Première Copilot installs in two places only:
  1. The extension folder (the CEP extension + the local API engine), installed system-wide.
  2. A data folder in your Documents (cache, transcriptions, generated files, presets).
Deleting both removes the software completely. Follow the steps for your operating system.
Close Adobe Premiere Pro (and DaVinci Resolve) before you start. Files that are in use cannot be deleted, and Premiere Pro must not be running when the extension folder is removed.

​
Windows

​
1. Delete the extension folder

All extension files live under the Adobe CEP extensions folder in Common Files. Paste this path in the File Explorer address bar:
Delete the folder(s) below that exist on your machine — depending on which installer you used, only one of them will be present:
Deleting these folders requires administrator rights. Windows will ask you to confirm — click Continue.
The aescripts version also registers a classic uninstaller. You can remove it from Settings > Apps > Installed apps > PremiereGPTaescripts instead of deleting the folder by hand.

​
2. Delete the data folder

This folder holds the cache, thumbnails, transcriptions, generated audio and presets. Paste this in the File Explorer address bar (replace nothing — %USERPROFILE% resolves automatically):
Delete the whole Premiere Copilot folder. It contains the following subfolders created at install time: audio_sync · image_generation · matplotlib_cache · music_analysis · rush_db · script · seq_preset · sfx · temp · thumbnails · transcription_analysis
If you saved anything of your own in these folders (custom sequence presets in seq_preset, generated files in image_generation or sfx), back it up before deleting.

​
3. (Optional) Remove the debug registry key

The installer enables Adobe’s unsigned-extension mode. It is shared by all CEP extensions, so only remove it if you use no other third-party Premiere Pro extension. Open Registry Editor (regedit) and delete the PlayerDebugMode value in:
Removing PlayerDebugMode will break any other unsigned extension you have installed. If in doubt, leave it as it is — it has no effect once Première Copilot is gone.

​
macOS

​
1. Delete the extension folder

Open Finder, press Cmd + Shift + G, and paste:
Delete the folder(s) below that exist on your machine: macOS will ask for your administrator password — this folder is outside your user account. If you prefer the Terminal, this removes every possible variant in one go:

​
2. Delete the data folder

Press Cmd + Shift + G in Finder and paste:
Move the whole Premiere Copilot folder to the Trash. It contains the subfolders created at install time: audio_sync · image_generation · matplotlib_cache · music_analysis · rush_db · script · seq_preset · sfx · temp · thumbnails · transcription_analysis Or, in the Terminal:
Back up anything of your own stored in these folders (custom presets in seq_preset, generated files in image_generation or sfx) before deleting.

​
3. (Optional) Forget the installer receipt

macOS keeps a record of the .pkg installation. It takes no meaningful space, but you can clear it:
For the GenAI and DaVinci builds, the identifiers are com.trial17.premierecopilot-genai and com.trial17.davinciclaude.

Verify the uninstall

1

Restart Premiere Pro

Reopen Adobe Premiere Pro.
2

Check the Extensions menu

Go to Window > Extensions. Première GPT Beta should no longer be listed.
3

Check the folders

Both the CEP extension folder and Documents/Adobe/Premiere Pro/Premiere Copilot should be gone.
Uninstalling does not cancel your subscription. Manage or cancel it from your account dashboard.
Reinstalling later? Just run the installer again — it recreates both folders automatically. Note that the installer already deletes any previous version before installing, so you do not need to uninstall manually before an update.
