Professional estimates in minutes — just talk, snap, or type. Roy Estimator turns your job site walk-through into a professional estimate before you leave the driveway. Record yourself talking through the scope, and AI builds your estimate automatically. No more scribbling on notepads and retyping everything at home. VOICE TO ESTIMATE Walk the job site and talk through the scope naturally. Roy listens, understands trade language, and creates structured line items with quantities and pricing. Review, adjust, and send — all from your truck. PHOTO TO ESTIMATE Snap a photo of your handwritten notes or napkin scribbles. AI reads your writing and converts it into organized line items. No more retyping your field notes. TWO-SIDED ESTIMATES Keep your internal breakdown (materials, labor, markup) separate from what the customer sees. Send a clean scope of work with a total — no line-item pricing for customers to negotiate against. Just like you do on paper, but automatic.
