  • • Notion-style editor with Markdown/MDX and Git sync for docs-as-code.

What frustrates them

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
