I've been a Shadow user for well over a year now and find it a major part of my workflow.
I was first drawn to Shadow due to its offline transcription. This is a considerable plus in highly regulated industries. The automation of skills is also another great time saver, such as exporting Markdown meeting notes to a folder for synchronization or connecting with Obsidian and other note-taking apps.
Now they've introduced screen recording, which gives the models much more context about what you were doing. This should be a significant boost in productivity and recall.
It would be difficult to keep up with work without it. I don't know how I—or anyone else—got by without it before it existed.
