Construction sites generate a constant stream of decisions, instructions, photographs, deadlines and signatures. Capturing all of that accurately is difficult when the person responsible is standing on scaffolding, moving between trades or working in a location with unreliable connectivity. Gewerkton approaches the problem from a practical starting point: let people speak first, then turn what they say into structured project evidence.
Gewerkton · The construction record
The best record starts with a voice.
Gewerkton begins where construction evidence is hardest to capture: on scaffolding, between trades and inside connectivity dead zones. Speak first; structure the proof around the observation.
Field
Voice-first capture at the point of work, including offline environments.
Studio
A browser workspace for existing plans and models—or for creating a model when none exists.
Cloud
Operational and data coordination across Field, Studio and third-party systems.
One founder directs an agent fleet
Codex and Claude support a build spanning field capture, browser modelling, cloud coordination, commercial integrations and global languages.
21 software packages shipped in one night, verified with negative controls and mutation testsPublic beta planned
The proposition is defined, but Gewerkton is still moving toward broader public release.
The platform is being built by a solo founder directing a fleet of coding agents using Codex and Claude. That unusual development model gives Gewerkton a human story that is as notable as its technical scope. The project combines voice-led site work, browser-based planning and cloud coordination in one branded house, with 27 content languages and a choice of AI providers across Europe, the United States and Asia, including mainland China.
Gewerkton is in beta now, with a public beta planned for fall 2026. That status matters: this is a platform still moving towards its broader public release, not a finished product being presented as universally available today.

From spoken observation to structured evidence
The central idea is easy to understand even without construction experience. Someone on site dictates what has happened or what needs attention. That record can become structured evidence connected to a photo, deadline and signature. Instead of treating speech as a secondary convenience, Gewerkton makes it the starting point for construction documentation and defect management.
Its marketing line captures that focus: “On site, what counts is what’s proven.” The emphasis is not simply on recording more information. It is on connecting the original site observation with the material needed to make the record usable across the project.
The voice-first approach runs through the Gewerkton platform, but the system is divided into three product lines with distinct roles: Field, Studio and Cloud. Together, they cover capture on site, work with plans and models in the browser, and coordination between project data and outside systems.

Field puts the site record where the work happens
Gewerkton Field is the voice-first construction site app. It turns dictation into evidence, defects and daywork reports, while also covering takt and portal functions. Takt refers to organising work in a planned rhythm, so different trades can move through a project in a coordinated sequence.
The app’s role changes with the type of job, but the underlying pattern stays consistent: capture information while it is still close to the event. In housing and building construction, that can mean recording a defect with a photo and deadline, dictating a daywork report, or collecting a signature on the device during handover.
On wind farms and renewable-energy projects, the challenge includes distributed sites, rotating crews and field acceptance. Offline capture is relevant where dead zones make a continuous connection unrealistic. For infrastructure and tunnel projects, which may run for long periods and involve many change orders, instructions can be backed by the original audio.
That original record is particularly important for cross-border teams. Gewerkton supports teams in the EU, US and APAC working on the same project in their own languages while keeping the evidence original unambiguous. On projects in Asia, Chinese, Korean and Vietnamese crews can work in a multilingual process extending from capture through to the report.

Studio works with plans, models and sites without models
Voice capture is only one part of the construction record. Site information also has to connect with the plans and models used to understand the job. Gewerkton Studio is the browser workspace for that part of the platform.

Studio is designed for work with plans and models. Where no model exists, the site team can create one directly in the browser. That distinction makes the product relevant beyond projects that already arrive with a complete digital model. The browser becomes both a place to use existing project material and a place to establish the missing model when the team needs one.
For data centres and industrial plants, many trades may be active in parallel under tight deadlines. Gewerkton’s workflow can turn decisions made in meetings into task lists sorted by trade. This gives the spoken or discussed decision a route into organised project work rather than leaving it isolated from the people responsible for acting on it.
Studio therefore carries a different part of the story from Field. Field begins with what someone encounters and records on site. Studio provides the browser environment in which plans and models can be used or created. The two are separate product lines, but their information is intended to remain coordinated.

Cloud connects the moving parts
Gewerkton Cloud handles operations and model or data coordination between Field, Studio and third parties. Its place in the platform is connective: it supports the movement and coordination of information generated on site and handled in the browser workspace.
Data residency is presented as a choice. Customers can use an EU cloud or their own infrastructure. Gewerkton also offers regional AI-provider selection, covering providers in the EU, US and Asia, including mainland China. For projects in Asia, that provider choice sits alongside multilingual capture and reporting, with data residency selected according to the project’s needs.
The broader AI model is described as BYO-AI, or bring your own AI. Gewerkton supports 13 AI providers, allows users to bring their own keys and lets them select a region. The stated aim is to avoid vendor lock-in rather than requiring every project to depend on a single AI supplier.
German commercial depth, global working languages
Gewerkton was born in the German market and has its deepest commercial integration there. The named integrations are GAEB, REB, XRechnung and DATEV. These cover established parts of German construction, billing, calculation and accounting workflows, giving the platform a specific commercial foundation alongside its international ambitions.

At the same time, Gewerkton is positioned for global markets. Its 27 content languages are not limited to a translated marketing surface; the platform is intended for multilingual work from capture to report. That matters on projects where crews, project managers and commercial teams may not share one working language.
The marketing site also runs in 27 languages. It uses zero trackers, requires no cookie banner and has a fully egress-free architecture. Gewerkton has additionally produced a media bank containing more than 51 self-produced clips and posters. Those details show the breadth of the launch preparation around the beta, extending from the product itself to how its story is presented.
A solo founder with an agent fleet
The development setup is unusually concentrated. One founder directs a fleet of coding agents powered by Codex and Claude. In one night, that fleet shipped 21 software packages. The work was verified with negative controls and mutation tests, methods intended to check whether tests can detect failures and deliberately introduced changes.
That does not alter the current product status: Gewerkton remains in beta, and its public beta is planned for fall 2026. It does, however, explain how a solo founder is attempting to build across field capture, browser modelling, cloud coordination, commercial integrations, regional infrastructure choices and 27 languages.
The result is a construction platform built around a straightforward observation. The most useful time to document site activity is while the person who saw it can still speak to what happened. Gewerkton’s three product lines then give that spoken record somewhere to go: Field structures it on site, Studio connects it with plans and models, and Cloud coordinates the operational data around both.
For distributed renewable projects, complex industrial plants, housing, tunnels, infrastructure and multilingual cross-border teams, the circumstances differ sharply. Gewerkton’s common thread is the attempt to preserve what was said, connect it with evidence and carry it into the wider project record. The platform is not at public release yet, but its beta already sets out a clear proposition: dictate at the point of work, then organise the proof around the people, places and deadlines that matter.
