TokenScope - ChatGPT Token Counter & Context Window Tracker

TokenScope is a lightweight Chrome extension that displays your current token usage and remaining context window directly inside the ChatGPT web UI.

Features:
- Live Token Counter: See how many tokens you've used and how many are left, right above the ChatGPT message input.
- Accurate Tokenization: Uses OpenAI's official tokenizer for precise token counting that exactly matches the ChatGPT API.
- Automatic Model Detection: Instantly detects which ChatGPT model you're using (including GPT-4o, GPT-4o with scheduled tasks, GPT-4.5, GPT-4o Mini, o3, o4-mini, and o4-mini-high) and adjusts the counter accordingly.
- Supports All Major Models: Works with all current ChatGPT models, including new variants as they're released.
- Visual Indicators: Color changes when approaching token limits to help you avoid hitting the maximum.
- Seamless Integration: Blends into the ChatGPT interface with a clean, user-friendly design.
