TL;DR
Gewerkton says AI coding agents carried out a redesign across its web and phone apps, Studio, icons and multilingual website on Oct. 2-3, 2026. The publisher says people approved the plans and releases, checked visual work and handled decisions agents could not make; the work also exposed missed defects and left five Android findings for version 0.5.1.
Gewerkton, a construction-site documentation tool built by the publisher of the source account, replaced the look of its web and phone apps, Studio, 26 icons and multilingual website on Oct. 2-3, 2026. The company says AI coding agents handled implementation from written plans, while founder Thorsten Meyer approved the plans, reviewed results and released each part; the original account also describes defects that required human inspection and fixes.
The redesign, called HORIZON, covered the web app, iPhone and Android apps, Studio and a website with 529 pages in 40 languages. The web app’s 281 hard-coded color values were moved to design tokens, with 11 exceptions retained, and 47 cards were restyled. Phone app version 0.5.0 adopted the new look, while Studio received light and dark versions. The 26 icons were re-rendered in Blender in cobalt and navy.
The website also received a new opening section featuring product screens. Gewerkton says it uploaded 1,583 files without an error and produced 228 AI film runs for five regions, including 222 regional versions, as well as eight help videos. The company qualifies the two-day timeline: a draft of the design dated Sept. 26 informed the work, so the redesign did not begin from scratch on Oct. 2. The stated window refers to execution from approved plan to live website.
According to the account, agents worked in a separate code copy on their own branch. Meyer approved the plan and released each section after reviewing it. Films showing the apps were held until he had seen and approved the new interface on Oct. 3, and paid film reruns needed explicit permission. Apple also blocked the iPhone build until Meyer personally accepted an updated Program License Agreement.

How AI Agents Shaped Gewerkton’s New Look In Two Days
Gewerkton says AI coding agents implemented its HORIZON redesign across apps, Studio, icons and a multilingual website. The two-day window began from an earlier design draft and included human review, decisions and corrections.
A broad release, on a short clock
Execution ran October 2–3, 2026, from an approved plan informed by a September 26 draft.
One redesign touched five surfaces
The HORIZON refresh reached product interfaces and the public site, alongside localized media and help content.
Apps refreshed
The web app moved 281 hard-coded color values into design tokens, kept 11 exceptions and restyled 47 cards. Phone app version 0.5.0 adopted the new look.
Two visual modes
Studio received light and dark versions. The publisher reports 2,158 of 2,158 Studio tests passed.
Cobalt and navy
All 26 icons were re-rendered in Blender using the refreshed cobalt and navy palette.
New opening section
The 529-page multilingual website gained a new opening section featuring product screens.
Localized films
Gewerkton reports 228 AI film runs, including 222 regional versions, plus eight help videos.
Not from scratch
A September 26 design draft informed implementation. The two days refer to execution from approved plan to live website.
Approval stayed in the loop
Agents worked from written plans on a separate code copy and branch. People made release and judgment calls.
Plan
Open decisions, options and recommendations were written down; Meyer approved the plan.
Implement
Coding agents carried out the approved changes across apps, Studio and website.
Inspect
People reviewed interfaces and films, finding visual defects automated checks missed.
Release
Meyer approved each section. Paid film reruns needed explicit permission; Apple required his license acceptance for the iPhone build.
Passing tests did not catch every defect
The company reports broad checks, while also describing issues found by visual inspection and device testing.
Reported checks
Across four languages, three screen widths, and light and dark modes.
Also checked in a browser across five regions.
Adjustments in execution
The original shade was below Gewerkton’s stated 4.5:1 working standard; it was darkened.
Production paused after round nine when 38% of jobs were failing. The company says 76 failed jobs were not billed.
Review found white icon tiles obscuring dark-mode labels and red objects left in recolored footage. Both required manual correction.
“The two days cover the execution, from the approved plan to the live website.”
— Gewerkton’s publisher accountSome questions remain open
The account is a disclosure from the product’s publisher, which says it built Gewerkton. Its figures are company-reported in the supplied material.
Visual checks found white tiles covering nearby labels in dark mode; the issue was fixed the same evening. Film recoloring also missed objects in shadow or warm light. After review, 24 files were cleaned and 10 regional versions temporarily used the European cut; nine runs were later reshot and checked.
On a Pixel 10a, larger type and padding caused camera-screen buttons to break across words. Gewerkton calls this one of five major Android findings, none a blocker, and schedules all five for version 0.5.1.
- Web tests: Eight failures across seven files were reported. The account says six fail the same way on the main branch and one is run-order dependent; logs were not supplied.
- Android: Five findings are scheduled for version 0.5.1. No release date or full list is provided.
- Film status: The final disposition of every affected regional cut is not stated.
- Costs: The account mentions about $134 in actual film costs but gives no complete breakdown or comparison basis.
Version 0.5.1 is the next stated milestone
Five Android findings remain on the list
Gewerkton says the findings are scheduled for the next version, but gives no release date. Further clarity would come from the final regional film status, full cost records and details of outstanding web-test failures.
What the two-day claim means
What changed?
The HORIZON redesign covered web and phone apps, Studio, 26 icons and a 529-page website in 40 languages, plus regional films and help videos.
Did it start and finish in two days?
Implementation ran October 2–3, 2026, from an approved plan informed by a September 26 draft. It was not the entire design process.
Did agents make every decision?
No. Agents implemented written plans; people approved the plan and releases, reviewed results and authorized paid reruns.
Can this establish a general AI timeline?
No. It describes one publisher’s workflow and does not independently establish how quickly or reliably other teams could reproduce it.

