Frequently Asked Questions

Quick answers to common questions about Glucose.

Why is it called Glucose?
'Glucose' is a play on "glued, 'coz." Glued to it because the playback experience is that good.
Which formats are supported?
Common video formats like MP4, MKV, AVI, MOV, WebM, WMV, and more. Audio formats including MP3, FLAC, WAV, AAC, OGG, and M4A. Subtitle files (SRT, VTT, ASS, SSA, SUB), plus Glucose can extract subtitle tracks embedded directly in MKV and MP4 containers. Playback of unusual or older codecs depends on what your system supports.
Does it remember where I stopped?
Yes. It saves your position in every file automatically, video and audio. Open it again and it picks up from the same second. There's nothing to turn on.
How does the AI subtitle generation work?
It uses Whisper speech recognition models that run directly on your machine. No cloud processing, no internet connection required, no data sent anywhere. You pick a model size — smaller is faster, larger is more accurate — and it generates subtitles from the audio on your device.
Is it free to use?
Yes. Glucose is free for everyone. In the future we may introduce a pay-what-you-want model to support development, but it will stay free.
Is Glucose open source?
Yes. Glucose is open source under the EUPL-1.2 license. You can view the source code and contribute on GitHub: https://github.com/rudi-q/glucose_media_player.
What are the system requirements?
Windows 10 or newer (64-bit). The installer is about 4 MB and the app starts fast.
Will there be macOS or Linux versions?
Glucose currently targets Windows. Cross-platform builds may come later — follow the GitHub repo for updates.
