Does Midjourney train on your prompts and images?
Its terms grant Midjourney a perpetual, worldwide, irrevocable, royalty-free license to reproduce, adapt, display, and distribute the content you put in and the assets you make. That is a broad grant. Read it before you put a client’s unreleased product into a prompt.
What this means for marketers
The license you grant is in the terms. Worth considering: keep unreleased products and anything under NDA out of the tool entirely.
