Peek is the fastest way to create short screencasts of a specific area of your screen. Simply hover over an area you want to record and press "Record".
Peek records your screen in real time, captures mouse movements, and allows you to specify an optional audio comment for each recording. After the recording is done, just press "Done" to get your GIF right away.
If you do not like the result or if it misses something, just edit it with all the other tools on Codepen.
