How Filmify Works

Filmify reads public Letterboxd activity and turns repeated taste signals into recommendations and a playlist group. The result is a lightweight interpretation, not a score of a person's taste.

Public data only

The app reads profile details, favorite films, public diary activity, public ratings, tags, and visible film history. It cannot read private profiles, hidden activity, or anything behind a Letterboxd login.

Taste signals

Favorites carry strong weight, while recent watches, rating habits, genre patterns, release-era patterns, and recurring movie moods help shape the profile. Sparse profiles produce less confident results.

Recommendation filtering

Candidate movies are compared against films the profile already appears to know, then filtered toward titles with enough public metadata to explain the match. TMDB data helps normalize titles, years, genres, and popularity signals.

Playlist matching

A profile is mapped to one broad movie-taste group, then linked to a Filmify-owned Spotify playlist for that group. Visitors do not connect a Spotify account and Filmify does not receive visitor Spotify tokens.

Where it can be wrong

A public profile is only a partial record. Missing ratings, private history, unavailable pages, or an unusually narrow recent-watch streak can push a result away from how someone would describe their own taste.
