Koyfin is a modern web and mobile financial terminal for investors, analysts, and advisors who want dashboards, charts, screeners, portfolios, news, alerts, transcripts, and market data without using a traditional desktop terminal. It is strongest for building custom research workspaces across equities, ETFs, funds, macro data, FX, commodities, crypto, yield curves, and advisor reporting. Free access is useful for trialing the workflow, while paid and Advisor tiers unlock more dashboards, screens, history, alerts, reporting, integrations, and client-portfolio features. It does not offer a public API.

CapEdge is a free SEC filings, transcripts, IPO, ownership, ETF exposure, and short-interest research platform from Finsight for US equity-capital-markets work. It is strongest for investors who want a registered, no-cost workflow around EDGAR search, filing diffs, filing alerts, XBRL financial charts, holdings, and IPO calendars without paying for a filings terminal.

Marketgenius is a free, mobile-friendly stock heatmap and lightweight stock dashboard site for quick visual discovery. It focuses on major U.S. index heatmaps, superinvestor portfolio heatmaps, simple stock fundamentals, ownership stats, valuation metrics, dividend details, short interest, and basic scores. Use it as a fast visual starting point, not as a full screener, deep financial terminal, broker, API, or valuation platform.

Short Interest - FMM is Find My Moat’s free high-short-interest stock tracker for users who want a quick searchable list of U.S. stocks with short interest above 20%. It is strongest for first-pass short-interest and short-squeeze discovery inside Find My Moat, with a sortable table and plain-English education, but it depends on an upstream source and is not a trade signal, export feed, or API.

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.

ORTEX is a market-data and analytics platform best known for short interest, securities lending, options flow, and trading-signal context. It fits active investors, analysts, and data teams that need more than a basic quote page, with deeper web-app and API access moving behind paid tiers.

Börsdata is a Nordic-first equity analytics, screening, and data platform for investors who want long-history fundamentals, thousands of ratios, strategy screens, ownership data, insider and short-selling context, technical charts, reports, watchlists, calendars, and API or spreadsheet access. It is strongest for Nordic stock research, while global coverage, holdings data, Excel/Sheets workflows, and REST API access depend on paid tiers and professional users are routed to Enterprise.

ChartMill is a browser-based stock screener, charting, ratings, alerts, and research platform for self-directed traders and investors screening U.S., Canadian, and European stocks and some ETFs. It is strongest for repeatable technical and fundamental screen workflows, swing-trading ideas, watchlists, alerts, market dashboards, ChartMill ratings, and strategy templates, but paid access does not turn it into a real-time broker or full portfolio accounting system.

Earnings Whispers is an earnings-event research site built around whisper expectations, earnings calendars, sentiment, grades, options context, and post-earnings drift signals. Use it as a setup and expectations tool around earnings, not as a guarantee that a stock will move a certain way.

FinancialData.Net is an API-first financial data platform for developers, analysts, spreadsheet users, and AI-agent builders who want broad market data, fundamentals, ownership, options, funds, ESG, calendars, news, Excel access, and MCP connectivity from one provider. It is strongest when breadth matters: stocks, ETFs, mutual funds, options, futures, crypto, forex, commodities, OTC securities, indices, filings-related datasets, and institutional/insider activity can sit behind one REST API. Serious use is paid, and compliance/security claims should be verified directly because the local profile does not include public audit reports.

HighShortInterest.com is a simple free list of U.S. stocks with short interest above 20%, organized by exchange for users who want a fast starting point for heavily shorted names. It is strongest as a no-login, read-only shortcut for short-interest idea discovery. It is not a full screener or institutional dataset: source detail, methodology, downloads, APIs, alerts, and real-time positioning are not provided, and the site itself tells users to verify the data elsewhere.

IBorrowDesk is a stock-borrow availability and borrow-fee tracker built around Interactive Brokers reported securities-lending data. It is useful for short sellers, event-driven traders, and researchers who want to monitor borrow availability, fee changes, and hard-to-borrow pressure on stocks and ETFs. The key limitation is scope: IBorrowDesk reflects IBKR availability and fees only, not the whole securities-lending market, and longer history or CSV exports require Patron support.

Nasdaq.com is Nasdaq's official investor portal for quotes, market news, screeners, calendars, filings, options chains, watchlists, and portfolio tools. It is strongest for investors who want exchange-branded market pages, earnings and dividend calendars, IPO context, ETF and fund screeners, company financials, insider and institutional ownership, and options-chain lookup without buying licensed exchange data products. Smart Portfolio Pro adds TipRanks-powered broker syncing and portfolio analytics. Nasdaq.com is not Nasdaq Data Link, a licensed exchange feed, a broker, or a professional market-data API.

SentiSense is a beta AI market-intelligence and data API platform for investors and developers who want stock data, sentiment, news clustering, social signals, institutional flows, insider trades, congressional trading disclosures, and AI-generated insights in one workflow. Search demand is small but commercially relevant around AI market intelligence and news sentiment APIs, so the copy should be precise about beta status, quota limits, and PRO-gated datasets. Use it as a signal layer for research, not as a broker or adviser.

MarketWatch is a Dow Jones financial-news and consumer market-data portal for stock market news, quote pages, watchlists, screeners, calendars, BigCharts, options chains, fund research, rates, newsletters, and paper trading through Virtual Stock Exchange. It is useful for retail investors who want mainstream market coverage and lightweight tools in one familiar site. Treat the subscription mainly as journalism access: market-data pages remain consumer-grade, exchange delays apply, and MarketWatch is not a broker, professional terminal, public API, or modeling platform.

GuruFocus is a value-investing research platform for investors who want global fundamentals, valuation tools, GF Score, GF Value, screeners, backtesting, guru and institutional holdings, insider trades, portfolio tracking, spreadsheet add-ins, and data/API access.

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.
