  A hundred-page PDF will render a hundred thumbnails simultaneously and freeze your sidebar if you let it. PDF.js's built-in PDFThumbnailViewer handles caching and navigation for you, or build custom canvases with lazy loading and render cancellation.

  A benchmark you can't reproduce is a marketing claim wearing a lab coat. Nutrient ran the public, 200-document opendataloader-bench corpus and published the full results, including where docling beats it on table structure.

  Chat with your PDF is RAG in a trench coat: extract, chunk, embed, retrieve, answer. The demo looks great on a clean document and falls apart on a scanned page or a flattened table, because the model only answers from what extraction actually pulled out.

  Your users' highlights and sticky notes live in your database, not the PDF, until someone hits download and expects them baked in. annotpdf writes app annotations into the PDF binary as real spec-compliant highlight, square, and text annotations.
