How to use AI Prompt Token Estimator
- Paste your system prompt into the first field.
- Add conversation history or context in the second field.
- Enter the user message to see the full token breakdown and cost.
What is AI Prompt Token Estimator?
Complex AI prompts have multiple components — system prompt, conversation history, user message, and retrieved context. This tool breaks down each component's token count so you can optimize your prompt structure.
Identify which parts of your prompt consume the most tokens and trim where possible to reduce costs and stay within context limits.
FAQ
- Why break down tokens by component?
- System prompts are sent with every request. If your system prompt uses 2K tokens and you make 10K requests, that's 20M tokens just for the system prompt.
- How can I reduce token usage?
- Shorten system prompts, summarize conversation history, and use smaller context chunks. Every token saved reduces cost proportionally.
