# SciTools

SciTools builds software for **deep code comprehension, analysis, and onboarding**.

For over two decades, SciTools has helped developers, security teams, and organizations understand large, complex codebases — especially those that are unfamiliar, legacy, or safety-critical.

Our flagship products focus on answering hard questions about code:
- How does this system really work?
- Where are the risks, dependencies, and design boundaries?
- How can new developers become productive faster?

## What We Build

**Understand**  
A static code analysis and comprehension platform that provides rich insight into code structure, dependencies, metrics, and architecture across many programming languages.

**Onboard**  
An AI-assisted web tool designed to help developers explore and understand codebases more effectively by combining static analysis with local language models.
