Frequently Asked Questions (FAQ)
Q: Are my confidential prompts or code snippets uploaded to any server?
No. All token calculations and visualizations run 100% locally in your browser memory. Zero network requests are made, protecting your business prompts and confidential keys.
Q: How accurate is the token count across different models?
The tool uses standard BPE segmentation rules and model-specific cost matrices. While individual proprietary vendor tokenizers have minor token boundary variations, this provides reliable cost and context window estimates for development budgeting.
