Triall
Reduce AI hallucination: Triall routes your question through multiple frontier AI models (Claude, GPT, Gemini, Grok + 120 more) that answer independently, anonymously peer-review each other, debate, fact-check claims against the live web, and survive a devil's advocate — returning one verified answer with full transparency into where the models disagreed. Free tier, no signup.
Overview
Triall — AI answers that survive cross-examination
Single AI models hallucinate independently — confident, fluent, and sometimes completely wrong. Triall routes your question through multiple frontier models (Claude, GPT, Gemini, Grok + 120 more) that answer independently, anonymously peer-review each other, debate, fact-check claims against the live web, and face a devil's advocate — returning one verified answer with full transparency into where the models disagreed.
Triall is an end-user answer engine, not a developer eval platform. You don't instrument anything — you ask a question and get a cross-examined answer.

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
