Cloud-based on-screen takeoff, untangled.

Is On-Screen Takeoff cloud based?

The confusion is understandable, because the product is named after the activity. Twenty-odd years ago the alternative to a printed set, a scale ruler and a highlighter was to do the same job on a screen, and a product that let you do exactly that called itself On-Screen Takeoff. It became the standard, the name stuck, and estimators started using it the way people say Kleenex. So today an electrical estimator saying "I do on-screen takeoff" might mean they own OST, or might just mean they stopped printing sets.

When you add "cloud" to that phrase, the two meanings pull apart. One is a specific Windows program that is not cloud-based. The other is a category in which almost everything new is.

The product and the practice, side by side

Keeping the two straight matters when you are buying, because "we need cloud-based on-screen takeoff" can be answered with a hosted copy of a desktop app, a browser tool that is still fully manual, or something that changes the job. Those are three very different purchases at three very different prices.

What cloud-based should mean in 2026

Cloud has been a marketing word for long enough that it is worth pinning down. A tool that runs on a vendor's server but still needs a Windows installer, or a remote desktop session into somebody else's PC, is cloud-hosted. It is not what most estimators are asking for. In 2026, cloud-based on-screen takeoff software should mean all of the following:

• It runs in the browser. Safari, Chrome, Edge. No installer, no plugin, no download that IT has to approve.
• It runs on any operating system. Mac, Windows, Chromebook, and it is the same product on each, not a lighter web companion beside the real Windows app.
• Updates are automatic. You never see a version number, you never reinstall, and nobody is on the old build.
• The plans live in the account, not on a machine. Two people can open the same project. When the estimator who did the takeoff is on holiday, the takeoff is still there.
• Nothing is locked to a seat. If the pricing is per user, the cloud has just moved the licence server, not the constraint.
• Ideally, it does the counting. This is the part the phrase "on-screen takeoff" does not capture, because the phrase was coined for a manual process. A cloud tool where you still click every receptacle has fixed the install problem and left the forty-hour problem alone.

The last point is the one that separates the current generation from the previous one. The move from paper to screen roughly halved takeoff time for people who got good at the tools. The move from screen to automated is a different order of change: the software produces the quantities, and the estimator's hours go into review, scope and risk instead of tracing.

A checklist for buying cloud-based on-screen takeoff software

Ten questions to put to any vendor, including us. The answers sort the market quickly.

1. Does it run fully in Safari or Chrome with nothing installed, or does "cloud" mean a hosted Windows app?
2. Is the Mac version the same product as the Windows version? Ask to see it on a Mac.
3. Where are the plan files stored, and can two people open the same project at once?
4. Are updates automatic and silent, or do you ever manage a version?
5. Is pricing per seat, per project, or per trade? What happens to cost when you add a fourth estimator?
6. Does it measure, or do you? If it is manual, how is it faster than the desktop tool you have?
7. If it is automated, does it read schedules and the spec book, or only the drawings?
8. Does every quantity come back with a confidence score and a sheet reference so you can check it?
9. What is the export: Excel, a BOQ, a link into your estimating system?
10. If you stop paying, can you still get your takeoffs out?

Two of those, six and seven, are where most "online on-screen takeoff" products quietly fail. Plenty run in a browser. Far fewer do the work.

Cloud is the delivery. Automation is the point.

Pilars answers the checklist this way. It is browser-based, so it runs on a Mac, a Windows PC or a Chromebook with nothing to install and nothing to update. Projects live in the account with unlimited users. Pricing is $100 per trade, per plan set, not per seat. That is the cloud half, and on its own it would only make Pilars a convenient manual tool.

The other half is that it does the takeoff. Upload the PDF set and it reads every sheet and the spec book together, resolves cross-sheet references and the door, window, fixture and equipment schedules, counts devices and fixtures, measures lengths, areas and volumes, traces runs, and flags code issues against IBC, NEC, IPC, IMC, ADA and NFPA. Every quantity comes back with a confidence score and the sheet it came from, in a takeoff summary you can review and export to a BOQ or Excel. The how it works page goes through each step.

On the accuracy question, the number we point to is a measurement rather than a claim: 97.5% on duplex receptacles on a real power plan, against 65 to 88% for twelve other systems, with the method written up on the benchmark page. Industry AI accuracy sits in an 85 to 98% range, which is exactly why the workflow is review-first. The software does the tracing. You still sign the number.

Where cloud tools still fall short, ours included

A fair page should say this. A browser needs a connection, and a jobsite trailer with bad signal is a worse place to run any cloud tool than a laptop with a desktop app installed. Very large scanned sets take time to upload. And a cloud tool that is manual, which describes most of them, gives you portability and sharing but not speed; if you were quick in OST, you may find a browser drawing tool slower, not faster, because the desktop application has twenty years of keyboard shortcuts behind it.

Automated tools have their own honest limit: they are not perfect, which is why the confidence score exists. A 97.5% count is not a 100% count, and the review step is not optional. What changes is that reviewing two hundred flagged quantities takes an hour, and counting them from scratch took a day.
