Frequently asked questions

Is the token count exact?

No. It is a provider-neutral planning estimate. For billing reconciliation, enter the exact usage value reported by the provider or its official tokenizer.

Can every pricing page be parsed?

No. Pricing pages change and some render data with JavaScript or contain tiered rules. The importer extracts conventional HTML tables and always requires review; manual entry remains available.

What is saved?

Only pricing plans you explicitly save are stored in localStorage. Prompt text, imported page bodies, and calculations are not persisted or added to the URL.
