Caveman Mode adds a short instruction to each message you send on ChatGPT, Claude & Gemini, so replies stay compact.

Caveman Mode turns on the viral Caveman language for AI, no-filler replies across ChatGPT, Claude, and Gemini. When it's on, it quietly prepends a short "speak caveman" instruction to your message, the model drops the articles, hedging, and pleasantries but keeps every bit of technical substance, with code, commands, and error strings left verbatim. • One toggle, three sites — ChatGPT, Claude, Gemini. • Three intensities — lite, full, ultra. • Per-site control and a one-click on-page pill. • No account, no API key, nothing sent off your device. Say "stop caveman" in any chat to drop it for that thread. From the team behind the open-source caveman toolkit.
