Token counts are estimates based on BPE approximation. Actual counts may vary slightly by model version.
About Token Counting
A fast client-side token estimator for the most popular LLM APIs. No data is sent to any server.
Why count tokens?
LLM APIs charge per token and enforce context window limits. Knowing your token count before sending a request helps you optimize prompts, avoid truncation, and control costs.
Key Features
- Multi-model Support: Estimates tokens for GPT-4, GPT-3.5, Claude, and Llama simultaneously.
- Real-time Counting: Token counts update instantly as you type.
- Context Bar: Visual progress bar shows how much of each model context window is used.
- File Import: Load .txt, .md, .json, or code files directly for batch counting.
How to Use
- Paste your prompt or text into the input area.
- View the estimated token count for each model in real time.
- Use the context bar to ensure your text fits within the model context limit.
