AI Token Counter
Paste text to estimate token usage and optionally multiply the estimate by a cost per million tokens.
Heuristic estimate only; tokenizer results vary by model.
Estimated cost:
A QUICK WALKTHROUGH
How to use this tool
- Paste the text to estimate.
- Choose a model family and optionally enter a price per million tokens.
- Run the estimate and treat the result as an approximation, not an exact tokenizer count.
Heuristic estimate
This tool does not load a model tokenizer. Token boundaries vary by provider and model, so the count can differ from the exact usage reported by an API or invoice.
Optional cost calculation
When you enter a rate per million tokens, the tool multiplies that rate by its estimated token count. The result is illustrative and is not a provider quote or invoice.

GOOD TO KNOW
Common questions
Is the token count exact?
No. It is an estimate from a transparent local heuristic, not an exact model tokenizer.
Does choosing a model family load its tokenizer?
No. The model family is a reference for your estimate; no model tokenizer is downloaded.
Is the estimated cost a quote?
No. It is a simple calculation from your optional rate and the approximate token count.
