What Subly is

Subly is a browser-based platform for checking and improving accessibility in prerecorded video and audio. Its AI agent reviews media frame by frame for colour contrast problems, flashing content, missing captions, audio descriptions and other WCAG-related issues, then provides a report. The platform can create captions, transcripts, translations, audio descriptions, trigger warnings and contrast fixes. An editor lets users review and refine these changes, with team collaboration before publishing. Professional caption proofreading, translation polishing and audio descriptions are also available. Media can be added through URL uploads, Zoom syncing, OneDrive and SharePoint integration, an API, or imports from tools such as Veed and Adobe. The accessibility agent supports MP4 and MOV video plus MP3, M4A and OGA audio, but not live media. Subly says transcription and subtitle translation cover 255 languages. Subtitle downloads include SRT, VTT, TTML and XML. Paid access includes a 7-day trial note, while no free plan is offered.
