简介
Stop guessing how much Claude you have left.
Claude Counter adds three widgets directly into the claude.ai composer — no extra tabs, no guesswork:
🔢 Token Counter — Approximate token count for your current conversation with a mini progress bar against Claude's 200k context limit. Know when you're running long before Claude starts compacting your context.
⏱️ Cache Timer — Live countdown showing how long your conversation stays cached. Cache reads are free on subscription plans, so sending a message while cached (within 5 min of the last response) costs zero credits. The timer shows your optimal window.
📊 Usage Bars — Session (5-hour) and weekly (7-day) usage bars with exact percentages and reset countdowns. More accurate than Claude's own /usage page because they use unrounded utilization fractions from Claude's live SSE stream. Bars turn red at 90% as a warning.
Why it matters: Claude subscriptions have both a 5-hour session limit and a 7-day weekly limit. Without visibility, you hit walls unexpectedly. Claude Counter makes both limits visible at a glance.
Privacy: All processing happens locally — zero external servers, zero tracking, zero data collection. Open source.
