What is Subly?

Subly is an accessibility platform focused on catching and fixing accessibility problems in pre-recorded video and audio before it goes live. An AI-powered checker scans content frame-by-frame against standards including WCAG, ADA, and EAA, flagging not just missing captions but also colour-contrast problems and flashing content that could trigger seizures, and produces compliance reports mapped to frameworks like WCAG 2.1, EN 301 549, and the ADA/ACA. On the content side, Subly generates closed captions and subtitles in over 100 languages with an online editor for corrections, can produce audio descriptions for visually impaired audiences, and supports uploads from Zoom, YouTube, Vimeo, and Adobe as well as OneDrive/SharePoint integration. A Subly API allows organizations to embed accessibility checking and captioning into their own publishing pipelines, making it aimed more at enterprises, agencies, and educational institutions with compliance obligations than individual creators wanting quick captions.
