Meta Prompt Lab vs Promptify.

Both build prompts. One does it privately on your iPhone with a 20-agent pipeline; the other in the cloud.

A private, on-device alternative to Promptify.
The short version

Promptify is a prompt-generation tool that helps you craft prompts for AI models, typically through the cloud. Meta Prompt Lab does the same job with a different philosophy: it turns one sentence into a professional prompt entirely on-device, refined by a 20-agent pipeline in around 100 seconds. The key differences are privacy, the one-sentence input, iOS-native design and a one-time lifetime pricing option. As a direct alternative, it suits people who want prompt-building that stays on their phone.
