Output

96 mentions across 6 sources · 17% positive — critical (weighted across 6 sources)

Hacker News, YouTube, Product Hunt, App Store, Stack Overflow, Lemmy

Presto Voice

25 mentions across 2 sources · 46% positive — mixed (weighted across 2 sources)

App Store, Lemmy

What users praise

What frustrates them

  • • Pricing is contact-only, making budget comparison difficult for buyers
  • • Product is a managed partner play, not a voice stack operators can tune
