I've found asciinema pretty cool and recorded a few recordings of things I've done, like some experimental Emacs commands, a computer algebra system, a Unicode Tetris game in ARM assembly, and a minimal roguelike: https://asciinema.org/~kragen. These are not the most spectacular recordings on the site, but I have found them a useful way to communicate ideas.

I wish there was some kind of voiceover support.

One thing to be aware of before you try it is that, if you make a recording without providing a filename for it, it uploads it by default to the web site, even if you haven't created an account yet, though it doesn't make it public. So maybe don't record anything you have a responsibility of confidentiality for, or patch out that feature.

Since 3.0 (Rust rewrite that is already shipped by Arch et al), the filename argument is required, and it simply saves it locally by default without even asking to upload.

upload is a separate command.

If you want voiceover and more you might wanna check out CodeMic.io.

		That's not just proprietary, it's surveillance capitalism. "Subscribe for early access and monthly progress updates." You should be embarrassed for posting that kind of filth on a thread about asciinema, which is a free-software program that works offline and has strict privacy protections. Also, codemic.io seems to be oriented toward full-motion video, so aside from the authoritarianism issues, it's not even related.

That is so shady.

		I can see why you think that but Asciinema's whole original purpose was to share quick recordings. IIRC you actually had to go out of your way to just save locally, as it's main advertised and very obvious functionality was that it was uploaded. They've since made things a little more flexible, but I don't perceive it as being shady. If you used it you were most likely after that functionality.

		It's kind of justifiable in the sense that it's more convenient in the usual case. You say `asciinema rec`, do your thing, and then you have a secure URL to share with somebody, and you can make it public with a couple more clicks. Actually I think this has changed, because when I tried this just now, it asked me `(s)ave locally, (u)pload to asciinema.org, (d)iscard [s,u,d]? u` which is a little more friction but probably a safer default.

		It was developed as a tool for the website, not a general purpose screen recording tool. The latest version has evolved to be more general purpose without assuming the upload.
