What it does

The tools you reach for, and the ones nobody else ships.

Everything a modern PDF and takeoff workflow needs, from redlines to real quantities, with automation and a private estimator layered on top.

Markup & measure

Calibrate once, then measure length, area, volume, angle and count. Clouds, callouts, stamps, highlights, redaction and digital signatures: the full set, with snap-to-geometry precision.

Construction takeoff PRO

Quantities attribute to spaces and systems and roll up in a live panel as you draw, then export to CSV or multi-tab Excel with budgetary ranges and labor hours by craft.

AI Auto-Takeoff PRO

Detect every room and name it from the drawing's own text, trace wall and pipe runs into linear measurements, and count repeated symbols across a sheet, in a single click, ready to price.

On-device AI estimating PRO

When you're ready to price, one click turns a takeoff into a professional basis of estimate: executive summary, scope, assumptions and risk flags, written by a bundled AI model that never touches the internet.

The difference · TRACEBUILD Pro

Your estimate is written on your machine.

TRACEBUILD bundles a professional-grade AI model that runs entirely on your computer through a local engine. Your priced takeoff becomes a client-ready narrative. No account, no upload, no internet required. The dollar figures stay authoritative; the AI writes the scope, assumptions and review around them.

  • 100% private. Client drawings never leave your machine, a real data-privacy guarantee, not a policy.
  • Works anywhere. Jobsite trailer, plane, or a spotty connection: it runs fully offline, out of the box.
  • Grounded in your numbers. Executive summary, scope by system, inclusions & exclusions, assumptions, value-engineering ideas and possibly-missing scope.
Every tool, in one place

The complete PDF markup toolkit. Then everything else.

A full, professional PDF markup, measurement and document toolkit is the foundation of TRACEBUILD, the tools professionals use every day, in a fast, modern interface. Takeoff, estimating, collaboration and AI are layered on top as added value. Markup and measurement ship free in Lite; deeper takeoff, estimating and collaboration unlock with Pro.
