AI-Driven Document Interaction Using Nextcloud and OpenAI

The workflow consists of a main workflow and a sub-workflow. The main workflow initiates with a public chat trigger that engages users and processes their queries using an AI agent. This agent, powered by LangChain and OpenAI, leverages short-term memory to maintain context. When a user inquires about documents, the workflow calls the 'Nextcloud Tool' sub-workflow to retrieve and process document content from specified Nextcloud folders. The sub-workflow filters files by type (PDF, Markdown, DOCX), extracts text, aggregates it, and returns it to the AI agent, enriching the interaction with detailed document insights.
