What it costs to run
Every model and paid call recorded with who, which venture and why, for the person who runs the product.
01What it is
The product records what every model call and every paid service call costs, priced at the rates the platform admin enters, with the account, venture, feature and reason behind it. Nobody else sees any of it.
02Why it exists
A product that writes and researches for you spends money every time it does. Without a record, a plan that costs ten times what it should, or a free flow somebody found a way to run in a loop, shows up only on an invoice weeks later.
The record is what makes limits fair: the fair-use line on each plan is read from it, so it can never be argued with, and it is what tells the person running the product what each plan really costs to serve.
03How to use it
- 01Nothing to do as a founder: recording happens on its own and never slows or stops your work.
- 02Your usage page shows what you have used, never what it cost.
