A prompt optimizer that rewrites structure — not vibes.
If you already have a messy prompt for an OpenAI-style chat, paste it here. We restructure goal, constraints, and output format on your machine so you can tighten the ask before you hit send.
Switch Claude or Gemini tone presets when the destination model changes — and read the “no model API” label; this is a structured rewrite, not a hidden cloud call.

How this rewrite works
We do not send your text to a model. The optimizer walks a checklist — task, constraints, output shape, filler cuts, optional light framework — and pulls tangled prompts apart so the model answers instead of guessing.
Every edit shows up as a redline you can read at a glance. Nothing is invented and nothing is hidden; if a line got cut, you'll see why. It's closer to a copy desk than a magic button.

Browse all templatesThe four things we check
Most prompts fail at one of four spots. The optimizer walks each one and only rewrites what needs fixing — the rest of your wording stays yours.
Task
The actual ask, stated once up front — not buried three lines into context.
Audience
Who the output is for, so reading level and framing land where you need them.
Tone
A short, honest voice note instead of adjectives that cancel each other out.
Format
The shape of the answer — length, sections, list vs prose — named before the model picks for you.
Built for people who send a lot of prompts
Copywriters cleaning up a client brief. Marketers spinning campaign variants. Operators writing the same request twenty times a week. If you've pasted a prompt, sighed at the reply, and rewritten by hand — this skips that loop. The pass you'd do yourself, if you had the patience.
