You wrote the book. Now BookTok wants character cards. Instagram wants aesthetic quotes. Your newsletter needs teasers. And suddenly you're spending more time in Canva than you ever spent writing.
Not anymore. The Author Launch Kit auto-generates your entire marketing arsenal the moment your book is done.
4–6 per book
Visual cards for each main character featuring an AI-generated portrait, personality traits, trope tags like "Enemies to Lovers" or "Morally Grey," and an actual quote your character says in the book.
Each card features a full AI-generated portrait styled to match your genre, key personality traits, and trope tags that BookTok readers instantly recognize — "Enemies to Lovers," "Morally Grey," "Found Family."
Cards are sized at 1080×1350px, optimized for vertical social media formats. The styling automatically matches your book's genre — dark and moody for dark romance, bright and warm for contemporary fiction.
Where to use them: BookTok (TikTok) character introduction videos, Instagram carousels and Reels, Pinterest boards. The trope-tag format is native to how the BookTok community talks about characters — it's the visual language of that space.
8–10 per book
The system scans your entire book and pulls out the most emotionally intense lines — metaphors, dramatic moments, gut-punch dialogue — then places them on AI-generated backgrounds that match the mood.
Dark forest backgrounds for dark romance. Golden hour for contemporary love stories. Neon cityscapes for sci-fi. The AI matches the visual atmosphere to your book's mood automatically.
Two sizes included: 1080×1080px for your Instagram feed, and 1080×1920px for Stories and TikTok.
Where to use them: Aesthetic quotes are among the most shared content on Bookstagram and Pinterest. Quote carousels and aesthetic reels are a core part of visually rich book marketing. On TikTok alone, BookTok quotes have accumulated over 9.5 million posts.
5 per book
Short 100–200 word excerpts from your book's highest-tension scenes — the first meeting, the betrayal, the confrontation. Each one drops you right into the action and cuts off before the resolution.
Every teaser comes with a hook line like "The moment everything changed between them…" ready for your next BookTok video, Instagram caption, or email newsletter.
The AI identifies the most emotionally charged scenes in your book and extracts the passages that will make readers need to know what happens next.
Where to use them: BookTok video overlays (text-on-screen with atmospheric audio), Instagram captions, email newsletter hooks, and Goodreads updates. Book teasers with dramatic visuals are one of the top-performing BookTok content formats.
All auto-generated from your book's text and Story Thread Engine data. No copy-pasting. No Canva templates. No designer.
Your book is ready. Now your marketing is too.
