The AI writing tutor that argues back.

Prober.ai interrogates your draft with hard questions and makes you defend your reasoning — before it ever suggests a revision. Real thinking, not ghostwriting.

The Prober.ai app: your essay on the left, the Devil's Advocate challenge card on the right.

How it works

1

Write

Paste your draft or start from scratch. No judgment on grammar or polish.

2

Get Challenged

An AI persona attacks the logic of your argument — not the prose.

3

Defend & Improve

Write your own defense first. Only then does Prober unlock a concrete revision tip.

Why not just use ChatGPT?
