Zettelkasten
A Zettelkasten is a note-taking system that builds a network of small, linked, atomic notes to help you develop and reconnect ideas over time. Originating with sociologist Niklas Luhmann, it’s designed to turn scattered thoughts into a growing, searchable web of knowledge.
Zettel
A zettel is a single, self-contained note that captures one idea, fact or insight. Used in the Zettelkasten (slip-box) method, zettels are linked together to form a searchable, networked knowledge system.
Evergreen Notes
Evergreen notes are permanent, reusable notes that capture distilled ideas, insights or explanations so they can be easily found and combined over time. Unlike fleeting reminders, they’re written to be understandable and useful months or years later.
Atomic Notes
Atomic notes are very small, single-idea notes that store one concept per card or entry to make ideas easier to find, link and recombine. They are the building blocks of personal knowledge systems like Zettelkasten.
Fleeting Notes
Fleeting notes are quick, informal captures of thoughts, reminders or observations meant to be recorded instantly and processed later. They prioritise speed over structure so ideas don’t get lost in the rush of a busy day.
Literature Notes
Literature notes are concise, source-linked summaries you write while reading a book, paper or article that capture the author’s main points, key evidence, and any useful quotes or page references in your own words. They act as the bridge between raw highlights and long-term, reusable ideas.
Permanent Notes
Permanent notes are concise, durable pieces of knowledge written in your own words and stored for long-term use and connection with other notes. They capture ideas, insights, or facts in a way that makes them easy to find, reuse and build upon over time.
Slip-box
A slip-box is a personal knowledge system built from individual note 'slips' (cards) that are uniquely identified and interconnected to grow understanding over time. It turns isolated facts and fleeting ideas into a networked archive you can query, develop, and reuse.
Unique Note Identifier
A Unique Note Identifier is a distinct code assigned to each note or captured item so it can be reliably found, linked and synced across systems. It ensures every voice capture, task, or snippet can be referenced without confusion.
Zettel ID
A Zettel ID is a unique identifier assigned to a single note (a “zettel”) in a Zettelkasten-style system so each idea can be referenced and linked reliably. It acts like a permanent address for that note within a personal knowledge network.
Map of Content (MOC)
A Map of Content (MOC) is a central hub or index that organizes and links related notes, topics or projects so you can find and navigate your personal knowledge quickly. It’s a lightweight overview that connects ideas instead of burying them in folders.
Index Note
An index note is a central, organized note that links to and summarizes related notes, tasks, or resources—acting like a table of contents or map for a topic. It helps you find, navigate, and maintain an overview of a subject in your personal knowledge system.
Note Granularity
Note granularity describes how detailed or large a single note or task is — from atomic, one-action items to broad, multi-step summaries. It determines how easy a note is to act on, search, and organize.
Note Atomicity
Note atomicity is the practice of breaking information into the smallest self-contained notes—each representing a single idea, fact, or action. It makes notes easier to find, link, and turn into tasks.
Note Linking
Note linking is the practice of connecting individual notes or ideas with explicit relationships, creating a web of related thoughts instead of isolated files. It makes knowledge easier to navigate, grow and rethink over time.
Bi-directional Links
Bi-directional links are two-way connections between notes that show relationships in both directions, turning isolated pages into a navigable knowledge network. They let you jump from an idea to its references and back again, making context and connections visible.
Backlinks
Backlinks are bidirectional links that show every note or item that references a particular page or idea, creating a network of connected thoughts rather than isolated files.
Networked Thought
Networked thought is a way of organising ideas as interconnected nodes rather than rigid folders, letting relationships emerge and evolve over time. It treats notes, observations and tasks as links in a web that you can traverse and expand.
Note Graph
A note graph is a networked map of individual notes or ideas (nodes) connected by explicit links (edges), creating a web of relationships that surfaces context and meaning across your personal knowledge. Unlike folders, it emphasizes connections and discovery over rigid organization.
Knowledge Graph
A knowledge graph is a web-like map of related ideas, facts and items where each piece of information (a node) is connected to others by meaningful relationships (edges). It stores context as relationships, not just isolated files, enabling discovery and smarter matches between things you know.
Concept Map
A concept map is a visual diagram that shows ideas (nodes) and the labeled relationships between them, helping you see how concepts connect. It’s used for brainstorming, learning, planning and clarifying complex topics.
Mind Map
A mind map is a visual diagram that starts from a central idea and radiates outward into connected branches representing related concepts, tasks or details. It helps people organise thoughts, spot relationships and spark new ideas quickly.
Transclusion
Transclusion is embedding a piece of content by reference so the same source appears in multiple places and updates everywhere when the original changes. It creates reusable, single-source blocks of information across notes and documents.
Progressive Summarization
Progressive summarization is a layered note-distillation method that helps you capture information once and make the most important parts easy to find later. It gradually reduces noise by highlighting and re-summarising notes into shorter, more useful summaries.
Synthesis Note
A Synthesis Note is a concise, integrated record that combines key points, insights and actions from multiple sources or experiences into a single, connected entry. It focuses on meaning and relationships rather than verbatim transcriptions.
