How does PaperAI preserve tables in PDF-to-text conversion?

The AI identifies table boundaries, column headers, and row structure visually. Tables are output as proper Markdown tables with aligned columns and headers — not as scattered text fragments.

Can I extract text from password-protected PDFs?

PaperAI processes PDFs that you can open and view. If a PDF requires a password to open, you will need to remove the password protection before uploading. Print-restricted PDFs can be processed normally.

What output formats are available?

PaperAI outputs as structured Markdown (preserving headings, tables, and lists), plain text, JSON (with extraction fields), or CSV (for tabular data). Choose the format that fits your downstream workflow.

PDF to text that actually preserves your document's structure.

Q: Does PaperAI handle scanned PDFs or just native digital ones?

PaperAI handles both equally well. Native digital PDFs are processed quickly and accurately. Scanned PDFs are processed using vision AI that reads the page as an image, preserving structure even from low-quality scans.

Traditional PDF-to-text tools produce jumbled paragraphs. PaperAI's AI reads the entire page visually, preserving headings, tables, columns, and lists in the output. Works with both native PDFs and scanned documents.

“Traditional scanning services quoted us 18 months. PaperAI processed the priority collection in 6 weeks.”

PDF-to-text conversion sounds simple, but most tools get it wrong. They extract characters left-to-right, top-to-bottom, ignoring columns, tables, and headers. A two-column document becomes an unreadable mess. A table becomes scattered numbers and words with no structure.

PaperAI takes a fundamentally different approach. Instead of extracting characters, the AI processes each page as an image and reconstructs the document's logical structure. Columns stay separate. Tables retain their rows and columns. Headers are identified as headers. The result is clean, structured text you can actually use.

PaperAI supports 12+ document and image formats and achieves 95%+ accuracy on clean PDFs. Each page processes in under 30 seconds, and the free plan gives you 100 credits to test with your own documents before committing to a paid plan.

How it works

Upload PDFs

Upload native digital PDFs or scanned documents. PaperAI handles single-page and multi-page PDFs, image-based scans, and documents with mixed text and tables.

AI reconstructs structure

Vision AI processes each page as an image, identifying headings, paragraphs, tables, columns, and lists. The AI understands document hierarchy — not just character sequences.

Review side-by-side

Compare the original PDF with the extracted text in the side-by-side view. Confidence scores highlight pages or sections where the AI is less certain about the output.

Export clean text

Download as Markdown (preserving structure), plain text, or JSON. The output is ready for editing, searching, archiving, or feeding into your downstream tools.
