حول هذه الأداة
Prepare PDF for AI turns documents into the JSON shape retrieval pipelines expect: an array of { text, metadata } records compatible with LlamaIndex and LangChain loaders.
Three chunking strategies are available. Per-page keeps citations exact, fixed-size character windows with overlap suit embedding models with a token budget, and whole-document is best for short files. Chunk boundaries prefer sentence breaks so meaning is not cut mid-thought.
Every chunk carries its source file, page number and document metadata, and batches of PDFs come back as a ZIP. Nothing is uploaded anywhere.

Keep page numbers on every chunk so generated answers can cite their source.
الأسئلة المتداولة
Which chunking strategy should I use?
Per-page for citation accuracy, character windows when your embedding model has a strict token limit, whole-document for short files.
Why does overlap matter?
Overlap keeps a sentence that straddles a chunk boundary retrievable from either side, which measurably improves recall.
Does this work on scanned PDFs?
No — it reads the text layer. Run OCR first.
