More About Connor

In Connors Words

“Symbai exists to make rigorous thinking accessible to anyone who wants to challenge their mind — not just those who already love to argue.

After six years of refining ideas from classrooms, coaching, and code, I built Symbai to make advanced argumentation easy to access — and even fun. It’s where technology meets the art of reasoning, helping you think more clearly, question more deeply, and engage with ideas that push you forward.”

Built for Every Level of Debate — From Grassroots to Elite Coaching

Symbai helps every program do more with the time and resources they have.

For under-resourced schools and clubs, it acts as a virtual debate partner—guiding students through structured cases, rebuttals, and feedback even without a full team or coach.

For elite academies and coaching services, it’s a force multiplier—automating fundamentals, mapping arguments, and running AI rebuttals so coaches can focus on the strategy and delivery that win tournaments.

Symbai bridges accessibility and excellence, giving every debater the chance to train like the best—and every coach the freedom to teach at their highest level.

Mooting Prep for your Debate Team

Symbai was created by debate coaches for debate coaches
to solve the pain points every coach experiences.

Case Construction

Case Construction → Enhanced with Symbai

Without Symbai

  • Students often draft cases in bullet-point form, which are usually shallow and repetitive.
  • Exemplars are rare; students don’t see what a “perfect” case looks like.
  • Student cases are often written over several pages, making it difficult to see the ‘big picture’ at a glance.

With Symbai

  • Cases can be built visually in minutes with editable AI-generated ‘debatetree’ exemplars that can be edited to the right level.
  • Symbai’s ‘debatetree’ visual format makes shallow arguments obvious and helps students expand ideas with a drag-and-drop toolkit.
  • Argument types and icons guide students to think strategically.
  • A ‘request rebuttal’ tool lets them stress-test cases with AI-generated rebuttals.
  • The AI tutor gives instant feedback on structure and content, or can be disabled for independent practice.
Result - Coaches save prep hours. Debaters instantly see how to strengthen their case.
Rebuttal & Clash

Rebuttal & Clash → Enhanced with Symbai

Without Symbai

  • Rebuttal practice is limited due to the constraints of in-person requirements.
  • Students default to shallow rebuttals (“That’s not true”) instead of thinking strategically.
  • Students struggle to see how individual rebuttals come to form broader points of clash.
  •  

With Symbai

  • Each student can practise rebuttals against the AI opponent at home.
  • Students have access to the ‘rebuttal toolkit,’ which provides inspiration and guidance for more strategic rebuttals than simply ‘that’s not true.’
  • The visual representation of rebuttal chains clarifies points of clash and encourages debaters to consider if they are driving the debate or merely reacting.
  • The debatetree structure allows students to quickly prepare rebuttals, allowing for more active listening during debates.
 
 
 
Result - Every debater gets more clash reps than in live-only training.
Delivery & Style

Delivery & Style → Enhanced with Symbai

Without Symbai

  • Students often read word-for-word from notes or essays, leading to poor eye contact.
  • Students get lost in their own notes, leading to panic at the lectern.
  • Students fail to signpost.

With Symbai

Students can use their debate mindmaps (called ‘debatetrees’) as a structured approach to debate notes.  The ‘debatetree’ structure:

  • Forces students to keep their notes brief
  • Utilizes visual icons and connectors to quickly remind debaters of vital information.
  • Encourages clear signposting as students move between argument branches.
Result - Students focus on implementing the feedback you provide regarding speech delivery rather than worrying about covering all the content in their notes.
Adjudication & Feedback

Adjudication & Feedback → Enhanced with Symbai

Without Symbai

  • Tracking points of clash and other structural aspects in document form is difficult.
  • Students struggle to retain the mostly auditory feedback given.
  • Weak adjudication = weaker learning loop.

With Symbai

  • Map student arguments quickly using Symbai’s drag-and-drop canvas to map arguments in real time, allowing you more time for active listening.
  • Coaches receive a performance dashboard that includes suggested points, rebuttals, and the time spent by each student in the debate.
  • Each adjudication yields a structured overview that can be shared with students.
Result - Every debate becomes a feedback loop — mapped, measured, and reviewable — so students can finally see why they won or lost, not just that they did.

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.
Allen et al. measured the improvement using the Watson–Glaser critical-thinking test — a gold-standard assessment of inference, deduction, and evaluation skills.”

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

Semester-long CT courses using digital argument mapping consistently produced effect sizes of 0.7-0.85 on standardized critical thinking tests. By comparison, a typical university semester yields just 0.11

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.

Debating develops the habits that critical thinking courses try to teach:

  • Dynamic reasoning — adapting ideas under pressure

  • 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
