Every app here already works: task managers, habit and expense trackers, flashcard and study tools. Remix one, then tell the AI Agent what to change. Ask for a login, a database, or a way to take payments, and it builds it in. Or just tell B12 the app you want to build from scratch. Start for free.
Whatever you're building, describe it here.
Websites, stores, web apps and tools, built by AI. Describe what you want and B12 builds it.
Free to try. No card needed.
