What users praise

Presto Voice
37 mentions across 3 sources · 32% positive — critical (weighted across 3 sources)
YouTube, App Store, Lemmy
What users praise
- • Handles POS and headset integration itself, so voice AI goes live in an active lane without pausing service
- • Built specifically for multi-location QSR franchise groups, not single shops or dine-in concepts
- • Continuous upselling of add-ons and specials on every transaction targets average-order-value lift
- • 24/7 drive-thru ordering availability removes the labor constraint of shift coverage at the speaker post
What frustrates them
- • Almost no independent, on-topic community reviews — the dataset is dominated by unrelated same-name products
- • Vendor-published KPIs (95% non-intervention, 88% upsell, 6% lift) lack third-party verification
- • Won't hand over the model to tune, which blocks teams that want to own and iterate on the voice stack
- • Only Toast is documented as a named POS integration in the available data
