I built a web-based document comparison tool where all file parsing and diffing happens entirely in the browser.

Think interactive grep for text files, PDFs, DOCXs, etc, but word/token based instead of regex and line based, so you can search across lines easily. Docfd aims to provide good UX via integration with common text editors and PDF viewers, so you can jump directly to a search result with a single key press. --- I originally wrote this tool to help me dig through text/markdown notes, since very often I want to search for a phrase of sorts that may span across multiple lines, but constructing the corresponding multiline regex is a bit painful (especially painful if I want to account…
