What it is
Press record, talk over your screen or webcam, get a link. No editing, no file transfer, no scheduling. The recipient can watch at double speed and reply in text.
Best for
Asynchronous coaching. A three-minute video reviewing a client's lift video carries more than a paragraph ever will, and costs you three minutes instead of a booked call.
Watch out for
Free-tier limits on video length push you to be brief, which is mostly good. Anything containing health information needs the same care you would give any client record — check where the video lives and who can open the link.
