"What did Korea's pension giant buy yesterday?" "Which stock did Warren Buffett add this quarter?" The answers are all in public filings β scattered across Korea's DART system, SEC EDGAR, and government open-data portals, where almost nobody has time to dig. WhaleLens collects and organizes those filings automatically, putting the moves of Korea's $750B+ National Pension Service (NPS) and the world's legendary investors on a single screen. β NPS disclosures, the moment they drop When NPS crosses or changes a 5%+ stake in a listed company, a mandatory filing is published. WhaleLens collects each filing, lays out the stake change and share count, and tracks the previous report to compute how much was actually bought or sold. β’ 5%+ bulk-holding change reports β increases and reductions at a glance β’ 10%+ core shareholder reports β real change rates vs. the previous filing β’ Telegram channel β instant alerts on new disclosures β The full NPS portfolio, made transparent β’ Top 200 Korean equity holdings β portfolio weight, per-company stake, year-over-year change β’ Per-stock detail pages β multi-year NPS stake history charts β’ US equity portfolio from SEC 13F β quarterly share changes, new positions, full exits β Quarterly rebalancing of the legends Track the 13F filings of Warren Buffett (Berkshire Hathaway), Cathie Wood (ARK), Ray Dalio (Bridgewater), Bill Ackman (Pershing Square), Michael Burry (Scion), Stanley Druckenmiller, Seth Klarman and more β ten investors, every quarter. β’ What they added, trimmed, opened, and fully exited this quarter β’ Pick any stock and see which masters hold it together β Smart Money Consensus β an analysis you won't find elsewhere WhaleLens overlaps the holdings of NPS and the legendary investors β eleven giant funds in total. A stock held by eight institutions at once tells a different story than one held by a single fund. The holder-count ranking surfaces where giant capital agrees. β Built for β’ Investors who track institutional and pension-fund flows β’ Value investors who benchmark the portfolios of Buffett, Dalio, and other masters β’ Anyone who wants data-driven judgment without digging through filings β Sources and reliability Korea's DART regulatory filings, SEC EDGAR 13F filings, and Korea's open data portal (NPS) β all official government and regulatory disclosures, refreshed automatically. β» This is an independent service, not affiliated with the National Pension Service or any government agency. It organizes publicly available filings. β» Nothing in this app is investment advice. Automated collection may contain errors; investment decisions are your own responsibility.

Verdict
The clearest difference is in-app purchases: WhaleLens at none against Alpha Sight's 2. WhaleLens also leads on iOS requirement (13.0 vs 15.0). Alpha Sight's advantage is ads (none vs shown) and update cadence (every 8 days vs every 3 weeks). On price and device support there is nothing between them.
