Loom
A convenient screen recording. Both its name and recording functionalities are similar to that of Zoom. Good for making comments on stuff that requires a visualization, such as UX design, talking and screenshot may not be as intuitive and a video.
A picture is worth a thousand words :)
Chrome Extension support recording resolution up to 720p. Downloading a desktop app allows you to record up to 4K.
Recorded videos are uploaded to Loom's cloud storage, and will be immediately available after recording finished. A url to the video will be automatically generated and saved to your clipboard.
After sending a video url to someone else, they can comment on your video with loom too.
Basically, this is a messaging and commenting app using videos.
This app is perfect for me as I love to show off the progress of my project progress with others.
Embed
Moreover, the video can be embedded in other pages such as notion. Embedding video explanation in blog is a good choice.
