AI takeoff software that shows its doubt.
Bildrix reads your PDF plan set, counts and measures what’s drawn (rooms, doors, windows, walls, electrical devices, wire runs) and flags what it isn’t sure about instead of hiding it. The quantities carry into the estimate, the signed change order and the invoice.
With your review call · PDF plan sets
One upload. The first pass runs trade by trade.
Architectural quantities are detected at upload: rooms, doors, windows and walls, named from the drawing's own labels and measured in SF, EA and LF. Detect All then runs the remaining trades across the set: electrical devices counted against the sheet's own legend, wire runs drawn or AI-suggested, plumbing fixture counts when you ask.
Automated takeoff, reviewed before it's trusted.
Every detection carries a confidence level. Sure things render solid; uncertain ones are flagged and queued for review, where you accept, reject or reshape them in the canvas, wire routes included. Anything the AI misses, you count or draw in the same takeoff. We publish no accuracy percentage; the flags are the honest version of that number.
Takeoff that doesn't stop at quantities.
Counts become a priced estimate with per-line provenance: library price, AI-estimated price, AI-estimated quantity. Your client signs a sealed, revision-bound proposal. When the drawings change, revision compare stages the difference as a change order in AIA G701 format, reductions as credits. Invoices (deposit, progress, final, retainage) go out with online payment and CSVs shaped for QuickBooks import.
What happens to your documents.
Bid sets are competitively sensitive. Said plainly.
Your plan sets stay in your workspace, stored on Cloudflare R2. Remove a project from your workspace whenever you choose.
Detection runs through enterprise AI APIs under terms that exclude training on your data. Your plans never train AI models.
Client view structurally hides cost and margin columns. The shared page and PDF render from it, so margin can't leak.
The signed PDF is rendered once at signing, sealed and SHA-256 fingerprinted, bound to the exact revision signed. Every later download serves those same bytes.
No SOC 2 audit yet. We're a small team and we'd rather say so than imply one. Ask us anything about data handling at support@bildrix.com.
Six questions to ask any AI takeoff tool, and our answers.
Most AI takeoff products demo well on a curated plan set. The differences show up in daily use, so ask the questions a demo can gloss over.
Does it show what it isn't sure about?
Bildrix does: every detection carries a confidence level, and the uncertain ones are flagged and queued for review. You verify the flagged minority, not the whole sheet.
Can you edit the AI's output where it lives?
Yes. Counts, boundaries and wire routes are editable in the canvas. A wrong count is two clicks, not an export to Excel.
Does the takeoff carry into the estimate, change order and invoice?
It does, in one thread. Nothing is re-typed, and every number stays traceable to the drawing it came from.
Is the price published?
Yes. One flat plan for the whole workspace, up to five teammates included, billed annually. The figures and what's included are on the pricing page, no demo call required. Published pricing, no demo gate →
Are the trades stated plainly?
Architectural quantities and electrical takeoff in depth; plumbing fixture counts on demand. Nothing else is claimed. Electrical takeoff, in depth →
Does it read the drawings you actually receive?
PDF plan sets, vector or scanned. Messy scans and sparse sheets are labeled honestly rather than reported as confident zeros. Not CAD files, not phone photos.
The trades this AI takeoff software covers today.
Depth is stated per trade, not implied. If it isn’t listed here, Bildrix doesn’t take it off yet.
Rooms, doors, windows, walls
Detected at upload, named from the drawing's own labels, measured in SF, EA, and LF, and priced through your assembly library.
The deepest trade
Legends read, devices counted, wire runs drawn or AI-suggested with live footage, panel schedules read into an editable Panel Editor, circuits grouped. Devices and wire get their own ledger.
Fixture counts, on demand
Fixture detection runs when you ask: one button, or part of Detect All. Counts land in the takeoff like any other quantity.
Built for the 1 to 15 person electrical sub.
Plan-set commercial and TI work. If that's you, this was built around your Tuesday. Small GCs running plan-set jobs fit too. Built for US and Canadian projects: USD pricing, NEC references, imperial units.
Now onboarding founding partners.
Small estimating teams, residential GCs, and electrical contractors first. Your first takeoff is free, with your review call. Founding-cohort pricing is on the pricing sheet.
The questions estimators actually ask.
Is Bildrix automated takeoff software or AI-assisted?
Both words get used for the same thing, so here is what actually happens. The first pass is automated: the AI reads the sheets and counts and measures what's drawn. The review is yours: uncertain detections are flagged and queued, and you accept, reject or reshape them before a number reaches the bid. We call that review-first: automated where the drawing is clear, flagged where it isn't.
Is there a free AI takeoff software trial?
Two doors, both free. Book the review call and send a PDF plan set. We run the takeoff and walk the results with you on your own project. Or start free in the app: the first 15 pages of AI detection run on your sheets, no credit card, and re-running a processed page is free.
What does AI takeoff software cost?
Pricing is public. Bildrix is one flat plan for the whole workspace (up to five teammates included, no per-seat charges), billed annually, and you can cancel renewal any time. The figures and what's included are on the pricing page; no demo call required. See pricing →
Which trades does the AI takeoff cover?
Architectural quantities (rooms, doors, windows, walls) and electrical takeoff (devices, wire runs, circuits, panel schedules) in depth, and plumbing fixture counts on demand. If it isn't listed on this page, Bildrix doesn't take it off yet. We'd rather say so here than after you've uploaded a set.
Does it do electrical takeoff?
Electrical is the deepest trade in Bildrix: device symbols counted against the sheet's own legend, wire runs drawn or AI-suggested with live footage and editable per run, panel schedules read after upload into a Panel Editor you correct circuit by circuit, devices linked to their circuits and homeruns grouped by panel, and devices and wire landing in their own ledger rows on the way to a division-26 estimate. How it works on electrical sheets →
How accurate is the AI takeoff?
We don't publish an accuracy percentage: no single number survives contact with a different office's drawings, and we have written up what every vendor advertises against what has actually been measured. What Bildrix does instead is show its doubt: a confidence level on every detection, the uncertain ones flagged and queued for review, and every count, boundary and wire route editable in the canvas. Advertised vs measured: the research →
What files does it read?
PDF plan sets, the format drawings are actually issued in. Vector PDFs give the AI exact line geometry; scanned sheets are read visually and labeled honestly when they're rough. It does not take CAD files or phone photos.
Where is Bildrix available?
Bildrix is built for US and Canadian construction projects. Pricing is in USD, electrical references follow NEC conventions, and measurements are imperial (feet and inches). If you're bidding work outside the US and Canada, Bildrix isn't a fit yet. We'd rather say that here than after you've uploaded a set.

The thread ends here: a sealed, revision-bound estimate your client signed. Yours starts with one plan set and a call.
