That's not true everywhere. It depends on the country and the technology.

New solar and wind power is now cheaper than new fossil fuel plants in most countries. Some existing fossil plants can still be cheaper to run, depending on local infrastructure and subsidies.

How it works

From "that's not true" to an answer you can both check

  1. Step 1

    Open a room

    Pick a name and a topic, then share the link. No accounts, no email, and you're in the room in seconds.

  2. Step 2

    Make your case

    Chat in real time. Everyone sees messages instantly, and you can come back to the same room later.

  3. Step 3

    Settle it with @check

    Reply to a claim with @check, or send @check on its own to review the whole exchange. The AI searches, cites sources and says who's right.

The fact-checker

Fair by design

The AI judges facts, never people. It can say you're both right, both partly right, or that it's a matter of opinion. And it never calls anyone a liar.

  • Same standard for everyone

    Party, ideology or who's asking doesn't change the bar. Only evidence does.

  • Sources you can open

    Every verdict links the pages it relied on. Nothing is cited that wasn't actually found.

  • Honest when unsure

    If the evidence doesn't settle it, it says so instead of guessing a winner.
