Installation

extynt installs as a panel inside After Effects.

Requirements

  • After Effects 2025 or 2026 on Windows, or After Effects 2026 on macOS. Older versions are refused. Versions newer than 2026 run, marked experimental.
  • An API key from a model provider, or a local model. See Models and effort.

macOS

  1. Quit After Effects.
  2. Open the extynt-…pkg installer from your beta invite. It is signed by extynt and notarized by Apple, and asks for an administrator password once, because the plugin goes into the After Effects folder.
  3. Open After Effects.
  4. Choose Window › extynt. Dock the panel wherever you like.

extynt supports Apple silicon Macs with After Effects 2026. Nothing else needs installing. Your chats and settings stay in your own user folder.

Windows

  1. Quit After Effects.
  2. Run extynt-…-setup.exe from your beta invite. Windows asks once for administrator approval, because the plugin goes into the After Effects program folder.
  3. Open After Effects.
  4. Choose Window › extynt. Dock the panel wherever you like.

extynt supports 64-bit Windows 10 (version 1809 or later) and Windows 11. It uses the Microsoft WebView2 runtime, which current Windows already includes. If the panel stays blank, install WebView2 from Microsoft. Your chats and settings stay in your own user folder.

Updating

Quit After Effects and run the new installer over the old one. It replaces the old install. Your chats and settings stay.
