Manuskript might be a bit more popular than Api.ai. We know about 1 link to it since March 2021 and only 1 link to Api.ai. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Also, when I try to find more help in the AutoVoice documentation/help menu under the Advanced Commands section it points me to an outdated dead end: a now "private" YouTube video and the URL https://api.ai which is a dead URL. Source: almost 4 years ago
Looks like you want something that integrates well with your workflow. The closest to your description seems to be Manuskript although I haven't used it. But your requirement of "keeping notes and frameworks and linking back and forth" should be possible by stitching together existing Linux tools using a syntax like markdown or asciidoc so that you can use any text editor to write your story and use external tools...
