TL;DR
Gewerkton says AI coding agents implemented its HORIZON redesign across its apps, Studio, icons and multilingual website on Oct. 2-3, 2026. The publisher says a prior design draft existed, people approved and released each stage, and visual inspection caught problems automated tests missed.
Gewerkton, a construction-site documentation tool built in Iffeldorf, Bavaria, says it replaced the look of its web and phone apps, Studio, icons and website on Oct. 2-3, 2026, using AI coding agents to carry out an approved plan. The company’s account says the two-day period covered execution, not the creation of the design from scratch: an interim draft had been prepared on Sept. 26, and founder Thorsten Meyer reviewed and released each part.
The redesign, named HORIZON, covered a wide set of products and assets. Gewerkton says it moved 281 hard-coded web-app color values into design tokens, retaining 11 exceptions, and restyled 47 cards. Phone app version 0.5.0 for iPhone and Android received the new look, as did the Studio in light and dark modes. All 26 icons were re-rendered in Blender using cobalt and navy.
The website’s 529 pages across 40 languages were updated, including a new opening section featuring product screens. The publisher says 1,583 files were uploaded without an error. It also reports 228 AI film runs for five regions, 222 with a regional version of their own, plus eight help videos. Those figures come from Gewerkton’s project account, published by the same publisher that builds the product.
Meyer directed a fleet of Codex and Claude agents, which implemented written plans on a separate copy of the code and their own branch. The plan recorded open decisions, options and recommendations; Meyer says he approved the recommendations. Parts were not merged or delivered until he released them. Films showing the interface were held until he had reviewed the new look, and paid re-runs required his explicit approval. Apple’s developer agreement also required a human action: only Meyer could accept the latest Program License Agreement blocking the iPhone build.

How AI Agents Helped Gewerkton Reimagine Its Brand In Two Days
Gewerkton says AI agents implemented its HORIZON redesign across apps, Studio, icons and a multilingual website. The two-day window covered execution from an earlier draft, with people approving decisions, inspecting results and releasing each stage.
One identity across a broad product set
Gewerkton is a construction-site documentation tool built in Iffeldorf. Its publisher says the HORIZON relaunch updated the product surfaces and the public-facing brand together.
Color system
Hard-coded values were moved into design tokens, with 11 exceptions remaining. A total of 47 cards were restyled.
iPhone + Android
The new look shipped in phone app version 0.5.0. Gewerkton reports 853 of 853 tests passed.
Light and dark
The Studio interface received the redesign in both appearance modes; the publisher reports 2,158 of 2,158 tests passed.
Re-rendered in Blender
All icons were rendered again using a cobalt and navy palette.
Languages updated
The 529-page site gained a new opening section featuring product screens.
AI film runs
For five regions, 222 runs had their own regional version. The project also included eight help videos.
Tests helped; visual inspection caught more
The project account describes automated checks alongside manual inspection. A dark-mode icon problem escaped tests and was caught when Meyer looked at the interface.
Reported test coverage
Plan changed when contrast fell short
The original cobalt measured 4.38:1 against a light background, below Gewerkton’s stated 4.5:1 working standard under WCAG 2.1 AA. The color was darkened to 4.80:1 before release.
Agents implemented; people directed and released
Codex and Claude agents worked from written plans on a separate copy of the code and their own branch. Meyer says he approved recommendations, reviewed results and released each part.
Plan
Open decisions, options and recommendations were recorded in writing.
Implement
Agents carried out the approved work on a separate branch.
Inspect
People checked the product visually; interface films waited for review.
Release
Meyer released each stage. Paid film re-runs needed his explicit approval.
“Where the plan did not hold up, the deviation was logged and the conservative option taken.” Gewerkton project account
Fast delivery still involved retries and open questions
The timeline is the publisher’s account of execution from an existing draft. It does not establish that another team, product or starting point could match it.
Film work needed cleanup
Production paused after round nine when 38% of jobs were failing. Of 228 runs, 208 were completed; 76 failed jobs were not billed. Rework included 24 cleaned files and nine approved re-shoots.
About $134 reported for films
The source gives one actual figure for films, but does not explain its full scope or provide the total redesign cost, staff time or service costs.
First-party account
Gewerkton is developed by its publisher. There is no independent audit, non-AI comparison or detailed split of agent and human work.
Three milestones remain useful for readers
Confirm whether version 0.5.1, with five Android findings addressed, has shipped.
Clarify the status of remaining film edits and every regional version.
Provide fuller detail on costs and the work included in the reported film figure.
Human Checks Shaped the AI Redesign
The account offers a concrete example of how a company used AI agents for a broad production redesign while retaining human control over decisions and releases. The agents did implementation work from an approved plan, but Meyer remained responsible for approvals, visual review and actions the tools could not take. That distinction matters for readers evaluating claims that AI can independently redesign and ship a complex product.
Gewerkton says the work included automated tests as well as manual inspection. 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, and Studio passed 2,158 of 2,158. Yet a dark-mode icon problem escaped testing and was found by Meyer looking at the interface. The episode shows that passing tests and reviewing the actual product addressed different kinds of risk in this project.
The report also documents limits and rework: some film jobs failed, image edits were rejected, and regional versions needed cleanup. These details temper the headline timeline. The work was completed quickly according to the publisher, but the account does not establish that a comparable redesign would take two days for other teams, products or starting conditions.

