Frankenfile

Frankenfile is a macOS application that acts as an AI assistant for performing file work. It lets users select files and describe tasks in plain English, and then executes those tasks locally on the machine. The app targets users who want help managing and transforming various file types such as images, videos, PDFs, and audio without uploading data externally.

Frankenfile operates by creating a sandbox copy of the user’s files, installing necessary libraries, executing commands to perform the requested task, and resolving any errors encountered. It accepts follow-up instructions to repeat the process from a safe baseline, enabling iterative refinement of results while keeping actions contained within the sandboxed environment.

The tool supports a range of tasks across media types: images for format conversion, resizing, cropping, overlays, and thumbnails; videos for format conversion, clipping, resizing, and audio separation; audio for conversion, trimming, and compression; and documents for splitting, merging, and converting PDFs. It emphasizes local operation and task automation within a controlled workflow.

Frankenfile provides a standalone MacOS app with options to bring your own large language model or use its built-in one. It emphasizes security by not uploading files and by running tasks locally, with updates and new features announced for the Mac app.

Use cases

• Convert the format of images and crop or watermark them for sharing.
• Split or merge PDFs and extract pages as needed.
• Clip, resize, or re-encode videos while handling audio separation.
