Construction-site documentation tool Gewerkton replaced the design across its web app, iPhone and Android apps, Studio and multilingual website on Oct. 2–3, 2026, according to the original project account from its developer, Thorsten Meyer. Meyer said AI coding agents handled implementation from written plans, while he approved the plans, reviewed the results and released each part.

The redesign, named HORIZON, covered 529 website pages in 40 languages, 26 icons and the product’s web and mobile interfaces. The account says the web app’s 281 hard-coded colour values were moved to design tokens, with 11 exceptions retained, and 47 cards were restyled. The mobile app was updated to version 0.5.0, while Gewerkton Studio received the new look in light and dark modes.

The website also received 228 AI-generated film runs for five regions, alongside eight help videos. According to the project record, 222 of the runs had their own regional version. The phrase “two days” describes execution from an approved plan to the live website, not the entire design process: an interim design draft had been carried forward from Sept. 26.

Meyer said the agents worked in a separate copy of the code on their own branch. Work was not merged or released until he approved each part. He also retained specific decisions, including approval of films showing the redesigned interfaces and permission for paid film reruns. An Apple developer agreement had to be accepted by Meyer before the iPhone build could proceed.

Human Review Shaped the AI Rollout

The account offers a detailed example of how a small software operation says it used AI agents for a broad product release without handing them final authority. Agents carried out implementation, but human review remained a release gate for code, visual output and spending. Apple’s agreement requirement also placed one step outside the agents’ control.

The reported defects show why those checks mattered. White tiles behind the first icon set obscured nearby labels in dark mode, a problem Meyer says he found through inspection rather than automated tests. Film recolouring also missed red details in shadows and warm lighting. A visual review led to edits and temporary use of European versions for 10 regional cuts with residual red; nine of those runs were later reshot and checked.

For readers evaluating claims about AI-assisted production, the account is useful as a description of workflow and failure handling, not as an independent assessment of speed or quality. Gewerkton is built by Thorsten Meyer, who also published the account on ThorstenMeyerAI.com. The disclosed relationship means the performance figures and account of the relaunch are the publisher’s own reporting, not independently verified results.

From Approved Plan to Live Design

Gewerkton is a construction-site documentation tool built in Iffeldorf, Bavaria. Meyer said he directed a fleet of coding agents, including Codex and Claude, for the relaunch. Rather than giving an agent an open-ended request to redesign the product, the process began with a written plan listing unresolved decisions, options and recommendations. Meyer approved the recommendations before implementation began.

The project account reports checks across multiple devices and languages. The web app was inspected in 200 views in English, German, Japanese and Hindi, at widths of 390, 834 and 1,440 pixels, in light and dark modes. It reported no overflow or console errors in that inspection. The mobile app’s test suite passed 853 of 853 tests, and Studio’s passed 2,158 of 2,158. The website passed seven test suites and was checked in five regions at three widths, including after upload.

Those green results did not mean every test was clean. The web app suite had eight failures across seven files; the account says six files failed the same way on the main branch and one failure depended on test order, passing when run alone. The developer said the redesign neither caused nor fixed those failures. Separately, an interim design draft dated Sept. 26 was part of the work, so the two-day execution window began with prior design work in hand.

“The two days cover the execution, from the approved plan to the live website.”

Independent Verification Is Not Provided

The reported tests, timings and output counts come from Gewerkton’s own project account. No independent audit or outside confirmation is included in the source material, and it does not provide a comparable baseline for how long the same work would have taken without AI agents. The figures therefore describe the developer’s account of this relaunch, not a controlled comparison of AI-assisted and conventional development.

The account gives an approximate $134 actual cost for the films, but does not provide a full cost breakdown for the wider redesign or quantify staff time. It also does not explain how the cost figure treats failed or repeated generation attempts beyond saying 76 failed jobs were not billed. The remaining five significant findings from the Pixel 10a Android test are not individually described; the account says none was a blocker and that all five are scheduled for version 0.5.1.

Mobile Fixes Are Planned for 0.5.1

Gewerkton’s next stated product step is version 0.5.1, which is scheduled to address five major findings from testing on a Pixel 10a. One described issue affects camera-screen buttons: larger type and padding caused labels to break mid-word, including the German word for “cancel,” which wraps onto two lines. The company said the findings were not release blockers, but it has not provided a release date in the source material.

The film work also included additional visual review and approved reshoots. The account says nine regional runs with remaining red details were later reshot and passed a visual check. It does not provide a timetable for any further film changes or a separate post-launch review of the full relaunch.

Key Questions

What changed in the Gewerkton relaunch?

The HORIZON design was applied to the web app, iPhone and Android apps, Studio, 26 icons and a 529-page website in 40 languages. The site also received 228 film runs for five regions and eight help videos, according to the developer’s account.

How did AI agents take part?

Gewerkton says Codex and Claude agents implemented work from written plans in a separate code branch. Thorsten Meyer approved the plans, reviewed results and authorized releases; some film reruns and the Apple developer agreement also required his direct approval.

Was the whole relaunch completed from scratch in two days?

No. The two-day period refers to execution from the approved plan to the live website on Oct. 2–3, 2026. The project account says an interim design draft from Sept. 26 was already available.

What problems did the team report?

The initial icons obscured labels in dark mode, and automated film recolouring missed some red details while also producing unwanted changes in other attempts. A Pixel 10a test found five major issues, including camera-screen buttons whose text wrapped; all five are scheduled for version 0.5.1.

Are the relaunch results independently verified?

The source is the developer’s own account, and Gewerkton discloses that it is built by the publisher. The supplied material does not include an independent audit or a comparison with a non-AI workflow.
