Personal knowledge management tools typically focus on notes, but our knowledge actually lives across many different types of content: documents, images, videos, bookmarks, and and more.

In this session, Jan Lunge presents an approach to organizing all of these in one system through tags and mentions, forming a unified knowledge graph that connects notes and files together.

The talk will explore the ideas behind Heaper, a local-first and self-hostable knowledge system that got its first showcase on the PKM summit 2025 and evolved a lot since then through the great feedback and discussions here.

The session also invites discussion: What should the next generation of PKM systems look like? now that data ownership in an AI driven future becomes more important than ever.
