Show HN: Context Compass – Track Claude chat token usage before hitting limit (opens in new tab)

I built a small Chrome extension for people who write long conversations in Claude and don’t want to unexpectedly hit the 200,000-token limit.

Context Compass automatically counts words and estimates token usage as you write. It updates in real time, gives you a visible percentage bar, and helps power users manage sprawling chats without losing work or flow.

I built it because I kept getting the “max context” error and realized there was no way to track usage in Claude.

No signups, no tracking, just a simple install.

Would love any feedback or ideas for improvements. Thanks!
