Every developer knows the pain of hunting through files to answer simple questions like “Where is this function used?” or “How does authentication work?” I was tired of wasting hours digging through my own code. That’s when I tried something different — I turned my entire codebase into an AI-powered knowledge base using Vezlo, an open-source SDK designed to make source code understandable by AI.
What happened next changed how I work with my projects. Let’s break down how this transformation works and how you can do it too.
From Source Code to Smart Knowledge Base
Traditional code search tools match keywords. They don’t understand what your code means. Vezlo takes a new approach — it uses AST-based analysis (Abstract Syntax Trees) to understand the logic, structure, and relationships inside your codebase.
Once installed, Vezlo scans your repository and generates a semantic index — a structured, AI-ready representation of your project. It’s like giving your app a brain that actually understands its own code.
# Install Vezlo globally
npm install -g @vezlo/src-to-kb
# Generate knowledge base from your project
src-to-kb ./my-app --output ./my-kb
Ask Your Codebase Anything
Once your knowledge base is generated, you can start talking to your code. Literally.
Using Vezlo’s CLI or API, you can query your repository in plain language.
src-to-kb-search "How does authentication work?"
→ Found in: src/auth/middleware.ts
→ JWT-based authentication with refresh tokens
→ OAuth2.0 providers: Google, GitHub
No more scanning through files or Stack Overflow-style guessing. The AI understands your code contextually — not just by text matching, but by meaning.
Why This Matters for Developers and Teams
For indie devs, small teams, and SaaS founders, this means less time onboarding and more time building.
- Instant onboarding: New developers can ask “Where is the main API route defined?” and get an answer instantly.
- Smarter documentation: Vezlo auto-generates architecture summaries and function-level docs directly from your source code.
- Unified search: You can find patterns, dependencies, and relationships across multiple repositories in seconds.
It’s like having your own internal Stack Overflow — powered entirely by your own codebase.
The Bigger Vision — Product-Aware AI
Vezlo is more than just a search tool. It’s the foundation for product-aware AI assistants — bots that understand not just natural language, but your app’s structure, logic, and data flow.
Imagine having an in-house AI engineer that can explain why a function exists, how data moves through your system, and what could break if you change something. That’s the direction this is heading.
And the best part — it’s 100% open source, licensed under AGPL-3.0, and built for developers who love transparency and control.
How to Try It Yourself
Getting started takes minutes:
npm install -g @vezlo/src-to-kb
src-to-kb ./your-project --output ./kb
src-to-kb-search "How does routing work?"
✅You now have a local, semantic, AI-ready knowledge base.
✅You can query it, connect it to AI tools like Claude or Cursor, and even embed it into your internal developer assistant.
You don’t have to be an AI expert — just a developer tired of context-switching.
🧩 Final Thoughts
Turning your code into an AI knowledge base isn’t just about automation — it’s about making your own work discoverable and explainable.
Vezlo makes that future accessible right now.
If you’re building or maintaining complex SaaS products, give it a try.
You’ll never look at your repo the same way again.
