A

AI Agents AI systems that take a goal, plan a sequence of steps, and use tools to carry them out, rather than just answering a single question.

B

Browsing Context The collection of web pages, bookmarks, saves, and browsing signals that represent what you have found valuable online over time.

C

Context Switching The mental cost of shifting attention between different tools, tabs, platforms, or tasks while browsing, which fragments focus and slows knowledge work. Context Window The maximum amount of text an AI model can consider in a single request, measured in tokens, including both the input you send and the output it generates.

M

MCP Client An AI application that connects to MCP servers to access external tools, data sources, and prompts during conversations. MCP Server A program that exposes tools, resources, or prompts to AI assistants using the Model Context Protocol standard. Model Context Protocol (MCP) An open standard created by Anthropic that lets AI assistants connect to external tools and data sources through a single, unified interface.

P

Personal Knowledge Management (PKM) The practice of capturing, organising, and retrieving information you encounter so you can use it again later, usually through a system of notes, bookmarks, or links between ideas. Prompt Injection A security issue where untrusted content contains instructions that trick an AI model into ignoring its original task and following the attacker's commands instead.

R

Read-it-Later The practice of saving web articles, posts, and pages to a dedicated app or service to read at a more convenient time. Retrieval-Augmented Generation (RAG) A pattern where an AI model fetches relevant documents at query time and uses them as context, instead of relying only on what it learned during training.

S

Second Brain A personal knowledge management system that captures, organises, and resurfaces information you have collected over time, extending your biological memory. Semantic Bookmarking Saving and organising web content based on its meaning and topics rather than manual folder structures, typically using AI to understand and categorise content automatically.

T

Tab Hoarding The habit of keeping large numbers of browser tabs open as a way to remember or return to web content, often leading to browser slowdown and lost information. Topic Clustering An AI technique that automatically groups saved content into thematic clusters based on content similarity, replacing manual folder organisation.

V

Vector Embeddings Numerical representations of text, images, or other data that capture meaning, so similar content ends up with similar vectors and can be matched by concept rather than exact words.
