Pay as you go, or $397 a seat a month, billed annually.

The AI takeoff of each plan sheet, and the AI you run later, such as Auto Measure re-runs, chat answers, symbol search, AI estimates and schedule reads. Uploading (every sheet named and scaled), measuring by hand, exports and e-sign use none. Bigger AI actions ask first, showing the credits they use and your balance. On Pro, nothing uses credits.

An electrical plan or a floor plan: the sheets the AI takeoff counts and measures. Each plan sheet's AI takeoff uses credits. Every other sheet in the set (covers, details, schedules, notes, specs) is named and scaled free.

No. Payment details only come in when you buy credits or pick Pro.

Two ways. Pay as you go: your workspace buys credits through Stripe when it needs them, and the AI spends them as you use it. Nothing renews. Or Pro, for unlimited projects and all AI with no credits, priced per seat. A seat is one person: everyone who signs in to your workspace uses one, and so does an invitation nobody has accepted yet. Pro is $397 a seat per month, billed annually ($4,764 a seat for the year). Adding a seat mid-year charges the prorated rest of the year right away; removing one takes effect at renewal. You can cancel renewal any time from billing settings.

Uploading. Every sheet in the set comes back named and scaled, so you can see what's there. The AI takeoff runs once you buy credits or pick Pro.

No. Credits sit in one balance for your workspace, work on every project in it, and never expire.

Add sheets or upload a revision and the AI takeoff uses credits for the new sheets only. Sheets already taken off aren't charged again. On Pro, they're covered like every other sheet.

We don't quote an accuracy percentage; no single number survives a different office's drawings. Instead, every detection carries a confidence level, and anything the AI isn't sure about is flagged with a red dashed outline for review. You check what needs checking instead of silently re-checking everything.

Yes, as one workspace: everyone signs in as themselves and works on the same projects. Credits belong to the workspace, not to a person: one balance, usable on every project. On Pro, you buy one seat for each person.

PDF plan sets. Multi-page sets are supported, and pages are classified by trade automatically.

Bildrix is built for US and Canadian construction projects. It reads plan sets in imperial or metric units and can display quantities in metric and amounts in Canadian dollars in the app. The subscription is billed in USD; electrical references follow NEC or CEC conventions by job site (Québec's Chapitre V included). 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.
