   Perplexity Finance

   Perplexity Finance is an AI-assisted finance research experience that combines cited answers with stock, ETF, fund, crypto, options, news, charts, screeners, earnings documents, ownership data, government trading views, and a developer finance_search tool. It is strongest for quick cited research and agentic finance data access, but AI answers still need verification and consumer plans are separate from Agent API billing.

   FinancialReports.eu

   FinancialReports.eu is a public-company filings database, filings API, and hosted MCP server for analysts, AI-agent builders, and data teams that need fast document ingestion, Markdown extraction, watchlist alerts, webhooks, and filing Q&A across global markets. It is strongest when the workflow starts with filings rather than price charts: company documents, insider trades, IPO references, filing feeds, and programmatic document access are the center of the product. Free access is mainly for testing; Analyst or Enterprise is needed for serious API, MCP, AI chat, and production workflows.

   AUM 13F

   AUM 13F is a due-diligence web app for researching asset managers, institutional holdings, private funds, real estate managers, and limited-partner relationships from public filing sources. It is strongest for analysts who want a low-cost way to browse manager AUM, 13F holdings, EDGAR filings, IAPD records, CAFR-sourced LP portfolios, source links, portfolios, and alerts, but 13F data remains delayed and incomplete by design.

   SEC EDGAR - Company Filings (Full‑Text Search & Search Filings)

   SEC EDGAR Search is the official free source for U.S. public company, fund, insider, ownership, prospectus, and XBRL filing research. It is strongest as the source of truth for SEC filings, full-text search, latest filings, RSS feeds, CIK lookup, and data.sec.gov JSON APIs, but raw filings still require parsing and automated access must follow SEC fair-access rules.

   SecForm4.Com

   SecForm4.com is a U.S. insider trading and ownership monitoring site for Form 4, Forms 3 and 5, 13D/13G, and 13F filings from EDGAR. It fits users searching for SecForm4, insider trading trackers, Form 4 alerts, and 13D/13G monitoring, with free access for basic research and paid tiers for alerts, screeners, CSV downloads, and user-defined triggers. The right use case is monitoring SEC filing signals before checking transaction context, issuer fundamentals, and current ownership. It is not a broker, global insider-disclosure database, portfolio tracker, public API, or standalone buy/sell signal.

   13F Insight

   13F Insight is an SEC-filings intelligence platform for investors who want to track institutional 13F holdings, Form 4 insider trades, 13D/G ownership, watchlists, smart-money alerts, and AI answers grounded in filing citations. It is strongest for hedge-fund and institutional-ownership research, but 13F filings are delayed by design and AI summaries should be checked against the underlying SEC documents.

    Calcbench

    Calcbench is a professional SEC filing, XBRL, financial statement, disclosure, and Excel research platform for analysts who need traceable as-filed numbers, standardized accounting metrics, footnotes, redlines, proxy data, compensation data, M&A details, and API access. It is strongest for accounting-heavy U.S. equity research and data workflows, but meaningful access is priced for professional users and API access is sold separately from standard subscriptions.

    Changeflow (Trackly)

    Changeflow, formerly reached through Trackly, is an AI website-change intelligence platform for monitoring filings, regulator pages, IR pages, competitor pages, PDFs, feeds, and other online sources. It is useful for investment and compliance teams that want relevant briefings rather than raw page diffs, but it is not market data, trade execution, or a substitute for human review.

    SEC API (sec-api.io)

    SEC API is a commercial SEC/EDGAR API suite for developers, quants, compliance teams, and AI products that need fast filing search, real-time feeds, XBRL-to-JSON conversion, section extraction, insider filings, 13F data, and other structured regulatory datasets. It is strongest when you want production-ready normalized SEC data instead of building your own EDGAR ingestion stack, but the free tier is only a small starter allowance and redistribution requires enterprise terms.

    BamSEC

    BamSEC is a web-based SEC filings and transcripts research platform for investors and analysts who need faster EDGAR workflows. It is strongest for document search, filing redlines, table extraction, transcripts, insider and institutional ownership, watchlists, alerts, highlights, and source-link sharing, with most professional workflows gated behind Pro or Enterprise.
