Shrink a Prompt Without Changing What It Asks

Strip the padding out of a prompt — dead whitespace, boilerplate politeness, redundant framing — and see the tokens and money saved.

This optimiser removes the padding from a prompt — repeated whitespace, greetings and sign-offs, politeness scaffolding, self-referential framing, hedging and verbose connectives — at three levels of aggressiveness, then measures the exact token reduction and converts it into money per call, per ten thousand calls and per million at your chosen model's rates.

Frequently asked questions

Will shortening my prompt make the output worse?

Removing greetings and politeness has no measurable effect on quality. Removing hedging and qualifiers sometimes does, which is why that lives at the aggressive setting and every change is listed rather than applied silently. Always read the result.

What saves more than rewording?

Prompt caching, by a wide margin — a stable prefix reused across calls bills at roughly a tenth of the input rate. After that: cutting few-shot examples, which are usually the biggest single block, and retrieving less context. Wording changes are the smallest of the three levers.
