Happily Arrived
AI-Powered Event Onboarding
Introducing AI onboarding reduces time-to-value on how event creators start an event page, from a multi-step setup form into a single AI conversation. Describe your event, upload a brief, or forward an old invite, and Arrived AI builds a fully branded, ready-to-publish event page in the same flow.

Output AI-inferred vs. manual
Event pages mostly build from AI
The Problem
How might we help event organizers start their event page without making them fill out every form field before they’ve even seen what they’re building?
First-time users hit real friction:
The Solution
Shaping an agentic, conversational experience that surfaces AI-powered insights to less-technical customers, not adding AI as a feature, but rethinking the interaction model itself:
Research & Discovery
To validate these needs, I ran 5 moderated sessions with event producers and 3 with Happily specialists, then mapped every event type and data point the AI would need to infer versus ask for directly. That mapping uncovered a few consistent patterns:

THE GOAL
Collect only what the AI can’t reasonably infer, and infer everything else. So most users can go from a blank prompt to a finished page without seeing a form field.
Design Process
Started with low-fidelity wireframes to test the core prompt-to-preview concept, then iterated on how much generated content to mark as "inferred". This was also the first project where I built AI tools into my own process, not just into the product.

Testings & Iterations
Part I - CONCEPT TESTING (PROMPT-TO-PREVIEW)
Key Insight: Users trusted the AI-generated draft more when they could see, section by section, what was inferred vs. specified → this directly shaped the "inferred" tag system in the final design.
Part II - GUIDED VS. FAST-PATH TESTING
Key Insight: Confident, repeat-minded users felt slowed down by mandatory guided questions → this led to offering "Build Now" as a parallel fast path instead of forcing everyone through the same sequence.
Design Decisions & Considerations

Project Impact
Faster Time to Preview & Publish
Went from a blank prompt to a full generated site preview in under 90 seconds, on average
Higher Onboarding Adoption
Lifted the amount of new users that complete the setup of a event website
Reflections & Next Steps
Transparency Builds Trust in AI Output
Users didn't need the AI to be perfect. They needed to always know what it had guessed, so they could decide what to double-check.
One Path Doesn't Fit Every User
Confident and cautious users needed genuinely different flows, not just different amounts of hand-holding within the same one.
Designing for AI Structures Is Its Own Discipline
Uncertainty, confidence, and inferred content aren't edge cases in an agentic product, they're the core interaction model. This project pushed me to design for what a system doesn't know yet, not just what it does.
