Second Brain

92 mentions across 6 sources · 49% positive — mixed (averaged across 6 sources)

Hacker News, YouTube, Product Hunt, Bluesky, GitHub, Lemmy

Presto Voice

45 mentions across 3 sources · 32% positive — critical (weighted across 3 sources)

YouTube, App Store, Lemmy

What users praise

  • • Fifteen-plus years in restaurant automation gives Presto real QSR operational experience
  • • Handles POS and headset provider integration itself, avoiding a lane shutdown at install
  • • National rollouts at Wienerschnitzel, Taco John's, and Dairy Queen validate enterprise scale
  • • Spectrum-of-models approach targets store-by-store variation in menus, accents, and ambient noise

What frustrates them

  • • No independent operator reviews exist in the public data to validate the 95% claim
  • • Vendor-published metrics lack third-party audited baselines or methodology
  • • Only Toast is named as an integration — other POS stacks are unproven
  • • Pricing is undisclosed, making per-lane ROI modeling impossible up front
