“Construction projects require thousands of documents to be accessed and processed – from BIM models to inventory tracking for supply chain to daily & monthly reports. The problem is that this data is relatively unstructured and is often located in multiple cloud drives, making it difficult to find project information quickly and accurately. After adding Nuclia as our centralized search, our customers can search, retrieve & action specific information quickly & accurately whether that is a PDF document, video, or geometric design data.”

“As a large university, we have terabytes of lecture videos, audio interviews and research papers. We had a huge discoverability problem, and Nuclia solved that. Everything is now indexed and findable, helping our students and employees every day.”

“At Wuolah we manage millions of documents, and thanks to our impressive community, in addition, every month we grow by more than 100 thousand new documents. Indexing those files in an optimal and efficient way, ensuring their quality and at the same time guaranteeing that they comply with our internal and legal regulations, was a real challenge. With Nuclia we can index all the content from documents, including the images they contain, in a simple and fast way, helping us not only to improve the quality of our content, but also to comply with the legal regulations that we have with our strategic partners."
