What problem does it solve?
Deep-search helps users answer questions that require up-to-date web evidence by searching across multiple engines, opening relevant pages, and collecting page snapshots and extracts to support cited responses.
Core Features & Use Cases
- Multi-engine deep web search: Runs targeted queries across many engines (Bing, Google, Baidu, Sogou/WeChat, 360, Toutiao, DuckDuckGo, Brave, Quark, and others) and switches when results are blocked or thin.
- Robust browser-backed evidence gathering: Opens promising result links, waits for content readiness, and collects browser_snapshot / browser_extract (plus screenshots when needed) for downstream answering.
- De-duplication and retry discipline: Avoids repeating the same searches/extractions too often, maintains an internal search ledger, and applies fallback strategies when pages are dynamic, blocked, or empty.
- Citation-ready output workflow: Supports numbered inline Markdown citations tied to inspected and extracted sources.
Quick Start
Ask to perform a deep multi-engine web research for your question and return a cited summary using evidence extracted from opened pages.
