Strengthen Your Essays. Master the Art of Argumentation

Symbai’s Student Revision tool helps you build persuasive arguments, structure clearer essays, and sharpen critical thinking through AI‑guided practice — like a gym for your mind.”

WATCH IT IN ACTION
Symbai is a Totally New Take On Revision

Most revision tools drill facts or tidy up your wording. Symbai shows you how to build a strong argument — the heart of any good essay.

Where other platforms focus on memorising quotes or polishing sentences, Symbai teaches you to organise your ideas and defend them. A clear argument is what impresses teachers in subjects like English, history or social studies — style and facts matter, but without a persuasive line of reasoning, even a well‑written essay falls flat.

What others are saying

“I believe Symbai has the potential through its unique multi-AI approach to become ubiquitous in the field of critical thinking in the way that Grammarly is associated with writing or Quizlet is with flash cards.”



Nick Hanne 
Education Partnerships Manager at the Free Speech Union NZ

“Symbai fills a major gap in education — it equips students to think logically, independently, and critically. Unlike other tools, it offers a neutral, AI-driven platform where students can genuinely practise debating and refine their thinking. It’s like having a 24/7 mentor that challenges without bias. A powerful solution for those seeking depth over group think in today’s education landscape.”

The Two Most Effective Ways to Improve Critical Thinking

Unified in Symbai

Debating

Hundreds of thousands of students across 60 countries choose to spend their free time in formal debating competitions because it improves their critical thinking skills. 

Formal debating improves:

  • Dynamic reasoning — adapting ideas under pressure

  • Strategic thought — anticipating and countering objections

  • Cognitive discipline — structuring arguments with clarity and purpose

Increases Critical Thinking By Up To 50%

Competitive debate produces greater critical thinking improvement than argumentation courses.

8.6% Critical Thinking Gains In Just 3 Weeks

Students who participated in debate competition showed statistically significant improvements in critical thinking scores after just three weeks.
An 8.6% improvement in critical thinking is the cognitive equivalent of dropping your resting heart rate from 70 to 64 BPM. That's not learning facts or techniques — that's developing lasting cognitive fitness.

Argument Mapping

Argument mapping has been around for hundreds of years, used by philosophers, scientists, and modern critical-thinking educators to make critical thinking clearer by drawing it out.
 And for good reason: when done well, argument mapping is one of the most effective ways to improve critical thinking and develop sharper logical reasoning.

Argument mapping helps you:

  • Clarify reasoning by revealing the actual structure of your thinking
  • Expose weak links that get lost in normal prose
  • Build precision through visual logic rather than persuasive writing tricks

Improves Critical Thinking Courses By Over 300%

Critical thinking courses that used argument mapping software saw students improve their critical thinking over 300% more than similar critical thinking courses.
Compared a standard logic class to one using argument mapping software. The mapping group made dramatically greater gains on a standardized critical thinking test, far exceeding typical semester improvements.

One Semester Of Argument Mapping Produces 6-7x MORE Critical Thinking Gains Than One Semester Of Normal University Study

9% Critical Thinking Gains In Just Weeks

Five weeks of an argument mapping-led course resulted in an average critical thinking gain of 9%
These gains were achieved with minimal explicit critical thinking teaching. The gains came from interactions with other students within argument mapping software.

  • Strategic thought — anticipating and countering objections

  • Cognitive discipline — structuring arguments with clarity and purpose

If debating is the clash of ideas, argument mapping is the architecture that makes clear thinking possible.
 It’s the practice of breaking critical thinking into smaller parts — claims, evidence, objections, and assumptions — and arranging them so the logic becomes visible.

Argument mapping has been around for hundreds of years, used by philosophers, scientists, and modern critical-thinking educators to make critical thinking clearer by drawing it out.
 And for good reason: when done well, argument mapping is one of the most effective ways to improve critical thinking and develop sharper logical reasoning.

Argument mapping helps you:

  • Clarify reasoning by revealing the actual structure of your thinking

     

  • Expose weak links that get lost in normal prose

     

  • Build precision through visual logic rather than persuasive writing tricks

     

These benefits make it a powerful method for anyone looking to enhance critical thinking skills, improve decision-making, or analyze arguments more effectively.

But traditional argument mapping has limits:

  • Pen and paper mapping is slow and quickly becomes cluttered
  • Digital mapping tools speed things up but remain static
  • And because the map never talks back, even skilled thinkers can hit writer’s block when faced with a silent diagram
