About this tool
The AI Token Counter estimates how many tokens your text will use when processed by Claude and similar large language models. It is built for developers, writers, and anyone managing API costs who needs to understand token consumption before sending requests. Tokens are not the same as words or characters, so having an accurate count matters when you are working within context limits or budgeting API usage.
Reach for this tool when you are drafting prompts and want to avoid hitting context window limits, when you are estimating costs for a project using the Claude API, or when you are debugging why a request was truncated or rejected. It is especially handy before pasting large documents into a chat or automated workflow.
How to use it
- Paste or type your text into the input field on the tool page.
- The token count updates automatically as you type or after pasting.
- Review the token total displayed below the input area.
- Compare the count against your target model’s context limit or pricing tier.
- Trim or split your text if the count exceeds your budget or context window.
- Copy or note the final count before building your API request or prompt.
Pro tips
- System prompts and conversation history both consume tokens, so count everything you plan to send, not just the user message.
- Whitespace, punctuation, and uncommon words often tokenize less efficiently than plain prose, inflating counts unexpectedly.
