Yes. Most major websites (like WSJ, NYT, Wired, etc.) are supported.
Above is a WSJ coverage behind a paywall. And here is the screenshot taken behind the paywall: https://test.clipcoverage.com/coverage/screenshot/145z6le7SLP5YasdDBjr0Bown8Zzyr4PEN9K81BCXG-8/4026
If a website you need is not supported, please tell us and we'll consider adding it.
