Helion 3.1 Engine

Create Videos at Speed of Thought
— no hustle

Describe your idea. Or the whole script. Set parameters — video duration, tone, and more. Optionally, add reference material (photos, videos, documents, web links) and your brand identity (logos, colors, intro, outro, and more). The Helion Engine produces the complete video: script, cinematic visuals, narration, music, captions, and overlays. Everything is intelligently woven together, your brand identity running through it all. Tweak anything, or don't. It's ready. Take it further in your own editor — export a zip file with the XML and all assets, compatible with Adobe Premiere Pro, DaVinci Resolve, Final Cut Pro, and more.

The Origins of Coffee

Let's address some elephants.

Yes. Every new account gets 5 free minutes of video production. No credit card, no catch. Create a real video and see the quality for yourself before you decide anything.

Documentaries, explainers, tutorials, product reviews, marketing videos — anything you can describe in words. Optimized for YouTube, TikTok, Instagram, LinkedIn, and more.

None. You type, Helion produces. You can review and tweak individual scenes if you want, but it's entirely optional — the video is ready to publish as-is.

You have full editorial control. Swap any scene with stock footage or your own uploads. Change the narration voice. Adjust music. Reorder scenes. Toggle subtitles and keyword overlays. Regenerate any clip. Your video isn't final until you say it is.

Every Slenvox video goes through a full production pipeline running on H100 GPUs — the same hardware used for Hollywood visual effects. You get professional narration, AI-composed visuals, background music, subtitles, and text overlays. Your free 5 minutes produce the exact same quality as paid plans. Try it and compare against any freelance editor's output. Not satisfied? 14-day full refund.

No. YouTube's policy allows AI-generated content as long as it provides value and isn't misleading. Slenvox videos are original productions — unique scripts, narration, and visuals generated specifically for your topic. They're treated the same as any other video by YouTube's algorithm.

Yes. No contracts, no lock-in periods. Cancel with one click from your account settings. Your videos stay available for download even after cancellation.
