Find the money leaking out of your LLM bill.
Most teams overpay ~40% on OpenAI and Anthropic — caching gaps, oversized models, missed batch discounts. Upload your usage export and see exactly where, in two minutes.
Your file never leaves your browser. We can't see your data even if we wanted to.
What it looks for
Six drivers behind almost every surprise bill. Each finding comes with a monthly euro figure — split into what's provable and what's an estimate.
Caching gaps
Large prompts re-sent at full price instead of cached at 10%.
ProvableOversized models
Top-tier models on work a cheaper tier handles fine.
FlagMissed batch
Non-urgent jobs on the full-price synchronous tier.
FlagOutput bloat
Unbounded max_tokens on the most expensive token class.
FlagDuplicate calls
Repeated and retried queries paying twice for the same tokens.
EstimateStale models
Deprecated snapshots priced above their current-gen successor.
ProvableNo proxy in your path
Monitoring tools sit between you and the model, adding latency and seeing every request. We don't. You upload a billing export; nothing routes through us.
Parsed in your browser
The analysis runs as client-side JavaScript. Your usage file is never transmitted — the strongest possible privacy guarantee.
Honest math
We separate provable savings from estimates instead of inflating one big number. The floor is defensible; the ceiling is clearly labeled.

Free, no signup, nothing uploaded. If there's nothing to save, we'll tell you that too.
