AI Subtitle Studio

Installing AI Subtitle Studio and first launch

AI Subtitle Studio is a desktop app for Windows and macOS. This page covers downloading, installing, and what you will see the first time you open it.

Download the app

Download the installer for your platform from the Download page:

  • Windows — Windows 10 or 11, 64-bit.
  • macOS — Apple Silicon (M1–M4), macOS 12 Monterey or newer.

The app is free to download and try. Several screens work without a license, and the rest unlock with a one-time license — see Activating your license.

Install

Windows: extract the downloaded .zip and run the installer inside it.

macOS: open the .dmg and drag AI Subtitle Studio into your Applications folder. On first launch, macOS Gatekeeper may ask you to confirm you want to open an app downloaded from the internet — this is expected for apps distributed outside the Mac App Store.

The installer also adds Open with for subtitle and video files and, on Windows, right-click actions on videos for Transcribe and Extract subtitles. It never makes the app the default for any file type.

What you see on first launch

The app opens to the Dashboard, a summary of what you have done with the app — empty at first. Two things usually need attention before you can transcribe or extract anything:

  • Dependencies — the app relies on a few external tools (FFmpeg and a speech engine such as Whisper) that it downloads and manages for you. The sidebar shows FFmpeg required until the core tool is installed. See Installing dependencies.
  • License activation — screens such as Transcribe, Extract and Edit Subtitles show an Activation required screen until a license is active. See Activating your license.

Settings is always reachable, even before activation, so you can enter your license key.

The main screens

The left menu groups the screens in the order the work happens:

FAQ

Do I need an internet connection to use the app?
Only for downloading the app and its tools, activating your license, checking for updates, AI translation and the YouTube Transcript screen. Transcription, extraction, conversion, syncing and cleanup run offline once the tools are installed.
Can I use the app before buying a license?
Yes. The Dashboard, YouTube Transcript, Embed, the subtitle Tools (except Sync), Settings and Translate with credits work without one. Transcribe, Extract, Edit Subtitles, AI Clean Up, Convert, Sync, Sermon Mode and Dubbing need an active license.
Does it run on Intel Macs or Linux?
No. Official builds are Windows (64-bit) and macOS on Apple Silicon.
