Custom development · open source AI in the Java stack

AI where it takes work off people — not as an add-on product.

Suggestions, classification, document processing: built into your application with Spring AI or LangChain4j. Models run entirely at your site if you want.

WHY AI BELONGS IN THE APPLICATION

A separate AI tool means a context switch, and context switches get avoided. AI becomes useful when it appears in the work step itself: the suggestion sits in the form, classification happens on upload. With open libraries in the Java or Go stack it stays part of your application — not a foreign body.

How we proceed

1

Scope the use case

One concrete step that costs time today and has clear criteria. Not a chatbot for everything, but a function that measurably relieves work.

2

Connect the knowledge

Your documents and data become searchable via pgvector or OpenSearch. Answers come with a source, not from the model's memory.

3

Build in, not bolt on

Spring AI or LangChain4j integrates the model into your business logic. Permissions, logging and error handling follow the same rules as everything else.

4

Set the limits

What the model may do is in the code. Automated tests check quality and unwanted output before a change goes live.

WHAT THIS ACTUALLY DELIVERS
In-house

if needed: open models on your own hardware, your data stays with you.

With source

instead of from the gut: every answer shows what it came from.

Part of the app

not beside it: AI follows the same permissions and logs as your domain logic.

Technologies

All open source — no licence costs, no lock-in.
