HarmonySync от Arvi

Harmony Sync
Harmony Sync is a lightweight, fully automated Chrome extension that lets you instantly transfer your favorite playlists between major streaming platforms like Spotify, YouTube Music, Apple Music, Tidal, and Deezer.

Stop wasting time manually searching for songs or paying for expensive third-party syncing services. Harmony Sync runs directly in your browser, leveraging a smart matching engine to find and save your tracks across platforms in real-time.

Key Features
Universal Support: Extract your playlists from Spotify, Apple Music, YouTube Music, Tidal, and Deezer, and seamlessly transfer them to your Spotify, Apple Music, or YouTube Music accounts.

Smart Matching Engine: Automatically sanitizes track titles and cross-references artists to ensure the highest possible match accuracy.

Real-Time Tracking: Watch your transfer progress live with a built-in stopwatch, exact song counts, and an accurate ETA.

Auto-Playlist Creation: Automatically generates a newly sequenced playlist in your destination account to keep your library organized.

Frictionless Setup: No third-party accounts, subscriptions, or external dashboard logins required.

How it Works
Open a tab with the source playlist you want to transfer.

Open a second tab for your destination music platform.

Click the Harmony Sync extension icon.

Verify the auto-detected route (e.g., Tidal ➔ YouTube Music) and click Run Transfer.

Privacy & Security First
Harmony Sync operates entirely locally within your browser. Your authentication tokens and playlist data are never routed through, stored on, or analyzed by external developer servers. The extension communicates directly and exclusively with the official APIs of your selected music platforms.
