AI 3D shorts generator

Length

45 to 60 seconds, in 15-second steps; about 45 seconds unless you pick another. A short lands within a fifth of the length you pick.

In each short

A narrator voice, a 3D cutaway and a builder who fixes each failure with the real part, or the real method step by step. Captions, music and sound effects.

Export

One vertical 1080 x 1920 MP4 at 30 frames a second, with post copy for YouTube Shorts, TikTok, Instagram Reels and Facebook Reels. No watermark.

Credits

45 seconds: 450 to 550 credits to make, export included. 60 seconds: 550 to 650 credits to make, export included.Quoted on ViewGum's default writer on November 13, 2026.

Changes after it's made

Once it's made, ask the chat for a change to the 3D scene, such as a wider camera, a closer framing or slower moves, or redo the animation, or have a line said another way, fact checked and voiced again with the scene re-timed to it. Each change shows its price in credits before you apply it, and if one fails, the credits for work it did not do come back.

From an AI assistant

Yes, through ViewGum's connector, which quotes the price first.

1. 1Type a topic, or pick one of the ideas ViewGum suggests, such as how a roller coaster is built.
2. 2Pick 3D Build. ViewGum writes the script, builds a 3D scene for your topic, narrates it and adds captions, music and sound effects.
3. 3Watch it, ask the chat for a wider camera or another change to the scene if you want one, then export the MP4 and post it to TikTok, YouTube Shorts or Reels.

  How the Burj Khalifa was built

  A 3D city, then the tower: piles and a foundation slab go in, the core climbs and the spire goes on at 828 metres, each step named by the narrator. A muted excerpt.

  Make one like this

• Landmarks and how they were built: towers, bridges, dams, canals and stadiums.
• Things made of parts: a house, a tunnel, a roller coaster, a cruise ship or a launch pad.
• Engineering, history and how-it's-made channels that want 3D shorts on TikTok and YouTube Shorts without learning 3D software.

• A 3D short runs 45 to 60 seconds; shorter lengths aren't offered in 3D.
• It builds things made of parts. A story about people, or a topic with nothing to build, fits a narrated faceless short better.
• The 3D is stylized, not photoreal footage, and it can't import your own 3D model or export 3D files.
• It does not post for you. You get the MP4 and post copy for each app, then post it yourself.
• It does not cut clips from long recordings.
• It does not export horizontal or square video.
• It does not have a public REST API. AI assistants connect through its MCP server.

A 3D Build short is stylized 3D animation with an AI narrator voice, and it carries no ViewGum watermark. Whether it needs a label is your call under each platform's rules.
