TL;DR
Construction-site documentation tool Gewerkton says AI coding agents implemented its HORIZON redesign across its web and phone apps, Studio, icons and multilingual website on Oct. 2–3, 2026. The two-day claim describes execution from an approved plan, not a design created from scratch; the company’s founder reviewed and released each part, and the work included human-led visual checks and corrections.
As described in the original analysis, Gewerkton says AI coding agents implemented a new design called HORIZON across its web app, iPhone and Android apps, Studio, 26 icons and a website spanning 40 languages on Oct. 2–3, 2026. The construction-site documentation tool’s founder, Thorsten Meyer, approved the written plan, reviewed results and released each part; the project is a company-reported case study, not an independently verified benchmark of how quickly AI can refresh a brand.
The reported scope included moving 281 hard-coded web-app colors into design tokens, restyling 47 cards and updating the phone app to version 0.5.0. The Studio received light and dark versions of the design, while all 26 icons were re-rendered in Blender. The website’s 529 pages were updated in 40 languages, and Gewerkton says 1,583 files uploaded without an error.
The two-day description has an important qualification: an interim design draft dated Sept. 26 was used as a starting point. Gewerkton describes Oct. 2–3 as the execution period, from an approved plan to a live website—not as two days to develop the brand concept from scratch. The publisher of the account also discloses that it built Gewerkton itself.
The website received 228 AI film runs for five regions, including 222 with their own regional version, plus eight help videos. These production runs were not all completed smoothly. Gewerkton says work paused after round nine, when 208 of 228 runs were complete and 38% of jobs were failing; 76 failed jobs were not billed. The source gives an approximate cost of $134 for the films, but the available material does not clarify the full cost of the overall redesign.

Gewerkton project disclosure“Where the plan did not hold up, the deviation was logged and the conservative option taken.”
Gewerkton project account03 · Checks and judgment
Automation covered a lot. People still had to look.
Gewerkton reports extensive testing, including broad web-app coverage and complete passing counts for Studio and the phone app. The figures describe checks reported by the company; they do not show that another product would see the same speed or results.
Web app checks spanned four languages, three screen widths, and light and dark modes. The website passed seven test suites.
04 · Quality decisions
Corrections, costs and remaining work
Contrast improved
The chosen cobalt measured 4.38:1 against a light background, below the stated 4.5:1 working standard. It was darkened to 4.80:1.
A pause after round nine
208 of 228 runs were complete when work paused; 38% of jobs were failing. Gewerkton says 76 failed jobs were not billed.
More review and reruns
24 files were cleaned. Ten regional versions temporarily used the European cut; nine were later reshot with approval.
Eight tests still failed
Failures spanned seven files. The company says six files also fail on the main branch and one test depends on run order.
Five major findings
Issues included camera-screen buttons breaking mid-word. None was classified as a blocker; all were assigned to version 0.5.1.
Partial cost disclosed
The source gives an approximate $134 cost for films. It does not provide the full redesign budget or comparable costs for coding, design, testing or staff time.
05 · Read the claim carefully
A reported case study, with limits
An interim design draft preceded the October execution window.
Scheduled to address five Android findings; no release date was given.
Timing, scope and test figures come from Gewerkton’s account and have not been independently audited.
The account does not give the final status of every regional film or establish whether all temporarily replaced versions returned to their intended cuts. It also does not include an independent performance comparison.
06 · Key questions
What the two-day claim means
What did Gewerkton change?
It reports implementing HORIZON across the web app, iPhone and Android apps, Studio, 26 icons and a 529-page website in 40 languages, alongside regional films and help videos.
Was the brand designed from scratch in two days?
No. The project account says an interim design draft from September 26 was the starting point. The two days refer to execution from an approved plan to a live website.
Was the rollout fully autonomous?
No. The founder approved plans and releases, authorized some actions, and used visual review to catch issues automated tests missed.
Does this prove the same speed for other teams?
No. It is a company-reported case study, without an independent audit or comparison across products and teams.
What the Two-Day Schedule Required
The account offers a practical example of where AI agents can contribute to a tightly managed software and design rollout—and where human review remains necessary. The agents implemented work from written plans in a separate code branch, while Meyer approved the plan and controlled releases. Some actions, including accepting an Apple program agreement and approving paid film reruns, required his direct authorization.
Gewerkton reports extensive testing: the web app was checked across 200 views, four languages, three screen widths and light and dark modes. The phone app passed 853 of 853 tests, the Studio passed 2,158 of 2,158, and the website passed seven test suites. Those figures describe checks reported by the company; they do not establish that the process will produce the same speed or results for other products.
The work also shows why passing automated tests did not settle whether the redesign was ready. Meyer found that white tiles behind the new icons obscured neighboring labels in dark mode, a problem no test had flagged. Film recoloring likewise needed human inspection after automated masking missed red in shadow and warm light. The case therefore points to a workflow combining automation with human judgment, rather than a fully autonomous redesign.

