Independent verification for AI-drafted work

Verify AI-drafted work, before your name goes on it.

Cachet is an independent check on AI-drafted work. It traces every citation, quote, and figure in your draft against your own sources, and says plainly what it cannot confirm. It verifies. It never writes a word.

Watch it catch a fake Check a draft

The founder

I have seen what happens when no one checks.

Madubuike Chimdindu · “Madu” · founder of Cachet

I am Nigerian. I grew up seeing what corruption does to a country, and how much can turn on whether one person is willing to check the record and stand behind it. That is my own experience, not a claim about anyone else. It is where my interest in ethics and compliance began.

I am a student at ESCP Business School, and I have spent a long time trying to understand artificial intelligence, and more than that, AI safety. The technology is still new. The law has not caught up to it, not correctly and not yet. In the meantime, people are publishing and relying on AI-generated work in which, by some measures, as much as a third of what the model produces is fabricated. Most of them do not know it.

That gap is going to close in the worst way. AI is becoming general, and it is moving into regulated environments and into ordinary daily use faster than our institutions can respond. When it does, these quiet fabrications stop being embarrassing and start doing real damage. I built Cachet so the check comes before the damage, not after.

AI is not going to wait for the rules to catch up. The least we can do is refuse to sign what we have not checked.
A word from Madu

For now it is just me, with the help of a few very special people.

The problem

AI invents citations. You sign them.

The certificate

A sealed artifact, not a badge.

See a real certificate. Every claim checked, every receipt shown, and a loud list of what it could not confirm.
