Contra flips the usual AI dynamic: instead of helping you make your case, it takes the opposite side and pushes back hard. Pick any topic, and the AI argues against you for 6 turns. At the end, you get a score out of 100 broken down by Logic, Rhetoric, Evidence, and Originality — plus specific coaching on where your argument held up and where it didn't. There's also a 1v1 mode to debate against friends. It's a practical tool for anyone who wants to sharpen their reasoning, prep for tough conversations, or just stress-test an idea before going public with it.
