Token Wise

Live token-cost estimates and one-click prompt rewrites for ChatGPT, Claude, Perplexity, Gemini, and Grok. Zero setup.

Token Wise shows you what your next AI prompt is about to cost, and rewrites it in one click so it costs less. A small badge appears above the prompt box on the AI sites you already use. As you type, it estimates the length of your prompt and the cost of sending it, colour-coded so you can tell at a glance whether the prompt is cheap, average, or expensive. When the cost looks high, click Optimize. Token Wise rewrites the prompt to be clearer, more specific, and shorter, and shows the original and the rewrite side by side with the estimated saving before you send. You can choose the focus of the rewrite: Balanced, Shorter, Clearer, or More specific. Supported sites Token Wise works on ChatGPT, Claude, Perplexity, Gemini, and Grok. There is nothing to configure and no API key to enter. Transparent cost estimates Every estimate is derived from each provider's own published per-token rate using a documented formula. The full methodology, including the per-model rate table and links to the provider sources, is published on the "How it works" page on our website so you can verify any number. Your prompts stay private Prompts never leave your browser unless you click Optimize. When you do, the prompt is sent over HTTPS to our hosted rewriter and is not logged or stored. A "Local only" setting keeps everything offline if you prefer. Built-in dashboard A small popup shows what you have saved today, over the last seven days, and in total. A history page keeps your last 100 optimizations and lets you export them as CSV. Everything lives in your browser. Keyboard shortcut Press Alt + Shift + O on any supported site to optimize the current prompt without leaving the keyboard.
