With $60,000 in funding from Grad Capital, we're accelerating our work to build a new class of developer tools that reduce cognitive load and make complex codebases easier to understand.
Be in Control while AI writes Code
We are developers by profession and we solve problems that we face everyday. Every feature is designed to bring clarity, speed, and confidence to the way you read and reason about code, making large, complex codebases easier to work with.

Smart Graph
Smart Graph builds a map of your codebase in three layers. It shows your high-level parts, the specific functionalities inside them, and the actual code they use.
We know that for a tool to be truly useful, it has to earn its place in your workflow. That's why we've engineered every part of our system with a developer's core priorities in mind: security, privacy, and zero friction.
Lumyst lives inside VS Code so you never have to switch tabs or open another app. Everything happens right where you write your code.
Your codebase never leaves your machine. All heavy-duty static analysis and graph construction happen 100% locally. Only few code-snippets go to LLMs.
We send only minimal, necessary code snippets to our LLM provider, which operates under a strict zero-data retention policy. Your code is never stored or logged.
Use your own LLM API keys to ensure maximum security and full control over the AI pipeline.
We never store or access your code. Everything stays securely on your device, giving you full privacy and ownership.
Generate analysis once and share it with your team. Others can import it locally without rerunning the full analysis.
