Help Studio

Hello, we have plenty of AI units and would like to create a chatbot that allows user to upload a PDF and asks questions about it (sending the prompts using genai activities). We have this tool developed using langchain using openai API but it’s not cost effective as we could’ve used AI units in UiPath. has anyone done this before in UiPath? it needs to have the component of embedding creation and vector search functions as our PDFs can be very long. I see new activities in UiPath for embedding and similarity search but am clueless how to use them. would really appreciate any help. thanks in advance

Thank you, that’s a new activity I’ve never heard of and it’s nice to know. Any suggestion how to put together of embeddings and similarity search piece? I see these two activities but don’t know how they work. A sample workflow would be really appreciated.
