Devil's Advocate

Devil's Advocate is a real-time voice agent that argues back. Most AI assistants are built to make things easy: you ask a simple question, relax, and wait for the answer. Devil's Advocate flips that. It puts the cognitive load on you. It takes the other side of your position, asks sharp follow-up questions, and presses exactly where your argument drifts, rests on a weak claim, or quietly dodges the question. You can't coast. You have to listen, think, and answer quickly and clearly, just as you would in a tough design review, a job interview, or an investor pitch. A round is short and focused. State a position and defend it for six minutes. Then a judge rules: win or lose, ten scores each tied to a quoted, timestamped moment, the fallacies it caught, how to improve, and a brief for the rematch. Code measures your think time and talk share; the model judges the argument, never your accent. Under the hood, DA runs on AssemblyAI Universal-Streaming behind our own low-latency orchestration: a voice detector that hears your pauses before the transcript is final, speculative replies, streaming speech synthesis, and barge-in that tracks exactly what you heard. On the same recording, AssemblyAI finalized turns in under a second, against nearly two for the alternative we tested. That is what makes real back-and-forth possible, rather than polite turn-taking. It started as a personal need: its builder is strong in logic, but live debate rewards speed, presence and conviction under pressure, and that can be trained. Where it goes next: interjecting at natural pauses, difficulty levels, rematches that build on the last verdict, and sparring on your own pitch deck or design doc. Then accounts and progress, schools and teams, and eventually a quiet meeting companion that surfaces the questions nobody asked, before they become expensive mistakes.
