How we make this list: we compare pricing pages, product documentation and public user reviews. Rankite is independent; if a vendor ever pays for a featured spot, that listing is clearly labeled Partner.
Key takeaways
- AI takeoff is the 2026 breakthrough: Togal auto-detects and measures from drawings at up to 98 percent accuracy, and STACK's AI reads plan sheets, auto-counts symbols, and flags revisions.
- The category split in two: AI takeoff tools for estimators doing plan-based bids (Togal, STACK, ProEst) versus AI-assisted estimating for residential contractors (Buildxact's Blu, Bolster, Clear Estimates, Joist).
- CostCertified rebranded to Bolster in 2026, expanding from estimating into full construction management with automated scheduling and payments.
- Pricing is mostly quote-based; only the residential tools publish trial terms, so expect a demo-driven buying process for the enterprise options.

The best ai estimating software
#1
Togal.AI
Best for: AI takeoff from drawings for estimators
Visit togal.ai
Starting priceSee website
Free planNo
Togal.AI is the purest AI play in construction estimating. Built by estimators, it automatically detects, measures, and compares quantities directly from drawings, claiming up to 98 percent accuracy on floor plans and takeoffs five times faster than manual methods. The 2026 platform adds Togal.CHAT, which lets you literally talk to your construction plans.
The workflow is built for estimating teams: upload any drawing file type, let the AI measure, compare drawing sets with one click to quantify changes, and collaborate in the cloud in real time. Testimonials from firms like SR Construction and DPR Construction emphasize the time savings on every project.
The honest catch is scope. Togal is a takeoff tool, not a full estimating and project management suite; you will pair it with estimating software for pricing and proposals. Pricing also requires a conversation. For estimators drowning in plan takeoffs, it is the most direct AI productivity win here.
What we like- AI auto-detects and measures directly from drawings at up to 98 percent accuracy
- Takeoffs run 5 times faster
- Cloud collaboration with Togal.CHAT to talk to plans
Watch out for- Takeoff-focused rather than a full estimating suite
- Pricing is quote-based with no public numbers

STACK rebranded itself as the AI preconstruction platform, and the 2026 workflow shows why. Upload plans and the AI reads every sheet, auto-names pages, and flags revisions. Takeoff measures linear, area, count, and volume with AI auto-counting symbols and suggesting missed scope. Quantities flow into live estimates where AI pressure-tests pricing, and the same data carries into the field for RFIs and daily reports.
The breadth is the pitch: evaluate, takeoff, estimate, and build in one cloud platform, with regional cost data integration, trade-specific item libraries, and a mobile jobsite app. Thousands of contractors, suppliers, and owners use it across trades from concrete to roofing.
The trade-off is that STACK is a platform commitment with quote-based pricing, and solo contractors will find it heavy. For estimating teams that want AI across the whole preconstruction workflow rather than a point tool, STACK is the most complete option.
What we like- End-to-end AI from plan evaluation to field build
- AI auto-counts symbols and pressure-tests pricing
- 100 percent cloud-based with unlimited viewer seats
Watch out for- Quote-based pricing
- The full platform is more than small contractors need

ProEst is the established cloud estimating suite for general contractors, subcontractors, and civil contractors. The platform covers digital takeoffs, cost databases, bid management, bid analysis, proposals, document management, and a construction CRM, with integrations to Procore, Autodesk Build, Sage Intacct, QuickBooks, and more.
The standout is the pricing model: your annual subscription is based on awarded jobs using ProEst, so you pay only for the jobs you win. That built-in flexibility is unique in the category and aligns the vendor's incentives with yours. Case studies claim doubled estimating output and major bidding efficiency gains.
The honest catch is the buying process. Pricing requires a sales conversation, and implementing a full estimating suite takes weeks of configuration and training. ProEst is less about AI flash and more about institutional estimating discipline. For established contractors standardizing estimating across teams, it remains the reference choice.
What we like- Comprehensive estimating with takeoffs, bid management, and CRM
- Unique pay-only-for-jobs-you-win pricing model
- Deep integrations with Procore, Autodesk, and accounting tools
Watch out for- Enterprise sales process with no public pricing
- Implementation takes real effort

Buildxact is total job management for residential builders, and its 2026 headline is Blu, an AI building assistant trained on thousands of residential projects. Blu's toolbelt includes an Assembly Assistant for repeatable jobs, an Estimate Reviewer that double-checks for mistakes, a Takeoff Assistant for fast plan measurement, and an Estimate Generator that builds complete estimates from scratch.
Beyond AI, Buildxact connects estimating to dealer pricing for live material costs, then carries the job through scheduling, project management, and invoicing. Plans scale from Foundation (estimate and bid) through Pro (job management) to Master (the full platform for larger teams).
The trade-off is focus. Buildxact is residential through and through; commercial contractors should look elsewhere. Pricing is not published, which is frustrating for a product aimed at small builders. For residential contractors wanting AI help with every estimate, Blu is the most assistant-like AI here.
What we like- AI assistant Blu reviews estimates, assists takeoffs, and generates estimates from scratch
- Dealer connection with live material pricing
- Plans from Foundation to Master
Watch out for- Residential-focused, not built for commercial
- No public pricing on the plans

Bolster, formerly CostCertified, is the 2026 rebrand of the Y Combinator-backed estimating platform, now positioned as full construction management software. The pitch is Construction Intelligence: estimate with live AutoCost pricing, then let budgets, schedules, and material lists generate automatically from the estimate, with progress payments and QuickBooks sync.
The distinctive feature is customer self-service: pre-set upgrades, options, and selections let customers re-estimate themselves, upgrading without awkward phone calls. Revisions trigger automatic change orders with new approvals, killing scope creep. Users report 5x estimating speed and doubled win rates.
The honest catch is the rebrand transition. Search results and reviews still reference CostCertified, which can confuse buyers. Pricing requires a demo. For residential remodelers and custom home builders who want estimating to flow into project management automatically, Bolster is the most automation-forward option.
What we like- Construction Intelligence automates estimating, scheduling, and payments
- Customer self-service upgrades and selections boost margins
- Y Combinator-backed with strong reviews
Watch out for- Rebranded from CostCertified, so reviews and recognition are split across names
- Pricing is quote-based

