DataPizza, a Carnegie Mellon University-affiliated venture where AI researcher Dr. Deva Ramanan serves as a board advisor, recently announced the next phase of its platform development. The well-recognized startup, born out of research at CMU’s Robotics Institute and driven by industry collaboration, has built its reputation on better interfaces for AI model training and data annotation. DataPizza’s flagship project was developed in partnership with a major U.S. tech giant’s generative AI initiative, the U.S. tech giant’s video model, and the company is now expanding its human-in-the-loop data annotation tools to embrace upcoming visual-language AI model platforms. Building on the success of its video annotation system, DataPizza is developing a new text-to-video model training and annotation platform that will extend its human-and-AI collaboration approach into even more cutting-edge domains. This next-gen platform will allow users to input text descriptions to guide AI-generated video content – a formidable UX challenge that Lead Designer Yu Tong Tiffany Ling (“Tiffany Ling”) is tackling head-on, already mapping out user workflows and interactive mockups for an intuitive interface.
Pioneering Human-in-the-Loop Tools for Generative AI
DataPizza’s current platform, designed for the U.S. tech giant’s video model’s video data, exemplifies the venture’s human-in-the-loop ethos. Under Tiffany Ling’s design leadership, the custom annotation interface enables human annotators and AI algorithms to work hand-in-hand: AI-generated suggestions are presented to users for verification or correction. This AI-integrated workflow accelerates the tedious task of labeling images and video while preserving accuracy. The company reports that labeling accuracy increased from approximately 70 % to over 90 %, and annotation efficiency nearly doubled, following the implementation of Tiffany Ling’s design innovations. Such improvements are critical for the U.S. tech giant’s video model team and DataPizza’s research goals, enabling higher-quality data to train vision models in less time. The interface Tiffany Ling built balances efficiency with clarity: it’s clean, logical, and responsive, allowing annotators to accept or refine AI-proposed labels rapidly. She introduced thoughtful UX features – like context-aware tooltips and color-coded confidence indicators – to streamline workflows and reduce cognitive load on users. Just as importantly, Tiffany Ling established a cohesive UI design system across all components (from dashboards to controls), ensuring a consistent user experience and an easily scalable architecture as new features are added. This blend of usability and scalability forms a backbone for DataPizza’s next phase of development.
Now, as DataPizza ventures into text-to-video and other visual-language AI platforms, Tiffany Ling’s user-centric design approach remains front and center. The upcoming tools will continue to embed advanced AI into the user experience in a human-friendly way – reflecting DataPizza’s core mission of keeping people in the loop of AI creation. The project’s multi-modal challenge (merging natural language input with visual output) plays to the team’s interdisciplinary strengths. “Even as the underlying technology grows more complex, we ensure the end user’s experience remains intuitive,” said Tiffany Ling, Lead UX/UI Designer at DataPizza, emphasizing her vision for human-centered AI design. “Our goal is to build AI tools that feel like natural extensions of the user – empowering people to work with AI as creative partners, not just end-users.”
Tiffany Ling: Driving Human-Centered Design Innovation
As DataPizza’s creative and strategic design lead, Tiffany Ling has been instrumental in shaping the platform’s direction from day one. She joined DataPizza at its inception as the founding UX/UI Designer, architecting the entire user interface and design language from the ground up. From visual style to interaction patterns, Tiffany Ling set the product’s UX vision and has collaborated closely with engineers to bring that vision to life. Internally, she’s often regarded as the “creative heartbeat” of DataPizza’s product development – a testament to her influence beyond pure design work. In practice, Tiffany Ling’s role blends design execution with product strategy: she aligns cross-functional efforts spanning design, engineering, and user training, effectively acting as a key product leader for the company. She works in agile loops, rapidly turning user feedback into iterative prototypes in a matter of days, which has fostered continuous improvements and a tight-knit, collaborative development culture.
Tiffany Ling’s design contributions are both visionary and hands-on. In addition to the annotation platform, she has spearheaded the creation of new product features and end-to-end user experiences. Her portfolio ranges from building an AI-powered resume builder web platform to crafting interactive mockups for AI-driven learning apps and workflow tools. In the resume builder project, for instance, she was the sole UX designer leading a team of interns in a comprehensive redesign, significantly elevating the site’s user engagement. This breadth of experience – from enterprise AI systems to consumer-facing applications – showcases Tiffany Ling’s versatility in integrating advanced technology with user-centered design. No matter the domain, she focuses on intuitive UI architecture and features that meaningfully enhance how users accomplish their goals.
Beyond her work at DataPizza, Tiffany Ling’s cross-disciplinary profile has earned her international recognition. She is the recipient of multiple prestigious design awards, including a Red Dot Design Award (2023) for her project “XYG Window”, as well as the Top Design Award (2022) and a Creative Communication Award (C2A, 2022) for an innovative interface redesign project. On the research front, Tiffany Ling co-authored a paper on DataPizza’s human-in-the-loop video annotation methodology that was presented at CVPR 2024, one of the premier global AI conferences. (It’s exceedingly rare for a UX designer to contribute to CVPR, underscoring how her work bridges design and cutting-edge AI.)
DataPizza’s latest announcement signals not only a new chapter for its AI platform, but also a broader vision for human-centered AI in industry and academia. By coupling advanced AI capabilities with thoughtful user experience design, the company aims to make training and interacting with AI models more accessible, efficient, and engaging. With Tiffany Ling leading product design, DataPizza is poised to define how humans collaborate with AI, turning complex machine learning workflows into streamlined, empowering experiences for creators, researchers, and everyday users alike.
