Seizafe - Epilepsy Alert for YouTube™ Extension

Seizafe flaunts a life saving algorithm and a beautiful user-experience designed to warn you before any rapidly flashing scenes in YouTube™ videos.

Countless YouTube™ videos these days have no warnings whatsoever for any impending Epileptic content, thus imposing an unforeseen danger upon those among us who have the condition. Seizafe is (specially 🌼) designed for people with Photosensitive-Epilepsy / any other neurological disorder, keeping you safe from unexpected jarring/flashing/bright transitions in videos which could cause deadly Photosensitive seizures. Since anyone can develop epilepsy, Seizafe is an ideal solution to narrow down the chances of you developing the condition, even as a healthy individual.

The sensitivity of the algorithm to identify flashing content can be adjusted to your preference via the sensitivity controls in the pop-up menu on our extension.

Seizafe is ideal for public computer labs/kiosks/lounges eg. in hotels, schools, hospitals, offices, airports etc. Public safety is a very important value to keep those around us safe, even from the simple but unexpected dangers of videos.

Seizafe is one Chrome Extension with a greater story behind it. Be safe. Be kind.💜

Macalvand (ID: 00000061ca2acc1e) Voted 4 ★ - Updated 02/25/2023 Works well, very sensitive, perhaps too sensitive. Even on the low sensitivity the video auto-pauses all the time while watching online lectures with fast slide transitions.

Łukasz Martynowicz (ID: 000000530dd9a3c9) Voted 5 ★ - Updated 12/09/2022 Wow! This is a game changer for me. I was hoping for this kind of extension for years, and it's finally here. Just installed it and tested it (with the help of my wife, for obvious reasons) on a video which caused a serious problem once before, and it worked like charm. Now please expand it to streaming services. Having it working on sites like Disney+ or HBO would be so, so great. Kudos to you!

Aaron Delgado (ID: 000000ce9df4e60c) Voted 4 ★ - Updated 05/07/2022 Works beautifully on my laptop but I've been trying to get it to work on my Android Phone and/or Android Tablet and nothing's working. Is it not compatible?

James_ugx (ID: 000000fe9b209d6c) Voted 5 ★ - Updated 03/03/2022 This works perfectly well, it's so sensitive... It's helpful, I recommend...

Pacsonic 9000 (ID: 000000eb49d25f2c) Voted 4 ★ - Updated 02/16/2022 Almost 5 stars. The only problem is that when you try to play a YouTube Shorts video, the extension places a big purple exclamation mark circle over the short and adds a purple hue to the video and there's no way to close it as the shorts plays. It works as advertised for regular videos. Please fix the YouTube Shorts bug I mentioned reuelthecloudwalker. Once you do, then I'll add a star.
