AI Verdict

AI Verdict is a browser extension for Chrome, Firefox, and Edge that accepts a single prompt and dispatches it simultaneously to ChatGPT, Claude, Gemini, and Perplexity. Responses stream in parallel across a dashboard layout — two panels side by side for direct comparison, or a stacked river view for sequential reading. Multi-turn follow-up is supported, with context maintained across turns. The vendor states no API keys are required; the extension authenticates through your existing browser sessions, meaning zero additional per-query billing from AI providers.

The differentiating feature is The Verdict Engine, a paid-only synthesis layer. After all models respond, you designate a lead model — Claude, GPT-4, or Gemini — and that model receives the full set of responses as input. It returns a structured synthesis: key mentions, common ground, flagged disagreements, and a final verdict. The synthesis prompt is customizable per query, so you can ask for a pros-and-cons table, a structured recommendation, or a devil’s advocate reading rather than a generic summary.

The tool fits a specific, narrow use case: a researcher, analyst, or informed individual who wants to pressure-test a question across multiple models without maintaining separate sessions. It works well for health, finance, career, and factual research queries where model disagreement is informative. It does not fit teams building pipelines, automating decisions, or integrating AI output into other systems — there is no API surface, no webhook, no programmatic access to results. The extension is the entire product, and the output lives in the browser.
