PromptPerfect

Overview

PromptPerfect, from Jina AI, takes a prompt you've written and rewrites it to work better against a chosen model, covering both text models and image models. The idea is to hand off the fiddly work of phrasing — you type a rough request, pick your target, and it returns a reworked prompt tuned for that system, sometimes with a few candidate versions to compare. For people who don't want to learn prompt-craft, it lowers the barrier to a usable result. It's fair to be sceptical about how much it adds. The optimisation is a black box — you can't see why it chose a rewrite — and as models get better at parsing plain requests, an automated middle layer buys less than it once did. In practice a careful manual edit often matches or beats it, and the service runs on paid credits. Worth a try when you're stuck on a prompt and want alternatives to react to, but not something to build a workflow around.
