12ft.io
This tool removes paywalls from websites. It benefits from the fact that the Google crawler will cache a copy of the site every time it crawls it. All they do is show you that cached, unpaywalled version of the page. Nevertheless, it will not stop you from contributing if you like the content provided. Bypass any paywall, https://12ft.io/

LICEcap
LICEcap can capture an area of your desktop and save it directly to an animated GIF (for viewing in web browsers, etc). This way you can make a short video (an animated screen capture) without actually making a video file. It’s much smaller and is really useful for quick explainers.
