What real users say: Cero 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.

Cero

83 mentions across 6 sources · 24% positive — critical (weighted across 6 sources)

Hacker News, YouTube, Product Hunt, App Store, GitHub, Lemmy

What users praise

  • • Purpose-built for LatAm healthcare, with WhatsApp-first design matching regional communication habits
  • • Deep EMR integration list (Tasy, MV, Pixeon, Soul MV) is broader than most generic competitors
  • • No-code workflow builder lets clinic ops teams design patient journeys without engineering help
  • • Founder has real clinical experience as a practicing dentist, giving the product credible domain empathy

What frustrates them

  • • No free tier or trial, so clinics must commit $500/month after only a sales demo
  • • Nearly zero independent user reviews or case studies to verify no-show reduction claims
  • • Brand name collides with unrelated products, making search and patient trust harder
  • • Customer support quality and response times are completely unverified in community data

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

Who should pick which

  • QSR chain operator (multiple drive-thru locations)
    Pick: Presto Voice

    Presto Voice is designed for drive-thru automation with up to 95% non-intervention rate and upselling engine proven to lift revenue 6% (e.g., Dairy Queen partnership).

  • Hospital operations manager in Brazil
    Pick: Cero

    Cero automates patient communication via WhatsApp/voice, integrates with local EMRs (Tasy, MV), and reduces no-shows in LatAm healthcare.

  • Independent fast-food restaurant owner
    Pick: Presto Voice

    Not recommended for both: Presto targets chain scale, Cero is healthcare-only. Consider lighter alternatives like self-serve kiosks.

  • Latin American clinic administrator
    Pick: Cero

    Cero's no-code workflow builder and EMR integrations streamline appointment reminders and surveys in Portuguese/Spanish.

  • Global franchise network (QSR)
    Pick: Presto Voice

    Presto supports multi-location deployment and menu unification, suitable for franchises aiming for consistent voice AI across locations.
