Yes for the geometry, not for the drywall. AI takeoff tools such as Kreo and BuildVision measure rooms, walls and openings from PDFs, but sheets, compound and labour still come from your own assemblies and waste rules. At about $2,100 to $3,600 a year, they pay back only above roughly 30 to 55 bids on the sums below.
Photos are a separate route. A LiDAR scan or a tape measure gives room sizes when no drawings exist, and Apple describes its own Measure results as approximate. Neither a photo nor a scan shows wall height, board type or finish level, so a scan job still needs a short site note before the sheet means anything.
What each tool counts from a PDF, and what it leaves to you
These are the pages the vendors publish, read in October 2026. Accuracy figures are the vendors' own claims; Kreo describes its test set in general terms, and none of the pages gives a sample size.
| Tool | What it counts or measures, per its page | List price | Trial | What the page doesn't say |
|---|---|---|---|---|
| Kreo | Auto Measure returns rooms with areas, walls with lengths and thicknesses, finish surfaces, and door and window counts from PDF, CAD or image files; its drywall page lists calculators for panels, studs, headers and insulation | Pro $175 per user a month, billed yearly ($2,100); Essential at $100 is sold as 'without AI' | 7 days on each paid plan | Whether the drywall calculators use AI; its 94% outline-accuracy figure for Auto Measure 3.0 (switched on by request) comes from Kreo's own set of dense plans, with no sample size |
| BuildVision AI | Symbols, counts and linear runs, with confidence scores and review flags on each takeoff; drywall is on the pricing page's trade list, but not on the home page's list of pre-trained models, which offers fine-tuning on your drawings for unlisted trades | Pro $299 a month, up to five users ($2,990 a year billed yearly); Max $599 | 14 days with 50,000 AI tokens; a card is required | Takeoffs per month: usage is metered at 500 tokens a page and 20 a detection. Its home page describes no drywall-specific measures |
| Togal.AI | Detects, measures and compares from drawings of any file type; links a drywall page | No prices on the home page | None stated; demo and self-guided tour | What its drywall coverage includes; 'up to 98% accuracy on floor plans' is a claim only |
| iBeam (its pages now say Beam AI) | Done-for-you drywall takeoffs from PDF plans, specs and legends in 24 to 72 hours, with a human QA review | Done-for-you licences from $25,000 a year; the cheaper do-it-yourself licence isn't offered for drywall | Guided tour and demo | An error rate: its home page says '99%+ accurate', its drywall page gives none |
| Polycam (scan route) | Space captures, using LiDAR on compatible iOS devices, and a ruler measurement on Basic; floor area, interior and automated measurements and editable 2D floor plans need Business; Basic exports include PDF, PNG, SVG, CSV and CAD DXF per its FAQ | Basic $150 a year or $30 a month; Business $400 a user a year; a free plan is limited | Free plan | Measurement accuracy, and any estimate of board: it measures space, not material |
The common thread is geometry. They measure rooms, walls and openings, or count symbols. The step from 1,564 square feet of net wall to sheets, compound pails and labour hours uses your assemblies and waste rules, and of the pages read only iBeam's service, Kreo's calculators and BuildVision's assembly libraries (which hold your own material costs and labour rates) describe that step at all. So the output of any tool here is an input to your sheet, not a finished estimate. Six AI takeoff tools for contractors, matched to trade and plan type compares more of the field if these five don't fit.
Plan takeoff or photo scan: what the job calls for
The question is less about which technology is better than which inputs the job gives you.
| Job | Drawings exist? | Route | Why |
|---|---|---|---|
| Tenant fit-out from an architect's set | Yes, with a wall-type legend | Plan takeoff, by hand or AI | Drawings carry board type, fire ratings and heights that no photo shows |
| New home from a builder's PDF set | Yes | Plan takeoff; confirm ceiling heights room by room | The tool measures; the finish schedule decides board and height |
| Basement finish for a homeowner | No | Tape or LiDAR scan, plus a site note | There is nothing to take off, so you measure the space |
| Remodel from a sketch | Sketch only | Scan or tape, checked against the sketch | Sketches drift; confirm lengths and openings |
| Repairs and patches | No | Neither; price by the visit or hour | A takeoff costs more than it saves |
A photo can't give you three things a drywall bid depends on: the height of the wall, the board type and thickness, and the finish level. For a scan job, write those into a one-line site note per room before you leave: 'Rec room, 8 ft, standard 1/2 inch, level 4'. A scan needs a compatible phone or tablet, and Polycam's FAQ says its space scanning works only on compatible iOS devices. Apple describes Measure results as approximate and best on well-defined objects 2 to 10 feet from the phone, so check a few walls with a tape even on scanned jobs. If you quote repairs or painting from photos, how painters and decorators quote from photos with AI shows where that approach works and where it stops.
