IntelliFit AI fitness sensing module concept
IntelliFit · AI Human Health Perception

AI that keeps understanding how people move, eat, and change

Visual AI, multimodal models, and wearable sensing turn real-world movement and nutrition into a personal health intelligence model.

Company Positioning

Not two isolated apps, but one system for understanding human behavior

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.

5,000+

combined beta users across both products

100K+

founder audience and organic launch channel

2 + 1

two app entries and one wearable direction

Application Layer

Two real products entering two high-frequency health behaviors

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.

3,500+ beta users

Movement intelligence

教链 · CoachLink

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.

  • Training plans, execution logs, and cycle progress
  • Movement video analysis and pose-estimation validation
  • Coach operations, client collaboration, and delivery tools

Web and mini-program versions are live, with 3,500+ beta users validating the first entry into movement understanding.

Nutrition intelligence

食探 · FoodLink

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.

  • Chinese meal recognition, portion estimation, and nutrition analysis
  • Personal goals, health profiles, and continuous feedback
  • Logging, analysis, community, and organizational scenarios

The website and mini-program are live, with 2,000+ beta users and a growing base of real meal images and correction feedback.

Perception System

The next step in health management: from manual logging to continuous understanding

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.

01 · Log

CoachLink and FoodLink capture training, meals, and subjective feedback as verifiable behavioral inputs.

02 · Sense

First-person vision, pose estimation, and multimodal sensors reduce logging friction and capture real behavior.

03 · Understand

Movement, nutrition, physical state, and context form a long-term behavior-state-outcome model.

04 · Decide

The system turns understanding into the next meal, workout, or adjustment aligned with the user’s goals.

Technology Roadmap

From application entries to wearable sensing and a human behavior intelligence platform

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.

IntelliFit AI fitness sensing module concept validation

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.

01

Stage 1 · Application validation

CoachLink serves movement intelligence and FoodLink serves nutrition intelligence, validating real users, data, and feedback loops.

02

Stage 2 · Wearable sensing

Explore a clip-on AI fitness sensing module using vision, pose, and multimodal sensor fusion to understand training continuously.

03

Stage 3 · Behavior intelligence

Connect movement, nutrition, rehabilitation, and other signals into a personal health intelligence model that can expand to more human-understanding scenarios.

Founder And Team

A team at the intersection of AI, life science, and high-level training practice

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.

Careers

Hiring early core members in Beijing

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.

AI perception and technical product

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

Founder IP growth and commercialization

Build founder IP into a real commercial asset across content, user conversion, private community, consulting, training camps, live commerce, and partnerships.

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.

How to apply
