How It Works

01

CONNECT YOUR CREWS

That's it — no new apps for your team. Crews keep using WhatsApp. We'll get you started in less than a week.

02

CREWS REPORT FROM THE FIELD

A crew member sends voice notes and photos as they normally do. Vistwerk captures everything in real time.

03

GET AUDIT-READY DOCUMENTS

AI structures the data, generates compliant documents, and validates against operator requirements — ready to submit.

Demo video coming soon

Intelligence from the field to the office.
One platform to manage it all.

FIELD CAPTURE

Capture field data without changing crew habits

Groq Whisper transcribes German voice notes in sub-second time. Field crews speak naturally via WhatsApp — the system structures everything.

QUALITY ASSURANCE

Validate every photo before it leaves the site

AI analyzes site photos for cable routing, splice quality, and installation compliance. Low-confidence results get flagged for review.

DOCUMENT AUTOMATION

Generate audit-ready documents automatically

Bautagebuch, Messprotokoll, Muffenprotokoll, and Aufmaß — generated automatically in each operator's required format.

What our customers say

How fiber-optic contractors put their evenings back.

5.0
2 hrs/day saved
Before Vistwerk my Bauleiter spent two hours every evening rebuilding the day from memory into Excel. Now the crews send their WhatsApp voice notes from the trench and the Tagesbericht is basically written before he gets back to the office.
ABAndreas BrücknerManaging Director · Brückner Tiefbau GmbH
4.9
40% faster billing
Our Aufmaß used to lag two months behind the actual work, so we were always waiting on payment. With the daily extraction we close the quantity survey the same week the trench is dug, and the invoices go out far sooner.
KVKatrin VogelsangProject Manager · Rheinpfalz Netzbau GmbH
4.8
5 crews, one system
We coordinate five subcontractor crews on the same Telekom rollout and every one of them used to document differently. Now every Bautagebuch comes out in the same format, so the audit trail finally holds together.
MDMurat DemirciHead of Operations · Maintal Glasfaserbau GmbH
4.7
Codes caught, not lost
I was sceptical that an AI could understand a crew member mumbling HK and NVt codes into a voice note in the wind. It transcribes the German correctly and flags anything it is unsure about for me to check, which is exactly what I wanted.
SHStefan HollmannSite Manager · Hollmann Straßen- und Tiefbau GmbH

Days to an afternoon
When Telekom asked for our completion notice and the photo documentation, we used to scramble for days digging through phones. The Fertigstellungsanzeige and Fotodokumentation are now assembled from what the crews already sent, so it took an afternoon.
BSBirgit SauerlandDocumentation Lead · Westfalen Infrastruktur GmbH

Weekly report in minutes
The Rückmeldedatei against the Bauzeitenplan used to be a Friday afternoon battle with the original Excel template. Vistwerk fills the actual progress straight into our own file, so the weekly report to the client is no longer a fight.
TRTobias ReinhardtProject Manager · Elbtal Bauunternehmen GmbH

Evenings back
As a smaller firm we do not have a back-office documentation team, it was always me at the kitchen table at night. Letting the crews just send photos and a quick voice note gave me my evenings back without losing the paper trail.
JOJens OttmannManaging Director · Ottmann Erd- und Tiefbau GmbH
4.9
Zero audit findings
We passed our last documentation audit without a single open finding, which has never happened before. Having every Bautagebuch and Aufmaß consistent across all our subcontractors is what made the difference.