Synthesis Writing
Synthesis writing is the practice of combining multiple pieces of information—notes, observations, research, and ideas—into a single coherent piece that highlights connections and produces new insight or action. It’s more than summarising facts; it reorganises and reframes them to support decisions, plans, or arguments.
Progressive Refinement
Progressive refinement is the iterative process of turning rough ideas or captures into clear, actionable tasks or knowledge by gradually adding detail, context and priority. It moves items from fuzzy notes to concrete next steps without demanding perfection up front.
Note Refactoring
Note refactoring is the practice of revisiting and reorganising existing notes to make them clearer, more actionable, and easier to find. It treats notes like evolving ideas—cleaning, condensing, linking and extracting tasks so information becomes usable rather than just stored.
Note Provenance
Note provenance is the set of information that describes where a note came from and how it was created—its origin, time, author, and context. It helps you judge a note’s reliability and quickly reconnect ideas to the moment they were captured.
Note Versioning
Note versioning is a feature that saves and organizes a chronological history of edits to a note so you can view, compare, and restore earlier versions. It acts like an automatic “undo/history” for your ideas and documents.
Note Metadata
Note metadata is the descriptive information attached to a note that explains its context — things like date, tags, project, priority and source. It turns a passive scrap of text into something searchable, actionable and automatable.
Tagging Taxonomy
A tagging taxonomy is an intentional, shared set of tags and naming rules used to label, group and find items in a personal or team system. It defines tag types (e.g., project, context, priority), naming conventions, and how tags should be applied.
Folksonomy
Folksonomy is a user-driven system of organizing information with free-form tags rather than a fixed hierarchical taxonomy. It reflects how real people label ideas and items in their own words.
Personal Ontology
A personal ontology is an organized map of the categories, labels and relationships you use to describe your tasks, notes and commitments. It’s a lightweight, personalised system (folders, tags, contexts, priorities and rules) that gives your scattered thoughts consistent meaning.
PARA Method
PARA is a simple system for organising information and work into four universal buckets—Projects, Areas, Resources, and Archives—so you can find what matters and act on it quickly. It’s device- and tool-agnostic, designed to reduce clutter and support focused work.
Second Brain
A second brain is an external system—digital, analog, or hybrid—that you consistently use to capture, organise and retrieve ideas, tasks and knowledge so your mind can focus on thinking rather than remembering. It turns scattered thoughts into searchable, actionable items you can rely on later.
Note Capture
Note capture is the quick, low-friction recording of ideas, tasks or observations the moment they occur so they can be processed later. It’s the first step in a productive personal knowledge workflow—catching things before they’re forgotten.
Note Templates
Note templates are pre‑built outlines or forms that structure how you capture information so entries are consistent and faster to create. They provide placeholders, headings and optional metadata to guide what to record.
Retrieval Practice
Retrieval practice is the learning technique of actively recalling information from memory (self-testing) rather than passively reviewing it. Repeated, spaced retrieval strengthens long-term recall and makes knowledge easier to access under pressure.
Spaced Repetition
Spaced repetition is a learning technique that schedules review of information at increasing intervals to strengthen long-term memory. It leverages the brain's forgetting curve so you review just before you would forget.
Active Recall
Active recall is a study and memory technique that strengthens retention by forcing you to retrieve information from memory instead of passively reviewing it. Regular, effortful retrieval builds deeper, more durable knowledge and skill.
Feynman Technique
A simple learning method popularised by physicist Richard Feynman that deepens understanding by forcing you to explain a concept in plain language and then iteratively fix gaps. It turns passive reading into active, testable knowledge.
Annotation
Annotation is the act of adding notes, highlights, tags or comments directly to a piece of content to capture meaning, questions, or actions tied to that source. It connects ideas to their original context so they’re easier to remember, search and act on.
Marginalia
Marginalia are the notes, comments and little marks people write in the margins of a text to react to, summarise or extend what they’re reading. They turn passive reading into an active, conversational process with the material.
Excerpting
Excerpting is the practice of selecting and saving short, meaningful passages from a longer text or note so you can quickly access, reuse, and connect the most important ideas. It captures the essence of a source without copying everything verbatim.
Hypothesis Note
A hypothesis note is a short, testable idea recorded as a note so you can try it, measure the outcome, and learn from the result. It pairs an assumption with a simple experiment and a clear success criterion.
Literature Synthesis
Literature synthesis is the process of combining insights from multiple sources to produce a coherent, higher-level understanding or argument. It moves beyond summarizing individual texts to identify patterns, contrasts, gaps and implications across a body of work.
Emergent Knowledge
Emergent knowledge is the new understanding, patterns or insights that naturally arise when small, scattered pieces of information are collected and later connected over time.
Knowledge Modeling
Knowledge modeling is the practice of representing information, concepts and their relationships in a structured way so they can be found, reused and reasoned about. It turns scattered notes and ideas into organized maps that support search, automation and better decisions.
