Librum
Learning reinvented
Librum evolved from turning pages to building knowledge.
The goal
To find intuitive solutions that let users have both notes and resources (books, documents, etc.) in Librum while also making it possible to organize their library well.
The approach
We explored two main directions:

GoodNotes-style approach
Notes and resources live together in the same system.Users can group them into folders or collections.Pros: Feels flexible and simple; mirrors how people organize physical notebooks.Cons: Large collections risk becoming cluttered.

Separated Views approach
Notes and resources are in distinct spaces, each with its own folder structure.Pros: Clear separation; easy to navigate depending on intent (reading vs. note-taking).Cons: Risk of context-switching and fragmentation.
Prototyping
Built low-fidelity prototypes of both approaches.
Conducted usability sessions with students and professionals

Key insights:Users wanted a sense of connection between notes and the resources they came from.
Library organization was critical — users needed both quick access and hierarchical control.
Flexibility was more important than rigid structures.
Final direction
We designed a hybrid model:
Resources (books, PDFs, documents) live in the main Library.
Notes can be:Attached directly to resources (anchored to pages/sections).
Created as standalone documents but still organized into the same folder system.
The folder system allows mixing resources and notes, but with filters and views for those who prefer separation.
