The Best Koyfin Alternative for Analysts Who Need
Auditable Source Data

Data provenance. Koyfin sources equity fundamentals from S&P Capital IQ, which normalizes raw SEC filings into standardized templates for cross-company comparability. GeminIQ ingests data directly from SEC EDGAR and preserves the raw, as-filed reporting structure with XBRL tags on every data point. Koyfin offers far more breadth (global equities, ETFs, macro, FX). GeminIQ offers more depth and auditability for US-listed companies.

Both platforms now track insider transactions. Koyfin added insider ownership and transactions in April 2026 (available on Plus and above), sourced from S&P Capital IQ with up to 2 years of history and a summary chart. GeminIQ's insider tracking is sourced directly from SEC Form 4 filings, with a visual sentiment timeline showing executive buying and selling patterns, granular transaction-level detail, and context about each insider's role, with 17+ years of data. Both are useful — GeminIQ's approach is more tightly integrated with its as-filed data philosophy.

Yes — Koyfin has a global stock screener with pre-built templates and the ability to create custom screens across multiple asset classes. It's a strong, broad screener. GeminIQ's Advanced Screener is narrower but more precise: 100+ metrics derived directly from SEC filings, up to 10 stackable filter conditions with exact logic (less than, greater than, between), and every result traceable to its XBRL source. Koyfin's screener casts a wider net globally. GeminIQ's screener gives you auditable US results.

GeminIQ Founders is $29/mo billed annually — 26% cheaper than Koyfin Plus ($39/mo annual) and 63% cheaper than Koyfin Premium ($79/mo annual). GeminIQ includes all features at one price, with 17+ years of historical data. Koyfin's free plan is limited to 2 years of financials; its Plus plan gives 10 years. Premium unlocks unlimited custom formulas and priority support. For US-focused analysts, GeminIQ offers more historical depth and data auditability at a lower price.

No. GeminIQ is specialized for fundamental equity analysis of US-listed SEC filers. Koyfin's economic data dashboards — covering FRED indicators, currency charts, bond yields, and macro overlays — are among its strongest features. If macro context is central to your workflow, Koyfin serves that need well. GeminIQ is the better tool when your primary research is company-specific US fundamental analysis and you need the underlying data to be verifiable.

No. GeminIQ is focused on structured quantitative analysis — XBRL-traceable data, interactive visualizations, screener, and the Earnings Heatmap. Koyfin's AI Copilot offers conversational research capabilities for quick-look analysis. If AI-powered Q&A is important to your workflow, Koyfin provides that. GeminIQ's value is in the precision and auditability of the data itself.

Koyfin's free plan offers real value — charting, macro dashboards, and 2 years of financials. But 2 years of history isn't enough for full market cycle analysis, and the free tier uses the same normalized S&P Capital IQ data as the paid plans. GeminIQ's 7-day trial gives you the full platform — 17+ years of XBRL-tagged data, the Earnings Heatmap, advanced screening, insider tracking, and institutional ownership — so you can evaluate the difference raw source data makes before committing.
