Track your Claude usage — never hit the rate limit by surprise. Track your Claude usage so you never hit the rate limit by surprise. Claude Usage Nyan sits in your toolbar as a small orange cat. Glance at the badge to see your quota status — green is safe, yellow means watch out, orange is getting close, red is almost full. No clicking needed. Click the popup for the full picture: - Official usage data from Anthropic: 5-hour session percentage, 7-day usage, additional credits consumed, each with a reset countdown. - Real-time token tracking: input tokens, output tokens, estimated cost, and which model was used — updated as you chat. A floating status bar in the bottom-right corner of claude.ai keeps your usage visible while you work. Click the cat to collapse it. Two data pipelines run simultaneously: 1. Official — calls claude.ai's usage API every few minutes, returning the same numbers you'd see in Settings. 2. Real-time estimation — intercepts API calls on the page and accumulates token counts as responses stream back. Privacy first: - No data is collected or sent to any third party. - All data stays on your device (chrome.storage.local). - Network requests go only to claude.ai. - Fully open source — review every line of code on GitHub.

Tokenizer Live Token and Cost Monitor
Know exactly what every AI message costs — before you hit send. Tokenizer adds a small, non-intrusive overlay to your favorite AI chat interfaces. As you type, it shows a live token count, dollar cost estimate (input and output), and a running session total. No setup required — just install and start chatting. Live token counter that updates with every keystroke, so you always know the size of your prompt before sending it. Cost estimates based on current model pricing, broken down by input tokens, output tokens, and cumulative session spend. Cross-model comparison lets you see what the same prompt would cost across different AI models side by side. Word-level token breakdown with color-coded chips showing which words use the most tokens — helpful for optimizing long prompts. Energy usage estimates showing approximate watt-hours and CO2 per prompt, for users who care about the environmental impact of AI. Works with local AI tools running on localhost, including popular self-hosted setups. Everything runs 100% locally in your browser. There is no data collection, no accounts, no external servers. All token counting happens entirely on your device. Open source under the MIT License at github.com/gyeningcorp/tokenizer
