Frequently asked questions
Is this token count exact?
No. This browser tool uses a practical estimate based on text length and word count. Exact tokenization differs by model. Use it for planning before export, not billing.
Does the text leave my browser?
No. The calculator runs in your browser. It does not upload your pasted text to Riflet.
Why do I need to reserve output tokens?
The model needs room to answer. If source context fills the entire window, the answer may be short, truncated, or less useful.
How does this relate to Riflet?
Riflet shows token estimates while you select files. This standalone tool is useful for checking pasted text or exported context snippets.
