Structured, searchable
storage for everything you know
ESB files knowledge on four levels — a Class holds Categories, a category holds Topics, and a topic holds the Information records themselves. Nothing floats loose; everything has an address.

How it is organised
Four levels, always in the same order. Follow them down and you land on a record; read them back up and you know exactly where it came from.
- Languages
- English
- Grammar
- records
Class
e.g. “Languages”
The broadest shelf in the bank. A whole field of knowledge — Languages, Computer Science, History.
Category
e.g. “English”
A subject inside that class. Also called the subject: English, Arabic, Programming, Networks.
Topic
e.g. “Grammar”
One theme inside the subject. Grammar, Vocabulary, Algorithms, Databases — the shelf you actually reach for.
Information
e.g. “Irregular past-tense verbs”
The record itself: a title, a body, tags and a source. This is the thing you came to read.
Start with a class
Each class is a field of knowledge. Open one to see its categories, its topics and the records inside them.
