Custom GPT & Claude Integrations

We build language models from OpenAI and Anthropic directly into your software, workflows or internal tools.

The problem

Your team copies text back and forth between ChatGPT and your systems, each person with their own prompts and no control over data flow or quality. Results vary, and none of it is connected to how you actually work.

What is included

Use-case analysis and choice of the right model
Prompt design with clear rules for tone, format and limits
API integration into your application, CRM or automation
Structured output (e.g. JSON) ready for further processing
Testing with real examples from your day-to-day work
Cost and usage monitoring
Optional: approval interface so a person reviews results

What you get

Production integration in your system
Versioned prompts and configuration
Test cases with expected outputs
Technical documentation
Overview of data flows and running costs

FAQ

Questions about this service

GPT or Claude: which is better?

It depends on the task. We test both on your examples and recommend whichever fits best on quality, speed and cost. Switching later remains possible.

What are the running costs?

API usage is billed by the provider based on consumption, through your own account. We estimate costs up front based on your volume and build in limits and monitoring.

Does a person stay in control?

Wherever mistakes would matter, we add an approval step: the model suggests, a team member confirms. Uncertain outputs are flagged instead of being silently accepted.
