Connect the dots of your digital life
Transform scattered notes, bookmarks, contacts, and media into a living knowledge network — then discover the people behind the information.
Three Dimensions of Connection
Info ↔ Info
Link your notes, bookmarks, contacts, and media into a connected knowledge graph. See how everything relates — and discover insights you never expected.
People ↔ People
Discover like-minded people through shared interests, overlapping knowledge, and complementary expertise. Build meaningful connections beyond simple friend lists.
Info ↔ People
Find who has the information you need. Instead of exposing sensitive data, Link123 reveals relationship paths — so you can connect safely, offline, through people you trust.
Built for Your Digital Life
Personal Knowledge Graph
12 types of entities, rich relationships, and cross-language search. Write in Chinese, search in English — your knowledge connects seamlessly across languages.
End-to-End Encrypted
Your sensitive data is encrypted on your device before it ever leaves. We cannot read it. No one can — not even us. Zero-knowledge architecture.
12 Content Types
Notes, voice memos, bookmarks, contacts, organizations, locations, tags, files, life events, structured data, media groups, and narrated subtitles — all in one place.
Smart Discovery
Our graph-powered recommendation engine surfaces connections you would never find manually — both in your content and across the community.
Secure Messaging
End-to-end encrypted conversations with rich content sharing. Forward any item from your personal space directly into a chat.
AI Personal Knowledge Assistant
Your AI remembers conversations, understands your data, and searches your personal knowledge graph across languages. Your data, your choice of AI model — always.
