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%.

Provable
🏋️

Oversized models

Top-tier models on work a cheaper tier handles fine.

Flag
🌙

Missed batch

Non-urgent jobs on the full-price synchronous tier.

Flag
📏

Output bloat

Unbounded max_tokens on the most expensive token class.

Flag
👯

Duplicate calls

Repeated and retried queries paying twice for the same tokens.

Estimate
🗿

Stale models

Deprecated snapshots priced above their current-gen successor.

Provable

No 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.
