It offers "Overdub", but they suggest limited use of it (replacing 1-2 words), not full podcast creation. The quality of the text-to-speech model they use is not at the same level as the ElevenLabs model we are using, so I think someone would struggle to create an engaging podcast using Overdub. I'd also think that this is not a direction that Descript would be heading to, as they have built a successful business as a "podcast editing" platform and catering to "podcast creation" would be a significant change.
In addition to this, given that we are a "podcast creation" platform rather a "podcast editing" platform, we have focused on integrating functionality that allows users to go end to end in creating a podcasts. Examples: publishing a podcast (RSS), generating a video automatically, providing a shareable podcast page, autotranslating the podcast to other languages and a lot more.
For substackers that already have a podcast, that’s a separate question. Ultimately it depends on if they think that they can use the time the put in for the recording and editing process to some other creative process and use Wondercraft for generating the audio. Haven’t seen that many existing Substack podcasts for this use case to become that prevalent.
