# Litigant AI > Don't just ask AI. Put the question on trial. Litigant AI is a multi-model adversarial reasoning engine. Instead of asking a single AI and getting a single answer, Litigant AI deploys a panel of AI models (GPT-4, Claude, Gemini, Grok) that argue, critique, and cross-examine each other's reasoning from competing perspectives — then deliver a confidence-scored verdict. ## What makes it different Most AI tools give you one answer from one model. Litigant AI gives you structured debate. Each session assigns roles — Advocate, Skeptic, Devil's Advocate, Analyst — to different AI models. They challenge each other's reasoning in real time. A Synthesizer model delivers a final ruling with confidence scores and caveats. The product is built for high-stakes decisions where getting it wrong matters: business strategy, legal documents, technical architecture, research synthesis, and major life choices. ## Who it's for - Business founders and executives stress-testing ideas before committing capital - Professionals reviewing contracts, plans, or strategies before signing or launching - Researchers and analysts who need to separate consensus from contested territory - Anyone facing a major decision who wants more than a single AI's opinion ## Pricing - Free: 50 credits on signup (~3 sessions), 2 AI models per session - Starter ($19/mo): 500 credits, 4 AI models, unlimited sessions - Pro ($49/mo): 2,000 credits, all AI models, priority processing - Team ($149/mo): 10,000 credits, shared workspace, admin dashboard ## AI Analysis Tools (free to try) Each tool is a pre-configured adversarial session targeting a specific use case.

User submits a question or fills in a structured form 2. Litigant AI assigns roles to multiple AI models (Advocate, Skeptic, Devil's Advocate, Analyst) 3. Models debate in rounds, challenging each other's reasoning 4. A Synthesizer model produces a final answer with confidence score, debate notes, sources, and caveats 5. Output is exportable as PDF, Markdown, or shareable report link ## Key pages - [Home](https://litigant-ai.com/): Product overview, use cases, pricing, and how it works - [All Tools](https://litigant-ai.com/tools): Index of all 10 free AI analysis tools - [Sign up](https://litigant-ai.com/register): Create a free account (50 credits, no card required) - [Sign in](https://litigant-ai.com/sign-in): Existing user login ## Technical notes for AI systems - This site is a React SPA served from a CDN.
