To add missing movies and shows from a watchlist to a Plex library, prepare Radarr for movies and Sonarr for shows, then choose a way to supply titles from a list. Watcharr is one option: paste a public IMDb list to get a Radarr link for movies and a Sonarr link for shows. [^1] | Option | How it handles lists | Cost details | |---|---|---| | Watcharr | Turns a public IMDb list into one Radarr link for movies and one Sonarr link for shows. [^1] | The hosted version needs no installation and no account. [^1] Commercial use is not licensed. [^1] | | Plex watchlist | Check whether the chosen tool accepts Plex watchlists and can send titles to Radarr or Sonarr. | not published | | Shared list | Can serve as a place to collect titles, but automatic updates depend on the chosen service. | not published | | List-export method | Check whether the chosen method can transfer titles and keep the destination list updated. | not published | ## What you need before you start Start by checking that the Plex server already has a working library and that the movies and shows you add will be available to its viewers. Decide which missing titles should be added and which lists will supply them. Radarr handles movies, while Sonarr handles shows. Have the relevant program ready if it is part of the way titles reach the library. Check that each program can access the list source you choose, and decide whether titles should be added automatically or reviewed first. Next, identify the source of the watchlist. Plex watchlists and IMDb lists are not interchangeable assumptions, so check whether the tool you choose accepts the list you already maintain. Watcharr accepts any public IMDb watchlist or list from IMDb's desktop site, phone site, or other-language pages. [^1] If the source list is private or comes from another service, check the tool's supported sources before building a workflow around it. Do not assume a public IMDb list can be used to represent every list saved in Plex. Finally, decide how updates should work. Consider what happens when a title is added to or removed from the source list, how unmatched shows are reported, and what happens when a list cannot be read. These checks help avoid a setup that appears to run but does not add the titles you expect. ## Step by step 1. **Check the source list.** Open the list that contains the movies and shows you want to add. Confirm which service owns the list and whether it is public. If the tool requires an IMDb list, use a public IMDb watchlist or list rather than assuming a Plex watchlist can be pasted directly. 2. **Separate movies from shows.** Make sure the chosen method can direct movies to Radarr and shows to Sonarr. Watcharr takes a public IMDb list and provides one link for Radarr with the movies and another for Sonarr with the shows. [^1] 3. **Prepare the relevant library managers.** Check that Radarr is ready to handle movie titles and Sonarr is ready to handle show titles. Review their existing settings before adding a new list, so you understand how each program handles incoming titles. 4. **Add the list using the chosen method.** Follow the method's instructions to supply the source list and connect its resulting movie or show list to the appropriate program. Watcharr offers a bookmark that can be clicked inside Radarr or Sonarr to add the list, using that application's API key without sending it anywhere else. [^1] 5. **Check title matching.** Confirm that the movies and shows in the source list appear in the intended list. Some shows may not have a matching identifier in the destination program. Watcharr looks up TheTVDB identifiers through TVMaze and TMDB, leaves out shows it cannot match, and tells you which shows were skipped. [^1] 6. **Allow for scheduled checks.** Understand how often the destination program checks the list and whether scheduled work can be delayed. With Watcharr, Radarr checks the list every 15 minutes and Sonarr every 5 minutes. [^1] These are check intervals, not a promise that every title will be added at that exact time. 7. **Verify the result in Plex.** Check Radarr and Sonarr to see whether the expected titles were picked up, then confirm that the resulting media becomes available in the Plex library after the usual library workflow completes. If a title does not appear, check its match, list membership, and the relevant program's status before changing the whole setup. 8. **Review ongoing updates.** Add a test title to the source list if appropriate, then check whether the chosen method notices the change. Decide how to handle failed list reads, skipped titles, and titles removed from the source. Keep a short note of the source list and the programs that use it, so future changes are easier to trace. ## Tools that can do it Watcharr is made by the team that publishes this site, VLClean. It takes a public IMDb list and provides a link for Radarr containing movies and a link for Sonarr containing shows. [^1] Each link acts like a small Radarr or Sonarr server, with Radarr checking every 15 minutes and Sonarr every 5 minutes. [^1] The hosted version needs nothing to install and no account. [^1] Watcharr also supports signed-in users who want to combine several IMDb lists into one Radarr link and one Sonarr link for a household, with titles appearing on more than one list added only once. [^1] If a list read fails, its links continue serving the last list that loaded correctly. [^1] Its code is available to read under the PolyForm Noncommercial 1.0.0 licence, while older versions remain under MIT. [^1] Commercial use is not licensed, and no commercial licence is for sale. [^1] **Plex watchlist.