// What is this whole thing?
Each product has its own workspace. Start with the one that matches you today.
Sharpen core CS on a deep problem library, then test it in real-time 1v1 ranked battles, Puzzle Rush speedruns, and mock interviews.
Learn moreEducators host live algorithm quizzes, let students code right in the room, and debrief the exact concepts that need attention. Vibecoding Courses bring AI fluency onto the same syllabus.
Learn moreCompanies measure how candidates plan, prompt, verify, and ship with AI in the loop, backed by replayable evidence instead of a bare pass/fail.
Learn moreAn early agentic builder for Away From Keyboard work: orchestrate AI agents to build projects that are yours to keep, and still drop into real code whenever you want.
Learn moreIt is not four separate tools bolted together. It is one platform with one account and one shared problem library, so the same core CS you sharpen in practice shows up in ranked battles, becomes the material an educator teaches live, and is the same kind of challenge hiring teams assess with. From learning to competing to hiring, everything lives in one place instead of scattering across a new app at every stage.
Make one account and step into whichever lane fits you. Everything else is one click away.
