Seraphic Forge is a cross-platform, AI-enhanced multimedia extraction engine that reimagines how you capture, archive, and transform online video content. Inspired by the principles behind Catalyst (a Tauri-based yt-dlp wrapper), Seraphic Forge takes the concept of video downloading and elevates it into a complete digital fabrication studio—one that intelligently extracts, remixes, and optimizes content for any context, from personal archives to professional production pipelines.

"Not just a downloader. A forge for raw digital ore."

In an era where streaming platforms dominate, the ability to own, organize, and repurpose your media is increasingly rare. Seraphic Forge bridges this gap by providing a secure, elegant, and modular desktop application that does more than simply fetch files. It understands the content it handles, enriches metadata automatically, and adapts output formats based on your target use case—whether you're building a local media server, creating offline study materials, or archiving time-sensitive broadcasts.

Built with Rust and Tauri for the core framework, Seraphic Forge combines the raw speed of a native application with the flexibility of yt-dlp's extensive parsing capabilities. The result: a tool that feels like an extension of your own digital intuition.

• Intelligent Format Adaptation – Seraphic Forge automatically detects the optimal combination of video codec, audio bitrate, and container format based on the source URL and your stated output preference. No more guesswork between MP4, MKV, or WebM.

• Smart Metadata Weaving – Beyond mere filenames, the forge embeds rich metadata (title, author, upload date, description, chapters, and subtitles) directly into the output file. Compatible with Plex, Jellyfin, Kodi, and other media organization tools.

• Subtitle & Caption Fusion – Download and permanently burn-in or sidecar captions in over 50 languages. Perfect for language learners, accessibility creation, or localized archival.

• Playlist & Channel Harvesting – Recursively process entire playlists, channels, or user uploads with intelligent deduplication and automatic naming conventions. Ideal for backing up educational series or music discographies.

• Responsive Architecture – Seraphic Forge adapts seamlessly to Windows, macOS, and Linux desktops, with a UI that resizes gracefully and supports high-DPI, touch, and keyboard-only workflows.

• Multilingual Interface – Available in 12 languages, with community-contributed translations actively maintained. Set your session language independently of system locale.

• 24/7 Processing Queue – The forge's background queue monitors your pending tasks, resumes interrupted downloads after network drops, and can schedule operations during off-peak hours to optimize bandwidth usage.

• Privacy-First Design – Zero telemetry, no cloud dependency, and all processing occurs entirely on your local machine. Your download history never leaves the forge.

Seraphic Forge is built on a three-layer design:

1. The Anvil (Core Engine) – Written in Rust, this layer handles all I/O, networking, and format negotiation with remote servers. It communicates with yt-dlp via a managed subprocess module, ensuring stability even under heavy load.

2. The Hammer (Controller) – The Tauri backend orchestrates URL parsing, queue management, progress tracking, and error recovery. It maintains a persistent job database using SQLite, enabling full session persistence across application restarts.

3. The Crucible (User Interface) – A reactive frontend built with Yew (WebAssembly) communicates with the backend via Tauri's event system. The UI is designed for clarity: minimal clutter, maximum information density.

This separation ensures that even if the UI becomes unresponsive (due to extreme system resource pressure), the background extraction continues uninterrupted. The forge never drops a job.

• Desktop Operating Systems: Windows 10/11, macOS 12+, Linux (glibc 2.28+, all major distributions)
• CPU Architecture: x86_64, ARM64 (Apple Silicon & Raspberry Pi 4/5)
• Minimum RAM: 512 MB (recommended 2 GB for playlist processing)
• Storage: 200 MB application footprint + variable cache (configurable)
• Network: Broadband connection recommended; works on metered connections with bandwidth limit settings
