Authors are divided on AI. A November 2025 BookBub survey of 1,229 authors found 45% use generative AI in some way and 48% refuse to. Readers are wary too: 56% in a 2025 YouGov poll said they want to know if AI was used at any stage of a book. Here is how to use AI video for marketing without hurting trust.
Keep the book human, and say so
The AI tools readers accept, such as computer-narrated audiobooks and translation, have something in common: the author's words stay the source, and the tool is labelled. A trailer that films your words is in that category. Say it plainly in the caption: the book is yours, the trailer was made with AI.
The platform rules
- TikTok requires creators to label realistic AI-generated video and audio, and can label it automatically.
- Instagram and Facebook require the “AI info” label for photorealistic AI video and realistic-sounding audio.
- Amazon KDP asks you to disclose AI-generated text, images and translations in your book. Its guidelines don't cover marketing videos, but a clear label costs nothing.
- In the EU, labelling rules for realistic AI content apply from August 2026.
Faces and voices
Never use a real actor's face or a cloned voice without written consent. Original characters avoid the problem entirely, and they belong to your book.
Rights
Ask whoever makes your trailer for a written licence to use it in ads, without a time limit, and confirm that the models used allow commercial use. Ours is in the terms.