Check a scan the way you would check a tool, with a tape on three measurements before you rely on it. Illustrative results for a scanned basement:
| Measurement | Tape | Scan | Difference |
|---|---|---|---|
| Rec room long wall | 18 ft 1 in (217 in) | 18 ft 0 in (216 in) | -0.5% |
| Bedroom short wall | 11 ft 2 in (134 in) | 11 ft 5 in (137 in) | +2.2% |
| Utility ceiling height | 7 ft 11 in (95 in) | 8 ft 0 in (96 in) | +1.1% |
Set a pass mark of 1% on lengths and 1 inch on heights before you scan. The bedroom wall fails: 3 inches over on 11 ft 2 in. Re-scan it, and look at what was in the way, since furniture, glass and mirrors are the usual suspects when a scan drifts. The ceiling height is within an inch, but heights deserve their own check because they multiply through every wall. An inch on an 8 ft ceiling is about 1.0% of the wall area, or roughly 18 square feet of the 1,696 on the basement job in the next section.
A basement finish from room sizes to sheets, pails and labour
Here is a job to run through the sheet, with every figure illustrative: five rooms in a basement, 8 ft ceilings, measured by tape.
| Room | Size | Perimeter | Gross wall | Openings | Net wall | Ceiling |
|---|---|---|---|---|---|---|
| Rec room | 18 x 14 ft | 64 ft | 512 sq ft | 2 doors, 40 sq ft | 472 sq ft | 252 sq ft |
| Bedroom | 12 x 11 ft | 46 ft | 368 sq ft | 1 door, 1 window, 32 sq ft | 336 sq ft | 132 sq ft |
| Bathroom | 8 x 7 ft | 30 ft | 240 sq ft | 1 door, 20 sq ft | 220 sq ft | 56 sq ft |
| Utility | 10 x 8 ft | 36 ft | 288 sq ft | 1 door, 20 sq ft | 268 sq ft | 80 sq ft |
| Hall | 14 x 4 ft | 36 ft | 288 sq ft | 1 door, 20 sq ft | 268 sq ft | 56 sq ft |
| Total | 1,696 sq ft | 132 sq ft | 1,564 sq ft | 576 sq ft |
Doors are 3 ft by 6 ft 8 in, about 20 square feet, and the window is 3 by 4 ft. Some crews don't deduct small openings because cut-outs add labour and waste, so a good sheet has a switch for it. Here every opening is deducted.
Board. Net wall plus ceiling is 1,564 plus 576, or 2,140 square feet. The bathroom takes moisture-resistant board: walls 220 plus ceiling 56 is 276 square feet. That leaves 1,864 square feet of standard board. With a 10% waste allowance, a starting assumption to replace with your own history, standard board is 2,050 square feet and moisture-resistant is 304. A 4 x 8 ft sheet covers 32 square feet, so that is 64.1 and 9.5 sheets, rounded up to 65 and 10: 75 sheets in total.
Calibrating the waste. The 10% is a placeholder. Your own jobs give a better figure: add up the net board area on the last ten completed jobs and the sheets you bought for them. If the last ten jobs had 21,400 square feet of net area and you bought 742 sheets, that is 742 times 32, or 23,744 square feet, so the waste was 2,344 square feet, or 11.0%. Use 11% and keep the record going, because waste differs between a basement with short runs and a tenant fit-out with long ones.
Compound. USG's FAQ for one of its ready-mix compounds says to expect about two 4.5-gallon pails to finish 1,000 square feet of wallboard, without stating the finish level or number of coats. On 2,140 square feet that is 4.28 pails, so five. Listings for other compounds quote different coverage per pail, so replace the 2 per 1,000 with your crew's own record from the last ten jobs.
Labour. At assumed crew rates of $0.80 a square foot to hang and $1.10 to tape and finish, $1.90 in total, the 2,140 square feet come to $4,066. The boards at an assumed $15 a sheet add $1,125 for 75 sheets. Before compound, fasteners, bead, overhead and margin, the job stands at $5,191. The point of the exercise isn't the price; it's that every line above was a number you could check against a hand measurement, which the next section does.
