AI agents hallucinate. They generate things that aren't real, then build on top of them. Check is the engine that catches it before any of it reaches your project.
The universal anti-hallucination engine. One install. Every IDE.
Your AI generates something that doesn't exist. Then it builds the next fifty lines on top of it. Without a way to check itself against reality, one hallucination cascades into ten. Check closes the gap.
One wrong thing the AI generates becomes the foundation for the next ten things it writes. By the time you notice, the damage is layered deep. Check catches it at the source.
Prompting an AI to be more careful is probabilistic. It reduces hallucinations. It doesn't eliminate them. Check is the gate between what the AI imagines and what's real.
$0.0068 per check. One hallucination triggers retries that cost multiples of that in inference tokens. Check catches it before the cascade starts.
Check sits between your AI and your project. What isn't real gets caught. What is real passes through. You never think about it.
Check runs silently. Your AI never knows it's there. Valid work passes through without interruption. You forget it's installed until it saves you.
No delay to your workflow. Check returns a verdict before you notice it ran. Speed is not a tradeoff.
One install covers your entire environment. Claude Code, Cursor, Gemini CLI, Windsurf, Amazon Q, and more. Nothing to configure per tool.
Auto-detects your environment and configures everything. One command, one key, done.
Results vary by model, project structure, and environment. Check compares what your AI writes against what exists in your project at the moment of the check. It does not guarantee any specific outcome or detection rate. The service is provided "as is" - see our terms for details. We are working to improve our products all the time.
