AI Token Counter
Estimate token counts locally with a documented characters÷4 approximation.
Tool workspace
Estimates tokens locally as characters ÷ 4 (ceil). Real model tokenizers vary. No AI API call — text stays in your browser.
How it works
Paste text to estimate tokens as characters ÷ 4 (ceil). Also shows character and word counts.
This is a local approximation — real tokenizers vary by model/vendor. No AI API call. Empty input clears the result—no error.
