mentor?
No — PIYE amplifies your learning, but you remain the engineer making decisions.
🧑💻 Developer-Specific FAQ
Q: What tech stack does PIYE use?
PIYE is built with Next.js (App Router) + TypeScript, Prisma for data access, and a managed database. The UI uses Tailwind CSS + shadcn/ui with a custom PIYE theme. AI mentoring is powered by OpenAI’s API behind server-side routes.
Q: How does PIYE count “mentor sessions” technically?
Every time you trigger a mentor action (Feature Mentor, Explain Code, Debugging, Studio task), we log a usage event in the backend (e.g. mentor_session with userId, projectId, type, timestamp).
The UI shows your monthly count based on these stored events – not just API token usage – so limits are transparent and consistent.
Q: Does PIYE expose a public API?
Not yet. Right now PIYE is focused on the in-app mentor experience. A public API for integrating PIYE-style guidance into your own tools is on the long-term roadmap, but not part of the current MVP.
Q: Can I connect PIYE directly to my GitHub repo?
Today, PIYE lets you paste snippets or describe your architecture manually. Direct Git integration (reading repo structure, branches, PR context) is planned, but we’re starting with a lighter integration surface so juniors don’t have to give full repo access immediately.
Q: Does PIYE read my entire codebase?
No. You choose what to share. For Explain Code or debugging, you paste in only the parts you want help with (a file, function, or small group of files). PIYE uses that snippet plus your project context — it doesn’t automatically scan or index everything.
Q: How does PIYE handle rate limiting and OpenAI costs?
Every mentor session goes through a server-side rate limiter and is associated with the user’s plan. We track estimated token usage per request and enforce plan-appropriate ceilings (e.g. Starter vs Pro). This keeps OpenAI usage under control while still feeling responsive for users.
Q: Is PIYE opinionated about stack (e.g. Next.js vs Laravel)?
PIYE has strong patterns for modern web stacks (Next.js, React, TypeScript, Node, REST/JSON APIs), but the patterns are transferable. The mentor focuses on architecture, separation of concerns, and reasoning, not just one framework.
Q: Can I use PIYE to learn how to structure real SaaS apps?
Yes – that’s a core goal. PIYE helps you:
- Break features into milestones and steps
- Think about data models, API boundaries, and components
- Understand trade-offs instead of blindly generating code
PIYE Studio modules go deep on prompting as an engineer, feature planning, and debugging workflows you can reuse across projects.
Q: Will PIYE ever become a full “AI IDE” like cursor/Claude Code?
PIYE is not trying to replace your editor. Instead, it focuses on the layer above your IDE: planning, architecture, learning, and structured guidance. You still use VS Code / Cursor / WebStorm to write code; PIYE sits beside you as the calm senior dev in your corner.
