The Recast Way
Streamlined with AI
Without a doubt the best AI software out there. I used to pay somebody $1200 a month to repurpose my material and it rarely came out like I wanted. This tool allows me to take one of my video podcast and the software does the rest. Amazing how good it is at dividing up the content and then cutting it into great looking templates to load on social media. I now have a years worth of posts and it only took me a few hours. Buy it!
