What real users say: Carly AI vs Presto Voice

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

Carly AI

No verifiable community signal. We scanned public discussion on Aug 24, 2026 and found posts matching the name “Carly AI”, but could not establish that they are about this product rather than something else sharing its name. Rather than publish a score built on the wrong subject, we publish none.

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
