Hands-on review
Global stock and ETF research platform with screeners, valuation tools, customizable charts, and portfolio tracking. The free plan comes with meaningful but tight limits—such as two manual portfolios, one 10-ticker watchlist, and capped screener results—while paid tiers unlock the full feature set. Billing is monthly or yearly, with a 30-day money-back guarantee.

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 Pricing, features, and availability may be incomplete or out of date.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.
