Contria.

The app that argues back.

State a belief. Get the single strongest, most honest case against it.

Not to prove you wrong — to make you less sure. Contria steelmans the other side as hard as it honestly can, then hands you the verdict. No debate, no back-and-forth. One belief in, one argument out.

How it works

1

Write a belief you hold. Something you're fairly sure about — a take on work, money, politics, how to live.

2

Pick how hard to be pushed. Mild, Uncomfortable, or Brutal.

3

Read the strongest case against you. Argued in earnest, without strawmen or hedging. Then sit with it.

Three intensities

Mild

Acknowledges what's right, then raises the one strongest doubt.

Uncomfortable

Concedes your point sincerely — then dismantles it. The concession is what makes it land.

Brutal

The tightest possible case against, argued with full conviction. No easy exit.

An example

Belief — "Remote work is strictly better than working in an office."

Brutal

"Strictly better" collapses the moment you examine what actually builds careers and competence. The most valuable things you learn are never in the docs — they're the offhand correction when a senior glances at your screen, the political subtext of why a project really got killed. That's tacit knowledge, and it travels through proximity, not scheduled calls. Remote turns every learning moment into something you must explicitly request — and juniors don't know what they don't know, so they don't ask, so they don't learn. Promotions flow through trust built face-to-face; when layoffs come, the remote worker is a name on a spreadsheet. "Strictly better" means better on every axis with no tradeoff — that's not a preference, it's a blind spot…
