Unusual Whales is an options-flow and market-activity platform for traders who want real-time U.S. options trades, dark pool/off-exchange activity, alerts, screeners, news, congressional trading data, and developer API access. It is strongest for alert-driven options and order-flow research, with portfolio tracking, API, WebSocket streaming, and historical full-market options data handled through separate paid surfaces.

Fintel is a market-signal research platform for investors who want short interest, off-exchange volume, institutional ownership, insider trades, ETF exposure, options sentiment, filings, screeners, dashboards, alerts, APIs, and AI-assisted research in one place. It is strongest for ticker-level signal pages and ownership/short-interest workflows that help explain positioning, crowding, and unusual activity before deeper fundamental work. Many premium datasets, AI workflows, exports, options flow, and portfolio tools are tier-gated, and the signals should be treated as research inputs rather than investment recommendations.

Prospero.ai is a free mobile-first AI signal app for U.S. stocks and ETFs, with proprietary short-term and long-term signals, daily screens, stock picks, watchlists, notifications, and education. It is useful for beginner-friendly signal discovery, but it is not full fundamental research, broker sync, a web terminal, public API, or proof that a signal will work.

Quiver Quantitative is an alternative-data platform for investors who want dashboards, screeners, alerts, backtests, and API access around political trading, insider activity, institutional holdings, lobbying, government contracts, patents, app data, ETF exposure, dark-pool activity, and related datasets. It is strongest when conventional fundamentals are not enough and users want differentiated public-disclosure signals. Web Premium and Quiver API are separate products with different prices, trials, dataset tiers, and commercial-use rules. Alternative data can be noisy and lagged, so it needs validation before being treated as a signal.

Stocknear is a lightweight U.S.-market stock, ETF, and options research platform with options flow, dark-pool context, analyst data, 13F holdings, congressional trades, earnings, news, alerts, and an AI Agent. It is best for retail-friendly research dashboards and active monitoring, not global multi-asset coverage, brokerage execution, tax-lot accounting, or a self-serve data API.

Starred Tools
These are my top picks. Tools I've tested thoroughly and found to be excellent. They do their job really well, and I use them a lot. If you're not already familiar with them, I highly recommend checking them out.
Tested Tools
These are tools I've tried and found to be solid, but not standout. Think of them as passing an initial quality screen: worth exploring, though not all will be exceptional.
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.
