Marketcaper lookup extensions
Seven category-specific browser extensions for selected-text market size lookup across stocks, ETFs, funds, crypto, billionaire net worth, money, fiat currencies, and GDP.
Stock market cap browser extension
Select a public-company ticker or name on any webpage, click the Marketcaper icon, and see the latest available stock market cap and price context.
ETF AUM browser extension
Highlight ETF tickers and names while reading, then open a Marketcaper card with latest available AUM, fund size, and price context.
Mutual fund AUM browser extension
Select mutual fund tickers and fund names on webpages, then check latest available AUM, fund size, NAV, or price data in a Marketcaper card.
Crypto market cap browser extension
Highlight crypto symbols or coin names while browsing and open a Marketcaper card with latest available market cap, price, rank, and comparison links.
Billionaire net worth browser extension
Select a billionaire name while reading and open a Marketcaper card with latest available net worth context and comparison links.
Money browser extension
Highlight money, fiat currency codes, or currency names and open a Marketcaper card with FX market cap, M2 money-supply context, and rates where available.
Country GDP browser extension
Select a country, region, or GDP entity while reading and open a Marketcaper card with latest available GDP size context and comparison links.
Built for selected-text lookup, not page scraping
Each extension checks selected text locally first. Marketcaper receives the selected text only when you click the floating icon or use the right-click lookup action, and each public extension searches only its own category catalogue.
Chrome Web Store and Firefox Add-ons install links will be added here after each category extension listing is approved.
