ClaudeStats

ClaudeStats gives Claude power users what's missing from claude.ai — real-time visibility into token usage, context window consumption, and plan limits, injected directly into the interface as a collapsible sidebar. WHAT IT SHOWS Plan Usage — Session %, Weekly %, and Extra usage pulled live from Claude's API, with color-coded progress bars and reset timers. Know exactly how much of your plan you've burned before you hit a wall. Context Window — Exact percentage of the 200k context window used per conversation, with automatic alerts at 90% and 95%. Never lose a long conversation to a silent limit again. Per-Message Token Counts — Precise input and output token counts sourced directly from Claude's streaming API. Not estimated — exact numbers from Anthropic's own response metadata. Session Totals — Cumulative input and output tokens across your entire session, plus message count and active model. POPUP STATS — The extension icon popup shows your full plan usage from any tab — no need to be on claude.ai to check your limits. WHO IT'S FOR Developers using Claude heavily for coding and want to track context usage per conversation. Content creators and researchers who need to stay within plan limits. Power users on Claude Pro or Team plans who want full visibility into what they're consuming. HOW IT WORKS ClaudeStats intercepts Claude's streaming API responses in your browser to extract exact token counts. Plan usage data is fetched directly from claude.ai's API using your existing browser session — no credentials required beyond your normal Claude login.
