Corollary is the marketplace where anyone can build software tools with AI and earn from them. No code required. Engineers welcome.
Whether you've never written a line of code or you've written millions — Corollary gives you a way to build, share, and earn from software tools.
Describe what you need — a budget tracker, a lease explainer, a cover letter writer. The AI builds it. You use it or sell it.
Start building free →You've been laid off or gone independent. You have skills worth thousands per hour. Build the tools you'd build anyway — and sell them to thousands.
Build your first tool →Discover tools by intent. Invoke them by API. Compose workflows across the marketplace. One key, the entire ecosystem.
View Agent API →The entire pipeline — from blank canvas to paying customers — lives inside Corollary.
Type what you want to build — as simple or detailed as you like. No technical knowledge required.
The AI generates your tool instantly. Preview it live, iterate with chat, or edit the code directly.
Set your price. Hit publish. Every sale pays you directly via Stripe. Your tools work while you sleep.
Every decision in Corollary's design traces back to one principle: creators should own what they build.
Describe any tool in plain English. Claude builds it — no code required. From invoice generators to REST API clients.
Publish a tool, set your price. You keep 85 cents of every dollar. Stripe Connect pays out directly. No lock-in.
Every tool traces its lineage. Fork anything, build on it, and attribution flows back to the original creator.
Every tool is machine-readable. AI agents can discover, invoke, and compose them — the DNS layer for the agentic web.
Every dollar a user pays for your tool gets split three ways. No hidden fees. No surprise deductions. Direct to your Stripe account.
Free to start. No credit card. Build something today — and start earning the moment you publish.
