Fintel vs WhaleWisdom
Trying to decide between Fintel and WhaleWisdom? Here's how they compare on pricing, features, and platforms — and which one fits the way you invest.
Fintel
Best for short interest and which ETF includes this stock?
Platform for ownership, filings, short interest, and options sentiment with broad global coverage. Fintel publishes a Free column in its plan matrix and many public research pages can be viewed without a paid plan, but the current public signup flow does not expose a clearly labeled free-watchlist enrollment path. Treat custom dashboards, portfolio ticker lists, broker linking, and alerts as logged-in or plan-gated workflows rather than a confirmed free watchlist product. Paid tiers include Bronze, Silver, and Gold; premium features like the Workbench, Portfolio Builder, custom quant models, real-time options flow, unusual options activity, and Excel export are reserved for higher tiers. Broker account linking is supported via Plaid (U.S. only).
WhaleWisdom
Best for institutional data and investor holdings
Aggregates 13F filings, Schedule 13D/G data, Form 4 insider activity, and institutional ownership tools so investors can follow fund positioning, build watchlists/filer groups, export data, and backtest crowding strategies. Free access remains available with limited tools and recent 13F history; the pricing page says there are no trial accounts, while much of the site can be explored for free. Current paid plans are Standard at $90/quarter or $300/year, Pro at $150/quarter or $500/year, and Enterprise by quote for team access, unlimited 13F API access, live data feed calls, and nightly FTP files.
Outbound links may include affiliate or sponsor codes.
The verdict
The bottom line: Fintel and WhaleWisdom cover a lot of the same ground — 6 shared categories, including insider data, 13f, and 13d/13g — so for the basics you won't go far wrong with either. The real difference is focus: only Fintel gives you short interest and which ETF includes this stock?, and only WhaleWisdom gives you institutional data and investor holdings.
