Method
Local estimate
Token totals are estimates. Each model family uses its own tokenizer and may count structured messages differently.
How it works AI Token Counter
The counter measures characters, words, sentence structure, and punctuation locally, then applies a transparent token estimate. It is useful for planning; provider tokenizers may differ.
Example
Paste a system prompt, product brief, or support reply to estimate its tokens before you send it.
Frequently asked questions
- Which models are supported?
- The estimator provides planning support for GPT, Claude, Gemini, Llama, Mistral, and DeepSeek model families.
- Is this an exact tokenizer?
- No. This browser-only MVP provides a clearly labelled estimate rather than uploading text to a third-party tokenizer.
