Sonix is an AI-powered transcription platform that converts audio and video into text, with automatic speaker identification, timestamps, and translation into more than 54 languages. Beyond raw transcripts, it generates subtitles and captions for video, along with AI-powered summaries, chapters, and sentiment analysis. Sonix offers a web-based editor for cleaning up transcripts, a companion mobile recorder app, an API for developers, and integrations with tools like Zoom, Microsoft Teams, Adobe Premiere, and Zapier. Pricing ranges from pay-as-you-go at $10/hour to monthly plans starting at $25/month, with HIPAA-compliant enterprise options for legal, healthcare, and media organizations.
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.
