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.

Curation & Accuracy
This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).
Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
