What Hazel does well
Hazel is focused and mature. If your main job is watching folders and moving, renaming or deleting files based on rules, Hazel may be exactly the tool you need.
Why someone might choose Relay instead
Many workflows start with a file but do not end there. A screenshot may need OCR and a note. A PDF may need renaming and filing. An email may need extracting, summarizing and turning into a reminder. Relay is designed for that wider chain.
Good Relay workflows
Screenshot cleanup
Watch a screenshots folder, rename new captures, file them by project and summarize the context into a note.
Client intake
Process downloaded files, extract useful fields, create reminders and prepare a short summary before you reply.
Weekly admin
Run a scheduled workflow to collect notes, reminders and calendar context into a preparation checklist.
Verdict: keep Hazel in mind for pure folder rules. Use Relay when the folder rule needs to become a fuller Mac workflow.
