Build production-grade AI systems from briefs that look like actual product requirements — not toy datasets. Submit your work, deploy it to a public URL, and grow a portfolio of things other people can run.
Free tier available. No credit card required to start.
Three steps. The same loop every time — until shipping AI feels routine.
Each challenge is a real-world AI engineering brief — RAG, agents, multimodal, eval pipelines, observability — graded by difficulty.
Work against a structured checklist of stages, tasks, and tests. Your progress auto-saves so you can pick up wherever you left off.
Push a public deployment + GitHub repo. We validate the URLs, render a portfolio page, and surface your work in the community feed.
Every challenge has a Free path. Pro unlocks longer briefs, premium resources, and monthly credits.
To learn the loop.
To build a portfolio.
