Automatic caption generation
Convert speech into accurate captions with speaker recognition and contextual understanding.
AI Video Captioning, Subtitling and Translation System
Make videos accessible and global
Trusted by clients worldwide
Context
A large portion of video content is consumed on mute, especially on mobile and social platforms. At the same time, audiences expect content in their native language. Without captions and translations, even high-quality videos lose visibility, engagement, and usability. As video production increases, manual captioning workflows struggle to keep up with volume and turnaround expectations.
Who this is for
We work best with teams who treat software as an operating system for the business, not a one-off project.
Good fit
- Content creators and video platforms managing frequent uploads
- Media and entertainment companies distributing global content
- E-learning and course platforms requiring multilingual access
- Marketing and social media teams optimizing video reach
- Enterprises managing large and growing video libraries
Not a fit
- Teams with very low video production volume
- Businesses needing only manual captioning services
- Projects without multilingual or accessibility requirements
- Users looking for basic standalone subtitle tools
- One-off video processing without ongoing workflows
The operating reality
Why video content misses its audience
Teams often rely on manual captioning and translation processes that are slow, expensive, and difficult to scale. Subtitle quality varies across languages, timing issues reduce readability, and inconsistent formatting affects viewer experience. Managing multiple tools for transcription, translation, and editing adds operational complexity. As content libraries grow, delays in captioning slow down publishing cycles, limit accessibility compliance, and reduce global reach. Without a structured system, videos fail to reach audiences who depend on subtitles or prefer localized content.
How this is usually solved
Common approaches
Where it falls short
Common approaches
- Writing captions manually and syncing them to video timelines
- Outsourcing subtitle translation to external agencies
- Using separate tools for transcription, translation, and editing
- Editing subtitle files individually for each video
- Managing subtitles without centralized tracking or workflows
Where it falls short
- High operational cost for captioning and translation
- Slow turnaround delaying video publishing
- Inconsistent subtitle quality across languages
- Limited ability to scale across large video libraries
- Difficulty meeting accessibility and compliance standards

Improved accessibility and compliance with standards
Faster and more scalable subtitle production workflows
Frequently asked questions
Straight answers procurement and engineering teams ask before a build kicks off.
The system can generate commonly used subtitle formats such as SRT and VTT, along with other formats required by your publishing workflow. Custom export requirements can also be incorporated into the implementation.
Accuracy depends on factors such as audio quality, accents, background noise, speaker overlap, and terminology. We combine AI transcription with validation and human review workflows so teams can correct important errors before publishing.
Yes. The workflow can generate subtitles across multiple target languages and process them in batches. Language coverage and translation workflows can be configured around your content requirements.
Yes. Human review can be included before publication. Editors can review transcription, translation, timing, formatting, and terminology, then approve the final subtitle files.
Yes. Batch processing and automated pipelines can be designed for large and continuously growing video libraries. Integrations with storage systems, video platforms, CMS tools, and APIs can also be added to reduce manual processing.
