About Endoxa

How Endoxa helps you study

Endoxa enables you to see an argument visually and learn how to better use arguments in your studies.


  • Mapped to A Level curriculum and exam boards.
  • Includes interactive study materials to help you learn.


Endoxa is a new and innovative way to learn, practise and apply your knowledge. The Endoxa platform is designed to take reasoning and argumentation away from long dense texts and make it more engaging through interactive ‘argument graphs’.

Device Frame

The result is learning and using arguments is faster, easier and more interesting.



The Endoxa argumentation graphs are based on A Level subjects and lessons so you can easily navigate to the topics you need. Each interactive Endoxa lesson contains the key facts and arguments you need to learn for a given topic.



You can test your learning with interactive tasks, including connecting parts of arguments and understanding how they relate. At the end of each lesson, you can modify the argument graph to represent your response to the argument – add a counter-argument, change a premise from true to false, and so on. Your finished argument graph then serves as a visual essay plan or a summary for revision.

How Endoxa works

Endoxa is a completely new way to study. At its core is a powerful engine that analyses arguments and displays them visually: the argument graph


  • Argument are analysed into steps – each step classified by its “argument type”
  • Key parts of the argument made immediately clear by the graphical display: premises, conclusion, counter-arguments, etc.
  • Argument type definitions such as: cause and effect, implication, entailment and analogy
  • Factual information usch as examples and case studies embedded into the diagrams
  • Calculation of the strength and coherence of an argument

Our Story

Inspired by the quest for truth: the Endoxa story

Critical thinking and argumentation skills are increasingly important for students. That’s why we have specifically designed Endoxa with A Level students in mind to help visualise the key arguments in a topic to apply in essays, assignments and exams.

We consulted research and studies going back over 50 years about how to visually represent arguments in diagrams. We developed Endoxa to visually express, classify and evaluate arguments in a simple and practical way so everyone can reason well with our responsive and intuitive system.

We have updated and refreshed the way you learn by stripping away the long, dense texts to replace them with visual, interactive software.


Benefits of using Endoxa:

  • Faster learning
  • Simplified arguments
  • Readily create your own arguments
  • Be confident that you understand the key points and are using them correctly
  • Enhance your critical thinking skills

For Academics

The ‘argument first’ model which Endoxa follows has far-reaching and multi-disciplinary potential for overhauling the current framework of learning arguments and reasoning as well as enhancing critical thinking skills for everyone. Furthermore, Endoxa can be used for collaborative reasoning whereby the truth of an argument can be found in an interdisciplinary approach.
