In the digital workshop of modern communication, Loom videos have become the threaded needles stitching together asynchronous collaboration. Yet these visual messages often live precariously on remote servers, subject to link rot, account changes, or platform deprecation. LoomVault Archiver is your dedicated local loom—a sophisticated, browser-integrated preservation engine that captures, organizes, and transforms your Loom recordings into durable, self-contained assets. Think of it as a personal archival library for every face-to-screen moment you've ever shared. Whether you're a project manager preserving client walkthroughs, an educator saving lecture captures, or a creator curating a demo portfolio, this tool ensures your Loom history remains accessible, searchable, and sovereign.

This repository is not a simple scraping tool; it's a thoughtful archival companion. It respects platform integrity while granting you rightful ownership of the content you've created. Every download is handled with metadata preservation, format flexibility, and organizational intelligence.

• Intelligent Content Extraction – Parses Loom page structure to locate the highest-quality video source, handling dynamically loaded content and progressive web app patterns.
• Batch Archival Workflows – Queue multiple recordings from a session, playlist, or search results with a single orchestration command. Think of it as a loom loom, weaving together multiple threads into a single textile.
• Metadata Preservation – Automatically captures title, upload timestamp, creator context, duration, and description. Your archive becomes a searchable database, not just a folder of unsorted clips.
• Adaptive Format Delivery – Choose between original MP4, compressed HEVC for space efficiency, or audio-only M4A for reference playback. No transcoding server needed; processing happens locally on your machine.
• Responsive Dashboard Interface – A lightweight web-based control panel that adapts to any screen size, from ultrawide monitors to tablet-side reference checks. Manage your archive from the browser, in the browser.
• Multilingual Ingestion Support – LoomVault understands content metadata in 12 languages, correctly handling character encoding and date formatting for international teams.
• 24/7 Automated Background Processing – Set up a watch folder or use the browser extension's silent mode. Recordings queued during the day process overnight, ready for your morning review.

Your system should have a modern web browser (Chrome 115+, Firefox 128+, or Edge 120+) with extension support. No server-side installation is required—the entire archival engine operates client-side using WebAssembly and IndexedDB for storage management. The extension occupies approximately 48MB of local storage for its runtime components.

Once the extension is pinned to your toolbar, navigate to any Loom video page. You'll notice a small "Vault Entry" icon overlay appear in the top-right corner of the video player. Clicking it opens the Archival Dashboard—a sliding panel that reveals:

• Current video metadata preview
• Quality options (source / high / medium / audio-only)
• Format choice (MP4 / HEVC / M4A)
• Tag input for multi-dimensional organization
• Destination folder selection (creates a smart-naming structure: ClientName/ProjectName/Date_VideoTitle.mp4)

Select your preferences and click "Secure to Vault". The video begins downloading in the background while you continue browsing. A subtle chime confirms successful archival.

For power users, the Weaver Mode (accessible via the extension popup) allows you to define rules. For example:

• "Download all Loom videos from this Trello board that are newer than 7 days and contain 'sprint review' in the title."
• "Archive every recording shared with me today, organized by sender email domain."

The engine processes these rules using a local pattern-matching engine that never transmits your data externally.

Each component is designed with loose coupling and high cohesion. The extension communicates with the engine via a typed message bus, allowing any part of the system to be swapped or upgraded independently.

The transcoder adapts to your system's capabilities. If it detects an M-series Apple processor, it utilizes hardware-accelerated encoding for HEVC output. On systems with discrete NVIDIA GPUs, NVENC is leveraged for whisper-quiet background conversion. The result is a 60% reduction in file size compared to the original stream with imperceptible quality loss for typical talking-head and screen-share content.

LoomVault correctly interprets date formats from English ("January 15, 2026"), Japanese ("2026年1月15日"), German ("15. Januar 2026"), and nine other locales. Video titles containing right-to-left scripts (Arabic, Hebrew) are stored with proper Unicode bidirectional markers, ensuring file names are universally readable across operating systems.

The dashboard includes a search bar that supports:

• title:"sprint review" – Exact phrase matching
• creator:alice – Filter by creator name or email
• duration:<5min – Short clips only
• date:>2026-01-01 – Recent recordings
• tag:client-x – Custom tag matching

Boolean operators and grouping are supported: (tag:demo OR tag:walkthrough) AND duration:>10min

The vault dashboard provides a health overview:

• Total archived recordings: 1,247
• Storage used: 38.4 GB / 100 GB quota (configurable)
• Deduplication ratio: 1.17x (saved 6.2 GB through intelligent hash matching)
• Pending downloads: 3 (queued for off-peak processing at 02:00 local time)
• Failed archivals: 0 (with 7-day success rate of 99.4%)

LoomVault operates on the principle of local-first sovereignty. Your data never traverses a third-party server. The extraction engine sits inside the browser's extension sandbox, communicating only with Loom's public CDN endpoints to retrieve the video stream you have authorized access to view. This design ensures:

1. Privacy by Architecture – No proxy, no intermediary, no logging of your activities.
2. Security by Isolation – The engine cannot access other websites' data without explicit user interaction on the Loom domain.
3. Resilience by Decentralization – If Loom changes its page structure tomorrow, the extraction selector engine will flag a mismatch and enter a maintenance mode, displaying a diff of the changes for the community to patch. No single point of failure.

The queue manager uses a priority-weighted round-robin algorithm. Videos you explicitly click "Secure to Vault" on receive priority 1 (instant processing). Batch rules and watch folders are processed at priority 2 (opportunistic background). Failed downloads are retried up to three times with exponential backoff (30 seconds, 2 minutes, 10 minutes).

LoomVault Archiver was born from a simple observation: the videos we create today are the documentation our future selves will search for. We build tools that honor that future. Every line of code prioritizes durability, discoverability, and user agency. Your Loom library is not merely a collection of URLs—it's a living archive of decisions, explanations, and human connection. We're here to help you keep it safe.
