Overview
Spilk is an AI-powered app that analyses personal chats — WhatsApp, Instagram, Telegram — and turns them into emotional insights: response times, conversation balance, mood patterns.
The product had real analytical power but an interface that hid it. My work covered the complete app redesign: a calmer onboarding, a legible data-visualisation language and a refreshed brand.
Challenge
Chat data is intimate. The previous experience asked for trust before it earned it — dense screens, unclear charts and an onboarding that explained too little, too late.
- Users didn’t understand what the app would do with their conversations.
- Insight screens read as raw statistics rather than stories.
- The visual identity felt technical, not personal.
Approach
Onboarding that earns trust
The new flow greets users personally — “Hey! Olivia and Marta” — and explains each step of the analysis before asking for anything. Privacy language moved from fine print to first screen.
Data as narrative
Response-time arcs, weekly rhythm rings and side-by-side comparisons were redesigned around one principle: every chart should answer a human question, like who replies faster — and is that changing?
A warmer brand
Deep violet grounds the interface; coral and soft lilac carry the data; a rounded wordmark makes the product feel like a companion rather than a lab.
Outcome
Trust made visible
Privacy explained upfront; consent became part of the experience, not a hurdle.
Charts people read
Usability sessions confirmed users could interpret every insight without help.
A brand with warmth
New identity carried consistently across onboarding, data and marketing screens.
