About this app

Build a knowledge tree that organizes itself.

Linko helps you turn what you read and think into a growing knowledge system — so your ideas don’t get lost in scattered notes.

Perfect for: learners, readers, students, researchers, and creators

Capture your thinking
• Jot ideas, questions, and reflections on mobile or web
• Save books, articles, videos, and podcasts alongside your own thoughts

Auto-organize (no folders)
• AI tags your notes so related ideas naturally group together
• Focus on thinking, not filing

Discover connections automatically
• Related notes resurface when you need them
• Connect insights across time and sources

Review and learn faster
• Knowledge tree visualization shows what you’ve learned — and what’s missing
• AI summaries and Q&A based on your saved content

Available on mobile + web (with browser extension).
