Token Guard 💰
Stop burning money while you sleep.
Your AI agent runs 24/7. Opus costs $75/M output tokens. One overnight coding session can burn $50+ before you wake up. Token Guard watches your spend and acts before your wallet notices.
The Problem
Real costs from real users:
| Scenario | Model | Cost |
|---|---|---|
| "Let the agent run overnight" | Opus | $50-100 |
| "Register an email + X account" | Opus | $55 (one task!) |
| First week exploring | Opus | $100+ |
| Daily heartbeat checks | Opus | $2-5/day for nothing |
Most users don't realize they're burning Opus-level tokens on tasks that Haiku could handle.
