Core51

Core51 is a secure messenger designed for business communication. Keep your work conversations separate from personal chats and communicate with colleagues, customers, partners, and clients in one dedicated app. Messages in Core51 are protected with end-to-end encryption, so your business conversations stay private. Core51 also lets you download chats and verify their integrity, providing a reliable record of important communication. Your CoreID gives you a simple public identity that you can share with others, use on a business card, or provide instead of your personal contact details. Core51 focuses on the features that matter for everyday business communication: secure messaging, clear contacts, simple file sharing, and easy access to conversation history. No unnecessary complexity. No mixing business with personal life.
