SANA – AI CHATBOT
UX and Conversational AI Concept for a Growing Global Wellness Market
DESIGNING CLARITY THROUGH CONVERSATION
Sana is an AI-powered supplement guide created as part of my Stanford UX and AI course. It translates the complexity of nutritional decisions into a warm, intuitive and human experience built around the brand universe of Sunday Natural.
The global supplement market is enormous. More than 70 percent of adults take vitamins regularly and the industry is expected to reach well over 300 billion dollars in the next few years. People are trying to make healthier choices but are overwhelmed by conflicting information, overlapping ingredients and dosage questions. Sana was created to bring clarity into this daily confusion and spark confidence where uncertainty was the norm.
Self-initiated project created for the Stanford course UX/UI Design for AI Products.
CHALLENGE
This project began as a self-initiated exploration during my Stanford course on UX/UI Design for AI Products.
I observed that many people were overwhelmed by the complexity of nutritional supplements, unsure which ingredients overlap, what combinations are safe, and how much of each nutrient they actually need.
Understanding supplements is difficult. People want to improve their health, but most struggle to interpret symptoms, evaluate ingredients and understand safe combinations. In my environment I saw the same pattern again and again. Friends and family trying to self manage fatigue, hormonal imbalance, digestive issues or low energy with supplements. Many of them were also combining products and had no idea if they were exceeding recommended daily intake.
This confusion inspired the challenge for this project.
How might an AI experience help people understand what their body needs without pressure, fear or guesswork.
Sunday Natural was the perfect reference brand for this concept. The company is known for purity, science driven formulations and a calm, trustworthy aesthetic. It offered the right environment to explore how design and AI could transform a complex topic into something understandable, supportive and emotionally intelligent.
My goal was to design an AI-powered experience that brings clarity, trust, and empathy to this decision process.
INSIGHTS & APPROACH
I started with a simple question:
How might we make AI feel like a mentor, not a machine?
Through research and observation I discovered three central human needs in this space.
People want clarity instead of overwhelming choice.
They want warmth and emotional presence instead of technical jargon.
They want control instead of automated assumptions.
These insights shaped the core principles of the product.
Ask less and mean more.
Explain before you recommend.
Write like you listen.
Help to understand without overwhelming them.
EXECUTION
“Sana” — from sanare, Latin for “to heal” embodies a calm, knowledgeable guide that listens first and advises second.
Flexible Input
The design accepts:
Symptoms, Goals, Diet preferences, Conditions, Medications, Lab results via upload
This flexibility was essential for users with different levels of health knowledge.
Tone and Emotional Design
Sana uses warm and concise language. She acknowledges feelings. She avoids repetition. She asks only what she needs to provide clarity. She offers choices without pressure.
The tone mirrors Sunday Natural’s careful and human approach to wellbeing. It feels gentle, supportive and trustworthy. The experience resembles a conversation with a capable friend, not an automated sales tool.
IMPACT AND EVALUATION
Although Sana is a concept piece created during my Stanford training, it received the highest possible evaluation for its strategic clarity, brand alignment and emotional intelligence.
“Sana is a perfect fit for Sunday Natural. The tone is direct and accessible and the conversation is geared toward resolving real user questions. You applied the chatbot model well to a specific need.”
Instructor Feedback: Luis García Maillo, Stanford Online
This project demonstrates how a brand can expand its digital experience through intelligent conversation.
Consumers increasingly expect personalised, science backed guidance. Sana shows how design can bridge the gap between nutritional knowledge and human understanding.
Health decisions are deeply emotional. Sana makes them feel understandable.
REFLECTION
This project strengthened my belief that designing for AI is ultimately designing for people. The intelligence of a system is not measured in data volume but in the quality of the relationship it builds.
Good UX makes technology feel simple.
Great UX makes it feel human.
Working on Sana allowed me to combine emotional design with structured logic and to explore how brand identity can extend into conversational behaviour. It is one of the most inspiring aspects of designing for AI.
