Prompt Optimizer
Rewrite a system prompt shorter at equal or better quality, with a real token delta, a real dollar saving, and an honest list of what might change.
Get started-
Every dollar figure is computed from real, exactly-counted tokens on both the original and rewritten prompt — never a model-guessed estimate.
-
Pairs every optimization with an honest "risks of this change" list and a one-click handoff to the Eval Runner — a token reduction is never presented as free.
-
Marks the cache boundary in the rewritten prompt directly, so a shorter prompt is also a more cacheable one.
Frequently asked questions
This tool is powered by Claude (Anthropic).
You don't — not from this tool alone. It lists the specific behaviors that might shift and computes the real cost difference, but the only way to know for certain is to run both versions against a real eval set. That's why every result here is paired with a one-click handoff to the Eval Runner rather than a bare "done" message.
Yes — both the original and rewritten prompt are counted with this platform's real token counter, and the dollar figures are bcmath against the same admin-editable price list every other cost tool on this platform uses. The model never reports its own token count or price.
No. Paste your prompt, get the rewrite, and download or copy it. An email address is required to generate the file and enforce a fair-use daily limit; no account is created. Create a free account if you want to save versions and see a diff against earlier ones.
