Field24 vs.
Claude
Claude is a general-purpose AI assistant. It is excellent at reading and writing, and it can look at a page of a plan. Field24 is the same kind of intelligence, pointed at one job: turning a plan set into a priced, defensible estimate.
No install. No training. Send a plan set and see your first takeoff in minutes.

Field24 reads the plans for you
Claude estimates a wall by eye and calls its own counts approximate. Field24 measures the drawing's geometry and marks every quantity on the page.

Exact lengths from the drawing itself
Wall lengths read straight from the PDF's vector layer, not guessed from pixels.
Walls, doors and windows on scans too
A floor-plan detector finds walls on scanned sheets and counts the openings along them.
Every row shows its work
Tap a row and the sheet opens with that measurement highlighted.
Local pricing, not a national average
A general assistant has no price feed. Field24 looks them up: Home Depot prices for residential work, market rates from private cost databases for commercial work, plus labor rates adjusted to your ZIP, and shows you where each number came from.
Residential at Home Depot, commercial at market rates
Residential work is priced at Home Depot, in the US or Canada, with the product, pack size and list price on every row. Commercial work is priced at market rates from private cost databases.
Labor rates for your area
Hourly rates by trade are adjusted to your location from the 2026 National Construction Estimator, and your own saved rates always win over the market.
Your price book, your markup
Upload a supplier price list or a past estimate and Field24 prices from your book first. Overhead, profit and contingency are yours to set.
Minutes, not a training course
With a general assistant you are the workflow: upload, prompt, check, reformat, repeat. Field24 already knows the steps. Send the plans on WhatsApp or the web and the takeoff, the pricing and the proposal come back in minutes.
Send the plans
Text them on WhatsApp, drop them in the web app, or forward the bid email to your Field24 address. PDFs, photos, even a voice note about the scope.
Answer two questions
Your ZIP code and the scope you are bidding. That is the whole setup. No templates to build, no cost book to load first.
Review it on the sheet
The takeoff comes back priced, with every row marked on the drawing. Adjust what you want, then send the proposal for signature.
WITH Claude
You run the process
Easy to start; reliable measurement is the hard part.
WITH
The process runs for you
Most contractors get their first takeoff back within minutes of sending the plans, and learn the tool by using it once. There is nothing to install and nobody to train.
Times depend on the size of the plan set. A typical residential or light commercial set is measured and priced in minutes; large sets take longer.
When Claude is the right call
Claude is a superb writing and research partner, and plenty of contractors use it for emails and contracts. For measuring a drawing and pricing it, you want a tool built for the task.
