A tool for practicing
critical thinking
through arguments.

State a claim. Build it into a logical argument
with premises and a conclusion. Let the system —
and others — test whether it actually holds.

Our Mission

Proposit exists to raise the quality of how people reason together. Our mission is to make rigorous thinking something anyone can practice — and to make the strength of an argument, not the standing of whoever makes it, the thing that decides what holds.

We are committed to changing what public disagreement rewards. Not confidence, volume, or speed, but the willingness to state a claim honestly, meet its strongest challenge, and change your mind when a premise doesn’t hold. When people argue this way, we reach sounder answers — and we can trust how we got there.

Most platforms reward confidence. We reward validity.

From claim to
validated argument.

01

State your claim

Pick a claim you believe. Be specific. It becomes the conclusion your argument will prove.

02

Justify your position

Add supporting premises and source references to remove doubt about your claims. Each one has to earn its place.

03

Test its validity

Others can probe your argument for counterexamples and challenge your reasoning directly — not your personality.

What makes
Proposit
different?

  • Ideas over identities

    Your argument is judged on what it says, not who said it.

  • Clarity through structure

    Organizing your thinking into premises and a conclusion reveals what you actually know — and what you're assuming.

  • Sources over soundbites

    Every premise can carry source references. Claims that hide behind "everyone knows" don't survive scrutiny.

  • Logic, not talking points

    Arguments are built from premises and conclusions. Every response must engage with the logic directly — no deflecting, no changing the subject.

Stop reacting.
Start reasoning.
