The title is a claim worth defending: “from 45 minutes to 5.” The actual data is even more dramatic. A University of Kansas peer-reviewed study published in 2025 found that Togal.AI completes takeoffs 76% faster than traditional takeoff software. A manual roof takeoff that takes 6 hours takes 45 minutes with AI, with the AI handling the first pass in about 1 minute and the estimator spending 30 minutes reviewing and adjusting the output.
A 3 to 4 hour residential bathroom estimate, with AI generating the scope and itemized line items, now takes 20 to 30 minutes for most remodelers. At 5 bids per week, that’s 15+ hours recovered every week from this one workflow alone.
The adoption numbers reflect the opportunity: 37% of construction firms were using AI in 2025, up from 26% in 2023. The contractors in that 37% are submitting more bids, winning more work, and running circles around competitors who are still doing estimates manually.
What type of contractor are you estimating for?
AI estimating tools split into two categories: takeoff tools (reading plans and measuring quantities) and proposal/quote generators (turning scope and quantities into priced proposals). Some tools do both. Here’s which category fits your work:
- General contractors and commercial trades working from architectural plans: You need a takeoff tool. Togal.AI, STACK, ProEst.
- Residential remodelers who scope in person and build proposals from conversation: You need a proposal generator. Handoff AI, Houzz Pro AutoMate, ChatGPT with templates.
- Field service (HVAC, plumbing, electrical) building estimates on site: You need a mobile estimate builder. JobNimbus Scout, ServiceTitan AI Estimator, Housecall Pro.
Togal.AI: Best for Plan-Based Takeoffs
Togal.AI uses proprietary AI trained on AIA (American Institute of Architects) measurement standards to automatically detect, label, and measure spaces, walls, and structural elements from uploaded plans. The “Togal.CHAT” feature lets you query plans in plain language: “What’s the total square footage of all bathrooms on floor 2?” “How many doors are there on the east wing?”
Published performance data:
- 76% faster than traditional takeoff software (University of Kansas peer-reviewed study, 2025)
- Up to 98% accuracy on structured project types
- Under 5% variance from manual takeoffs
- 20.4% improvement in overall estimate accuracy when AI is used vs. manual (independent analysis)
Customer examples: NC Painting went from 19 bids per month to 60 in 60 days. UrbanCore Construction reduced conceptual estimates from over a week to hours. DPR and Clark are among the enterprise customers using it at scale.
Pricing: $299/month per user, billed annually ($3,588/year). Enterprise plans for 3+ users require a custom quote.
Best for: General contractors, commercial subcontractors, and specialty trades bidding from architectural drawings. The ROI is clear when you’re doing 5+ plan-based takeoffs per week.
Handoff AI: Best for Residential Remodelers
Handoff AI is built specifically for residential remodelers who estimate from site visits rather than architectural plans. You describe the project (type, square footage, location, scope, quality tier) and Handoff generates an itemized estimate with labor and materials, built on a database of real residential construction costs.
From the estimate, it generates a professional proposal with client management, digital signature capability, and invoice creation. The full workflow, from site visit to signed proposal, compresses from a multi-day process to same-day delivery.
Pricing: Starter at $39/month, Business at $119/month. The most affordable AI estimating entry point in this category.
Best for: Bathroom remodelers, kitchen remodelers, and general residential contractors who estimate from scope rather than plans. The residential cost database is the key differentiator versus using a general AI tool like ChatGPT.
Houzz Pro AutoMate: Integrated with CRM
Houzz Pro’s AutoMate feature uses Google Gemini AI with location-aware pricing to generate estimates from text or voice prompts. You describe the project and it outputs itemized labor and materials with pricing calibrated to your ZIP code.
The platform claims AutoMate generates estimates 2.5x faster than manual methods. The key advantage here is that estimates live inside the Houzz Pro CRM, so client management, proposal delivery, and project tracking are all connected.
Pricing: Houzz Pro for contractors starts around $249/month. AutoMate is included in the platform, not a separate add-on.
Best for: Remodelers who are already on Houzz Pro or considering it for its marketplace and CRM features. The AI estimating is a bonus, not the primary reason to choose it.
JobNimbus Scout: Field Estimating via Voice
JobNimbus Scout (released as beta in early 2026) is a mobile AI assistant for field estimating. A tech at the job site can speak or type to create estimates, jobs, contacts, tasks, and invoices directly in the JobNimbus app without touching a keyboard.
“Scout, create an estimate for a bathroom gut renovation at 123 Main Street. Demo, tile, fixtures, labor. Rough scope $18,000 to $24,000.” Done. The estimate is in the CRM before the tech walks out the door.
Best for: Roofing and home services contractors already on JobNimbus who need field estimating without office bottlenecks.
ServiceTitan AI Estimator
ServiceTitan’s photo-based AI Estimator generates tiered estimates from a photo of the job area. For HVAC, plumbing, and electrical service companies, this means a tech can snap a photo of the unit, the panel, or the fixture and get a 3-tier estimate (good, better, best) in under a minute, formatted and ready to present on the doorstep.
Best for: HVAC, plumbing, and electrical companies running ServiceTitan. The AI Estimator is included in the base subscription.
The accuracy question: should you trust AI estimates?
The honest answer is: yes, with oversight. AI handles approximately 80% of the estimation work. The remaining 20% requires a human to review flagged items, apply judgment to scope gaps, and verify quantities on complex elements the AI struggled with.
The University of Kansas study found Togal.AI maintained accuracy within 5% of manual takeoffs, with most discrepancies correctable in under 5 minutes. A February 2026 independent test of 6 AI estimating platforms showed error margins of 1.8% to 4% on complex multi-discipline projects.
The contractors winning bids in 2026 aren’t replacing estimators with AI. They’re using AI to let estimators produce 3x as many bids at the same or better accuracy, which means more shots at revenue.
What to adopt first
If you’re bidding residential remodeling, start with Handoff AI at $39/month. The entry cost is low enough that recovering a single additional job per month from faster proposal delivery pays for a year of the software.
If you’re doing plan-based commercial or trade work, Togal.AI at $299/month justifies itself quickly if you’re doing 2+ complex takeoffs per week. One hour saved per takeoff on 10 takeoffs a month is 10 hours recovered. At a fully-loaded rate, the math closes fast.
The goal isn’t to make estimates faster for the sake of speed. It’s to submit more bids with the same team, which is the only way to grow revenue without hiring.
