Short legth limits, audio captioning, using audio from another video so you don't have to talk, easy text placement (again, so you don't have to talk), all videos are vertical, ability to respond to a comment with a video (and encouraging it by imposing 150 char limit), responding to another video with video (including part of it for context), ability to download videos (so you can play or edit them however you want),

— and that's just off the top of my head on the content creation side. Off the top of my head.

Most importantly, it's that algorithm does a good job at bringing you the right audience, having one-click promotion tools, having detailed analytics, etc.

If you don't see this as accessibility features, well, that's my entire point.

The net result is that a TikTok post can start a conversation, with videos. And someone just talking - or just acting to audio - is first-class content. As is just showing a slice of your life and slapping some text on it.

Even if you make such content on other platforms, it'll have zero reach there. You have to do much more work to have people watch a video on IG or FB (people would just scroll past your video without playing it), or YouTube (whose UX strongly favors long videos, otherwise it's too many clicks).

The effort required to make a video for other platforms that people would see is a barrier that TikTok creators don't face.

This applies to everyone, but neurodivergent people benefit from it especially.
