We use both Milk and Descript at Macro for our podcast workflows.
Milk is really good at creating short (for us it's ~1min), impactful Twitter + LinkedIn marketing collaterals based on each podcast guest (we can add our logo, the guest's background, the guest's bio + picture, transcript, etc.).
Descript is amazing at editing the entire podcast and make sure we have the overall content needed to publish.
Can't imagine doing our podcast without Milk + Descript.
