What to Watch Sync от Fifthwye

What to Watch Sync automatically tracks what you watch across popular streaming platforms and keeps your watchlist on whattowatch.fyi up to date — no manual logging required.

How it works

Once connected to your What to Watch account, the extension runs quietly in the background. When you open a show or movie on a supported streaming site, it detects the video, extracts the title and episode information, and syncs your progress in real time.

Features

• Automatic playback tracking across Netflix, Disney+, Max, Prime Video, Plex, and more
• Syncs watch progress, episode completion, and playback position
• Marks episodes as watched when you finish them
• Works across series and movies
• Connects securely to your What to Watch account with a one-click login
• No personal data is stored in the extension — everything syncs to your account

Getting started

1. Install the extension
2. Visit whattowatch.fyi and sign in
3. Click "Connect Extension" in your account settings
4. Start watching — your progress syncs automatically

Your watchlist stays in sync whether you switch devices or platforms.