Clear Estimates is the straightforward choice for residential contractors who want accurate numbers fast. The core asset is its cost database: over 12,000 parts with localized material and labor pricing across 400-plus US areas, updated quarterly. That is the same data family trusted by Remodeling Magazine's Cost vs. Value Report.
The workflow is template-driven: pick from 500-plus project templates for kitchens, bathrooms, decks, siding, and more, enter dimensions, and get an itemized estimate with local rates. Pre-written contract language turns estimates into professional, branded PDF proposals in seconds. A 30-day risk-free trial lets you test on real jobs.
The trade-off is AI and scope. Clear Estimates is a cost-data calculator, not an AI takeoff tool; it will not read your drawings. It is also residential-only. For remodelers and specialty contractors who know their quantities and need trustworthy local pricing, it is the fastest path to a professional bid.
What we like- 12,000-part cost database localized to 400-plus US areas
- 500-plus project templates
- 30-day risk-free trial
Watch out for- Residential-only with no commercial support
- Less AI than the category leaders

Joist
Best for: simple contractor estimates and invoicing
Visit joist.com
Starting priceSee website
Free planFree trial
Joist is the simple app for contractors who want estimates, invoices, and payments without learning construction software. Create professional estimates from templates, convert to invoices in one click, accept cards, bank transfer, and PayPal, and manage jobs and schedules, all from the jobsite. Over 1.3 million contractors use it.
The 2026 addition is the Joist AI Receptionist, which answers calls you cannot get to, captures job leads, and speeds follow-up. Homeowner financing from 30-plus lenders can be offered right on estimates. The 14-day free trial with instant signup makes testing painless.
The honest catch is depth. Joist does not do plan takeoffs, cost databases, or bid management; it is an estimating and invoicing app, not an estimating department. For small contractors, handymen, and specialty trades who need professional quotes fast, it is the easiest win on this list.
What we like- 14-day free trial with no credit card
- 4.9-star ratings across 12,000-plus reviews
- AI Receptionist answers missed calls and captures leads
Watch out for- Estimating depth is basic compared to takeoff tools
- Payment processing and financing carry their own fees
How we chose
We compared AI estimating tools serving US contractors in 2026, using current vendor homepages and product announcements. We weighted genuine AI capability (takeoff automation, AI assistants, intelligent pricing) over marketing claims, breadth from takeoff to payment, trade and project-type fit, pricing transparency, and review reputation. We included both AI-first tools and established platforms adding AI. We did not claim hands-on testing; all facts come from vendor-published material.
What to check before you buy
Separate takeoff from estimating in your evaluation. AI takeoff tools (Togal, STACK) save time measuring plans; estimating platforms (ProEst, Buildxact, Bolster) price and manage the job. Many contractors need both, and they integrate.
Run a real plan through the trial
Every AI vendor demos on clean plans. During any trial, upload your messiest recent drawing set: scanned PDFs, revisions, unclear scales. The AI that handles your real plans accurately is the one worth paying for; accuracy claims mean nothing until tested on your work.
Price the whole workflow
Quote-based pricing hides the total. Ask about per-user fees, plan tiers, transaction costs, onboarding charges, and what the AI features cost at your usage level. ProEst's pay-for-awarded-jobs model and Clear Estimates' flat approach are the exceptions; budget for discovery.
Check the handoff to the field
An estimate that dies in the office is half a tool. Verify how quantities, budgets, and schedules flow to project management and accounting: STACK carries data to the field natively, Bolster generates schedules from estimates, and ProEst integrates with Procore and accounting systems.
AI is eating the takeoff first
The clear 2026 pattern is that AI conquers measurement before pricing. Auto-detecting quantities from drawings is a contained problem that AI solves well, which is why Togal and STACK lead with it. Pricing judgment, with its local labor quirks and strategic markups, stays human longer. The winning setup for most contractors is AI takeoff plus human pricing, and every tool here is racing to deliver exactly that.
Frequently asked questions
What is the best AI estimating software for contractors?
It depends on the work. Togal.AI leads for AI takeoff from plans, STACK for end-to-end AI preconstruction, Buildxact for residential builders wanting an AI assistant, and Joist for simple contractor estimates. Match the tool to whether you bid from drawings or from site visits.
How accurate is AI takeoff?
Togal claims up to 98 percent accuracy on floor plans, and users report major time savings. Real-world accuracy depends on drawing quality; always verify AI measurements on your own plans during a trial before trusting them on bids.
How much does AI estimating software cost?
Most enterprise tools quote custom pricing. Residential tools are more transparent: Clear Estimates offers a 30-day trial and Joist a 14-day trial, both with published plan structures. Expect per-user or per-project pricing to emerge during demos.
Can AI estimating software replace an estimator?
No. AI handles measurement and drafting far faster than humans, but pricing strategy, scope judgment, and client relationships remain human work. The realistic gain is an estimator producing several times more bids, not eliminating the role.
What happened to CostCertified?
CostCertified rebranded to Bolster, expanding from estimating into full construction management software with automated scheduling, payments, and project management. The website remains at costcertified.com during the transition.
Do I need both takeoff software and estimating software?
Many contractors use both: an AI takeoff tool like Togal to measure plans, feeding quantities into an estimating platform like ProEst or Buildxact for pricing and proposals. STACK and Bolster combine both in one platform.
