Token Counter for AI Chats (T-CAC)

About

Token Counter for AI Chats (TCAC) gives you a real-time, always-visible estimate of how many tokens you've used in your current conversation prompt with ChatGPT, Claude, or Gemini.
As you type, paste, or edit your prompt, the counter updates instantly, so you always know how close you are to a model's context limit before you hit send. The session total keeps accumulating across messages. This is more a tool for focusing on prompt optimisation, and token usage. As this tool is developed we will try and add new features 

Features:
 - Real-time token estimation as you type, paste, or delete
 - Visual progress bar that shifts from green to amber to red as you approach the limit
 - Draggable HUD overlay, position it anywhere on the page
 - Lightweight and private, all calculation happens locally in your browser
 - Works across ChatGPT, Claude, and Gemini

No data is sent anywhere. No accounts, no tracking, just a simple, unobtrusive overlay that helps you manage long conversations and avoid losing context mid-task.
