Frequently asked questions

In English, 1,000 tokens is typically around 700–750 words. The exact number varies with language, formatting, and how often your text uses uncommon or compound words.

No. Everything is processed locally in your browser. Your text is never uploaded, stored, logged, or shared with CorrectTally.

Counts use OpenAI's o200k_base tokenizer (via gpt-tokenizer) — the exact encoding behind GPT-4o and GPT-4.1 — running entirely in your browser. Claude and Gemini use their own tokenizers, so their totals may differ slightly.
