What's coming

Everything Gemster
will change for you

Smart recommendations, tracking your journey and sharing with friends: everything your cultural life was missing.

Recommendations tailored to you

Gemster's proprietary algorithm goes far beyond popularity rankings. It carefully analyzes your real affinities, cross-references your tastes and dares to surface what you'd never have searched for yourself.

✦ Cross-media recommendations (movies, books, series...)
✦ Refined with every title you add
✦ Focused on discovery, not repetition

Your cultural journal

Centralize your entire cultural life in one place. Add, organize, track, and never lose that title someone recommended six months ago.

✦ Movies, series, books, manga, games...
✦ Lists: "To watch", "In progress", "Top 2026"...
✦ Progress tracking & advanced statistics

Culture together

Share, explore, experience together. Gemster turns every title into a bridge between you and the people you care about, in the same room or not.

✦ Collaborative lists with friends
✦ "Works companion" : link a moment to someone
✦ Recommandations among friends

The thing that changes everything

You'll finally know
what to watch.

Gemster doesn't push the trending charts or the same recs everyone else gets. Gemster actually digs into what you love so it can suggest a movie, a show, a manga, a game or a book that really fits your taste.
