# Layrs (layrs.me)

> Layrs is an AI-powered Socratic tutor for system design that helps engineers learn by thinking, not memorizing.

Layrs teaches system design through guided reasoning, structured knowledge, and interactive design. It combines a Socratic AI tutor with a deep system design knowledge base.

---

## Core Capabilities

- Socratic tutoring: asks iterative, adaptive questions instead of giving direct answers
- Interactive system design canvas: visually build architectures (databases, caches, queues, APIs)
- Real-time AI feedback: evaluates decisions, tradeoffs, and scalability
- Interview simulation: FAANG-style system design and coding interviews with structured phases
- Adaptive learning: adjusts depth and expectations based on user level (SDE-1 → Staff)

---

## Learning Philosophy

Layrs follows a Socratic, thinking-first approach:

- Encourages first-principles reasoning
- Focuses on tradeoffs (latency, throughput, consistency, cost)
- Guides users through questioning rather than explanations
- Creates productive struggle to deepen understanding
- Adapts questioning style based on user expertise

Layrs is designed for active learning: users design, explain, and iterate — instead of watching or memorizing.
