Web scraping is the automated extraction of data from websites using software — sending HTTP requests, parsing HTML, and extracting specific elements (prices, text, images, links) at scale or speed impossible by manual copy-paste. It's used for research, monitoring, data pipelines, and AI training data.
Intermediate packets are small, discrete, reusable units of work — an outline, a research summary, a slide deck draft, a set of notes — that can be saved and reused across future projects rather than starting from scratch each time.
A bullet journal (BuJo) is an analog organization system created by Ryder Carroll using a dot-grid notebook: rapid logging with bullet symbols, collections (logs, trackers, lists), and migration (intentional task review). It combines daily planner, to-do list, diary, and habit tracker in one notebook.
A KWL chart is a three-column learning organizer: K (What I Know), W (What I Want to Know), L (What I Learned). It activates prior knowledge before learning, sets specific goals, and documents what you actually learned — making the learning process active and self-directed.
A literature note is a processed reading note — what you learned from a source, written entirely in your own words, kept with the source reference, serving as the bridge between reading and the permanent ideas in your knowledge system.
A memory palace (also called the method of loci) is an ancient memory technique where you mentally place information at specific locations along a familiar route or inside a known building, then 'walk' the route to retrieve it in order.
A permanent note is the final-stage note in the Zettelkasten system — a single idea, written in your own words, intended to last indefinitely, explicitly linked to related notes. It's the unit of knowledge in your slip-box.
A structure note (also called a map of content or index note) is a note that organizes other notes — a high-level overview that links to related permanent notes, providing navigation and context to a cluster of ideas in your knowledge system.
Concept mapping is a structured visual diagram where concepts are represented as labeled nodes connected by labeled relationship lines — making the relationships between ideas explicit, not just the ideas themselves. It was developed by Joseph Novak at Cornell in 1972.
Just-in-time note-taking means capturing, processing, and retrieving notes at the moment you actually need them — rather than comprehensively documenting everything upfront. It's the practice of matching your note-taking effort to the actual demand for the information.
Mind mapping is a visual note-taking technique where ideas radiate from a central concept in branches, capturing associations non-linearly. Popularized by Tony Buzan in the 1970s, mind maps externalize the brain's associative thinking, making brainstorming, planning, and review faster.
Progressive summarization is a note-processing technique by Tiago Forte: save content, then add layers of highlighting in passes — bolding the most important passages, then highlighting the most important bolded text — making notes more retrievable over time without upfront work.
Retrieval-Augmented Generation (RAG) is an AI architecture that supplements a language model's response with real-time retrieved documents from a knowledge base — combining the LLM's language ability with accurate, up-to-date, source-traceable information from your own data.
Sketchnoting is a visual note-taking method that combines hand-drawn text, simple illustrations, icons, and layouts to capture ideas — replacing the pure-text linear note with a richer visual record that's faster to create than it looks and significantly more memorable.
SQ3R is a structured reading method with five stages: Survey (preview), Question (generate questions), Read (actively), Recite (recall without looking), Review (revisit key points). It turns passive reading into active learning, significantly improving comprehension and retention.
The CODE method is a personal knowledge management framework by Tiago Forte with four stages: Capture (save what resonates), Organize (sort for action), Distill (extract the essence), Express (create with what you've saved). It's the workflow behind Building a Second Brain.
Time blocking is a scheduling method where you divide your workday into dedicated blocks, each assigned to a specific task or type of work — rather than working from a to-do list reactively. Cal Newport and Elon Musk use it; research on focused work validates it.
A citation index is a database that tracks which papers cite which other papers, letting researchers trace influence, find seminal works, discover recent work building on a key study, and assess the impact of research across time.
A commonplace book is a personal collection of quotes, ideas, passages, and observations gathered from reading and experience — organized for retrieval and creative use. It's the original external memory and idea repository, practiced by writers for centuries.
A fleeting note is a quick, temporary capture of an idea, thought, or observation as it occurs — raw and unprocessed. It's the first stage of the Zettelkasten workflow: capture everything potentially valuable before the moment passes, then process later.
A literature review is a systematic survey of published research on a topic — identifying what is known, what is contested, what gaps exist, and how your work contributes to the conversation. It's the foundation that connects new research to existing knowledge.
A personal CRM is a self-managed system for tracking relationships, conversations, and context about people you know professionally — giving you the information you need to maintain genuine relationships at scale without relying on memory alone.
A slip-box (Zettelkasten) is a personal knowledge system of atomic, linked notes on individual cards or files — each containing one idea, linked to related ideas, forming a network that generates emergent connections and insights.
A systematic review is a rigorous, reproducible synthesis of all available research on a specific question — using pre-specified methods to identify, select, and critically appraise studies, minimizing bias in how the evidence is assembled.
