How it works
1
Upload

Drop in the PDF

Every page lands on your phone with a real thumbnail. Open one, pinch, zoom. Takes about as long as finding your tape.

Auto Sort

Roughin files it

On Solo and Pro, every sheet gets a trade, a number and a name. Architectural here, Electrical there. You stop scrolling 48 pages for one plan.

Ask

Ask it like you’d ask the foreman

“What’s the ceiling height in the kitchen?” The answer comes back with the sheet it’s on. Tap it: the page opens, the spot’s boxed.

Work

Do the math where you stand

Feet-inch keypad. Fractions. No signal needed. Send the result to a note on that sheet so it’s still there tomorrow.

What’s inside

Ask the plans

“Where’s the kitchen sink rough-in?” Answered from your set, sheet named. Tap the sheet and it opens with the spot boxed.

Auto Sort by trade

Every sheet filed under Architectural, Structural, Electrical, Plumbing. Numbered, named, with a real thumbnail of the page.

Construction calculator

A feet-inch keypad that takes fractions, plus Triangle, Areas, Volumes and Convert. Works in the basement.

Notes & markups

Circle it, arrow it, write on it. Pin notes to a sheet, send a calc result straight into one, share the marked-up sheet as a PDF.

Measure on the sheet

Tap two points, get the distance in feet-inches or metric. Roughin reads the sheet’s scale, or you calibrate off a dimension you trust.

Sheet stacks

Pick up to 6 sheets and swipe between them. Floor plan, ceiling plan, structural, without going back to the grid.

Your own sets

Build custom sets, rename groups, move the sheet the AI filed wrong. Your set, your labels.

Find on plans

Search sheet names, room labels, notes, dimensions and legend entries across every project you own.

Upload, viewing, the calculator and notes are free. Auto Sort, Ask AI, measuring, markups and custom sets need Solo or Pro. Sheet stacks are Pro.
