Built for an industrial company. For confidentiality, the company name, logo, product/part codes and internal data are not shared; images are cropped accordingly. The flow diagram is illustrative.

The need

Finding the right document to answer customers' and dealers' technical questions takes time, and questions outside office hours go unanswered.

The solution

Product documents are chunked into a vector database; the most relevant sections are found per question.
Results are re-ranked and passed to the AI; the answer relies only on the documents.
On the phone channel the question is transcribed and the answer is read in natural Turkish.
Every conversation is logged and, if needed, e-mailed to the right person.
