Fintel brings short interest, off-exchange volume, institutional ownership, insider trades, ETF exposure, options sentiment, filings, screens, alerts, APIs, and AI research into ticker pages. It is useful for studying positioning and crowding before deeper fundamental work.

FlowAlgo monitors unusual options activity, sweeps, blocks, equity blocks, dark-pool prints, alerts, and historical flow. It provides order-flow context, not brokerage, fundamentals, backtesting, or portfolio accounting. There is no free tier, the introductory offer is paid, and flow does not prove intent or profitability.

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 Pricing, features, and availability may be incomplete or out of date.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