Why do AI tools struggle with some PDFs?

PDFs store content as positioned elements rather than flowing text. Multi-column layouts, headers/footers repeated on every page, watermarks, and complex formatting can confuse AI text extraction, leading to garbled or out-of-order text. Preparing the PDF cleans these issues before AI processing.

What AI tools does this help with?

Any AI system that processes text from PDFs benefits: ChatGPT, Claude, Gemini, custom RAG pipelines, document understanding models, and text analysis tools. The cleaner the input text, the more accurate the AI output.

Does this extract text or optimize the PDF?

Both options are available. You can output an optimized PDF with cleaned content suitable for AI-based PDF tools, or extract the text as plain text / Markdown for direct input into AI systems.

Is this safe for confidential documents before AI analysis?

Yes. The preparation happens entirely on your device via WebAssembly. Your documents are never uploaded anywhere. This is especially important if you plan to use local AI models where the document should never touch a cloud service.
