TL;DR
Gewerkton says AI coding agents implemented its HORIZON redesign across its apps, Studio, icons and multilingual website on October 2–3, 2026. The company reports extensive automated testing, but also describes visual defects and failed film runs that required human review and correction.
Gewerkton says it replaced the look of its web app, iPhone and Android apps, Studio, icons and multilingual website with a design called HORIZON during work on October 2–3, 2026. The company used AI coding agents to implement plans approved by founder Thorsten Meyer, who reviewed and released each part; the original account also records defects and film-generation failures that needed human intervention.
The redesign covered 281 hard-coded web-app colours, moved to design tokens with 11 exceptions retained, and restyled 47 cards. The phone app moved to the new look in version 0.5.0, while Studio received light and dark versions. All 26 icons were re-rendered in Blender in cobalt and navy. The website’s 529 pages, available in 40 languages, received a new opening section featuring product screens, and Gewerkton says AI agents are increasingly used to find services; 1,583 files uploaded without error.
The website also received 228 AI film runs for five regions, of which 222 had their own regional version, plus eight help videos. The company qualifies its “two days” description: an interim design draft dated September 26 was already available, so the two-day period refers to execution from an approved plan through the live website, not design work starting from scratch.
According to the account, Codex and Claude agents worked in a separate code copy and branch. Meyer approved the written plan and released each stage before it was merged or delivered. He also approved paid film reruns and checked app footage before it was used. An Apple Program License Agreement blocked the iPhone build until Meyer accepted it himself. The report does not provide independent verification of the results.

The Two-Day Brand Rebuild: Gewerkton’s AI Agents In Action
A first-party account of a fast HORIZON redesign spanning apps, Studio, icons and a 529-page multilingual website—with human release gates, measurable checks and visible failures along the way.
“The two days cover the execution, from the approved plan to the live website.”
ThorstenMeyerAI.com · project reportScope note An interim design draft dated September 26 already existed. The two days describe implementation and release, not design from scratch.
01 / What changed
A brand system across the product
Gewerkton says the HORIZON look reached product interfaces and customer-facing media. Eleven legacy color exceptions remained after tokenization.
From hard-coded to tokenized
281 hard-coded colors moved to design tokens. The team retained 11 exceptions and restyled 47 cards.
Interfaces brought into HORIZON
The phone app adopted the new look in version 0.5.0. Studio received both light and dark versions.
Icons and regional content
All 26 icons were re-rendered in Blender in cobalt and navy. The website gained a new opening section with product screens.
The report says 1,583 files uploaded without error. It also describes AI-assisted service discovery across the multilingual site.
228 AI film runs covered five regions; 222 reportedly had their own regional version. Eight help videos were also produced.
02 / Release path
Human approval stayed in the loop
Agents implemented work from an approved written plan on a separate code copy and branch. The founder reviewed results and released each stage.
Plan
Options, unresolved decisions and recommendations were written down.
Approve
Thorsten Meyer approved the plan before agents began implementation.
Implement
Codex and Claude agents worked on a separate branch; deviations were logged.
Review + release
Meyer checked each stage before merge or delivery, including film reruns.
03 / Reported checks
Broad coverage, mixed signals
The publisher reports extensive automated and browser testing. Its own account also records missed visual defects and unresolved test failures.
Reported test coverage
Contrast correction
The original cobalt measured 4.38:1 against a light background, below Gewerkton’s stated 4.5:1 working threshold based on WCAG 2.1 AA. The team darkened the color.
Scale shown from 0 to 6:1. Both values are reported by the publisher.
04 / Defects + recovery
Automation did not catch everything
Human inspection surfaced interface issues and film failures. The report describes fixes and workarounds, with some follow-up still open.
Dark-mode icon tiles
White tiles covered nearby labels. Meyer spotted what automated checks missed; the team made the icon areas transparent, added a dark variant and corrected a layout rule.
Color masks fell short
Red-removal masks missed shadows and warm light. Broader recoloring affected lips, faces and stickers. The report says 24 files were cleaned manually.
Camera controls wrapped
A Pixel 10a test found five issues after larger text and padding made buttons break mid-word, including a two-line German cancel label.
Production paused after round nine: 208 of 228 runs were complete and 38% of jobs were failing. Gewerkton says 76 failed jobs were not billed; nine regional versions were later reshot after review.
Eight tests failed across seven files. Six files reportedly fail the same way on the main branch; one depends on test order and passes alone. The publisher says the redesign did not cause or resolve them.
05 / What remains
Follow-up items are still visible
The account does not confirm later delivery or a complete final accounting. The reported results should be read as first-party claims.
Mobile fixes planned
Five Pixel 10a findings were scheduled for version 0.5.1. The report does not state whether that update has shipped.
Final variation status
Nine regional versions were reshot and passed visual review. The account gives no final status for every variation.
Partial cost figure
The report mentions about $134 in actual film costs, then stops short of stating the full project cost or other expenses.
Gewerkton is built in Iffeldorf, Bavaria, by Thorsten Meyer. ThorstenMeyerAI.com, the report’s publisher, discloses that it builds Gewerkton. The figures and account of the work have not been independently verified.
06 / Key questions
How to read the two-day claim
What changed?
The HORIZON design reached the web and phone apps, Studio, 26 icons and a 529-page website. The work also included 228 AI film runs and eight help videos.
Did the whole redesign take two days?
The reported execution ran October 2–3, 2026, from approved plan to live site. An interim design draft already existed from September 26.
Could agents release changes alone?
According to the account, Meyer approved the plan and released each stage. He also approved paid film reruns and accepted Apple’s license agreement for the iPhone build.
What remains uncertain?
The account leaves open the status of version 0.5.1, all film variations, web-app test failures and the project’s complete cost.
Human Review Shaped the Release
The project offers a concrete account of AI agents working across a software product and its marketing assets, while showing that rapid implementation did not eliminate human decision-making. Plans, staged releases and explicit approval gates limited what the agents could ship on their own. Some problems, however, appeared only when a person inspected the interface or generated footage.
Gewerkton says the original cobalt did not meet its working contrast threshold: it measured 4.38:1 against a light background, below the company’s 4.5:1 standard based on WCAG 2.1 AA. The team darkened it to 4.80:1. In another visual issue, white icon tiles covered nearby labels in dark mode. Meyer spotted the problem; the automated checks had not. The team made icon areas transparent, added a dark variant and corrected a layout rule before releasing the fix that evening.
The film work illustrates the limits of automated image processing. Red-removal masks missed red in shadows and warm lighting, while broader recolouring attempts affected lips, faces and stickers. The reported fixes included manually reviewing footage, cleaning 24 files and temporarily using the European cut for 10 regional versions. These are the publisher’s account of its own product work, not an independently audited evaluation of AI-agent performance.

