Your AI bill isn't one number. It's thousands of users, each costing you differently. Tozil shows you exactly where your money goes — and how to cut it in half.
2 lines of code. Async. Never on your critical path.
| User | Cost | Trend |
|---|---|---|
| sarah@acme.co | $184.30 | |

Most AI startups look at their total bill and divide by users. That tells you nothing.
Your top 1% of users might cost 50x more than average. You wouldn't know until you're bleeding money.
You're using Opus for tasks that Haiku handles perfectly. Every mismatched call is money wasted.
One stuck agent loop can burn through hundreds of dollars in hours. Without alerts, you find out on your invoice.
847 classification calls use claude-opus. Testing shows claude-haiku produces identical results for this task.
System prompt in /api/analyze includes 2,400 tokens of unused tool definitions. Removing them won't affect output quality.
38% of prompts in /api/summarize share identical prefixes. Enable prompt caching to reduce redundant input tokens.
Model Optimization
Tozil analyzes your usage patterns and finds calls where a cheaper model produces the same quality. Real suggestions, real savings.
Average customer saves 30-45% on their AI bill.
