> If you are showing off some beautiful TLI, an interactive prompt or ascii animations, this is the perfect tool.
If you want to just show something off, a GIF (or real video) is the answer.
The defining feature of asciinema is that you can copy the text out of the animation. Which is actually not that useful most of the time, because you can't search for text in asciinema (AFAIK?) like you can in, well, documentation.
