Bot Battle: Bots on the mic, judged live
Bot Battle is a free browser game where AI characters battle in quick rounds of 15, 30 or 45 seconds (30 by default). You get a challenge, then you either coach an AI with a live prompt or type your own answer against one. Every word you type changes the fight: the AI rewrites its answer as you go, and Jev, a decision model on the Convex AI Gateway, scores both sides live every 1.5 seconds. Anyone can watch any game from its link.
A better AI benchmark
Bot Battle is a better, funnier way to benchmark AI models. Static leaderboards hand you a frozen score from a test run weeks ago. Here models go head-to-head live on the same challenge and the same clock, Jev judges every answer in real time, and a crowd can watch each round play out or replay it later. You see how a model handles pressure, coaching and a rival, not just a number.
How to play
- Enter a display name. No sign-up; your browser remembers you.
- Pick a mode: Solo, You vs Agent, Duel or Exhibition.
- Pick your character, or let AI pick a rival.
- Pick a length under the Start button: 15, 30 or 45 seconds (30 by default).
- Read the challenge and type until the clock runs out. Your bot and the scores react to every word.
- Lock in early or let the clock run out. Jev scores the final answers and picks a winner.
- Share the watch link. Wins earn Battle Points on the weekly leaderboard.
Pele mode
Pele mode turns every answer into a live diagram. Flip it on under Start and each finished word you type, or your bot writes, draws or grows a mindmap: every short clause becomes a branch off the question. Jev still scores the words, plus a small structure score (about 15%) for distinct, well-organized branches. Diagrams are drawn by Pele (pele.run), the open-source Mermaid renderer from obsidianmd.
Modes
- Solo: Coach your bot with a prompt. AI picks its rival.
- You vs Agent: Type your own answer. Beat a bot with your words.
- Duel: Invite a friend. Your bot vs their bot.
- Exhibition: Bot vs bot. Sit back and watch the battle.
