About
Dolphin is a secure, invite-only mobile platform built exclusively for the Chadwick International community.
Tired of messy group email threads for buying and selling? Dolphin replaces that chaos with a clean, organized experience — all from your phone.
DOLPHIN MARKET
Buy and sell items within the CI community. Our transparent Queue System lets buyers join a waitlist so everyone can see their position — fair, first come first served. Upload a photo and let our built-in AI automatically generate the title, description, and tags for your listing.
SMART LOST & FOUND
Lost something on campus? Found an item in the hallway? Snap a photo and post it. Dolphin's AI automatically generates descriptions and smart tags, making it easy for anyone to search and find their missing belongings.
F&S LOUNGE
A private community board for Faculty & Staff to share tips, ask questions, and post about events — organized with categories, likes, and comments.
IN-APP MESSAGING
Chat directly within the app to negotiate prices, claim a lost item, or reply to a post. No need to share personal phone numbers or emails. Real-time push notifications keep you in the loop.
SECURE & PRIVATE
Only @chadwickschool.org Google accounts can log in. The app automatically detects whether you are a student or faculty/staff member and tailors your experience accordingly.
Built by CI, for CI.
