Why Ncored?

Construction drawings need different optimisation than scanned documents. We built Ncored specifically for that.

I’m an architect. For years I lost 20 minutes a day waiting for PDF viewers to open drawings. Ncored was built by Noir architects together with engineering teams — not as a product, but as the tool we needed for ourselves.

Frequently asked questions

Quick answers to the most important questions about Ncored.

Compatibility & devices
Does Ncored work on Apple Silicon Macs?

Yes — Ncored is built natively for Apple Silicon (M1, M2, M3, M4) and runs on every modern Mac without Rosetta translation, taking full advantage of the chip. This matters most when opening heavy construction PDFs — native execution is several times faster than emulation.

Does Ncored support Windows 10 and Windows 11?

Yes. Ncored has a full Windows build that runs on Windows 10 (64-bit) and Windows 11. It installs with a standard .exe installer — no dependencies or extra components required.

Is there an iOS or Android version?

Mobile versions for iOS and Android are in the works. Today Ncored runs on desktop only (macOS and Windows), because our speed architecture depends on the full graphics power of a computer.

Does Ncored work offline?

Yes. Ncored processes every drawing locally on your computer. An internet connection is only needed for activation and updates — not for daily work on site, on the job, or while travelling.

What file sizes does Ncored handle?

Ncored is built for heavy AEC drawings. 200 MB+ construction PDFs with dozens of layers and thousands of vector objects typically first paint in about 0.8 seconds on an M4 Pro MacBook Pro. Actual speed depends on your hardware and file complexity.

Features & usage
Can I mark up and annotate drawings?

Yes. Ncored includes a full markup toolkit — freehand drawing, highlights, text notes, shapes, arrows, colours. Every annotation is saved in standard PDF format, so other tools (Acrobat, Bluebeam, Preview) can see them too.

Can I compress or flatten PDFs?

Yes. You can compress a PDF at three levels (from light to maximum) and convert it to a JPEG-based PDF with a chosen resolution from 100 to 600 DPI. Useful when shrinking a 200 MB file for email, or when sending a client a neutral-format version.

Can Ncored search text inside drawings?

Yes. Ctrl+F (Cmd+F on Mac) opens search that highlights every title, note and dimension in the document in real time — even in multi-hundred page project sets. Search runs locally, with no internet needed.

Does Ncored open ArchiCAD, Revit and AutoCAD PDFs?

Yes. Ncored is specifically optimised for PDFs exported from ArchiCAD, Revit, AutoCAD, Vectorworks and similar CAD tools. It supports layers, OCG grouping, and vector elements at full rendering quality.

Can I print from Ncored?

Yes. Ncored has a built-in print dialog with automatic page size fitting (A4, A3, A2, A1, A0, Letter, Legal, and custom). It supports duplex printing, page ranges, and scale.

How does Ncored compare to Adobe Acrobat or Bluebeam Revu?

Adobe Acrobat® is excellent for documents and signatures. Bluebeam Revu® is a well-known AEC collaboration tool (Studio Sessions, RFIs, punch lists). Ncored is built for one specific moment: the second after you double-click a heavy drawing — so it opens instantly. It’s not a universal PDF suite; it’s the daily fast viewer for architects, engineers and construction managers.

Pricing & billing
Do I need a credit card to start the trial?

No. The 14-day trial starts with just your email — payment details are only requested if you choose to continue. If the trial doesn’t fit, no subscription auto-starts.

Are all prices VAT-inclusive?

Yes. Every price shown on this site — €8.99/month, €79.99/year — already includes EU VAT. No hidden fees at checkout.

What payment methods do you accept?

Payments are handled by Paddle — all major credit cards (Visa, Mastercard, Amex), Apple Pay, Google Pay and PayPal are accepted. VAT invoices are downloadable from your Ncored account.

What happens if I cancel my subscription?

Your access stays active until the end of your paid period — after that, the subscription simply stops renewing. No surprise charges or hidden fees. Refunds for the unused portion are governed by Paddle’s buyer terms; new purchases are also covered by our 14-day money-back guarantee.

Can I get a VAT invoice for my company?

Yes. At checkout, enter your company name and VAT number — Paddle automatically generates a VAT invoice and emails it to you. All past invoices are downloadable from your Ncored account.

Teams & licensing
Can I use Ncored on more than one computer?

An individual licence is for one user and covers up to 2 devices (for example, your office desktop and your laptop on site). A team licence covers multiple users in one organisation with a single invoice.

How does team licensing work?

A team admin invites members by email from a single management panel. Seats can scale up or down at any time — billing is prorated to what you actually use. One invoice for the whole studio.

Can I switch from individual to team plan?

Yes. In your Ncored account, click ‘Upgrade to team’ to convert your individual licence into a team one — new members just accept an email invite.

What happens if someone leaves the team?

The admin removes the member from the management panel — the seat immediately becomes free and can be reassigned. If you want to drop the seat entirely, the next billing cycle is prorated automatically.

Security & privacy
Are my drawings uploaded anywhere?

No. Ncored processes every file locally on your machine. Your drawings never leave your device, are not sent to Ncored servers, and are not stored in the cloud. This works for confidential projects, NDA drawings and government contracts.

Is Ncored GDPR-compliant?

Yes. Ncored complies with the EU General Data Protection Regulation (GDPR). We only collect account data (email, licence status) and anonymous usage analytics if you consent. No drawing content, no personal tracking.

What stays on my computer after uninstalling?

After you uninstall Ncored, your PDF files stay untouched and readable in any other PDF tool — Acrobat, Preview, Foxit. Annotations and markups are saved directly into the PDF file, so they persist wherever the file is opened.

Who makes Ncored?

Ncored is built by Noir architects together with engineering teams in Vilnius — architects and engineers working on complex projects every day. We started building Ncored for ourselves because no fast PDF tool existed for our drawings. The company is registered in Lithuania.
