TopK is an end-to-end solution that turns unstructured documents(PDFs, Images, Markdown, HTML) into reliable context for agents and humans. You can search, explore, and extract relevant information from your documents, all grounded in the source material. We believe that context is a search problem. Agents need relevant data to make the right decision. Without the right context, even the best AI models fall short — garbage in, garbage out.

​
