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.