Human Checks Shaped the AI Workflow
The account offers a specific example of how a company used AI agents for a broad software and media rollout without handing them final authority. Agents carried out implementation, but plan approval, release decisions and paid reruns remained with Meyer. Some actions were constrained by outside systems, including Apple’s agreement requirement.
The work also shows why automated tests alone did not establish that the redesign was ready. Gewerkton says tests passed for the phone app, Studio and website, but a person spotted white icon tiles obscuring nearby labels in dark mode. Visual review also found red left in recolored film footage after an automated mask missed objects in shadow or warm light. Those examples matter to readers evaluating claims about AI-led production: the stated speed depended on prior design work, review gates and manual correction, not just agent execution.
The source is a disclosure by the product’s publisher, which says it built Gewerkton and is documenting what it learns. Its figures and account are therefore company-reported rather than independently audited in the supplied material. The case is useful as a description of one workflow, but does not by itself establish how quickly or reliably other teams could reproduce it.

A Sept. 26 Draft Set the Starting Point
The two-day claim describes the execution period, not the full design process. Gewerkton says an interim design draft from Sept. 26 was carried into the Oct. 2-3 implementation. Before work began, the plan listed open decisions, options and recommendations; Meyer approved the recommendations. When the plan did not hold up, the team recorded deviations and chose a conservative alternative.
One example involved the brand’s cobalt color. The original shade measured 4.38:1 contrast against a light background, below Gewerkton’s stated working standard of 4.5:1 under WCAG 2.1 AA. The company darkened it to reach 4.80:1 rather than using the original shade. This was a design adjustment made during execution, not evidence that every planned choice went unchanged.
The rollout also had separate quality checks for software, website and video. Gewerkton says the web app was inspected across 200 views, four languages, three screen widths and light and dark modes. It reports 853 of 853 phone-app tests and 2,158 of 2,158 Studio tests passed; the website passed seven test suites and was checked in a browser across five regions. The source does not provide independent test records.

Some Defects and Costs Need More Detail
The account says eight web-app tests failed across seven files. Six files reportedly fail the same way on the main branch, and another test depends on run order and passes alone; Gewerkton says the redesign did not cause these failures, but also did not fix them. The supplied account does not include test logs that would independently verify that explanation.
Other defects were caught by people rather than automated checks. White icon tiles obscured labels in dark mode and were fixed the same evening. Film recoloring also missed red objects in difficult lighting; after review, 24 files were cleaned and 10 regional versions with remaining red were temporarily replaced with the European cut. Nine of those runs were later reshot with Meyer’s approval and visually checked. The account does not explain the final disposition of every affected version.
Film production was paused after round nine when 38 percent of jobs were failing, with 208 of 228 runs completed at that point. The 76 failed jobs were not billed, according to Gewerkton. A wider recoloring attempt also produced rejected results, including blue lips and a blue patch on a face. The supplied source cuts off while discussing project costs after saying film records showed about $134 in actual costs; it gives no complete cost breakdown or basis for comparing that amount with alternatives.
In an Android test on a Pixel 10a, larger type and padding caused camera-screen buttons to break across words. Gewerkton says this was one of five major findings, none considered a blocker, and that all five were scheduled for version 0.5.1. The account does not specify a release date or list the other four findings.
Version 0.5.1 Is the Next Checkpoint
Gewerkton says the five Android findings are scheduled for version 0.5.1, but the supplied account gives no release date. That update is the next stated product milestone. The company also reports that nine regional film versions were reshot after review; it has not provided a full timetable for any remaining film changes.
The account says each film was subject to visual review: the middle frame of each of 157 mirrored films was inspected, and every reworked film was watched at 10, 50 and 90 percent of its length. Further information that would clarify the rollout includes the final status of all regional cuts, the complete cost record, and the outstanding web-test failures. Those details are not provided in the source material.
Key Questions
What did Gewerkton change?
The HORIZON redesign covered its web and phone apps, Studio, all 26 icons and a website with 529 pages in 40 languages. The company also produced 228 regional AI film runs and eight help videos.
Did the redesign start and finish in two days?
Gewerkton says implementation ran on Oct. 2-3, 2026, from an approved plan to the live website. A draft design from Sept. 26 was used as a starting point, so the entire design process did not take only two days.
What did the AI agents do, and what did Meyer control?
According to the publisher, agents implemented the work from written plans in a separate code branch. Thorsten Meyer approved the plan, reviewed and released each part, authorized paid film reruns, and completed Apple’s required agreement step for the iPhone build.
Were all checks and tests successful?
No. Gewerkton reports passing phone-app, Studio and website checks, but also eight web-app test failures it says were not caused by the redesign. Human review found dark-mode icon problems and film recoloring misses; five Android findings are scheduled for version 0.5.1.
How much did the project cost?
The supplied source begins to report about $134 in actual film costs, but the text ends before giving a complete accounting or explaining what the figure includes. It does not provide a full project cost.
