Spatius features and specs

  • Photorealistic Real-Time Digital Humans
    Bring AI conversations to life with natural lip synchronization, facial expressions, and lifelike 3D characters. Spatius turns generated speech into responsive digital human animation in real time.
  • Cloud-Edge 3DGS Architecture
    Spatius combines lightweight cloud-based motion generation with on-device 3D Gaussian Splatting rendering. This architecture delivers high visual quality without continuously streaming rendered video from cloud GPUs.
  • Stable on Low-Bandwidth Networks
    Instead of transmitting a heavy video stream, Spatius sends lightweight motion data to the client device. This enables stable interactions on constrained, shared, or variable networks and helps prevent frozen or degraded avatar video.
  • Cross-Platform SDKs
    Deploy digital humans across web, iOS, Android, smart terminals, and intelligent hardware. Spatius supports modern browser and native rendering technologies, including WebGL/WebGPU, Metal, and Vulkan.
  • Built for Long-Running, High-Concurrency Use
    Spatius is designed for extended conversations and large-scale production deployments. Its edge-rendering architecture reduces dependence on cloud GPU capacity, enabling predictable costs as usage and concurrency grow.
  • Flexible AI Integration and Custom Avatars
    Connect Spatius to your preferred ASR, LLM, TTS, and real-time communication stack through standard audio-streaming interfaces. Teams can choose ready-made characters or deploy custom-branded 3DGS avatars for their own products.

Linear features and specs

  • User Interface
    Linear provides a clean and intuitive user interface, making it easy for users to navigate and manage tasks.

Possible disadvantages of Linear

  • Pricing
    Some users may find the pricing model a bit expensive, especially for smaller teams or individual users.
  • Limited Customization
    While the default settings are user-friendly, there are limited options for customization compared to some other project management tools.
  • Dependency Management
    Linear's dependency management features are not as advanced as other tools, which might be a drawback for larger projects with complex dependencies.
  • Mobile App
    The mobile app, while functional, lacks some features available on the desktop version, which may impact productivity on the go.
  • Notification Overload
    Users might experience notification overload, which can be distracting, although it is possible to adjust notification settings.

Questions & Answers

As answered by people managing Spatius and Linear.

What makes your product unique?

Spatius's answer

Spatius combines photorealistic 3D Gaussian Splatting avatars with a cloud-edge rendering architecture built specifically for real-time AI interaction. Instead of rendering every frame on cloud GPUs and streaming it as video, Spatius sends lightweight motion data to the userโ€™s device, where the avatar is rendered locally.

This approach addresses visual quality, network reliability, device coverage, and operating cost at the same time. It allows digital humans to remain responsive during long conversations, work across web, mobile, and intelligent hardware, and scale to high-concurrency production environments.

Why should a person choose your product over its competitors?

How would you describe the primary audience of your product?

Spatius's answer

Spatius is built for companies and developers creating AI products that benefit from natural, face-to-face interaction. Its primary users include teams working in AI education, recruiting and interviews, customer service, smart terminals, digital assistants, intelligent devices, and AI companion products.

It is especially well suited to organizations that require long-duration conversations, high concurrency, cross-platform deployment, custom-branded characters, or reliable operation on constrained networks and hardware.

What's the story behind your product?

Spatius's answer

Spatius was created to close the gap between digital human demonstrations and real-world deployment. Many avatar technologies can produce an impressive short demo, but become difficult or expensive to operate when conversations last longer, user numbers grow, or products must run across diverse devices and network environments.

The Spatius team developed its own cloud-edge 3DGS technology to solve these production challenges together. Today, Spatius helps companies turn AI into a more natural and expressive presence, bringing real-time digital humans into education, recruiting, smart devices, customer-facing terminals, and companion applications.

Which are the primary technologies used for building your product?

Spatius's answer

Spatius is primarily built on proprietary 3D Gaussian Splatting technology and a cloud-edge rendering architecture.

Its cloud-based Motion Server converts generated speech into lightweight facial and motion data, while the AvatarKit SDK renders and animates the 3DGS character locally on the client device. Platform technologies include WebGL and WebGPU for web applications, Metal for iOS, and Vulkan for Android. Spatius can receive real-time audio through technologies such as WebSocket, WebRTC, LiveKit, and Agora, and can integrate with third-party ASR, LLM, and TTS providers.

Who are some of the biggest customers of your product?

Spatius's answer

TAL Education is one of Spatiusโ€™s leading customers. Spatius also works with established companies across education, recruiting, smart devices, and AI companion products.

Products powered by Spatius have reached millions of end users and supported tens of millions of digital human conversations, demonstrating the platformโ€™s ability to operate in long-term, large-scale production environments.

  • Freshworks Just Shipped an MCP Gateway Inside Its ITSM Platform. Here's What That Actually Changes.
    Model Context Protocol, for context, is the emerging standard for letting AI agents pull live data from external systems without custom integration code. Freshworks has implemented it as a native layer in Freddy AI, which means agents can now reach into Notion, ClickUp, Linear, Workday, Rippling, and the rest of the enterprise stack โ€” not through brittle webhooks or bespoke connectors, but through a standardized... - Source: dev.to / 3 months ago
  • How to Document and Track Technical Debt
    Issue trackers: GitHub Issues, Linear, or Jira work well because technical debt records live in the same tool as feature work. This makes them easier to pull into sprint planning and keeps the debt backlog visible alongside the feature backlog. The main risk is that debt issues get buried under feature issues without careful labeling and triage discipline. - Source: dev.to / 3 months ago

    Most engineers fail salary negotiations because they use vague statements like "I work hard" or "Iโ€™m a good teammate" instead of quantified, verifiable impact. After 15 years of negotiating offers, Iโ€™ve found that engineers who tie their ask to concrete business outcomes land 30% higher offers than those who donโ€™t.
