FAQ

How accurate is this Gemini 3 Flash token count?

Exact when a server API key is configured — counts come from Google's own count-tokens endpoint. Otherwise a clearly-labeled local estimate is shown.

Does my prompt leave the browser?

Only to Google's count-tokens API (which doesn't run the model or store your prompt) — nothing is logged by this site.

What does a Gemini 3 Flash request cost?

Input tokens × $0.5/1M plus output tokens × $3/1M (standard tier, as of 2026-07-14). The calculator above does this for your actual prompt.
