About Jotdown
Jotdown is an offline document manager and PDF reader for organizing and annotating research documents. It extracts embedded text from PDFs and can use OCR to recognize text in scanned pages. Users can add sticky-note annotations and vector drawings, including stylus input with palm rejection. Documents can be organized in local folders, and an offline Portuguese–English dictionary is included. The app can generate academic citations, including in ABNT format, and export annotated or organized work as Markdown, text, or PDF. Local ZIP backups support backup and restore. A dark theme is available. Jotdown works offline for reading, annotating, and organizing; network access is used only for optional DOI citation import and dictionary downloads. The product states that data stays on the device beyond those optional operations and that no account is required. Jotdown is intended for students, researchers, and academics who need a private way to read, annotate, and organize documents. The available information does not specify OCR accuracy, supported PDF features, or the scope of citation metadata. Its central workflow combines text extraction, annotations, academic references, and local document management.
