Tiktokenizer

As a token usage tracker for developers, Tiktokenizer is built around billing: it counts the tokens your AI app consumes and lets you charge customers in proportion to that usage.

Tiktokenizer is a developer tool for tracking and billing LLM usage, geared toward people building on OpenAI's Chat API.

Usage is tracked in real time, so you can see what each user consumes as it happens.

A simple interface lets you browse user data, and pre-built code snippets cut down the work of wiring the service into an existing app.

Tiktokenizer also integrates with the Moderations API, which adds a content safety check to the same setup.

There is a clear catch.

The service requires integration with OpenAI's Chat API, so it does not fit if your app runs on another provider.

You also handle API keys and authentication yourself during setup.

If you resell AI features and want customers to pay for what they actually use, Tiktokenizer covers that job directly, with billing meant to be transparent and fair to both sides.
