About Caveman Mode — ChatGPT, Claude & Gemini
Caveman Mode — Make AI reply like a smart caveman
AI finally stops padding every answer with fluff 🔥
Toggle terse mode across four AI tools in one click 👊
Say goodbye to 500-word answers to 5-word questions 🪨
🚀 Why Caveman Mode?
Caveman Mode strips AI verbosity at the source — injecting a compact system prompt before every message so ChatGPT, Claude, Gemini, and DeepSeek reply in terse, fragment-friendly prose. No more hedging, no more filler, no more "Great question!" — just dense, useful answers.
🌟 Features
🪨 Three intensity levels — Choose Lite (no filler), Full (drop articles, fragments OK), or Ultra (maximum compression with causal arrows) to match your workflow
⚡ Instant keyboard toggle — Flip terse mode on or off with Alt+Shift+C without touching the popup
🔢 Live token counter — See estimated token cost per message in the composer and cumulative session usage in the on-page pill
🌐 Four-platform support — Works across ChatGPT, Claude, Gemini, and DeepSeek with site-specific selectors for reliable injection
💊 On-page indicator pill — Floating badge shows active level and session tokens; click it to toggle without opening the extension
☑️ Per-site control — Enable or disable terse mode per platform without touching global settings
🔄 Auto-reminder injection — Sends a short mode reminder on follow-up messages so AI stays terse mid-conversation
🔍 Perfect For
Developers who want code answers without the surrounding essay
Power users who send dozens of AI queries daily and hate re-reading padding
Researchers who need dense, citation-ready summaries not conversational prose
Token-budget-conscious teams monitoring API-style costs across chat sessions
Writers and analysts who use AI as a thinking tool, not a content generator
