Z Video Generator

Turn a prompt into a video.

A native macOS client for the Z.AI video API. Write a prompt, generate up to eight clips in parallel, and keep a tidy library of the ones you keep — in a Liquid Glass workspace built for macOS 26.

01 Built for the Mac

Native Swift

Pure Swift and SwiftUI from the interface down — no Electron, no third-party runtimes. Just the app and Apple’s frameworks, built for macOS 26 (Tahoe).

Liquid Glass

The interface uses macOS 26’s Liquid Glass material — adaptive surfaces that frost under Reduce Transparency and gain a border under Increase Contrast, automatically.

Z.AI, directly

Talks to the Z.AI video API over HTTPS with no middleman server. Bring your own Z.AI key — there’s no separate account and no data collected.

Keychain-secured

Your API key lives in the macOS Keychain and is sent only to z.ai. It’s never in the app bundle, a log, or anywhere this site can see.

02 What it is

Z Video Generator is a focused workspace for Z.AI video generation. Each job is an independent request with its own prompt and settings, so you can line up several and let them run in parallel.

It’s a bring-your-own-key app: paste a Z.AI API key and it’s stored in the macOS Keychain, used only to call z.ai over HTTPS. There’s no server in between and no account to create beyond your Z.AI key.

03 How it works

  1. 01

    Add your key

    Paste a Z.AI API key once. It’s stored in the macOS Keychain, and the connection light confirms it works.

  2. 02

    Write a prompt

    Describe the clip and pick the model, size, frame rate, and audio. Save prompts you like to the library.

  3. 03

    Generate

    Submit and watch the status live. Queue several jobs and they run in parallel up to the concurrent limit.

  4. 04

    Play & save

    Preview the result, open it on z.ai, or save the MP4 to Downloads. Regenerate or tweak and try again.

04 What’s in it

Prompt library

Save prompts that worked and reuse them to start a new generation with all their settings.

Up to 8 in parallel

Run several generations at once, throttled to Z.AI’s limits. Each job has its own prompt and settings.

Up to 4K, with audio

Resolutions up to 4K, landscape to portrait, 30 or 60 fps, optional audio — per job.

Survives restarts

In-progress renders resume after you quit and relaunch instead of being orphaned.

Native playback

Preview a render in-app, open it on z.ai, or save the MP4 straight to Downloads.

Sandboxed

App Sandbox on; the only network destination is z.ai. No analytics, no tracking.
