Make your AI honest.

AI agents hallucinate. They generate things that don't exist, then build on top of them. Check is the engine that catches it. What isn't real never reaches your project.

How we build

Built on honesty. Not probability.

Four rules. Not marketing. How everything is built.

01

Invisible.

Runs silently between your AI and your project. Your AI never knows it's there. You never think about it.

02

Instant.

Sub-100ms. No delay to your workflow. No waiting. No interruption.

03

Universal.

One install covers every AI agent and every IDE. Nothing to configure per tool.

04

Honest.

Real or not real. No scores. No confidence levels. No "maybe." Just the truth.

"It just sits there, quietly making everything honest."

How it works.

120 free checks. Honest AI starts here.

No credit card. No subscription. One install. Every IDE.
