What's New in Prentis
1.0.1
August 19, 2026
Prentis now runs a call the way a senior tech does. It works through the whole system before the money conversation, keeps a running list of what it finds, and brings you one set of findings to take to the homeowner instead of stopping you at the first problem. ONE APPROVAL CONVERSATION Findings get noted as you work and presented together, so you are not walking back to the customer three separate times. When you are ready, Prentis lays out what needs doing today and what protects the system long term, and you take that to the homeowner as one ask. APPROVALS THAT HOLD UP What the customer approved, and when, is kept straight for the whole call. Find something new after work has already started and Prentis treats it as its own conversation instead of quietly folding it into the first yes. A customer who wants to think it over is recorded that way, not as a no. A CLOSE OUT THAT TELLS THE TRUTH Your close out shows the work you actually completed, listed separately from work that was approved but is not done yet. Anything the customer turned down is documented with what to watch for. SMOOTHER ON VOICE Spoken answers play through without dropping out partway. Prentis also stops repeating itself when it has already asked you something. CLEANER UNIT HANDLING Photograph two different units in one go and Prentis asks which one you are working instead of mixing their specs together. Read a measurement out loud and it takes you at your word rather than asking you to take it again. Pricing stays yours. Prentis never quotes a number.