Three accuracy checks before you trust a takeoff
Check one: a known dimension. Find something on the plan with a printed size, such as a door marked 3'-0", and measure it with the tool. If the tool reads 3.09 ft, that is a 3.0% error in length, and areas scale with the square of length: 1.03 squared is 1.0609, so a 6.1% error in area. On 2,140 square feet of board that is about 130 square feet, four sheets, and at $1.90 a foot of labour plus $15 a sheet it's about $307 on one bid. If the error is in the scale setting, it repeats on every room, which is why this is the first check. A plan that was printed to PDF at a different sheet size from the original makes its stated scale, such as a quarter inch to the foot, wrong, so no stated scale should be trusted until a known dimension confirms it.
Check two: three rooms against a hand measure. Measure three rooms by hand from the dimension strings, and compare with the tool's net wall area. Illustrative results:
| Room | By hand, net wall | Tool | Difference |
|---|---|---|---|
| Rec room | 472 sq ft | 486 sq ft | +3.0% |
| Bedroom | 336 sq ft | 329 sq ft | -2.1% |
| Bathroom | 220 sq ft | 249 sq ft | +13.2% |
| Total | 1,028 sq ft | 1,064 sq ft | +3.5% |
Set pass marks before you look: each room within 5% and the total within 3%. This run fails both. The bathroom is 29 square feet high, which is one face of a partition about 3 ft 7 in long at 8 ft: the short wall at the end of a tub alcove. A likely cause is that the tool measured that face like any other wall, while the hand measure, taken from the room's perimeter, never included it. Tiled on backer board, it doesn't belong in the drywall total either way. The fix is a rule on the sheet that wet-area walls come out of the drywall total, and a question for the vendor about how its tool treats tiled walls. The rec room and bedroom are fine, so the fault is not the scale.
Check three: a ratio from your own past jobs. This job has 1,564 square feet of net wall on 576 square feet of floor, 2.7 to 1, and 2,140 square feet of board in all. Look at the same ratio on your last ten completed jobs. If a tool returns 4.5 to 1 on a basement, something has probably been counted twice. The ratio won't prove a takeoff right, but it catches the big errors in seconds, and a crew that keeps the numbers from each finished job gets better at spotting them.
The free baseline: a spreadsheet, with ChatGPT writing the formulas
Before paying for anything, build the sheet above in a spreadsheet and let ChatGPT write it. The files ChatGPT reads, the limits and what breaks are covered in can ChatGPT read PDFs, spreadsheets and photos. What matters for a takeoff is that it is a language model, not a measuring tool, so you type the dimensions and it writes the formulas. A prompt that works:
Build a drywall takeoff sheet for a spreadsheet. I will type the room list
with length, width, ceiling height, number of doors and windows, and a column
saying whether the room takes standard or moisture-resistant board.
For each room calculate: perimeter, gross wall area, openings deducted
(doors 20 sq ft each, windows as typed), net wall area, ceiling area.
Totals: board area by type, sheets of 4 x 8 ft with a waste percentage I can
change (start at 10%), rounded up once on the total not per room, and joint
compound pails at a rate per 1,000 sq ft that I can change (start at 2).
Give me the formula for every calculated cell. Do not estimate any dimension
I have not typed in.A realistic first answer gets the structure right but writes the net wall total as 1,584 instead of 1,564, because it added the five rooms in its head instead of with a SUM formula. That is a 20 square foot slip, only $38 of labour here, but the same habit on a larger job costs more. The fix is to ask for formulas only and let the spreadsheet add. Then test the finished sheet on one job you've already worked out by hand, which is what the table above is for. Ask for the waste to be applied once to the total and rounded up once, because rounding up each room's sheets separately adds a sheet on this job: 76 instead of 75.
