Overview
Description

DEVONthink stores PDFs, text files, emails, web pages, images, and spreadsheets in a single searchable database, then uses tags, smart groups, and AI-assisted classification to keep large personal or team archives organized without heavy manual filing. Built-in OCR makes scanned documents fully searchable, and cross-referencing tools let users build a personal wiki linking related notes and files together. Beyond storage, DEVONthink supports smart automation rules, AppleScript, and version tracking for documents that change over time, and syncs across Mac, iPad, and iPhone via DEVONthink To Go. It's a favorite among researchers, writers, and anyone managing large volumes of reference material who wants an alternative to scattered folders or cloud drives.

TagSpaces is an open-source file manager that lets users tag, color-code, and annotate files and folders directly instead of relying on rigid folder hierarchies. It runs fully offline with no account required, and its Pro tier adds Kanban and map perspectives, local AI chat over folders via Ollama, and S3-compatible cloud storage access.