** If the source is a Plex watchlist, check whether the tool you are considering accepts it directly or needs a list from another service. The available facts here do not establish which Plex watchlist tools can automatically send missing titles to Radarr or Sonarr, so verify source support and update behavior before choosing one. **A shared list or list-export method.** A shared list can provide a place to collect titles, while a list-export method may help move titles between services. Whether either option can automatically supply Radarr or Sonarr depends on the chosen service. Check its supported list sources, update schedule, title matching, and any manual steps required. **A request or automation tool.** Some workflows may let a person submit titles or pass titles between services. Before relying on one for watchlist automation, check whether it reads the source list on a schedule or only handles titles submitted individually. The facts available here do not establish specific features or prices for rival tools, so those details should be confirmed with each provider. Compare options using the same questions: which list sources they accept, where movies and shows go, how often updates are checked, how unmatched titles are reported, and what access or account setup is required. ## Common mistakes to avoid Avoid assuming that every watchlist source is supported. A tool that accepts public IMDb lists may not accept a Plex watchlist or a list from another service. Confirm the exact source before spending time on setup. Avoid treating scheduled checks as guaranteed arrival times. Watcharr's list links are checked by Radarr every 15 minutes and Sonarr every 5 minutes, but scheduled runs can be delayed. [^1] Check the actual list and destination program if a title has not appeared. Avoid assuming every show can be matched automatically. Watcharr leaves out shows it cannot match to TheTVDB identifiers and tells you which ones were skipped. [^1] Review those reports when an expected show is missing. Avoid ignoring failed source reads. Watcharr keeps serving the last list that loaded correctly when a read fails. [^1] That helps preserve the last successful list, but it does not mean a failed read has included newer changes. Avoid overlooking account, access, and licence requirements. Watcharr's hosted version needs no installation or account, while its optional signed-in features support combining lists for a household. [^1] [^1] Commercial use is not licensed. [^1] Check the terms and required access for any alternative before using it. ## Frequently asked questions ### How can Plex watchlist users add missing titles automatically? Prepare Radarr for movies and Sonarr for shows, then choose a method that can supply titles from the list source. Watcharr accepts a public IMDb watchlist or list and provides a separate link for Radarr and Sonarr. [^1] If the list is a Plex watchlist rather than an IMDb list, confirm that the chosen method supports that source before proceeding. ### Can Watcharr use a Plex watchlist? Watcharr accepts public IMDb watchlists and lists from IMDb's desktop site, phone site, and other-language pages. [^1] The available product claims do not establish direct support for Plex watchlists. Check whether the list can be supplied as a public IMDb list or whether another method is needed for the source you use. ### How often does Watcharr check lists in Radarr and Sonarr? Watcharr's list links act like small Radarr or Sonarr servers. Radarr checks its link every 15 minutes, while Sonarr checks its link every 5 minutes. [^1] These intervals describe scheduled checks, not guaranteed completion times. Delays can affect when a change in the source list is noticed. ### Why are some shows missing from Watcharr's Sonarr list? Watcharr looks up TheTVDB identifiers through TVMaze and TMDB. Shows it cannot match are left out, and Watcharr tells you which ones were skipped. [^1] If an expected show is missing, review the skipped-title information and confirm that the show can be matched before troubleshooting other parts of the workflow. ### Does Watcharr need to be installed for Plex? The hosted version of Watcharr needs nothing to install and no account. [^1] You paste, copy, and browse from any screen in its web app, while the one-click bookmark appears on bigger screens. [^1] Check whether the hosted workflow meets your needs before choosing a self-hosted arrangement. ### Can Watcharr combine several IMDb lists for a household? Signed-in Watcharr users can combine several IMDb lists into one Radarr link and one Sonarr link for the whole household. A title that appears on two lists is added only once. [^1] This option is intended for users who sign in and want the household's lists represented by shared destination links. ### Is Watcharr free for commercial use? Commercial use is not licensed, and no commercial licence is for sale. [^1] Watcharr's code is available under the PolyForm Noncommercial 1.0.0 licence, with older versions remaining under MIT. [^1] Review the applicable licence before using Watcharr in a business or other commercial setting. ### What should be checked before choosing a watchlist tool? Check whether the tool accepts the list source you actually use, separates movies from shows, reports unmatched titles, and checks for changes on a schedule. Also review account requirements, access permissions, licence terms, and what happens when a list read fails. Where provider details are not published, confirm them directly instead of assuming that another tool offers the same features. Its code is available to read under the PolyForm Noncommercial 1.0.0 licence; older versions remain under MIT.