A Draft Preceded the Two-Day Sprint
The Oct. 2-3 window began after an interim design draft dated Sept. 26. Gewerkton says that draft was carried into the implementation, so the relaunch’s two-day timing describes execution from an approved plan through the live website, rather than the full period of design work. The product is built by Thorsten Meyer in Iffeldorf, and the source account discloses that Gewerkton is developed by its publisher.
The implementation also included decisions where the plan changed. Gewerkton says its original cobalt color measured 4.38:1 contrast against a light background, below the company’s stated working standard of 4.5:1 under WCAG 2.1 AA. The color was darkened to 4.80:1 instead of being shipped as drafted. The publisher says deviations from the plan were recorded and the more conservative option was chosen.
The source describes a release process rather than an autonomous agent deployment: the agents worked on a separate branch, people inspected results, and Meyer released each stage. It also reports that eight web-app tests failed in seven files; six files failed in the same way on the main branch, while one depended on test order and passed alone. Gewerkton says those failures were not caused by the redesign, but were not fixed by it either.
“The plan listed the open decisions, each with options and a recommendation, and Meyer approved it as recommended.”

Costs and Remaining Issues Need Detail
The source material ends as it begins discussing cost, stating that the project records give one real figure for the films: about $134 actual. It does not provide enough information to establish what that amount includes, whether it covers all film-related work, or the total cost of the redesign, including staff time, software and other services. No full project budget is supplied.
The account is a first-party description from the publisher that builds Gewerkton, not an independent audit. It provides test counts and examples of defects but no external verification, comparison with a non-AI workflow, or detailed time records separating agent work from human work. The report also says five major findings from an Android test were scheduled for version 0.5.1; it does not confirm whether that release has shipped.
Some film problems were addressed through rework. Gewerkton says production paused after round nine when 38 percent of jobs were failing, with 208 of 228 runs completed; the 76 failed jobs were not billed. It says 24 files were cleaned and 10 regional versions with remaining red were temporarily switched to the European cut, after which nine runs were reshot with approval and passed visual review. The source does not fully explain the final status of every film or regional version.

Version 0.5.1 Holds Android Fixes
Gewerkton’s account says the five major findings from testing on a Pixel 10a are scheduled for phone app version 0.5.1, with none classed as a blocker. One reported issue involved camera-screen buttons breaking across words after the redesign increased type size and padding; the German word for cancel wraps onto two lines. The account does not give a release date.
The immediate work described also included further film checks and re-runs. Meyer visually inspected the middle frame of each of 157 mirrored films, then reviewed reworked films at 10%, 50% and 90% of their length. Gewerkton says nine regional runs were later reshot and passed that review. The source does not state whether any additional versions remain to be corrected.
For readers following the launch, the next useful milestones are confirmation of the 0.5.1 release, the status of remaining regional film edits and fuller accounting of the reported project cost. Until those details are available, the two-day claim should be understood as the publisher’s account of the implementation window after an earlier design draft and planning work.
