AI Director
Reads your voice, gaze, cursor and typing to cut between talking-head, hybrid, working and cursor-focus shots — with cinematic inertia and beat-synced cuts.
Premium native Windows app · for pro streamers

Record vertical & horizontal at the same time.
live.hexart.io is a GPU-native live compositor that turns multiple desktop monitors into a cinematic, AI-directed broadcast — and captures a 16:9 and a 9:16 master in a single take. In the edit you just swap the source to ship the vertical cut. No re-recording, no reframing.

- AI Director
One take. Two formats.
Most creators shoot horizontal, then re-cut a separate vertical for Shorts, Reels and TikTok. CAST renders both canvases live — a 1920×1080 stage and a 1080×1920 stage — from the same session, perfectly in sync.
16:9
+
9:16
In your editor, the vertical cut is just a source swap away. That is hours saved on every upload.
Built to look directed, not captured.
Dual-canvas, dual-GPU
The 16:9 stage renders on one NVIDIA GPU, the 9:16 stage on the other. Zero-copy NVENC keeps both encodes off your render thread.
Holographic compositor
Frosted glass panels, 3D depth & parallax, auto-exposure, a procedural cursor with physics, and a radial music spectrum that reacts to your audio.
Multi-monitor capture
Made for presenting across several Windows desktop monitors — the shot follows the window you are actually working in, then eases to the desktop when you step away.
Broadcast audio chain
Noise reduction, gate, compressor, priority ducking (voice > system > music), LUFS auto-mastering and a virtual-mic send to any app.
Stream & record everywhere
YouTube, Twitch, TikTok Live and Facebook Live — per-platform format and quality. Crash-safe recording with ISO multitrack and a shared timecode.
Hardware requirements
CAST is a high-end, GPU-native tool. It is built around NVIDIA encoders and dual-GPU rendering — please check the requirements before you buy.

For creators who present, not just talk.
If your content lives on the desktop — software, design, dev, trading, tutorials, reviews — CAST makes a multi-monitor workflow look like a broadcast, and hands you the vertical cut for free.
“One session, two masters. The vertical is a source swap in the edit.”
FAQ
Is the license tied to my computer?
Yes. Your serial activates on your device with a hardware fingerprint and is validated against our server. You can move it between machines with help from support.
Do I need two GPUs?
Two NVIDIA GPUs are recommended for the full dual-canvas experience. A single NVENC-capable NVIDIA GPU runs the app; performance and simultaneous dual-format encoding scale with your hardware.
Does it work on macOS?
Not yet — Windows is available today, macOS is coming soon. Join the list on purchase to be notified.
Can I really record vertical and horizontal together?
Yes. Both canvases render and encode live in one session, in sync, so editing the vertical cut is just swapping the source.
