Pro costs $20/month. Max costs up to $200. But Claude Code gives you almost no visibility into how you're using it — so you can't tell if you're getting the full value of what you're paying for.
You hit the wall mid-task with no warning. No countdown, no percentage — just "please wait." No way to pace yourself or plan around resets.
Sessions fill with stale file reads and old tool results. By the time quality drops, you've burned tokens on degraded responses you'll redo.
Millions of tokens flow through your sessions. Without the numbers, you can't tell if your tier is right or where your budget goes.
One click on the menu bar icon. Everything you need to use Claude Code efficiently, in a native macOS popover.
See your 5-hour burst and 7-day sustained usage at a glance. Utilization percentage, reset countdowns, and time-to-limit predictions so you can pace your work.
Track your 5 most recent sessions with live context fullness. Smart warnings for long conversations, bloated input, and rapid token consumption.
Per-model breakdown: input, output, cache read, and cache write. Toggle API cost estimates to see what your usage would cost at pay-per-token rates.
Sparkline charts across 24 hours, 7 days, and 12 months. Today's stats with trend arrows, projections, and your all-time busiest day.
Get notified on Anthropic outages and when your usage crosses a threshold you set. Plan around limits instead of being surprised.
Support for 2 Claude accounts with one-click switching. Perfect for separate personal and work orgs — each with its own limits and stats.
Claude can hold ~200K tokens in memory per session — think of it as a notepad. Every message you send, every file Claude reads, every response it gives goes on that notepad. Nothing gets erased between turns. Once the notepad is full, Claude Code auto-compacts: it summarizes everything into a few paragraphs and throws the rest away. That summary is lossy — specific file contents, exact instructions, and nuanced decisions get compressed into a brief recap. Claude continues working, but it's now working from a summary instead of the real thing.
