Start from your deep dive
Turn a big topic, a chapter outline or a script into a deep dive
Make a long-form explainer video that holds together from the first scene to the last. Atlabs builds your deep dive chapter by chapter, with the same characters, sets and props in every chapter, so viewers never lose the thread of a long story.
Rough Idea
A big topic in a line
Name the topic, the chapters you want covered and the tone. The AI writes a chaptered script, splits it into scenes with your recurring characters and builds the full video.
A deep dive into how the global shipping container changed trade, in five chapters, curious tone, one narrator.
Most Popular
Your chapter outline or research
Paste your outline with chapter headings and the key points under each. Atlabs keeps your structure and gives every point its own scene inside the right chapter.
Ch1: Docks before 1956. Ch2: Malcom McLean's idea. Ch3: The standard box. Ch4: Megaships. Ch5: What's next.
Full Script
A full chaptered script
Upload a long script with chapter titles, scene headings and voiceover lines. Atlabs animates every chapter exactly as written and keeps every scene in order.
CHAPTER 1. SCENE 1. Dockworkers carry sacks up a gangplank. VO: "Loading one ship took a week."
How It Works
From big topic to a finished long-form explainer in four steps
Paste your idea, outline, or script
Paste a big topic, a chapter outline or a full chaptered script, and Atlabs breaks it into chapters and scenes.
STEP 1
Choose a visual style & aspect ratio
Choose a style you can watch for a long time, like clean 2D, cinematic 3D or paper-cut, in 16:9 for YouTube and courses or 9:16 for short chapter clips.
STEP 2
Lock characters, scenes, & props
Lock your narrator character, the main places and the objects that return, so chapter five looks like chapter one.
STEP 3
Generate, refine, and publish
Generate the video, refine any chapter on its own, then publish the full deep dive and cut clips from each chapter.
STEP 4
50,000+ creators & teams · No credit card required
No drift across chapters
Keep the same characters, sets and props from the first chapter of your explainer to the last
In a long video, small changes add up. A face shifts, a room changes colour and viewers lose the thread. Atlabs locks your characters, your sets and your props, so a long-form explainer looks like one piece of work from start to finish.
Character consistency
Create a character once and Atlabs keeps the same face, outfit, colours and style in every scene and every video after it. Your narrator looks the same in the last chapter as in the first.

Scene consistency
Lock a setting and it keeps the same layout, lighting and mood each time it returns, so a place viewers met early on is instantly familiar when the story comes back to it.
Object and prop consistency
Key objects, maps and diagrams look the same in every scene, so the thing you introduced in chapter one is the same thing viewers see at the end.
