30Days
See what happens when YOU enter any fictional world for 30 days. Name a universe, describe the premise, and Zyvo builds eight connected scenes across Day 1, 10, 20, and 30 — narrated from your actual finished footage.

How it works
From one universe to a full story
02
Describe your 30 days
Write your own premise, or let AI write a viral-shaped one for you. You're always the protagonist — even when the premise is a world-level crisis.
03
Zyvo builds a consistent world
A world bible locks the visual style and canon characters, then generates 8 scene images across four milestone days and animates each into a 5-second clip — with you compositionally central in every one.
04
AI narrates your actual footage
Once the 8 clips are done, Zyvo watches them and writes one continuous hook and narration story from what actually happens on screen. Edit it, pick a voice, and export the stitched video.
A real 30 Days generation — LEGO Ninjago universe, straight out of Zyvo.

30 Days FAQs
What is 30 Days?
30 Days is a video format where you name any fictional universe and a premise for spending 30 days inside it. Zyvo generates four milestone days with two connected scenes each, keeps you as the protagonist, narrates the finished footage, and stitches a final vertical video.
Can I use any fictional world, or only the examples shown?
The examples are just starting points. You can type in any world you want to visit.
Do I have to write the premise myself?
No. Turn on AI idea mode and Zyvo writes a viral-shaped premise for your chosen universe, which you can use as-is or edit before generating.
How long is the final video?
Eight scenes at roughly 5 seconds each, stitched with narration into one continuous vertical video — about 40 seconds total.
Do the clips come with sound?
The 8 generated clips are silent. Narration is added afterward: Zyvo writes a continuous story from your actual finished footage, you pick one of 12 voices, and the final export combines the clips with that narration.
Which plans include 30 Days?
30 Days is included on Starter, Pro, and Generative plans, with three image-quality tiers — 1K on Starter, 2K on Pro, and 4K on Generative. It isn't available on the free plan.
