Spatius is next-generation real-time digital human infrastructure that enables AI to communicate through natural, expressive digital characters rather than text and voice alone. Companies can use Spatius across AI education, recruiting interviews, customer service, smart terminals, and companion products to create more engaging and lifelike user experiences.
Powered by its self-developed cloud-edge 3DGS technology, Spatius addresses visual quality, deployability, and cost at the same time. The product runs across web, mobile, and intelligent hardware, remains stable on constrained networks and a wide range of devices, and supports long-duration, high-concurrency interactions at predictable costs.
Spatius currently serves TAL Education and other leading customers in the education, recruiting, smart devices , and AI companion sectors. These products have reached millions of end users and supported tens of millions of digital human conversations, helping customers take real-time digital humans from demos into long-term, large-scale production.

DevPik's answer
DevPik is a free, open-access platform โ we don't have traditional "customers" with contracts. Our users are individual developers, freelancers, and small teams from around the world who use our tools daily as part of their workflow. Since launch, DevPik has served developers across 50+ countries, with the strongest usage from the United States, India, United Kingdom, Germany, and Pakistan. We're used by independent developers, agency teams, and students at universities who need quick, reliable developer and AI tools without enterprise pricing.
Spatius's answer:
TAL Education is one of Spatiusโs 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 platformโs ability to operate in long-term, large-scale production environments.
DevPik's answer
DevPik is the only developer tools platform that combines 50+ traditional developer utilities (JSON formatters, regex testers, Base64 encoders) with AI-powered tools (meta description generators, cover letter generators) โ all completely free, with no signup, no account, and no usage limits. While competitors like CodeBeautify and FreeFormatter are cluttered with ads and stuck in 2015 UI, and AI tool platforms like Grammarly and Copy.ai force you to create an account before doing anything, DevPik gives you instant access to everything. Open the page, use the tool, get your result. Zero friction.
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 userโs 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.
DevPik's answer
Three reasons: First, no signup required โ every tool works instantly in your browser. Competitors like Grammarly, Canva, and Quillbot require account creation before you can do anything. Second, DevPik combines developer tools and AI tools in one place. You don't need to bookmark 10 different sites for JSON formatting, regex testing, text conversion, and AI-powered content generation. Third, it's genuinely free with no hidden paywalls โ no "you've used your 3 free tries, now pay $9.99/month" walls that most AI tool sites throw at you.

DevPik's answer
Web developers, software engineers, full-stack developers, freelance developers, technical SEO professionals, and content creators who need quick access to everyday developer utilities and AI-powered productivity tools. Secondary audiences include students learning to code, startup founders building MVPs, and non-technical professionals who need tools like cover letter generators or text formatters without dealing with complex software.
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.
DevPik's answer
DevPik was born out of frustration. As a developer, I was tired of Googling "JSON formatter" or "Base64 encoder" and landing on ad-infested sites with popups and outdated interfaces โ or worse, tools that demanded an account just to paste some text. I started building the tools I actually needed: fast, clean, free, no signup. What began as a handful of utilities grew into 50+ tools across 8 categories. In April 2026, DevPik became one of the first developer tool platforms to integrate free AI-powered tools using open-source LLMs โ bringing AI meta description generation, AI cover letter writing, and more to developers without charging a penny.
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.
DevPik's answer
DevPik is built with Next.js (React) for the frontend, deployed on Vercel for global edge performance. The backend uses Supabase (PostgreSQL) for blog content and data management. AI-powered tools are built using the OpenRouter API, connecting to free open-source LLMs. All static tools (JSON formatters, text converters, regex testers) run entirely client-side in the browser โ no data is sent to any server, ensuring complete privacy. The site is optimized for Core Web Vitals and scores 90+ on Lighthouse.
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.
