Exify — Case Study
Exify is an AI‑assisted co‑parenting app. I led brand + product, designed the core flows, and shipped the MVP with React Native and Supabase. The experience focuses on fast onboarding, healthy communication, and a sustainable referral flywheel.
Overview
Goal: lower the friction of co‑parent communication while providing receipts and summaries you can trust.
Scope
MVPOnboarding, Messaging, Calendar, Docs, Referrals
Design
Dark brutalistBold type, systemized spacing
AI
Tone + SummariesRewrite assist + weekly digest
Product Highlights
Core flows that make collaboration calmer and faster.




FastStart: 2‑minute onboarding with progressive profile completion.
Calm Messaging: Read receipts, mini‑tasks, and reply nudges.
Referral Loop: 10% recurring commission via Stripe/RevenueCat.
AI Systems
AI assists tone, reduces escalations, and creates audit‑ready summaries.
Tone Coach: Rewrites sensitive messages into neutral, specific, and respectful phrasing.
Weekly Digest: Summarizes decisions and action items; exports to PDF.
Safe Send: Flags risky language before sending.
// Pseudocode — tone rewrite
async function rewrite(msg){
const sys = "You are a co‑parenting tone coach: neutral, specific, respectful.";
const prompt = `${sys}\nRewrite this message to reduce conflict: ${msg}`;
const out = await llm.generate(prompt);
return clampLength(out, 240);
}
Design System
Small token set for max clarity and predictability.
