Hands-on review

Semantic stock‑discovery and research site focused on the U.S. equity universe. The homepage invites natural‑language queries (e.g., describe the kind of companies you want) and searches a database of company analysis. Coverage claims ‘5,000+ US stocks,’ including microcaps, nanocaps, and OTC tickers. A free, optional email rounds up three ‘under‑the‑radar’ themes each Monday with catalysts, data, and stocks. Terms emphasize that content is for information/education only (not investment advice) and designate Washington State law/jurisdiction.
