Knowledge Management

Obsidian allows you to build your own wiki with Markdown; supports Interpage link and link-tracking as well as advanced search and file attachments; also has built-in file manager and PDF viewer.

PDF Reader & OCR

Foxit Reader is my favorite PDF reader. Fast, lightweight, and free; equipped with advanced search functions (e.g. folder search and search & highlight) and split view (so you can read two parts of the document at once, such as main text and endnotes). For OCR and other advanced features, it costs only $5 per year for students & educators.

Fun fact: There is also a split view feature in Microsoft Word and Excel, so that you don't have to jump between pages all the time.

Xodo PDF is touchscreen friendly, smooth operation, and also free, with support for pen and touch as well as basic page manipulations (rotation, rearranging, deletion, etc.), but the app is a bit more unstable than Adobe Acrobat or Foxit.

PDF-XChange Editor is a free PDF reader and also the only easy-to-use and reliable free OCR option that I can find.

Tesseract is an open-source OCR option for the more technically inclined. See this article to get started. See also OCRmyPDF as a more accessible tool using Tesseract and pytesseract for an example of Python wrapper.
