What It Does

Frankenfile is an AI-powered desktop utility for macOS that automates tedious file manipulation tasks across multiple media types. Simply select your files, describe what you want in plain English, and let the AI handle the technical details. All processing happens locally on your Mac—no files are uploaded to external servers.

Who It's For

Frankenfile is designed for Mac users who regularly work with media files and documents: content creators, photographers, video editors, designers, and knowledge workers who need to batch-process files without learning complex command-line tools or expensive professional software.

Key Features & Capabilities

• Image Processing: Convert between formats (PNG, JPG, GIF), resize, crop, overlay watermarks, generate thumbnails, create circle thumbnails
• Video Editing: Convert formats (MP4, MOV), clip/trim videos, resize, separate audio tracks
• Audio Manipulation: Convert formats (MP3, WAV), trim/cut, compress, split tracks
• PDF Management: Split PDFs by page ranges, merge multiple PDFs, convert to other formats
• Natural Language Control: Describe tasks in plain English instead of learning complex software interfaces
• Privacy-First Design: All processing runs locally on your machine with no cloud uploads

Typical Workflows

Common use cases include batch watermarking product photos, splitting long videos into clips, organizing receipts and expenses by automatically sorting and renaming files, creating social media thumbnails, converting file formats for different platforms, and managing document workflows.

What Makes It Different

Unlike traditional batch processing tools that require learning specific syntax or navigating complex UIs, Frankenfile uses AI to interpret natural language commands. The local-first architecture ensures your files never leave your computer, making it ideal for sensitive content or users concerned about privacy.
