Seamless Accessibility
All Media Accessibility Covered — Frame by Frame
Manual checks rely on the human eye, prone to errors and missed issues, and video platforms can’t fix everything. Subly catches and fixes every frame.
Captions
Checks if captions are in the video, then generates open and closed captions in 100+ languages.
Transcriptions
Automatically generates transcripts in 100+ languages. For descriptive transcripts, request our expert team to help as an alternative format.
Colour Contrast
AI checks WCAG compliance for text in videos and captions, flags issues, and allows colour adjustments.
Flash Warnings
Detects unsafe flashing, flags risks, and adds disclaimers at the beginning of the video.
Text Clarity & Vocabulary Complexity
Checks sentence readability, flags complex words and jargon, suggests clearer alternatives, and ensures accessibility by analysing structure and vocabulary.
Audio Descriptions
Our expert team creates standard and extended Audio Description for videos to support visually impaired viewers and listeners.
Localisation & Translation
Translate into 100+ languages and use the editor to clearly see the original and translation. Work on multiple translations at once. Request our expert team to help if you don't speak the language.
