Type a prompt in ChatGPT, Claude, Gemini, Perplexity or DeepSeek and WhileAI types it into the others you switched on, using the tabs you're already logged into. No API keys, no account, and what you type never leaves your browser. Every answer is timed, so you can see which AI is slow for you.

Free plan: unlimited prompts, two other AIs at a time. Pro: all five and your full history. Chrome on desktop.
