A Vow of Thorns — Romantasy template
How it works
Pick a template
Three to start: LitRPG / progression fantasy, cozy mystery, dark romantasy. Each one has its own visual style, music, and narrator voice.
Upload your cover, type your hook
Title, author, your one-line tagline, a brief setting description. The AI generates atmospheric backgrounds that match the book — not generic stock.

Vertical for TikTok and Reels. Landscape for YouTube and X. Square for Instagram. All three rendered from one purchase, emailed to you.

One purchase. Three aspect ratios.
Same trailer, three crops. So you can post the same launch on TikTok, YouTube, and Instagram without re-cutting in CapCut.
YouTube / X / web
1920×1080
TikTok / Reels / Shorts

Instagram feed

All three rendered from one $29 purchase. No re-uploads.
Built for the author who doesn't have time for Premiere
Reedsy trailers cost $200+ and take a week. DIY in Premiere or CapCut takes hours per book and you're still picking stock footage that doesn't match your story. This tool makes a trailer that looks like your book — same color palette as the cover, atmosphere matching the setting, real lines from your blurb — in under a minute.
Built by an indie author who got tired of either option.
Hero tier — $79
Real motion, not just zoom
Standard zooms slowly across an AI-generated still. Hero generates 4-second motion video clips per scene with Veo, then loops them through the trailer.

Common questions
Will the trailer match my book or feel generic?
We use your cover, your blurb, and a setting hint you write to generate per-book atmospheric backgrounds — not stock footage. The cozy mystery sample looks nothing like the LitRPG sample because they're built from different prompts. That said: AI-generated, so the result is good-not-Pixar.
Is this AI?
Yes — image generation (FLUX), narrator voice (ElevenLabs), music (ElevenLabs Music), composition via ffmpeg. We say so on the result page so you can disclose it if your audience cares.
How long until I get the trailer?
Render takes 30-60 seconds for a fresh book. You get an email when it's ready with a permanent link to download.
What aspect ratios do I get?
All three: 9:16 vertical (TikTok, Reels, Shorts), 16:9 landscape (YouTube, X, web embeds), 1:1 square (Instagram feed). Same content, three crops.
Can I edit the trailer afterwards?
Not in-app, but the MP4 is yours — drop it in CapCut, iMovie, Premiere, whatever. If you want different text or a different scene order, just tell us and re-render.
