DEVONthink vs Hazel

People searching for "DEVONthink vs Hazel" are usually trying to answer one question: which tool should handle their document mess? The comparison is worth making carefully, because the two applications solve related but distinct problems. DEVONthink is built around retrieval. You import or index documents into one or more databases, then rely on full-text search, tags, groups, annotations, and its classification assistant to find and refile material later. It is a research and reference environment as much as a filing system.

Hazel is built around automation. It installs as a preference pane, watches folders you point it at, and evaluates the rules you have written whenever the contents of those folders change. A rule combines conditions (name patterns, dates, file kind, tags, source URL, text contained in the document) with actions (move, rename, sort into a subfolder, add color labels or tags, run a shell script or AppleScript). Files never leave the normal Finder hierarchy.

That difference shapes the decision. If your problem is "I cannot find anything I saved two years ago," a repository model tends to help. If your problem is "my Downloads and Desktop folders fill up faster than I can sort them," background automation tends to help. Sortio takes a third approach to the same underlying problem: you describe the organization you want in plain language and review a proposed plan before anything moves, across macOS, Windows, and Linux.

DEVONthink works by building databases. When you import a file, a copy is stored inside the database bundle; when you index a folder instead, DEVONthink reads the files where they sit and leaves them in the Finder. Either way, it extracts text, runs OCR on scanned PDFs when that feature is enabled, and builds a search index. Its classification assistant analyzes how you have filed similar documents in the past and proposes destination groups for new items, with related-document suggestions surfaced alongside. Organization is therefore semi-manual: the software proposes, you confirm.

Hazel works by evaluating rules on a schedule and on folder change events. Rules are ordered and can be chained, so one rule can move a file into a subfolder where a second, folder-specific rule picks it up. Conditions can nest with any/all logic, renaming uses token patterns built from dates and matched text, and script actions let advanced users extend behavior well past the built-in options. Hazel also handles housekeeping tasks such as clearing old items from folders and tidying up leftover files from deleted applications.

Sortio replaces rule syntax with a prompt. You point it at a folder, describe the result you want, and Sortio proposes a structure based on filenames and metadata, or on the documents themselves when you turn on content analysis. Content analysis only occurs when you explicitly enable the content sorting toggle. Optional renaming, an activity log, and backups taken before changes mean sorts can be reviewed and reverted. Offline mode processes files locally on your device without cloud connectivity.
