What movie diary keepers need from IMDb list sync tools

A movie diary keeper records the movies and shows they watch, often as a list on a site like IMDb. Keeping that list working with a Plex server means the titles in it arrive as files Radarr or Sonarr can grab. The jobs are simple: a public list turns into downloads, the list is re-read so new entries appear, and titles reach the right app, movies to Radarr and shows to Sonarr. The limits are just as real. Shows without a TheTVDB id that Watcharr cannot match are left out, and it tells you which ones it skipped. ^[1] How often each tool re-reads a list is set out in its own figures, so compare those. Keepers may keep more than one list, such as a watchlist and a seen-so-far list, and may want them combined into one feed. Owners often set up the tool once and expect it to keep working without constant care. The choice turns on whether the list is public, how often the tool re-reads it, and whether the keeper signs in or wants a no-account option.

Questions to ask before you choose

Before choosing an IMDb list sync tool, ask how the titles reach Radarr and Sonarr, since some tools make that step clear and some do not. Check whether the list must be public or can be private, and how often the list is re-read so a new diary entry appears. Ask whether signing in is required and whether an account is acceptable. Check how the tool handles a title that cannot be matched, and whether it tells you about the ones it left out. Ask whether several lists can be combined and whether a title on two lists is added once. Check the cost, and what a paid option changes. Check the licence if the use is anything other than personal.
