I kept getting surprised by AI bills, so I built TokenBar: a tiny Mac menu bar app that shows token usage live while you work. It is for people using Claude, Cursor, and other AI tools who want to catch cost creep before the monthly bill hits. $5 lifetime at tokenbar.site.
If you're living in Claude Code / Cursor all day, TokenBar is the tiny gut-check I wish I had earlier. It shows live token and cost pace in the Mac menu bar so you can stop runaway prompts before they become a surprise bill. $5 lifetime, no subscription: https://tokenbar.site
I built TokenBar for this exact headache. It lives in the Mac menu bar and shows live AI token spend so you can catch runaway Claude / Cursor usage before the bill lands.
