How to use this study desk
Open a PDF, select a tool, then write or highlight. Keep page-linked notes beside the document. Download the annotated PDF or an editable project to continue later.
Scanned PDFs allow drawing and area highlights. Text selection, text search and reading aloud require an existing text layer.
Browser sessions are local to this device and can be lost when browser data is cleared. Download an editable project for a portable backup.
Files stay on your device: All PDF parsing, rendering, inking, notes, and PDF export run 100% locally in your browser. Exported PDFs preserve original page vectors and searchable text while stamping your vector ink, highlights, and Unicode/Devanagari notes AND attaching standard PDF /Annots dictionaries.
