Start the fight.
Steal the insight.

No edits. One prompt. Four AIs across one thread.

How it works

Three steps from question to stolen insight

1

Start the fight

Paste your draft, question, or idea. One prompt goes to four AIs simultaneously.

2

They fight

ChatGPT, Claude, Gemini, and Mistral challenge each other's answers. No echo chamber.

3

You steal

Jump in, @mention a specific AI, push harder. Then highlight the sharpest lines and steal them. The insights are yours to keep.

From the founders

Our son was born last year. Suddenly every question carried weight: feeding, sleep, fever, when to worry. We’d ask ChatGPT, then Claude, then Gemini. Each gave a confident answer. Each gave a different confident answer. A single AI butler isn’t trustworthy when the stakes are high.

By December we’d had enough copy-pasting and built Collider. One chat. Four AIs see each other’s answers and push back. The disagreement is the point, not a bug.

We use it almost daily now, for parenting calls and everything else.
