Query the world's leading AI models simultaneously. Get a single, synthesized response that combines the best of each. No more tab-switching. No more conflicting answers. Just clarity.
Watch how 5 AI models debate through 4 rounds to reach consensus
Each AI gives their first take
Models critique each other
Best arguments emerge
Claude synthesizes all perspectives into one coherent answer—combining the best insights from each model
You have access to more AI power than ever—Claude, GPT, Gemini, Grok, DeepSeek—yet making decisions has never been harder.
Claude excels at nuance. GPT at breadth. Gemini at current events. Grok at unfiltered takes. DeepSeek at technical depth.
Opening multiple tabs. Comparing contradictory answers. Wondering which AI to trust. Spending more time managing than thinking.
One AI giving you one answer with no peer review, no fact-checking, no challenge. AIs sound authoritative even when they're wrong.
There's a better way.
Legion sends your question to multiple AI models in parallel, then synthesizes their responses into a single, well-reasoned answer—complete with areas of agreement, disagreement, and nuance.
Type your question once. Legion handles the rest—no copy-pasting, no tab management.
Your query goes to Claude, GPT, Gemini, Grok, and DeepSeek—simultaneously.
View each model's individual response side-by-side. Complete transparency into their reasoning.
Legion identifies consensus, highlights disagreements, and delivers one coherent answer.
Unlike other AI tools, Legion makes models debate and refine their answers before you see them. This is structured deliberation, not simple comparison.
All 5 AIs answer your question independently, without seeing each other. Pure, unbiased first responses.
Each AI critiques the others. They identify mistakes, gaps, weak arguments, and unexamined assumptions.
AIs defend valid points and incorporate criticism into improved answers. Self-correction in action.
Final answer synthesizes consensus, key insights, and areas of disagreement into one coherent response.
The result isn't just "what Claude thinks" or "what GPT thinks" — it's the combined intelligence of five different AI architectures, stress-tested against each other.
Every feature designed to give you better answers, faster.
Why trust one AI when you can consult many? Legion's deliberation engine weighs multiple perspectives to surface the most reliable answer.
See exactly how each model responded. Drill into individual answers. Understand where they agree—and where they don't.
Choose which models to query. All of them. Just the top three. Or your custom combination. You're in control.
Legion remembers context across your session. Follow-up questions build on previous answers—no re-explaining required.
Download responses as markdown, PDF, or share a link. Perfect for research, documentation, or collaboration.
Use your own API keys for unlimited queries. Complete control over costs and usage.
Legion is overkill for "write me a poem." Use it when accuracy matters.
Contract review, compliance checks, case research. Mistakes are expensive.
"I used to spend hours cross-referencing AI responses. Legion gives me the synthesis in seconds—with citations to each model's reasoning." — Research Analyst
System architecture, security review, failure mode analysis.
"When evaluating architectural approaches, I want multiple expert opinions. Legion is like having a panel of senior engineers on call." — Engineering Lead
Diagnostic reasoning, drug interactions, clinical decision support.
Investment analysis, risk assessment, scenario planning.
"In M&A, missing a single risk factor can be catastrophic. Legion's multi-model approach catches things a single AI would miss." — Investment Professional
Market analysis, competitor research, product roadmaps.
"For content strategy, I need creative ideas AND practical constraints. Legion gives me both perspectives in one response." — Marketing Director
Literature review, methodology critique, hypothesis testing.
