AI cost per customer

Know what each customer costs you in AI.

Your OpenAI and Anthropic bills give you one number. Tilwe splits it by customer and by feature, so you can see who you are losing money on.

Free audit: a one-page report on where your AI money goes, plus 30 minutes with the founder.

We store usage details, never your prompts.

We only read your usage. Your prompts stay yours.

Reads usage only

Only reads usage

OpenAI and Anthropic need an admin key for usage and cost reports. Tilwe only uses it to read those.

Encrypted at rest

Keys are encrypted with AES-GCM before they touch the database.

No prompt storage

The gateway records tokens, cost, customer and feature. Never the text.

Do you see my prompts?

No. We store usage numbers only.

Can I delete my key?

Yes, any time. Or turn on One-time audit and we delete it right after the import.

Are you SOC 2 certified?

Not yet. We will say so here when we are.
