Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Auphonic

  • The free tier covers 2 hours of processed audio a month
  • Billing is by audio duration with a 3 minute minimum per production, so many short clips cost more than the running time suggests
  • Multilingual speech recognition, automatic chapters and show notes all require a paid plan
  • Watch folders, batch productions and team accounts are paid features
  • Free output carries an Auphonic jingle

Postmark

  • Free tier caps at 100 emails per month with no overages allowed
  • Basic plan ($15/mo) includes 10,000 emails then charges $1.80 per 1,000 extra; Pro and Platform tiers have their own lower per-1,000 overage rates ($1.30 and $1.20), so cost scales per email beyond the included volume
  • Custom high-volume pricing above the published tiers requires contacting sales
