What is Gemster?

Movies, TV shows, anime, video games, books, manga and comics: bring everything you love together in one app. Discover titles that match your tastes, keep track of what you’ve enjoyed and share your favorites.

DISCOVER YOUR NEXT FAVORITE

With Expedition, Gemster uses your tastes to suggest personalized recommendations beyond what’s trending. Your interests span different media: a movie, game or book you love can lead you to something new. Add your ratings to build your profile and help refine your recommendations.

FOLLOW YOUR FAVORITES WITH ECHO

Found something you loved? Start with that title and discover others with similar themes, moods or worlds. Stay with the same medium or explore a different one. Your next favorite might be somewhere you hadn’t thought to look.

FIND SOMETHING TO ENJOY TOGETHER

A movie for tonight? A game to play together? Start a group Expedition: Gemster combines your tastes with your friends’ to suggest titles you could all enjoy. For game nights, find games you can play together on the same screen.

KEEP TRACK OF WHAT YOU LOVE

Keep everything you’ve watched, read or played alongside what you want to discover next. Rate titles, track your progress by episode, volume or page, and log your sessions and the time you spend. Organize your plans into custom lists and look back on your discoveries with monthly and yearly recaps.

SHARE RECOMMENDATIONS AND KEEP THE CONVERSATION GOING

Recommend a title to a friend and talk about it in a private conversation. Share your thoughts, react to messages and hide spoilers. Create collaborative lists and keep track of what you’ve experienced together. You can also send a link to a title to anyone, even if they don’t have a Gemster account, with your rating and a personal message if you choose.

MAKE UP YOUR OWN MIND

Ratings can shape your expectations. Choose to hide external ratings and reveal them whenever you’re ready. Discover first. Decide for yourself.

BRING YOUR HISTORY WITH YOU

You don’t have to start from scratch. Import your data from Letterboxd, Goodreads, MyAnimeList, AniList, Steam, Netflix, Prime Video, TV Time or Plex. You can also import your library or history using Gemster’s CSV format.
