Frankenfile
A macOS app that performs local file conversion, media editing, PDF work, sorting, and renaming from plain-language requests.
About Frankenfile
Frankenfile is a macOS utility for recurring file conversion, editing, and organization. Choose a set of files, describe the result in ordinary language, and the app performs the task without requiring a script or several specialist tools. It can create circular image thumbnails, place a watermark over a video, split a PDF into selected page ranges, and sort receipts while renaming them in order. Other supported work includes image conversion, resizing, and cropping; video conversion, trimming, resizing, and audio separation; audio conversion, cutting, compression, and track splitting; plus PDF splitting, merging, and conversion. Processing runs locally, and files are not uploaded. That may suit everyday work with private material, although teams that conduct a formal review should note the lack of a separate privacy or security document. The macOS app costs $19 and includes new features and updates. Users may bring their own LLM or use Frankenfile's service, but its limits and terms are unspecified. Frankenfile fits Mac users who regularly handle mixed file chores and want one natural-language interface. It is not available for Windows or Linux, and regulated organizations may need more security documentation before approving it.

Pros
- The $19 listed price is a one-time, concrete entry cost rather than an advertised recurring subscription.
- Local operation keeps selected files on the Mac according to the official site, reducing upload exposure for routine work.
- One plain-language workflow covers images, video, audio, PDFs, sorting, and renaming, which can replace several manual steps.
Cons
- The advertised app is for macOS, so Windows and Linux users need another workflow.
- Limits and terms for the supplied LLM service are not specified, so usage expectations require confirmation.
- A separate security or privacy document is not available, which may slow approval for regulated teams.
