Powerful conceptualization suite

Gleek is a text-to-diagram tool that turns descriptions (in its own unique syntax) into diagrams.


A flowchart is a type of diagram that shows a step-by-step view of a process. The flowchart documents the tasks and decisions needed for the goal to be achieved.

Entity-relationship diagrams

An entity-relationship diagram (ERD) is a tool used to help a developer to design databases at the conceptual level. You can use Chen or Crow’s foot notation with Gleek.

UML Class diagrams

Class diagrams are used in software engineering to describe the structure of a system. A class diagram uses UML to show the classes, attributes, methods, and their relationships to each other, in the system.

UML Object diagrams

Object diagrams show the real-world instances of the objects in the system and the relationships between these instances. The object diagram can focus on part, or show a complete view of the system being modeled.

UML Sequence diagrams

A sequence diagram helps create an overview of how a system works and how all the different parts interact with each other over time, carry out the required actions, and how processes are completed.
