Learn SignStream
What is SignStream?
SignStream is Signapse’s AI sign language translation product, designed for organisations that need to deliver sign language translations programmatically and at scale.
It takes spoken or written content and converts it into AI-generated sign language video, enabling real-time and on-demand accessibility experiences through a production-ready API.
SignStream is built for organisations that require speed, reliability, and scalability.
What Can You Do with SignStream?
With SignStream, organisations can:
- Translate spoken or written content into sign language using AI
- Deliver sign language translations in real time or on demand
- Integrate sign language accessibility directly into their own systems
- Support high-volume and live accessibility use cases
- Build scalable, automated accessibility solutions
SignStream is designed for B2B and enterprise use, where accessibility needs to work at scale.
How SignStream Is Accessed
SignStream is accessed primarily through the SignStream API.
| Access Method | Purpose | Who It’s For |
|---|---|---|
| SignStream API | Production integration | Organisations, developers, technical teams |
| SignStream Demo Platform | Demonstration only | Evaluating AI output and capabilities |
SignStream API (Primary Product)
The SignStream API allows organisations to integrate AI sign language translation directly into their own platforms, services, or workflows.
Access to the API is provided via an API key, with full setup guidance available through the Developer Portal.
What the API Enables
| Capability | Description |
|---|---|
| Real-time translation | Live sign language translation from spoken or written content |
| On-demand translation | Instant AI-generated sign language video |
| System integration | Embed accessibility into existing products or services |
| Scalability | Support high-volume or continuous use cases |
SignStream Demo Platform (Demonstration Only)
The SignStream demo platform is designed solely to demonstrate the capabilities of the SignStream API.
It allows organisations to try the AI translation experience and understand the type of sign language output SignStream produces before discussing a production integration.
The demo platform is not intended for production use and should not be used as a long-term or scalable solution. It runs on limited resources and is intentionally slower than the production SignStream API.
What the Demo Platform Is For
- Try AI-generated sign language translations
- Explore the style and quality of the AI output
- Understand how spoken or written content is converted into sign language video
Demo Limits
| Limit | Amount |
|---|---|
| Maximum words per message | 20 |
| Maximum words per week | 100 |
| Maximum words per month | 400 |
Organisations looking to deploy SignStream in real-world environments should use the SignStream API.
