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 user’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.

QuantLink's answer:

QuantLink brings data that usually sits behind institutional subscriptions into one free-to-start terminal: AI agents that read primary SEC filings, machine learning factor models, congressional trade tracking under the STOCK Act, 13F institutional holdings, and insider Form 4 activity. Most retail tools stop at price and charts. QuantLink adds the primary-source and modeling layers on top.

QuantLink's answer:

Screeners like Finviz and Koyfin handle price and charts well but stop at the surface. QuantLink pairs a screener and machine learning factor models with primary-source depth: AI analysis grounded in actual 10-K, 10-Q, and 8-K filings, plus congressional, 13F, and insider data in one place.

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.

QuantLink's answer:

Individual investors, retail traders, financial analysts, and finance students who want institutional-grade research without institutional pricing. Focused on US equities.

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.

QuantLink's answer:

We built QuantLink so retail investors could get research tools on par with what professionals use, without the $20,000 Bloomberg Terminal price tag. The filings that matter most, 10-Ks, 10-Qs, and 8-Ks, hold the real business story, but most people never read them. Our AI agents do the reading, and we layered on the data most screeners skip: congressional trades, 13F holdings, and insider activity.

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.

Spatius's answer

TAL Education is one of Spatius’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 platform’s ability to operate in long-term, large-scale production environments.
