About this gig

Your AI is only as good as the documents behind it.


Feed it messy PDFs and scans, and it starts guessing. Worse: it guesses with confidence. I fix the part most chatbots skip, the data.


I turn your documents into a clean knowledge base where every single passage knows where it came from: file, page, source. When something isn't in your files, the answer says so instead of inventing it.


What you receive:

- AI-ready text chunks (JSONL), each linked to its original file and page

- A manifest that traces every chunk back to its source

- A quality report: what was read, what wasn't, and why

- Test questions answered from your files, with sources, plus one trap question to prove nothing is made up


Your files never touch a cloud AI. I process everything locally on my own machine and delete it after delivery, with written confirmation.


Not sure your documents fit? Message me first. If they don't, I'll tell you before you pay. Bigger archive or unusual formats? Ask for a custom offer.


Trained as a mechatronics technician in precision manufacturing. I measure twice.

I build AI systems that answer strictly from your own documents, with the source next to every answer. My background is in mechatronics, with three years in precision manufacturing at Physik Instrumente (PI), so I care about things being correct, not just impressive. I got tired of AI tools that confidently make up numbers, so I built my own system that traces every fact back to its source document. If your documents don't fit a project, I'll tell you before you order. Based in Germany, working with clients worldwide.
