Cons
Entry-tier download and transcription-credit limits may be restrictive for fast-growing shows

Entry pricing is higher than some no-frills podcast hosts

Built-in monetization tools like dynamic ad insertion and listener donations
Automatic distribution to all major podcast directories

Includes AI transcripts and audio-to-video conversion on paid tiers
Cons
Lower-cost pricing shown on the site is tied to annual billing, so monthly billing costs more
