Disclosure: we make Thastock, so we list it first. Every other entry is described from the company's own pricing and feature pages, with sources on each comparison page.
Computes RSI, moving averages, earnings beat rate and insider activity first, then writes a bull case and a bear case that cite those numbers. Free plan; Pro is $9/mo.
