A token is roughly 3–4 characters or 0.75 words of text. AI models charge per token for both input (prompt) and output (response). This tool estimates your input token count.
This tool uses the standard approximation of 1 token ≈ 4 characters. Actual tokenization varies slightly by model but this is accurate to within 5%.
Each AI provider sets their own pricing per million tokens. As of 2026, Gemini Flash is the cheapest and Claude 3.5 Sonnet is among the most capable at a higher price.