From Approved Plan to Live Site
Gewerkton is a construction-site documentation tool built in Iffeldorf, Bavaria, by Thorsten Meyer. The source report is published by ThorstenMeyerAI.com and discloses that its publisher builds Gewerkton. That relationship matters when interpreting the release figures and the account of how the work was managed: they are first-party claims.
The work began with a written plan listing unresolved decisions, available options and recommendations. Meyer approved the recommendations. Agents then implemented the work on a separate branch, while the founder reviewed results and controlled releases. The report says deviations from the plan were logged and the more conservative option was chosen when the original approach did not hold up.
Checks included 200 web-app views across English, German, Japanese and Hindi; widths of 390, 834 and 1,440 pixels; and light and dark modes. Gewerkton reports no overflow or console errors in those checks. Its phone app passed 853 of 853 tests, Studio passed 2,158 of 2,158, and the website passed seven test suites and browser checks across five regions. The live website was checked again after upload.

Failures and Fixes Still in View
The report says eight web-app tests failed across seven files. Six files reportedly fail in the same way on the main branch, while another failure depends on test order and passes when run alone. Gewerkton says these failures were not caused by the redesign, but also says the redesign did not resolve them. No independent test results or detailed test logs are provided.
Film production was paused after round nine, when the company says 38% of jobs were failing and 208 of the 228 runs were complete. The 76 failed jobs were not billed, according to the report. The company says it later reshot nine regional versions after visual review and approval. It also says 80 industry clips were redone because the first image model had made little change to faces.
The report gives an Android test on a Pixel 10a as one source of five major findings: larger text and padding caused camera-screen buttons to break mid-word, including a German cancel label wrapping onto two lines. Gewerkton says none of the five findings blocked release and that they were scheduled for version 0.5.1. The material provided does not state whether that update has since shipped. It also ends its cost discussion after saying the project records show about $134 in actual film costs, without specifying the full project cost or whether other expenses were included.

Version 0.5.1 and Remaining Film Work
Gewerkton’s stated next software step is version 0.5.1, which is scheduled to address the five findings from the Pixel 10a camera-screen test. The source account does not confirm a release date or say whether the fixes have been delivered since the October 2–3 redesign.
The report says nine regional film versions were later reshot with Meyer’s approval and passed visual review. It does not give a final status for every film variation or a complete accounting of the project’s costs. Those details, along with the status of the web-app test failures, remain the clearest items for a follow-up.

Key Questions
What did Gewerkton change during the redesign?
Gewerkton says it applied the HORIZON design to its web and phone apps, Studio, 26 icons and 529-page website. The work also included 228 AI film runs for five regions and eight help videos.
Did the entire redesign take only two days?
The publisher says execution took place on October 2–3, 2026, from an approved plan through the live website. An interim design draft dated September 26 already existed, so the design process did not start from nothing on October 2.
Were the AI agents allowed to release changes on their own?
According to the report, no. The agents worked on a separate branch, and Thorsten Meyer approved the plan and released each part. He also had to approve paid film reruns and accept Apple’s license agreement before the iPhone build could proceed.
What problems did the team report?
The account describes dark-mode icon tiles covering labels, film masks missing red in shadows, and Android camera-screen buttons wrapping awkwardly. It also reports eight web-app test failures, which Gewerkton says were not introduced by the redesign.
What is the next stated update?
Gewerkton said five findings from an Android test were scheduled for version 0.5.1. The source material does not confirm whether that release has shipped or provide a date.
