for all · universal quantifier · U+2200

In formal logic, ∀x, P(x) asserts that property P holds for every possible value of x. No exceptions, no conditions. We took that idea and applied it to AI agents.

Universal reliability

Works on Tuesday. Works on Friday. Works on the edge case your team forgot to test.

Formal roots

Built on logic and type theory. The same disciplines that underpin compilers, proof assistants, and formal verification.

Open to all

MIT licensed. Built in public. The universal quantifier, for the whole community.

In context

Mathematics

∀x ∈ ℝ, x² ≥ 0

For all real numbers, their square is non-negative. Proven once, holding always.

Type theory

∀T, f : T → T

A function that works for any type. Type safety as a structural guarantee.

Our product

∀ agent runs, primitives behave as specified

The LLM plans. Code executes. Every time.

∀ team, ∀ codebase, ∀ model provider: the architecture holds.
That is what we are building toward.
