Every AI model reads text as tokens, not characters or words — and how many tokens your text becomes is what actually determines your API cost and whether it fits inside a model’s context window. This tool gives you a fast, practical estimate.

Estimated Tokens

Estimate uses the widely-cited approximation of ~4 characters per token for English text (roughly ¾ of a word per token). Actual token counts vary by model family and can differ by 10-20% from this estimate — use your provider’s official tokenizer for billing-critical work.

Why token counts matter

API pricing for every major AI provider is charged per token, not per word or character, and every model has a maximum context window measured in tokens. Knowing your token count before you send a request helps you avoid surprise costs and truncated context.

Getting an exact cost

Character-based estimation is fast but approximate. Once you know roughly how many tokens your text uses, head to the AI Model Cost Calculator to see exact current pricing across every major model and find the cheapest option for your workload.

Frequently Asked Questions

Is this exact or an estimate?

This is an estimate based on the standard ~4 characters per token approximation for English text. Actual tokenization varies slightly by model family.

Does it work for code?

Yes, though code often tokenizes at a different rate than prose since it has more symbols and shorter tokens.

Is my text stored anywhere?

No. The counter runs entirely in your browser and nothing is sent to our servers.
