What it does

Three things, done exceptionally well.

Flags the Specific Tells

Not just 'this looks AI' — we highlight the exact phrases, sentence patterns, and cadence that give it away.

Scores the Probability

How much of this looks AI-generated? We give you a percentage you can trust.

Rewrites It Human

We don't just critique. We fix it. You get a humanized version you can copy and use.

Why it matters

If your content sounds like AI wrote it, three bad things happen.

Google's algorithm notices and ranks you lower. Readers bounce because it feels hollow. And the ones who do read it don't trust you.

The irony? The fix isn't writing less with AI. It's writing better with AI. Everything you publish should pass this test before it ships.

Built for

Who gets the most value.

Agencies publishing on behalf of clients who can't risk sounding robotic

Solopreneurs blogging with AI who want quality checks

SEO teams trying to avoid Google's AI content penalty

Anyone who's ever thought 'this sounds off, but I can't tell why'
