Estimate Your Token Count
How This Estimate Works
This tool uses a simple heuristic (roughly 4 characters per token, blended with a word-count-based estimate) rather than an exact tokenizer, since exact token counts vary by model and provider. For a rough planning estimate this is generally close enough; for exact, billing-critical counts, use your specific provider's own tokenizer library.
Why Token Count Matters
Most AI API pricing is based on token count for both your input and the model's output — see our Tokenization page for the full explanation, and our Cheapest LLM API roundup if cost is your primary concern.

Frequently Asked
Is this an exact token count?
No, it's a rough estimate using a simplified heuristic; for exact counts, use your specific AI provider's own tokenizer library.
Why does token count vary between providers for the same text?
Different providers and model families use their own specific tokenization schemes, which can produce slightly different counts for identical text.
Does this tool send my text anywhere?
No, this calculation runs entirely in your browser; your text isn't transmitted anywhere.
Where can I estimate cost, not just token count?
See our Calculators page for cost-estimation tools, or our Pricing directory for current per-token rates by provider.
