Connect related ideas
Link notes and follow the backlinks
Folders tell you where a note belongs. Links show how its ideas relate to the rest of what you know. Connect a concept to another lecture, reading, or course and use backlinks to find the relationship from either side.
Build a study library that becomes more useful every time you add a note.

What it gives you
A study library that keeps its structure.
See what links back
Backlinks reveal which other notes point to the one you are reading, so useful context is not lost.
Cross folder boundaries
Connect ideas even when the notes live in different course, module, or topic folders.
How it works
Useful when the library gets bigger.
- Links complement folders rather than replacing them.
- Backlinks help resurface older notes when a new topic relates to them.
- Related notes can also be selected and read together for broader revision.

- 2

Choose another note that adds context, evidence, or a useful contrast.

Questions
Know exactly what the feature does.
What is a backlink in BrainDen?
A backlink shows that another note links to the note you are viewing. It lets you follow the connection in the opposite direction.
Can linked notes be in different folders?
Yes. Linking works across the library, so related ideas do not need to share the same folder.
Does linking combine or overwrite my notes?
No. Each note stays intact. A link records the relationship without changing either note's content.
