Everything it does

Renaming

  • Find & replace (regex too)
  • Add text at the start, end or anywhere
  • Remove words or characters
  • Change case: Title, Sentence, lower, UPPER, camelCase, kebab-case, snake_case
  • Numbering: 001, 002… sorted by name, date or size
  • Date stamps from date taken, created, modified or today
  • Fix extensions (.JPEG → .jpg)
  • One-click clean-up: removes junk like (Official Video), [320kbps], website names, emoji and double spaces
  • Templates from file details: artist, title, BPM, Camelot key, album, date, camera, duration and more

Safety

  • Live before → after preview
  • Name clashes caught and fixed with (2), (3) automatically
  • Full undo and History
  • Copy or move to a new folder instead, so your originals stay untouched

Smart extras

  • RAW + JPG (and video + subtitles) are renamed together
  • Includes files in subfolders
  • Filter by images, audio, video or documents
  • Save your favourite setups as presets
  • Drag and drop onto the window or the Dock icon

AI (optional)

  • Understands everyday commands offline, for free
  • Works with Apple Intelligence, Ollama, Claude or OpenAI for tricky instructions
  • The AI only suggests rules. It never touches your files.
  • Turn AI off completely if you prefer
