Why "offline" matters for a plugin specifically

A lot of Premiere Pro plugins that claim AI features are really just a thin panel wrapped around a cloud API call. CaptionLab isn't — the AI model runs locally, so the plugin keeps working even with no internet connection.

🧩

Native panel, not a webview

Installs like any standard CEP/UXP Premiere Pro extension — Window → Extensions → CaptionLab.

🔌

No API key setup

Nothing to configure, no cloud account to connect — it works right after the one-time AI engine install.

🖥️

Mac and Windows

Same offline plugin, same one-time price, on both Apple Silicon/Intel Mac and Windows 10/11.

What "offline" doesn't mean

To be precise: the one-time AI engine setup (downloading Python, ffmpeg, and the Whisper model, ~3GB) does need an internet connection the first time you install. After that, transcription itself is fully offline — the plugin just needs a brief periodic license check to stay active, unrelated to your footage.

Frequently asked questions

Do I need to reinstall the plugin every time I go offline?
No — once the initial AI engine setup is complete, CaptionLab keeps working offline indefinitely, aside from an occasional brief license re-check.
Is it a real Premiere Pro panel, or does it open a browser window?
It's a native Premiere Pro extension panel, docked in your workspace like any other panel — no separate browser or app window.
Does the plugin work the same on Mac and Windows?
Yes, feature parity on both, with the Windows version optionally using an NVIDIA GPU for faster transcription.
