Can I use the output for a literature review?

Yes, as a working source for searching and note-taking. Cite and verify the original paper rather than the extracted copy.

Does it handle two-column papers?

The parser detects common multi-column layouts and reconstructs reading order, though unusually positioned sidebars or figures can still interrupt it.

Will equations be preserved?

Some text-based symbols may survive, but equation layout is not guaranteed. Check all formulas against the PDF.

Free PDF extractor

No signup. Text PDFs stay on your device.

Browser-first processing

Smart OCR fallback. Scans upload only after local detection confirms OCR is needed.

Private by default. Browser-parsed PDFs and extracted text are never saved. OCR requests are processed without being persisted by Brainy Canvas.

What this PDF extractor does

Academic PDFs are difficult to copy because they combine two-column reading order, section headings, footnotes, equations, citations, figures, and tables. The parser uses page coordinates and font information to produce cleaner Markdown than a simple left-to-right text dump.

Use the result as a searchable literature-review source, a starting point for notes, or input to an AI analysis workflow. Extraction is not peer review: equations, symbols, citations, and table values still need to be checked against the published paper.

Built for privacy

Text-layer PDFs are parsed entirely in your browser. Brainy Canvas does not save your PDF or extracted text. If OCR is required, the scan is sent to the OCR processor for that request, and Brainy Canvas does not persist the PDF or output.
