Have custom GPTs built that know your context.

A custom GPT is the fastest path to an AI assistant that truly masters a clearly scoped task. Instead of explaining the same context to a generic chatbot again and again, you get an assistant that already knows your language, your templates and your rules. We build it with you, connect your knowledge and set it up so anyone on the team can use it from day one. The result is less repetition, faster results and an assistant that fits you.

What a custom GPT is and is not

A custom GPT is a tailored version of a language model equipped with your instructions, your examples and your knowledge.

It knows your proposal language, your tone and your typical tasks.

It is the ideal entry for scoped use cases, like an assistant for proposal text, for support answers or for preparing meetings.

What a custom GPT is not: an agent deeply integrated into your systems that runs complex processes end to end.

Where that is needed, we go a step further to custom AI agents and the company brain.

A custom GPT is often the first, low-cost proof that AI concretely helps you.

What you
gain

You save the constant repetition.

Anyone who has to explain the context to a generic chatbot on every request loses time and gets fluctuating quality. A custom GPT delivers consistent results because your rules are stored for good.

That lowers onboarding, makes results reproducible and takes over routine.

And because everyone on the team uses the same assistant, quality no longer depends on who happens to be operating it. You get a tool that scales your knowledge instead of locking it in individual heads.

Typical use cases

  • A sales team uses a custom GPT that drafts a proposal in your language from a few bullet points.
  • A support team answers requests with an assistant that knows your docs and standard replies.
  • A marketing team creates drafts that follow your brand tone instead of starting from zero.
  • A management team gets structured summaries with action items from meeting notes.
  • These are patterns we build quickly with a common toolstack and that show you real value early.

How we build your custom GPT

  1. We start with the use case that gives you the most, and collect the examples and documents the assistant should know.
  2. We write the instructions so it reliably works in your tone, and connect your knowledge so it answers from your content.
  3. Then we test it on real cases, refine it and onboard you.
  4. On request we build several custom GPTs for different teams and make sure they fit together.
  5. When a case grows beyond a custom GPT, we show the next step.

The difference is consistency. A generic chatbot can do everything a little but nothing reliably in your language. A custom GPT is sharpened for one task and therefore delivers results you can rely on. Add that we build it and onboard you, instead of leaving you alone with an empty input field. That turns a nice gimmick into a tool that saves time and secures quality in daily work.

Frequently asked · 06

Frequently asked questions.

What does a custom GPT cost?
It depends on the use case, the number of sources and the integrations you want. So we do not name a flat price, we clarify in a call what your case needs. We deliberately start lean with a clear use case, so you see value early and the effort stays manageable.
How long does development take?
A first useful custom GPT often stands within days to weeks, depending on your content and wishes. We build iteratively, test on real cases and refine. So you have something in hand quickly and build from there, instead of waiting months for a big result.
Can the custom GPT access our documents?
Yes. That is exactly what makes it useful. We connect your templates, handbooks and standard replies so it answers from your content instead of the general web. On request we build it so your data can stay in Germany or the EU and access is clearly governed.
Does my team need coding skills?
No. We build and set up the custom GPT, you use it. Operation is simple, anyone on the team can work with it right away. If needed we train you so you can maintain instructions and examples yourself and extend the assistant over time.
What if a custom GPT is not enough?
Then we go a step further. When a case needs deep integration or complex flows, we build custom AI agents or a company brain. The custom GPT is often the first proof that AI helps you, and a good starting point from which we expand sensibly.
Is a custom GPT GDPR-aware?
It can be, if built right. We watch for data minimization, clear access and operation that keeps your data in Germany or the EU. Especially with sensitive content, that is decisive. Data protection is part of the build with us, not a later add-on.
