13F Insight

13F Insight pulls institutional holdings, insider trades, and ownership filings into one research workspace. Its AI can answer questions with filing citations, but the filings arrive late and the generated summaries still need a check against the SEC documents.

AlphaResearch

AlphaResearch puts filings, transcripts, press releases, estimates, news, insider trades, ownership, and fund holdings in one searchable workspace. It is aimed at document-heavy research. Global coverage and spreadsheet add-ins require Enterprise, and the premium trial asks for a card.

It brings together AUM, 13F holdings, EDGAR, IAPD, CAFR-sourced portfolios, source links, and alerts. The underlying filings are still delayed and incomplete.

Börsdata

Börsdata gives investors long-history Nordic fundamentals, ratios, screens, ownership, insider and short-selling data, technical charts, reports, watchlists, calendars, and spreadsheet or API access. It is strongest for Nordic equities. Global data, holdings, Excel or Sheets workflows, and the REST API depend on the plan.

Business Quant covers U.S. company fundamentals, operating KPIs, segment data, analyst estimates, institutional ownership, and insider trades. It is useful when company-specific operating measures matter alongside standard financial statements. The free plan limits KPI history and API usage, while paid plans increase history and usage allowances.

BuySide Digest is a free searchable collection of hedge-fund letters, manager commentary, tickers, themes, quarters, 13F context, and investment pitches. It is useful for qualitative idea work and alerts when new letters appear. The documents are public, delayed, and opinions rather than live signals.

ChartMill

ChartMill is a browser screener and charting service for U.S., Canadian, and European stocks and some ETFs.

Fintel

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. Premium data, exports, options flow, AI, and portfolio tools depend on the plan, and the signals are inputs rather than recommendations.

GeminIQ

GeminIQ organizes U.S. 10-K and 10-Q data into financial statements, calculated metrics, charts, tables, screens, watchlists, ownership views, and post-filing price analysis. Values retain XBRL tags and links to SEC filings, but new data arrives the next day rather than live.

Quiver Quantitative provides dashboards, screens, alerts, backtests, and APIs for political trades, insiders, institutions, lobbying, government contracts, patents, apps, ETFs, dark pools, and other alternative data. Web Premium and Quiver API are separate products, and the signals can be noisy or delayed.

Screener.in

Screener.in is an India-focused stock screener with company pages, custom queries, watchlists, alerts, exports, filings, shareholding data, and Screener AI. Its free plan is useful; paid plans add exports, alerts, peers, segments, concall notes, product trends, and AI credits. It is not a global broker.
