A Chrome extension that converts typing speed from Words Per Minute (WPM) to Tokens Per Second (TPS), helping you visualize your typing speed in terms of LLM output.

Ever wondered how your typing speed compares to AI models like Claude or GPT? This extension bridges that gap by converting traditional WPM measurements into TPS, the standard metric for LLM token generation.

Language models output text in tokens per second (TPS), not words per minute. By converting your typing speed to TPS, you can:

• Compare your speed directly to AI models
• Understand performance benchmarks in AI terms
• See typing speed from a modern, AI-centric perspective

Average tokens per word: ~1.3
TPS = (WPM / 60) × 1.3
TPS ≈ WPM × 0.02167

Example conversions:

• 60 WPM → 1.30 TPS (baseline typist)
• 100 WPM → 2.17 TPS (proficient typist)
• 140 WPM → 3.03 TPS (professional typist)
• 200 WPM → 4.33 TPS (elite typist)

For context: Claude Sonnet 3.5 can generate 80-100+ TPS, while GPT-4 generates 30-50 TPS.

• Nitro Type (nitrotype.com)

1. Download or clone this repository
2. Open Chrome and go to chrome://extensions/
3. Enable Developer mode (toggle in top-right corner)
4. Click Load unpacked and select the chrome-tokensec directory
5. Visit nitrotype.com to see it in action

Visit Nitro Type and the extension automatically converts all WPM values to TPS in real-time. Converted values appear in light green.

Works on:

• Stats page (average speed, highest record, summary tables)
• Race results (your speed, opponent speeds, earnings)
• Live race dashboard (real-time conversion as you type)
