Card Nest
Business card scanner and contact manager
Card Nest is an Android and iOS business card scanner and contact manager. Take a photo of a physical business card and Card Nest uses your selected AI provider to extract contact details such as names, phone numbers, email addresses, company names, and addresses. You can review, organize, search, and securely sync your business contacts, then optionally add them to your phone’s Contacts app.

WHAT CARD NEST DOES
Every step from a stack of cards to an organized contact library.
AI extracts the details
Your selected AI provider (OpenAI or Google Gemini, with your own API key) reads each card and turns it into structured contact information: names, companies, phone numbers, emails, and addresses.
Organize your contacts
Every scanned card becomes a clean contact record with favorites, tags, notes, and support for multiple phone numbers and email addresses.
Search everything instantly
Find any contact by name, company, title, phone, email, address, or even text printed on the original card.
Securely synced across devices
Your library is stored privately in the cloud with per-user security. Sign in on a new phone and every card and contact is right where you left it.
Export to your phone
Optionally save any Card Nest contact — or many at once — straight into your phone’s Contacts app.
SIGNING IN WITH GOOGLE
Google Sign-In
Card Nest uses Google Sign-In to authenticate your Card Nest account and, when authorized, receive basic profile information such as your name, email address, and profile picture. Card Nest does not use Google Sign-In to access your Gmail, Google Drive, Google Calendar, or Google Contacts.
You can also sign in with an email address and password instead. Details are in the Card Nest Privacy Policy.
