Sharing a tool I keep coming back to: Flow AI turns a text prompt or a single still into a short clip right in the browser, and it does not ask you to create an account first. I use it for rough concept boards - a few seconds of motion to check whether a shot idea reads before I spend time on a proper render. The image-to-video mode gets the most use, since most of my ideas start as a still. Free tier is enough for sketching. Curious what other people here reach for when they just want a quick visual test.
