Prepare this PDF for AI
AI assistants read PDFs better when the content is clean. This tool restores the reading order, keeps headings, tables and equations, removes repeated headers and page numbers, and gives you text you can paste or index.
What you get
- AI-ready Markdown, ready to copy and paste
- Chunks (JSONL) that never split a table, each tagged with its section and page numbers
- Plain text and structured JSON versions of the same content
- An estimate of the length in tokens
How it works
- The PDF is analysed for structure: sections, tables, lists, figures and equations.
- Multi-column pages are put in reading order, and repeated page furniture is removed.
- The result is written as Markdown with a short source header, plus section-aware chunks for retrieval (RAG) systems.
Good to know
- Nothing is sent to any AI company. Processing happens on our own servers.
- Charts are identified and captioned, but the numbers inside a chart image are not read.
- Scanned pages are read with OCR and marked as such.
Questions
Why not just upload the PDF to the chatbot?
Many assistants extract PDF text naively. Columns get interleaved, tables collapse into lines and footers repeat on every page. Clean input gives better answers and uses fewer tokens.
What are chunks?
Pieces of the document sized for vector databases. Each chunk knows its section path (for example, “Results > Table 2”) and its pages, which helps retrieval and citations.
Is my document used for training?
No. Uploaded documents are never used for training and are deleted automatically.
