Hi, I'm a developer from South Korea. My company uses Claude pretty heavily, and after using it for a while, I kept running into the same questions:
"How much do I have left before hitting the limit today?", "I'm paying for Max 20x but maybe 5x is enough?", "Which plan should I get for my 10 team members?"
I looked around but couldn't find a proper tool for this, so I built one myself.
I first shared it on GeekNews (kind of like HN but in Korean!), and now about 1,400 Korean users are using it. I thought it might be useful for people outside Korea too, so posting here.
What it does
You install the Chrome extension, log in once on Claude.ai, and after that it automatically collects your usage data. It also tracks Claude Code and Claude Cowork usage together.
Main features:
1. Real-time gauge bar showing 5-hour / 7-day usage rate
2. Countdown timer until next reset
3. Usage forecast — estimates your usage at reset time based on current pace
4. Browser notifications at 80% and 95% so you can slow down before hitting the limit
5. Heatmap of your usage patterns by hour
6. Plan recommendation based on 24h / 7d / 14d usage patterns
Works for teams too
Actually this is the original reason I built it. Instead of buying Claude Team plan (it's expensive!) for everyone, we give individual plans and assign Max 5x/20x based on actual usage. Saves a lot. For example, if 5 people were all on Max 20x ($200) but 3 of them actually only needed 5x ($100), that's $300/month saved. You can create an org with invite links and get per-member usage dashboards, cost optimization suggestions, and daily email reports.
Nothing fancy but!! technical stuff
The Chrome extension parses Claude.ai's internal API responses and only collects usage numbers and plan info. It does NOT collect any conversation content or prompts. The extension is MV3 based, with a Service Worker collecting data periodically in the background. Data is stored on our server and you can check everything on the web dashboard.
If you're worried about privacy — we only collect usage percentage, plan type, and reset timing. You can verify this yourself in the network tab.
