The best AI for estimating in 2026

  1. 01

    Field24

    Our pick

    Best overall: plan set to priced proposal in minutes, with every quantity marked on the drawing with assumptions highlighted for your review.

  2. 02

    Togal.AI

    Best for teams that live in a takeoff workspace all day and already price in separate estimating software.

  3. 03

    Handoff

    Best for remodelers who rarely work from full drawings and want a polished proposal from a description of the job.

  4. 04

    Panel AI

    Best for contractors who already have the plans in hand and want an AI takeoff turned into a proposal inside one web app.

  5. 05

    PlanSwift

    Best for experienced estimators who want full manual control and a mature assembly library on Windows.

  6. 06

    On-Screen Takeoff

    Best for estimating departments that have standardized on ConstructConnect's On-Screen Takeoff and Quick Bid.

  7. 07

    Claude

    Best for writing: bid emails, scope narratives, contracts and RFIs.

  8. 08

    ChatGPT

    Best for everyday writing help: emails, scope narratives and quick questions.

Accuracy on real plans

The question that matters is whether the numbers are right. We ran Field24, Claude and ChatGPT on the same real plan sets and scored each takeoff against a professional estimator's.

Takeoff accuracy on real commercial plans
AIAccuracy
Field2488%
Claude77%
ChatGPT71%

Up to 88% depending on the trade: this is drywall and framing, scored against takeoffs by professional estimators on the same plans, with individual plans as high as 96%. On complete, all-trade takeoffs it also came out ahead of both. How we test ↗

What to look for in AI estimating software

  • It measures, not guesses. Quantities should come from the drawing's geometry, with a mark on the sheet you can check.
  • It prices for your area. Material and labor rates should be local and show where each number came from.
  • It reads the notes. Wall heights, wall types and full-height callouts change the quantity more than the line length does.
  • It fits how you bid. Bid-board intake, email and your phone, not another program to learn.
  • It finishes the job. A takeoff is half an estimate; you need pricing and a proposal you can send.
