Prompt Token Optimizer FAQ
Does the optimizer rewrite my prompt creatively?
No. It applies conservative, transparent reductions such as filler removal, whitespace compression, and Markdown cleanup so the prompt intent remains intact.
Can I control what gets optimized?
Yes. Toggle filler removal, whitespace compression, Markdown simplification, and known abbreviations independently.
How are token savings calculated?
The tool counts the original and optimized prompt with the selected model profile, then reports saved tokens, savings percentage, and estimated input cost reduction.
Is it safe for long prompts?
Large prompts are processed in a Web Worker above 500KB, keeping the UI responsive while all text remains local.
