Key Concepts
Seven terms that appear throughout Relinkia. Understanding them will make the rest of the documentation — and the product — much clearer.
Note
The basic unit of thinking in Relinkia. A note is a moment of thought — not a finished document. Notes come in five types that reflect how mature an idea is: ephemeral (a quick capture), literature (from a source you've read), permanent (a consolidated idea), index (a map of a topic), and project (anchored to a specific goal).
An ephemeral note might be "interesting claim about memory from this podcast." A permanent note is the conclusion you drew from it three weeks later.
Space
A contextual filter for your notes. Spaces let you separate "work" from "personal" or "research project A" from "research project B" — without creating isolated silos. Your graph remains unified; spaces are just a lens.
You can have a "Pro" space and a "Learning" space. A note can belong to both. The AI can surface connections across spaces.
Concept
A recurring idea, theme, or entity that appears across your notes. Concepts are the vocabulary of your thinking. They can be detected by the AI from your writing (you validate or reject them) or added manually. They become nodes in your graph.
"Cognitive load", "anti-fragility", "client onboarding" — concepts are the recurring ideas that connect your notes across time and context.
Link
A connection between two notes or between a note and a concept. Links can be untyped (a simple reference via [[wikilink]]) or typed (a semantic relationship: "this note supports", "tensions with", "is an example of"). Typed links carry more information and are more useful for the AI.
Linking "Note A supports Note B" tells the system — and you — something different from "Note A contradicts Note B".
Session
A recorded thread of navigation through your notes. When you work, Relinkia captures which notes you visited and why you moved between them. Sessions let you resume a line of thinking exactly where you left off — days or weeks later.
You start from a note on "attention economics", follow a chain to three related notes, and end on a half-formed idea. The next morning, you open the session and pick up the thread.
Graph
The visual map of your knowledge. Nodes are your notes and concepts; edges are the links between them. The graph is not something you build manually — it emerges from how you write and connect. Clusters reveal domains of dense thinking. Isolated nodes reveal gaps.
A dense cluster of notes around "user research" with thin connections to "product decisions" might signal that you've been gathering without synthesising.
Temporality
The dimension of time in your knowledge. Notes mature. Links age. Ideas that were central six months ago may now be peripheral — or ready to be revisited. Relinkia tracks this evolution and surfaces dormant connections as signals, not problems.
A link you created eight months ago and never revisited isn't a failure — it's an invitation. The system will surface it at the right moment.
