The Onboarding Problem

New engineers spend weeks just learning where things are.

Your codebase has years of decisions, patterns, and conventions embedded in it. New hires need to absorb all of this before they can contribute meaningfully. That takes time—and constant interruptions to senior engineers.

  • "Where is the authentication logic?"
  • "How does our caching layer work?"
  • "What's the pattern for adding new API endpoints?"
  • "Why is this service structured this way?"

The traditional onboarding path:

Week 1-2

Reading docs and code

Still confused about architecture

Week 3-4

Asking senior engineers questions

Interrupting productive work

Week 5-6

First meaningful PR

Finally contributing

With Lenza:

Day 1

Ask Lenza about architecture

Understand codebase structure

Day 2-3

Find implementations instantly

First PR submitted

Technical Mode

Code references and file paths included

Unlike business mode, technical responses include actual code snippets, file locations, and implementation details.

Where is the user authentication logic implemented?

Authentication is handled by Better Auth in the lib/auth.ts module.

// lib/auth.ts
export const auth = betterAuth({)
database: prismaAdapter(prisma, {...}),
session: { expiresIn: 60 * 60 * 24 * 7 },
socialProviders: { github },
})
lib/auth.ts lib/auth-client.ts 3 related files

Engineer-Focused Features

Built for how developers actually work

Semantic Code Search

Search by meaning, not just keywords. Ask 'where do we handle payments?' and find relevant code even if it's called something different.

Code Context

Answers include actual code snippets with file paths. Click through to see the full implementation in your IDE.

Architecture Understanding

Ask about how systems are structured, what patterns are used, and why certain decisions were made.

Common Questions

What engineers ask Lenza

Where is the checkout flow implemented?
How does our rate limiting work?
What's the pattern for creating new API routes?
Where are database migrations defined?
How is error handling done across the app?
What testing framework do we use?
Where is the email sending logic?
How is state management handled?