From Approved Draft to Live Release
Gewerkton is a documentation tool for construction sites, built in Iffeldorf, Bavaria, by Thorsten Meyer. According to the disclosed project account, Meyer directs AI coding agents from Codex and Claude. For this redesign, agents worked from written plans that listed open decisions, options and recommendations. Meyer approved the recommendations, and the work was kept in a separate copy of the code on its own branch until he released each component.
The project account says deviations from the plan were recorded and handled conservatively. For example, the chosen cobalt color reached a contrast ratio of 4.38:1 against a light background, below Gewerkton’s stated working standard of 4.5:1 under WCAG 2.1 AA. The team darkened it to 4.80:1 rather than shipping the original shade.
Visual review was part of the production process as well as the app checks. The middle frame of each of 157 mirrored films was inspected, and reworked films were viewed again at 10%, 50% and 90% of their duration. Gewerkton says the first 80 industry clips were redone because the initial image model had changed faces too little. These details come from the company’s own account and have not been independently audited.

Costs, Defects and Verification
The account does not provide a complete budget for the redesign. It gives an approximate $134 actual cost for the films, but does not specify the accounting scope or give comparable figures for coding, design, testing or staff time. The reported completion time and test results are Gewerkton’s own figures; no independent performance comparison is included.
Some reported issues remained unresolved at publication. Eight web-app tests failed across seven files; Gewerkton says six files also fail on the main branch and one test depends on run order and passes alone. The redesign did not cause those failures, according to the account, but it did not fix them. The Android test also found five major issues, including camera-screen buttons that break mid-word; none was classified as a blocker, and all five were assigned to version 0.5.1.
The film cleanup required additional work. Gewerkton says 24 files were cleaned after visual review, and 10 regional versions with remaining red were temporarily replaced with the European cut. Nine were later reshot with Meyer’s approval. The source does not give a final status for every film or explain whether all regional versions have since returned to their intended cuts.

Version 0.5.1 and Film Revisions
Gewerkton’s stated next app milestone is version 0.5.1, which is scheduled to address the five major findings from the Android test. The company account does not give a release date. The remaining web-app test failures are described as pre-existing or dependent on test order, but no timetable for resolving them is provided.
Further film work may also follow: nine regional runs were reshot and passed visual review, while the account says 10 regional versions were temporarily switched to the European cut. It does not establish whether the last version in that group has been reshot, or whether additional corrections are planned. For now, the project’s reported outcome is a live redesign delivered over two execution days, with its scope, quality checks and remaining work documented by the publisher that built the product.

Key Questions
What did Gewerkton change in two days?
Gewerkton says it implemented the HORIZON look across its web app, iPhone and Android apps, Studio, 26 icons and a website with 529 pages in 40 languages. The website also received regional AI film runs and help videos.
Was the brand designed from scratch in two days?
No. The project account says an interim design draft from Sept. 26 was carried into the Oct. 2–3 execution. The two-day claim refers to implementation from an approved plan through the live website.
Did AI agents work without human supervision?
No. Thorsten Meyer approved the plan and released each part after reviewing it. He also handled approvals that agents could not take, including an Apple program agreement and paid film reruns. Human visual checks found issues that automated tests and image masks missed.
What problems were found during the redesign?
White icon tiles obscured labels in dark mode, and automated film recoloring missed red in shadows and warm light. An Android camera screen also had buttons that broke mid-word. Gewerkton says fixes were made for the icon issue and that five major Android findings were scheduled for version 0.5.1.
How much did the redesign cost?
The project account gives an approximate actual cost of $134 for the film work. It does not provide a full budget for the redesign or a breakdown of other costs.
