Why does every LLM app eventually turn into a data cleanup project?

A developer on Reddit points out a common frustration: setting up the LLM/agent logic is fast, but dealing with real-world documents (OCR, parsing, chunking, metadata, messy PDFs) consumes most of the time.

To bypass this bottleneck, the author is prototyping a solution where users drop in raw files and describe the desired outcome in plain English (e.g., "chunk by section, keep version metadata, output clean JSON for RAG"). The system then autonomously handles the cleanup and structuring. The post sparked active discussion within the community about RAG preprocessing workflows.
