Debate Evaluator
Stop Trusting Biased LLMs. Deconstruct the Debate.
Evaluate Every Claim.
Built for rigorous debate analysis
From raw video to structured, independently-scored argument trees - in minutes. Every layer of the stack is designed to eliminate bias and surface truth.
Any Starting Point
Start from a YouTube URL, an uploaded audio/video file, or a blank tree you build from scratch. No source required - just a position to argue.
Visual Argument Trees
Arguments become navigable logic trees. Drill into sub-claims, add hypothetical branches, and switch between an infinite canvas view or a structured threaded layout.
Multi-Model Consensus
A diverse panel of frontier LLMs - Gemini, GPT, Claude, Grok, and more - independently scores each argument. Model disagreement surfaces bias and uncertainty automatically.
Formal Logic Analysis
Every argument is structurally decomposed using the Toulmin model - claim, ground, warrant, backing, qualifier, and rebuttal. Logical validity and warrant strength made explicit.
Prolog Structural Analysis
Deterministic, rule-based analysis - not AI. Classifies argument schemes using Walton's taxonomy and detects cross-tree structural issues like pile-ons and unaddressed rebuttals.
Rich Auto-Tagging
Every node is automatically labeled with topics, fallacies, sources, keywords, argument schemes, and structural issues - enabling filtering, search, and pattern detection across the tree.
Hypothetical Simulations
Branch off the original debate at any node. Simulate a stronger counterargument, steelman the opposition, or explore a completely different line of reasoning.
Custom Criteria & Models
Bring your own API keys and configure which models evaluate each tree. Define custom scoring criteria per debate - no one-size-fits-all grading.
From position to verdict - any way you work
A flexible workflow that meets you where you are - whether you're analyzing an existing debate, preparing arguments for one you're about to have, or stress-testing a position you already hold.
Start
Paste a YouTube URL, upload an audio/video file, or start a blank tree from scratch around any position you want to explore.
Transcribe
Speaker-aware transcription automatically identifies and separates each debater. Skip if building from scratch.
Map
AI structures claims, sub-claims, and rebuttals into a visual argument tree. Manually add or edit any node.
Expand
Use AI to generate supporting or opposing arguments from any angle. Write a custom direction prompt to argue from a specific perspective. Accept, edit, or discard each draft.
Evaluate
A panel of frontier LLMs independently scores every node on logic, evidence, and rhetoric.
Analyze
Explore consensus, surface bias, run Prolog structural analysis, and identify fallacies and argument schemes.
