AI Token Counter
Estimate tokens in prompts, documents, and code without uploading your text. Then translate the estimate into rough API input cost.
Estimated input cost by model
Use this as a quick planning estimate. Actual billed tokens depend on the provider tokenizer, caching, tools, and request structure.
| Model | Published input rate | Estimated input cost |
|---|
Why the number is labeled “estimated.”
Different model families tokenize the same text differently. This version intentionally uses a lightweight heuristic so it can stay static, fast, and private.
Use it for budgeting and context planning, not as a substitute for provider-side usage accounting.
AI token counter questions
Is this token count exact?
No. It is a cross-model estimate because tokenizer behavior differs by model family.
Does the text leave my browser?
No. This page has no prompt submission endpoint; the calculation happens locally.
Can I use this for API budgeting?
Yes for rough planning. For billing reconciliation, use the token usage returned by your API provider.
