Not a prettier chatbot.
This affected millions of Lowe's customers navigating high stakes, high anxiety purchases. A wrong part means a second trip, a cancelled installation, or a flooded kitchen.
The goal was dual: deflect support load AND improve customer confidence. That two sided brief made this one of the most constrained projects I've worked on.
The project started as one thing. Became another.
"Add an AI assistant. Help customers find products faster."
Before designing a single chat bubble, I asked: were customers failing to find products. Or were they never confident enough to commit? That question changed everything.
Customers weren't failing at finding products. They were failing at trusting their choice. The solution became: an assistant that interrogates gently, surfaces evidence, and never bluffs.
Meet Priya.
Searched "faucet leak." 847 results. Closed the app. Called a plumber. Paid ₹3,200 for a ₹600 part. Competent. Willing. Just didn't trust she'd pick the right part.
Priya is the modal Lowe's customer. Not confident enough to commit. Traditional search doesn't close that gap. Two questions and one part with a 98% fit badge does.
I sat with people who answer these questions for a living.
Research across customers mid project, store associates (the human version of MyLow), and support agents. Every insight mapped to a design decision:
"I don't know what the part is called". Most common customer response
Scoped chips replace open text. "It's leaking" not "Moen 1222 cartridge."
Match customer vocabulary. They know the symptom. Not the SKU.

Three directions. One right answer.
Free form text. Maximum flexibility.
Rejected → Same problem, different box.Filter questions → product list.
Rejected → Still not advice.Chips → diagnosis → product card with fit confidence.

Every screen answers three questions.
Problem. Decision. Why it matters. If a screen couldn't answer all three, it didn't ship.

Five I'd defend.
The bet: less flexibility = more completion. Intent accuracy improved significantly.
The bet: rules based narrowing is safer and auditable. Generative v2 came after trust was established.
The bet: single opinionated pick beats comparison list. Add to cart rates higher with one card.
The bet: admitting uncertainty builds more trust than always answering. Handoff state scored highest.
The bet: in progress experience affects perceived quality. Thoughtful streaming scored higher than instant pop in on identical answers.
What changed.
MyLow shifted how the team thought about the assistant. From "bolted on chatbot" to a decision making layer across the whole shopping journey
Honestly.
What surprised me: the hardest problem wasn't the AI, it was teaching people to trust it. The graceful handoff did more for adoption than any clever flow.
What I'd do differently: instrument conversation quality metrics from day one. Hallucination rate, recovery from misunderstanding, time to confidence. Those are the real UX metrics in an AI product.
The uncomfortable question: when does a personalised assistant become a filter bubble? I don't have a clean answer. Worth someone asking.
