Subcontractor closes it out

The subcontractor gets the report with a timestamp. Status updates flow back to you. No WhatsApp archaeology when you need to prove it was flagged.

How it works: our document pipeline.

Here's exactly what happens after you upload a document. Transparency is how we earn the trust that a black-box AI tool never can.

Stage 1 of 7

Ingest

Upload from SharePoint, OneDrive, or direct drop. Supported: PDFs, vector CADs, DOCX, XLSX, and regulatory feeds. Everything enters an EU-hosted pipeline.

Real questions we get on sales calls.

If yours isn't here, book a meeting and ask.

Three things. First, your data stays in the EU — ChatGPT and NotebookLM both process in the US. Second, the system understands construction: EN/ISO standards, Estonian building codes, defect acknowledgment flows. A generic tool doesn't. Third, every answer cites the exact source page, not a probabilistic summary. You can defend it in an audit.

In EU data centres — Cloudflare's EU network. Nobody from the platform accesses your documents without your knowledge. There is no manual review of uploads. You can export or delete everything at any time.

The capture flow works offline. Photos, voice notes, and locations queue on the phone. When signal comes back, reports send and the queue clears. You see exactly what's pending, so nothing gets lost on a staircase with no bars.

Worth a 30-minute call?

We'll show you the chat flow on a real project and you'll know in 10 minutes whether it fits. No pitch deck — one of the founders joins every call.
