Documentation
Docs that both humans and AI can follow.
Specs fail when the docs are vibes. We write docs so a tired developer and a toolchain can both do the right thing.
Quick Start
Download the sai CLI binary for your platform
Install a spec from the marketplace
sai install auth-system@stableValidate your spec
sai verify ./my-specDocumentation
Getting Started
Install CLI, run your first spec, understand channels.
Spec Standard
The required files and how specmeta works.
Creating Specifications
How to draft, refine, validate, and publish.
Channels & Versioning
Stable vs canary vs pinned versions, and why buyers care.
Security & Checks
What "pass" means, and how to write checks that matter.
Artifact Types
47 types across 10 categories — from web apps to AI workflows.
The Belief
One prompt won't build great software. AI needs structure: specs, contracts, checks, and a status loop.
The Promise
Spec4AI turns AI into a reliable builder/partner by giving it clear inputs (QA), locked contracts, and checks (proof).
What we do NOT claim
- ✗“AI writes perfect code”
- ✗“One click builds your startup”
- ✗“We protect IP with magic encryption”
We sell engineering structure that makes AI output less flaky.
