I've tested this out on ten episodes of my podcast and it is just not good. I wanted really bad to like this and use it which is why I have it several months but it has not improved.

The AI constantly mixes up guests, misquotes, mislabels the speaker (even with M&F voices).
The titles it produces are weird and generic.
The Bios are always wrong, even with repeat guests.
The Introductions it writes are ridiculous- seriously, you've listened to me speak for 15 hours and you think that's how I talk?
The Quotes, Hooks & Timestamps pick up in the middle of a sentence so it doesn't make any sense.
The Reel Scripts are more nonsense. "Hey Instagram Entrepreneurs!" (It's a sports show)

The Timestamps improved on the 10th try. Before that it would timestamp nearly every sentence.

At most I get a few sentences that are useful to me and that's not worth it to upload and sort through the word salad. My time would be better spent just writing the sentences myself.

I'm going to stop using it now. Hopefully the Castmagic team improves the product for others.
