Syncing saved titles starts with choosing the lists that matter, deciding where titles should go, and checking what each tool supports before connecting services.

What you need before you start

Prepare the saved title lists that need to move between services and decide where movies and shows should appear after syncing.

Make a list of the services involved, the types of titles you want to move, and the people who need access to the results.

Check whether the tool you choose accepts the source list type and whether it sends titles to the destination service you use.

Keep the original lists available so changes can be checked if a title does not appear where expected.

Decide whether titles should be combined from several lists or kept separate. A clear plan makes it easier to choose a sync method.

Check whether a tool needs an account, an installed app, or a connection to another service before adding it to the workflow.

Step by step

Pick the saved title lists that should be connected and write down where movies and shows should go.

Check each possible sync method for the list sources and destination services it supports before connecting anything.

Add the chosen lists to the selected tool or copy titles manually if a direct connection is not needed.

Review the first set of synced titles and check that movies and shows appear in the intended place.

Check how the tool handles titles it cannot identify or lists that change later.

Review the update schedule and access settings before relying on the workflow for regular use.

Keep notes about the lists and destinations so future changes are easier to track.

Combine lists only after checking how duplicate titles are handled and whether the result matches the way the library is managed.

Tools that can do it

Watcharr can take one public IMDb list and provide one link for Radarr with the movies and one link for Sonarr with the shows. ^[1] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[1]

Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages. ^[1] A bookmark you click inside Radarr or Sonarr adds the list for you, using that app's API key without sending it anywhere else. ^[1]

Watcharr builds its links from the IMDb list's id, so the same list always gives the same two links. ^[1]

Signed-in Watcharr users can combine several IMDb lists into one Radarr link and one Sonarr link for the whole household, and a title that is on two lists is added only once. ^[1] Watcharr looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it cannot match, and tells you which ones it skipped. ^[1]

Manual copying is another approach when a person wants to move titles without adding a sync tool. Check the time needed for updates and the chance of missing changes.

Common mistakes to avoid

Avoid choosing a sync method before checking which saved title sources it accepts. A workflow can become confusing when the source list and destination do not match.

Avoid skipping review of unmatched titles. Check what a tool does when it cannot identify a movie or show before relying on it.

Avoid connecting accounts or lists without checking what access the tool uses. Review the permissions and decide whether they match the intended workflow.

Avoid assuming every sync method updates in the same way. Check the schedule, refresh behavior, and any limits before choosing a tool.

Avoid combining lists without checking whether duplicate titles are handled in the way you expect.
