Yes, 100% free. Submitting your idea, voting on others, and participating in the community costs nothing. If your idea wins, the planning and prototype are also completely free.

The weekly winner receives: AI-powered analysis of their idea, a detailed planning document, and a working prototype — all built live and delivered at no cost. You also get exposure to our growing community.

If your idea wins and gets built, ewj.dev takes a 10% ownership stake in the idea and generated artifacts. This is a fair exchange: you get a free prototype worth thousands of dollars plus community exposure, and we share in the success only if your idea takes off. If you don't win, your idea remains 100% yours.

Your idea stays 100% yours — no strings attached. If you'd like to continue developing it, optional paid services are available to help you move forward. But there's no pressure or obligation.

"Your idea probably isn't as good as you think it is. If you are worried about your idea being stolen, you should never build it." - Angel Investor
Short answer: No. This website and anyone associated with this website will not use the ideas or relating artifacts without consent from the owner of the idea.
