AI-native language

Synth

An AI-native language: human-readable source with annotations an agent can actually use — specs, intent, and demos that earn their keep.

What it is

Synth sits in the awkward, interesting middle: code that people can read, and structure that language models can follow. Annotations carry intent and contracts; the compiler and tooling turn that into something you can run and check.

Why I built it

Most “AI coding” piles prompts onto languages that never expected a co-pilot. I wanted a place where agent workflows are a first-class concern — not a bolt-on chat window.
