Glasp's Core Features in Detail

Powerful features from Glasp

Knowledge Accumulation

Highlights that disappear into individual apps produce knowledge that is hard to retrieve later. A searchable library that accumulates over time makes past learning accessible

Social Reading Value

Seeing what thoughtful readers have highlighted from the same source surfaces insights that individual reading might miss

Export Flexibility

Highlights that can flow into personal knowledge management systems like Notion and Obsidian integrate with existing workflows rather than creating a new silo

Reading as Contribution

Making highlights public turns individual reading into a contribution to collective understanding that benefits other readers of the same content
