> Open-source AI investment research software combining A-share, Hong Kong and US markets, fund research, an AI research agent and encrypted local notes.

Cloud Strategy Research is open-source AI investment research software for individual investors. The website reflects desktop software v1.0.0 and connects stock and fund research, multi-turn AI conversations, notes, holdings and watchlists. Features include QDII, ETF and LOF categories, disclosed NAV details, AI material previews, quote monitoring and encrypted local data import and export.

## Factual boundaries
- The website provides no trade execution, investment advice or return promises.
- Market and AI demos use synthetic data and preset content.
- Market data uses built-in Local mode, prioritizing Eastmoney; coverage and timing depend on upstream interfaces. Open-ended fund NAV and exchange prices are distinct.
- An installer is public only when the download center lists a real version and URL.
- Product capability information was updated on 2026-09-19.
