AI Verdict
Run ChatGPT, Claude, Gemini and Perplexity Side-by-Side
Last verified:
What is AI Verdict?
AI Verdict is a professional browser extension dashboard that allows you to query the world's leading AI models—ChatGPT, Claude, Gemini, and Perplexity—simultaneously with a single prompt. Instead of jumping between tabs, you watch all responses stream in live, side-by-side, in a unified interface. The extension's core feature, The Verdict Engine, analyzes all four responses to identify common ground, highlight contradictions (potential hallucinations), and synthesize a final consensus.
The tool features real-time streaming where you watch active models generate responses live side-by-side as they stream in, with no waiting for one to finish before seeing the next. Users can choose between Dashboard layout (grid view for scanning all models at once) or River layout (stacked view for focused, deep reading top-to-bottom). The interface includes light mode toggle, multi-turn conversation support with automatic context maintenance, and customizable settings for model selection, Verdict Lead, and synthesis prompts.
AI Verdict is built for people who take their AI research seriously—including researchers, professionals in finance/health/coding, and anyone making important decisions who needs to stop guessing which AI answer to trust. It eliminates tab-switching, requires no API keys (uses existing browser sessions), and ensures zero extra billing from AI providers since it leverages your existing accounts.

Frequently asked questions about AI Verdict
What is AI Verdict?
AI Verdict is a professional browser extension dashboard that lets you query ChatGPT, Claude, Gemini, and Perplexity simultaneously with one prompt. Responses stream in live side-by-side, and The Verdict Engine synthesizes them into a single consensus that highlights common ground, contradictions, and the most reliable answer.
How does The Verdict Engine work?
The Verdict Engine sends all four responses to a lead AI you choose (Claude, GPT-4, or Gemini) and synthesizes a single reasoned conclusion. It flags when one AI says something others don't, surfaces agreement and disagreement, and delivers the most reliable answer. You can override the prompt for pros/cons, recommendations, tables, or any format.
What's included in the free tier vs Pro?
Free tier includes ChatGPT and Gemini access only, without The Verdict Engine. Pro tier includes all four models (ChatGPT, Claude, Gemini, Perplexity) plus The Verdict Engine for consensus synthesis, custom verdict prompts, and the ability to choose your Verdict Lead model.
Do I need API keys for AI Verdict?
No API keys are ever needed. AI Verdict uses your existing browser sessions. If you already use these AIs in your browser, you're already set up. This also means there's zero extra billing from AI providers.
Which models work with zero setup?
ChatGPT, Gemini, and Perplexity work right away with no login needed. To use Claude or save your history, you just need to sign into those accounts in your browser.
What layouts are available in AI Verdict?
Two layouts are available: Dashboard layout (grid view for scanning all models at once side-by-side) and River layout (stacked view for focused, deep reading top-to-bottom). You can switch between them based on your comparison needs.
Can I customize the verdict prompt?
Yes, Pro users can write custom verdict instructions. You can ask for a structured comparison, a pros and cons list, a recommendation, a table, a devil's advocate view, or any format you need per query.
How do I choose my Verdict Lead?
Pro users can pick which AI generates the verdict—Claude, GPT-4, or Gemini. You choose the model you trust most to deliver the final synthesis. The lead model and prompt are fully customizable per query.
Does AI Verdict support follow-up questions?
Yes, AI Verdict supports multi-turn conversations. You can follow up with your active models in the same conversation thread, and context is maintained across turns automatically.
What use cases is AI Verdict best for?
AI Verdict works for research, health, finance, coding, and any decision where knowing which answer to trust is critical. It's built for people who take their AI research seriously and need to stop guessing between different AI responses.
