Token counter
Count tokens in any prompt or document right in your browser. Nothing is uploaded. Useful for checking prompt size before you hit a model context limit.
Token count uses the exact GPT (o200k) tokenizer. Counted in your browser, never uploaded.
| Model | Tokens | Per request | Monthly | Context |
|---|---|---|---|---|
| Qwen3.8 Max | 0 est. | $0.0030 | $3.00 | 0.1% |
| DeepSeek V4 Flashcheapest | 0 est. | $0.00014 | $0.14 | 0.1% |
| Claude Opus 5 | 0 est. | $0.013 | $12.50 | 0.1% |
Token counts vary by tokenizer and model; non-OpenAI counts are estimates. Cost is an estimate and provider pricing can change. See each model's source on the pricing page.
Why count tokens?
Token count decides three things: whether your prompt fits the model context window, how much the request costs, and how fast it responds. Counting before you send avoids truncated context, surprise bills and failed requests, which is why a token counter is a routine step for prompt engineers and anyone shipping on an API.
FAQ
Is my text sent to a server?
No. All counting happens in your browser. Pasted text never leaves your device.
Can it count tokens for long documents?
Yes. Paste text of any length; the counter handles large documents and reports the total, with a token visualization for the first few thousand tokens.
