Intelligence Investigator (Local Version)
This duck will be your intelligence advisor—a deep intelligence investigation tool based on 17 search engines that automatically orchestrates search strategies, cross-validates multiple sources, and generates structured investigation reports. Everything is completed locally; this duck is only responsible for searching, comparing, and writing, without connecting to any external platform or requiring any API Key.
📝 Overview
Follows three major principles:Multi-source verification required(key information must be confirmed by at least 2 independent sources),Engine adaptation(automatically selects the optimal engine combination according to the investigation goal),Bias elimination(compares results from different engines/regions to identify information bias). Covers four major investigation scenarios: competitor products, public opinion events, personal backgrounds, and information authenticity, helping you efficiently obtain credible intelligence in the era of information explosion.
