Before you download.
What Mac do I need?
An Apple Silicon Mac running macOS 14.4 or later, at least 8 GB of memory, and approximately 2 GB for the speech model, with another 5 GB when adding translation. SeedVR2 enhancement requires at least 16 GB of memory. File conversion does not require AI models.
Does Polyglot work offline?
Media and subtitle processing runs locally after the required models are downloaded. Model downloads, video-link imports, purchase, activation and update checks use the internet. See the privacy page for connection details.
Which languages can it transcribe?
Speech recognition supports 25 European languages. Translation targets are selected separately; a translation option does not imply support for recognizing speech in that language. Review AI-generated wording before sharing.
Can I work with subtitles without a video?
Yes. Open an SRT or WebVTT to edit, translate or convert it. Export SRT, VTT, readable TXT or a bilingual source-and-translation pair. You can optionally attach the matching video for review.
How does the seven-day trial work?
Your trial starts with your first transcription or translation job and includes unlimited files and languages for seven days. No account or payment details are needed. Afterward, Pro keeps transcription and translation available for €29.99 once. Editing, conversion, text export, timing adjustments and video tools stay free.
Will a compressed video fit any upload service?
A successful maximum-size export fits the byte limit you entered. Services can also restrict format, duration or resolution. Check their requirements and leave some size headroom.
How do app updates work?
Use Check for Updates… in the Polyglot menu for signed updates. If an older version has no updater, install the current release manually once.
