AirPrompt

AirPrompt is a lightweight prompt-engineering workspace aimed at people who iterate on instructions for large language models. Instead of juggling a notes app, a chat window and a spreadsheet, you keep a library of prompts in one place, tweak a version, and run it against several closed-source and open-source models without entering your own API keys.

The core idea is fast comparison. You write a prompt once, attach one or more data inputs, and AirPrompt fires it at every model you have selected so differences in tone, accuracy and formatting become obvious. Because inputs can be uploaded in bulk, the same prompt can be validated across a whole set of examples rather than a single test string.

Teams use it to settle internal debates about prompt wording, to regression-test a prompt after a model update, and to choose the most cost-effective model for a recurring task. It suits prompt engineers, product teams and marketers who need evidence that a prompt actually works, not just a gut feeling.
