One system that makes the delivery promise — and keeps it
The slot booked at checkout, the store assigned, the route planned, and every customer notification all derive from the same order record, eliminating manual re-entry between checkout and routing tools.
Set capacity, cutoffs, and prep time for every location and slot, watch remaining capacity as orders book, and route each order to the location that actually made the promise.
Plan multi-driver routes in one pass, split shipments across drivers, and let drivers work each route from a mobile app with photo proof at handover.
Customers receive out-for-delivery and delivered updates on their preferred channel, with at-risk alerts surfacing before a window is missed — targeting fewer WISMO contacts and delivery disputes.
Text to speech and voice AI across every device
Listen to books, PDFs, documents and web pages read aloud in a large library of lifelike AI voices.
Dictate instead of typing in almost any app, across Google Docs, Gmail, Slack, Outlook and more.
Turn documents or a short prompt into an AI podcast, and get instant summaries of what you are reading.
Use the web app, Chrome and Edge extensions, and native iOS, Android, Mac and Windows apps.
