Checkwerk
5.0Built with AIAI-supported paper-to-digital checklist flow
A team that listens, understands, and delivers.
Working with Vitec felt like true partnership. They took time to understand our concept and shaped it into a polished web experience. Responses were quick and professional, and solutions were prioritized thoughtfully. The end result exceeded what we imagined when we started.

WeGuide
5.0Developed with AITime to market cut by 50 % through AI-supported development
Their workflow is transparent
We are working with Vitec to develop our mobile app for our start-up. What began as an initial project has turned into a long-term partnership that helps our start-up grow every day.
Meal Planner
5.0Built with AIConfigurator-driven recipe logic: weekly plans by family, preferences and allergies
A supportive partner for first-time founders.
As a first-time founder, I needed guidance as much as execution. The collaboration helped me visualize, refine, and finally build a highly personalized meal-planning app from scratch. Changes were handled flexibly, communication stayed open, and deadlines were respected.

Vitec GmbH's development process has been seamless.
Vitec delivered a scalable web and mobile platform that replaced multiple legacy systems and streamlined communication across our entire operation. Their structured approach, speed of execution, and reliability allowed us to move from idea to market without costly rework.

How we make AI reliable
A language model can be wrong. That is why, before we start, we define what it answers from, how we test it and where a person takes over.
Answers from your sources
The AI answers from your documents and data and shows the source for every answer.
Tested before every release
Fixed test cases run automatically with every change. That way we see whether answers get worse before they go live.
A person decides where it matters
If the AI is unsure or an important decision is at stake, your team takes over or approves.
Your data, your rules
We choose model, hosting and data flow to match your data protection requirements. The transparency duties of the EU AI Act are planned in from the start.
Not every problem needs AI
AI in the product pays off where software has to weigh things up. Everything else we build the classic way, developed with AI and therefore faster.

Frequently asked questions about AI development
We use AI to build solutions that do real work in your business: AI chatbots, AI agents, automations and AI in your existing software. From the strategy call to production, everything comes from one team.
It depends on the data, the integration and the number of requests. In the free strategy call we clarify the scope, then you get an estimate including the running cost per request.
The model that fits your task: Claude, GPT (the model behind ChatGPT), Gemini or open-source models. We choose by quality, cost per request and data protection, not by vendor.
Yes, that is often the fastest route, because the data and the users are already there. When your data changes, the AI follows automatically.
An AI chatbot answers questions, for example from your documents. An AI agent also carries out tasks in your systems, such as sorting requests or creating drafts, and where it matters, a person approves.
Workflows in which people read, weigh up and pass on information: sorting requests, checking documents, writing drafts. Where the rules are clear-cut, classic automation without running AI costs is enough.
You describe in plain language what an application should do, and an AI writes the code: ideal for a quick prototype. For production we then continue properly, with architecture, tests and security.
In planning, design, code, tests and reviews, AI takes on the routine work and people make the decisions. At WeGuide this cut the time to market by 50 %.
It only answers from your sources and hands over to a person when it is unsure. Automated test runs catch errors before they repeat.
We choose model, hosting and data flow to match your data protection requirements; parts such as the document search can run locally. Which data the AI may see, we agree together beforehand.
For most applications mainly transparency: users must be able to tell that they are talking to an AI. High-risk areas such as recruitment we plan with the stricter duties from the start.
Where decisions by criteria tie up a lot of time from experienced people, usually yes. Where the rules are clear-cut, classic software developed with AI is often cheaper; we tell you that up front.
Yes. In the free strategy call we clarify where AI takes work off you and where classic software is enough; for larger projects there is our product strategy with a discovery phase.
For a quick test, a freelancer can be enough. If the solution is meant to go into production, with tests, data protection, maintenance and cover within the team, a partner with its own team is the safer choice, and we discuss that honestly in the strategy call.
By real case studies with reviews, by a prototype with your data before the big contract, and by someone who also tells you where AI is not worth it. That is exactly how we work: prototype first, then production, and classic software where it fits better.
Where can AI take work off you?
In the free strategy call we tell you honestly whether AI in the product is the right solution or whether classic software, developed with AI, is the better fit.
