Visual AI, multimodal models, and wearable sensing turn real-world movement and nutrition into a personal health intelligence model.
Company Positioning
IntelliFit is building a next-generation AI human health perception system. We enter frequent, verifiable movement and nutrition scenarios through CoachLink and FoodLink, then use wearables to capture continuous real-world signals.
Application layer: CoachLink understands training and coaching delivery; FoodLink understands eating behavior and nutrition feedback.
Perception layer: a compact AI fitness sensing module continuously captures movement, training, and body signals.
Intelligence layer: long-term behavior-state-outcome feedback creates a personal health model that changes with the user.

Application Layer
CoachLink and FoodLink are not the endpoint. They are application entries into a broader human behavior perception system, solving today’s problems while generating the real feedback required for future health intelligence.
Movement intelligence
An AI movement training system for athletes, coaches, and studios. It connects planning, training logs, movement analysis, and coach operations so training can be understood, reviewed, and continuously improved.
Web and mini-program versions are live, with 3,500+ beta users validating the first entry into movement understanding.
Open CoachLinkNutrition intelligence
An AI nutrition management system for individuals and organizations. It combines food recognition, nutrition analysis, and personalized guidance to understand each meal with less friction and connect eating behavior to long-term goals.
The website and mini-program are live, with 2,000+ beta users and a growing base of real meal images and correction feedback.
Visit FoodLinkPerception System
Traditional health apps wait for users to enter data. We want AI to sense behavior in the real world, understand physical state, and recommend the next executable action.
CoachLink and FoodLink capture training, meals, and subjective feedback as verifiable behavioral inputs.
First-person vision, pose estimation, and multimodal sensors reduce logging friction and capture real behavior.
Movement, nutrition, physical state, and context form a long-term behavior-state-outcome model.
The system turns understanding into the next meal, workout, or adjustment aligned with the user’s goals.
Technology Roadmap
This is not a device bolted onto two apps. It is a staged path: validate users and scenarios, reduce sensing friction, then build a long-term model of human behavior across contexts.
Hardware concept · In validation
A compact AI fitness sensing module can clip onto workout clothing or equipment as an entry point for movement and training understanding. Its sensors and scenarios remain under validation.
CoachLink serves movement intelligence and FoodLink serves nutrition intelligence, validating real users, data, and feedback loops.
Explore a clip-on AI fitness sensing module using vision, pose, and multimodal sensor fusion to understand training continuously.
Connect movement, nutrition, rehabilitation, and other signals into a personal health intelligence model that can expand to more human-understanding scenarios.

Founder And Team
IntelliFit starts from the founder’s AI and life-science research, serious strength-training practice, content reach, and the ability to build products with real users—not from an abstract health concept.
Validate real needs in apps before expanding wearable sensing.
Build behavior-state-outcome feedback before personal models.
Make guidance executable before asking the system to understand more.
Founder / AI & Product
PhD student at Peking University’s Academy for Advanced Interdisciplinary Studies, with an automation background from Nanjing University of Aeronautics and Astronautics. He works across AI for Science and multimodal intelligence, while bringing serious strength-training practice, strong execution, and first-hand judgment on training methods, body management, and real user needs into product building.
Personal websiteWeb Full-Stack & Agent Delivery
Known as Jinhui, he writes technical articles and contributes to OpenMCP and slidev-ai, winner of Alibaba Best App Award. He provides web full-stack development plus frontier Agent R&D and iteration support. Hobbies: fitness, coffee, cycling, and coding.
Personal websiteBackend & Infrastructure / Performance
Ya Ning focuses on reliable backend systems and AI infrastructure, covering backend deployment, cloud-native infrastructure, performance tuning, and reliability engineering. His work spans Go, Kubernetes, observability, and high-concurrency service practices to keep core product systems available and efficient.
Personal websiteCareers
We are building an early AI + fitness and health company with real products, real users, early revenue, and active B2B opportunities. The bottleneck is not a lack of ideas; it is finding people who can own work and close loops.
In-person collaboration in Beijing matters. Product iteration, user feedback, content experiments, and commercialization all need high-frequency communication and people who can own a track over time.
Build CoachLink and FoodLink while advancing movement video understanding, pose estimation, multimodal sensor fusion, wearable validation, and B2B delivery.
Computer vision, multimodal AI, frontend, full-stack, or hardware experience
Able to turn real scenarios into independent demos
GitHub, papers, competitions, hardware, or shipped work are strong pluses
Build founder IP into a real commercial asset across content, user conversion, private community, consulting, training camps, live commerce, and partnerships.
Plan and review Douyin, Xiaohongshu, and Bilibili content
Design IP monetization and conversion paths
Revenue-share mechanisms can be discussed for clear commercial contribution
Based in Beijing and able to work together offline
Senior undergraduates or graduate students with most coursework completed
Real projects, shipped work, accounts, demos, or GitHub
Interest in AI, fitness, health, founder IP, commercialization, or early startups
Collaboration model
We usually start with a 3-7 day project-based trial so both sides can evaluate fit. High offline commitment can be paid as an internship; online or low-frequency work is better matched to workload, project delivery, and results. Strong long-term collaborators may enter core-member evaluation, with exceptional candidates considered for future partner roles.
Please send your resume, project experience, portfolio, account links, demos, or GitHub to the personal email first. You can also add the work WeChat directly. Referrals of strong candidates are very welcome.
Collaboration
We welcome collaboration with coaches and sports organizations, enterprise and university health programs, computer-vision and wearable partners, and early teammates who want to build the system with us.
Training plans, movement analysis, coaching delivery, studios, and university sports.
Employee health, campus health, real-world pilots, and joint product validation.
Visual understanding, 3D pose estimation, multimodal sensors, and wearables.
