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.

Your content. Your brand. Your tools.
Organize photos, footage, documents, and web links into reusable libraries.

Filled with intelligently‑generated visuals.
Explore Asset Libraries →Save your brand colors, fonts, logo, and intro/outro media into a kit. Select it when creating a video and your identity carries through every frame automatically — from the color of your subtitles to the intro that plays before scene one.
Create a Brand Kit →Export your entire project — clips with narration, music track, subtitles, and an FCPXML editing timeline — as a single ZIP. Open it in Adobe Premiere Pro, DaVinci Resolve, or Final Cut Pro and continue editing exactly where Slenvox left off.
Start Creating →A freelance editor charges $300–500 per video. Slenvox Professional costs less than one day of their time — for an entire month of production. See pricing →

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.
