I've been working on something that directly targets this problem: WFGY — a reasoning engine built for RAG on large-scale PDF/Word documents, especially when you're doing deep research, not just shallow QA.
Instead of just chunking text and throwing it into an embedding model, WFGY builds a persistent semantic resonance layer — meaning it tracks context through formatting breaks, footnotes, diagram captions, even corrupted OCR sections.
The engine applies multiple self-correcting pathways (we call them BBMC and BBPF) so even when parsing is incomplete or wrong, reasoning still holds. That’s crucial if your source materials are academic papers, messy reports, or 1000+ page archives.
It’s open source.
No tuning.
Works with any LLM.
No tricks.
Backed by the creator of tesseract.js (36k) — who gets why document mess is the real challenge.

I spent the last 2 months trying out RAG/parsing plays. My use-case required high accuracy on complex tables and figures.
Ranking: 1. LlamaCloud/LlamaParse 2. GroundX 3. Unstructured.io 4. Google RAG Engine 5. Docling ... capability gap... 6. Azure - Document Intelligence 7. AWS - Textract 8. LlamaIndex (DIY)
This ranking is just for the parsing, not the RAG Portion, correct?
