Now in Early Access

Visual, traceable reasoning for sharper ideas.

Axiom is a collaborative platform that brings precision to your thinking. Map, verify, and publish your ideas to a growing network of logically verified human knowledge.

Who decides what's true? You do. Axiom ensures arguments are valid — your premises decide what is true.

THE PARADIGM SHIFT

Announcing Axiom Early Access

When it comes to ideas, quality is more important than quantity. That's why Axiom requires every idea be proven logically valid before it is allowed to be published on the platform. Watch our announcement video to see more about that shift.

Why express ideas in code?
The exponential payoff

It's more than a technical preference; it's how Axiom guarantees transparent and precise thinking.

Higher quality contentWhen everything must logically follow, it raises the standard of discourse.
From narratives to proofProofs aren't valid because of status or rhetoric. They are valid because they are mathematically correct—and get rejected when they aren't.
EfficiencyEvery time you interact with any statement, you reap the benefits of knowing that it inherently follows from its premises. Automatic verification is not a one-time benefit—it compounds.
TransparencyWhen you are required to map out your reasoning, the incentives change. It's an opt-in paradigm shift you can't match anywhere else.
Surface hidden assumptionsTraceability allows you to examine your core assumptions so you can ask “wait, why are we assuming this premise is true in the first place?”
Richer understandingWhen the entire chain of reasoning is accessible, you can explore the precise depth of complexity that suits you.
Fixed goalpostsThe antidote to gaslighting.
Common groundAn undefined conflict cannot be effectively resolved through undefined actions or unbounded terminology. Using fixed definitions allows the problem space to be narrowed and traced to the root disagreement—the last point of common ground. It turns chaos into something we can articulate.
Unlocked complexityYou can explore far more complex logical conclusions when each logical step is proven, traceable, and fixed. With each iteration, you can choose exactly how to branch—like a fractal.

Axiom's Conclusion

When we try to solve hyper-complex global challenges using untraceable, shifty language, we hit a ceiling. Axiom lets our reasoning scale.

Axiom is currently BYOA — Bring Your Own Agent

We have first-class support for Claude, Codex, Cursor, Gemini, and Copilot.

Roadmap

We're just getting started

We're shipping new features every week as we build towards our much larger vision.

Current Phase

Early Access

Designed to get the core logic into the hands of early adopters. Expect missing features, rough edges, and the opportunity to play an important role helping shape how Axiom evolves.

Launch & Beyond

The Bigger Vision

What you see today is just the beginning; we have concrete plans for much more. When ideas are expressed in logic, the possibilities are awesome! Read more.

Public Roadmap

We're putting together a public roadmap with the specifics — what's shipping next and the concrete vision beyond early access. We will share it as soon as it's ready.

FAQ

Absolutely not. If you are comfortable expressing logical rules (e.g., "If it rains, my clothes will get wet; therefore, I need an umbrella"), you already understand logic. Axiom is designed to help you organize and refine those thoughts without needing advanced math knowledge.

Still not comfortable? No problem. Our AI skills library is designed to ask you illuminating questions that hold you to a much higher standard of thinking no matter your starting point.

While our thesis is that code is required to effectively reason through many of humanity's ongoing and upcoming issues, Axiom's integrated AI will adapt to meet you where you are and answer any questions about the Lean code you write. Even a beginner who has never heard of Lean or seen a ∀ before can absolutely still use Axiom.

Still unsure? Our Discord is full of people excited to help you learn!

Axiom uses Lean 4, one of the most popular languages for expressing math in code. By using Lean 4 as its base, Axiom benefits from the rich ecosystem of formalized concepts and all the impressive work in Lean auto-formalization.

Our goal during early access is to share this new technology as soon as possible. Therefore, users during early access will need to have some technical experience downloading and using their own AI agent.

At launch our goal is to remove much of this friction and setup. Eventually, our goal is to make Axiom a valuable product to users of all ages.

To align incentives, foster a high-integrity environment, and support Axiom's mission to build a universal world model of logically validated human knowledge.

From philosophy, policy, and morality to math, research, and conspiracy theories—the only requirement is logical validity.

While you can post about any topic, it's unlikely that you will end up making confused criticisms or hasty hot takes. Axiom is built for thoughtful discourse and higher quality reasoning.

You will need to bring your own AI agent and follow our installation guide for our CLI tool.

Yes. Your Lean files are yours, and can be exported at any time via our CLI tool and used locally completely for free.

We don't. You can absolutely have subjective premises and have subjective conclusions. We simply enforce that your logic is valid and any known contradictions are addressed.
