What's New in Prentis
1.0.3
September 2, 2026
Prentis now greets you by voice the moment you open a conversation — from the Ask Prentis tab or from any job — and asks for the nameplate and what the unit is doing, so you can just start talking. Speech recognition is upgraded for clearer transcripts on noisy job sites, and Prentis is quicker to reconnect if your signal drops mid-call.