What a small crew pays, and how many bids it takes to break even
The software fee only matters against the hours it saves. These sums use two assumptions you should replace with your own: an estimator's time is worth $45 an hour, and the tool plus its checks saves 1.5 hours a bid, say from 2.5 hours by hand to one hour. That is $67.50 a bid.
| Route | Yearly cost, list | Bids to break even | Net at 40 bids a year |
|---|---|---|---|
| Spreadsheet and PDF viewer, by hand | $0 in software | Not applicable | Baseline |
| Kreo Pro, one user | $2,100 | About 31 | $2,700 saved less $2,100, so +$600 |
| BuildVision Pro | $3,588 paid monthly; $2,990 billed yearly | About 53, or 44 billed yearly | $2,700 less $3,588, so -$888 (-$290 billed yearly) |
| iBeam done-for-you | From $25,000 | About 370 | $2,700 less $25,000, so -$22,300 |
| Polycam, scan route | $150 for Basic, or $400 a user for Business's room measurements, plus a LiDAR-equipped device | Not applicable | Saves tape time on remodels; it doesn't estimate board |
On those assumptions a crew bidding 40 jobs a year makes a small gain with one per-user tool, loses a little with a pricier one and cannot justify a done-for-you licence on time saved alone. Two things change the sums. A tool that lets you bid more jobs, instead of only bidding faster, changes the value: if an extra job a year earns $4,500 in gross profit, a $2,100 plan is covered twice. And a tool that is per user doubles when a second estimator joins. During any trial, time three real bids by hand and by tool and replace the 1.5 hours. BuildVision's meter gives a rough idea of capacity. Its own example puts a 50-page set with 1,000 detections at about 45,000 tokens, close to all of Pro's 50,000 a month. A 12-page house set with 300 detections would use about 12,000 (6,000 for the pages, 6,000 for the detections), so roughly four such sets a month before you buy extra tokens at its usage rate.
Check that last claim on the vendor's trial, because token use depends on how many detections you run. The wider price bands, with and without AI, are in how much estimating software costs a small contractor.
What to ask a vendor to run on two of your old bids
- Run a bid you've already won and one you lost, so you know the right answer. Compare net wall, ceiling and opening counts with your sheet before you look at anything else.
- Show how the tool treats wet-area walls, bulkheads, soffits and curved or angled walls, which are where hand estimators and AI both slip.
- Show how it reads the wall-type legend: does a fire-rated partition end up in the Type X total?
- Export the measurements to a spreadsheet and show that the numbers match the screen.
- Ask what it does when it is unsure: a confidence score, a review flag, or a silent guess.
- Ask for the price at your volume, including seats and any token or takeoff limits, in writing.
The method for pricing the result is in how to price drywall jobs per sheet and per square foot with AI, and plan review and scope checks for drywall bids covers what a takeoff can't see: exclusions, finish levels and access.
When to stay with a tape and a sheet
If you bid fewer than 30 jobs a year, most of your work is remodels with no drawings, or your jobs are mostly repairs, the software has little to measure. A sheet you trust, a PDF viewer for the plans and a habit of checking three rooms by hand on every bid beat a tool you can't verify. If you'd rather test the two routes on your own bids with someone, that is what my AI implementation consultation covers: finding the jobs where AI pays off, adding AI to the tools you already use, and handing over something the crew can run. The contact page has the form.
Questions drywall crews ask about AI takeoff
Can ChatGPT take off drywall from a plan?
It can read the text on a drawing and build the sheet, but it isn't a measuring tool. Give it dimensions you have confirmed, ask for formulas rather than totals, and test it first on a room you have measured by hand. Treat any area it reports from the image alone as a guess until a known dimension on the plan checks out.
How accurate are AI drywall takeoff tools?
Vendors make claims, not guarantees: Kreo reports 94% outline accuracy for its latest Auto Measure model on its own set of dense plans, Togal.AI says up to 98% on floor plans, and iBeam says 99%+ with human review. None of the pages read for this tutorial gives a sample size, so run your own check on two past bids before paying.
Is a LiDAR or photo scan accurate enough for a quote?
It's good for room sizes if you check a few walls with a tape. Apple calls its own Measure results approximate and best on objects 2 to 10 feet away, and a scan can't tell you board type, finish level or what is behind the wall. Use it where no drawings exist, and add a site note for everything a scan misses.
How many bids a year before AI takeoff software pays?
On the sums here, assuming it saves 1.5 hours a bid at $45 an hour, Kreo's $2,100 Pro plan needs about 31 bids a year and BuildVision's Pro plan about 53 paid monthly ($3,588) or 44 billed yearly ($2,990). Time one real bid by hand and by tool during the trial, because the saving is an assumption until you measure it.
Should a small crew use a done-for-you takeoff service?
Rarely. iBeam's drywall service starts at a $25,000 annual licence, which is $625 a bid at 40 bids a year before any labour is saved. It suits firms bidding in volume. A crew of three to six is usually better served by a spreadsheet, a PDF viewer and, if the sums work, a per-user tool.
