Assistants for customers and internal teams — answers grounded in your data, docs, and processes.
AI embeddings to find similar products, documents, or records by meaning — not just keywords.
Detecting patterns and text in images — like receipt scanning in the SplitWallet app.
Automatically pull structured data from invoices, forms, and PDFs.

Reviews from companies we built custom software and websites for
“We have a very good experience with Nexelon and can clearly recommend them. They delivered an attendance system set up from the start around our requirements — not a generic off-the-shelf product, but one tailored to how we actually work. Follow-up support is a big plus: their response is always prompt and professional.”

“We used to write delivery notes by hand, which took a lot of time. The team built a printing app for us that makes entry much faster and clearer. The system runs reliably with no outages, and communication during setup was seamless.”
