100% in-browser via the GPT (BPE) tokenizer — exact for OpenAI models; Claude and Gemini use their own tokenizers (counts are close). Nothing is uploaded.
The Tokenizer Visualizer shows how text is broken into the tokens a language model actually reads. It highlights each GPT (BPE) token in color, shows token IDs, and reports total tokens and characters-per-token. It runs entirely in your browser using the real GPT tokenizer.
Enter text
Type or paste any text.
Inspect tokens
See each token highlighted; switch to 'Token IDs' for the numeric encoding.
Read stats
Check total tokens and chars-per-token to understand cost and density.
