Introducing Subly: AI Captions and Accessibility for Pre-Recorded Video
Publishing video without captions is a reach and compliance problem — mute feeds, ADA/WCAG/EAA expectations, and multi-language audiences all need a caption pass. Subly is an AI-powered accessibility platform for pre-recorded video and audio: captions, transcripts, audio description, translation, and compliance checks in one workflow.
It sits in the caption / packaging layer for teams who need accessible, subtitle-ready media — not generative talking avatars.
What Subly does
Accessibility packaging around caption → check → publish:
- Captions and subtitles — closed captions that meet industry standards for mute and hard-of-hearing viewers
- Transcription and descriptive transcripts — audio-to-text plus screen-reader-friendly transcripts
- Audio description — narrated descriptions of on-screen visuals and actions
- Translation — caption/transcript workflows across a large language set
- Accessibility checker — scan files against WCAG and related practices (captions, contrast, audio description, and more)
- API and editor — integrate transcription/translation, then edit and format subtitles online

Who it is for
Marketing, education, and product teams who publish pre-recorded video and need captions, transcripts, and compliance confidence — especially against ADA, WCAG, EAA, and related frameworks.
Where it fits in a content stack
Subly owns finished or near-finished media → accessible, captioned, compliance-checked package. You still own the story and the cut; Subly compresses subtitle, transcript, and accessibility packaging.
Why it matters now
Accessibility is both a viewer experience and a regulatory expectation. Caption and transcript quality is how video libraries stay usable across mute feeds, classrooms, and public-sector requirements.
How teams typically use Subly
A content team captions a course library and checks WCAG gaps. A brand translates product demos for new markets. An education team adds audio description and descriptive transcripts before publishing.
Quick tips if you try Subly
- Caption before you scale distribution — mute feeds punish silent video.
- Run the accessibility checker on a sample before a big library push.
- Edit critical terms in the subtitle editor — product names and jargon need human eyes.
- Use the API when captions belong inside an internal CMS or LMS.
- Email support@getsubly.com for workflow or compliance questions.
Soft close — related tool
If you also need concept → storyboard → animated or whiteboard explainer / Reels (not talking-avatar presenters), see Scro Explainer. Scro (by NOVAX) is built around approving an AI storyboard before you render — useful when the job is teaching a process, not captioning finished media. Keep Subly as the focus of this intro; Scro is only a related option for storyboard-first explainers.
