Blazing fast, dynamic token counter for input text and selections on any web page. Token Count A blazing fast, dynamic token counter for input text and selections on any web page. Are you a prompt engineer, AI enthusiast, or developer who frequently interacts with LLMs like Gemini, ChatGPT, or Claude? Have you ever lost track of how many tokens your prompt consumes before hitting submit? Token Count is the ultimate lightweight Chrome extension designed to solve this problem! It calculates and displays your token usage locally and in real-time. ✨ Key Features - Live Input Counting: Automatically adds a sleek, non-intrusive token badge right next to any text box, input field, or text area you are currently typing in. - Selection Tooltip: Highlight any text on any page to instantly see its token count in a beautiful pop-up tooltip, perfect for estimating the cost or length of articles. - Console Dashboard: Click the extension icon to access a dedicated sandbox where you can paste text and see live token and character counts. - Easy Toggling: Use the built-in toggle switch to turn the extension ON or OFF instantly across all your open tabs. - 100% Local & Private: All token estimation is done completely on your device using a highly optimized regular expression algorithm. No text is ever sent to external servers or tracked. Your privacy is fully respected. 🚀 How it works Token Count accurately estimates your tokens using an optimized heuristic for LLMs: - CJK (Chinese, Japanese, Korean) characters are counted individually. - English words and alphanumeric sequences are accurately averaged at ~4 characters per token. - Punctuation and symbols are handled intuitively. (Note: As this is an offline approximation, actual token counts may vary slightly depending on the specific model's tokenizer, such as OpenAI's tiktoken or Google's sentencepiece.) 🔒 Privacy & Permissions This extension requires: - `storage` permission: Used solely to save your preference of whether the token counter is enabled or disabled. - Host Permissions (`<all_urls>`): Used to securely inject the local token-counting script into the websites you visit so it can monitor text boxes and your text selections. We do not collect, read, or export any of your browsing data or text. Install Token Count today and never guess your prompt sizes again!
