Letterboxd is the best place to log and rate films — but it doesn't tell you what to watch tonight. That's the gap Intertitle fills: Intertitle reads your Letterboxd history and recommends tonight's film from your actual taste — not the algorithm's guess.
TL;DR
Letterboxd is a film diary and social network. It excels at keeping a record of what you've watched, letting you rate and review films, and connecting you with other cinephiles. Discovery on Letterboxd is social — you see what friends are watching, trending titles in your network, and similar films on any given film's page. What Letterboxd doesn't do is look at your entire watch history and generate tonight's programme — a short, taste-ranked shortlist of films.
Intertitle does exactly that. It imports your Letterboxd export, builds a taste profile from your ratings, and surfaces the films that fit your actual watching patterns — not the films that are popular this week. The two tools are designed to be used together.

When to use which
Use Letterboxd for its community and diary layer: following friends, reading and writing reviews, building public lists by theme or director, and browsing what cinephiles are watching. Letterboxd has spent over a decade becoming the canonical film social network — its database and social graph are mature, and nothing here replaces that.
Use Intertitle for deciding what to watch — and for thinking a film through. Before you watch, you have a free evening and no idea where to start: Intertitle reads everything you've rated (the films you gave four and five stars, the ones you abandoned, the directors you keep returning to) and returns a short, taste-ranked programme for tonight. After you watch, you can talk the film through with Reely, Intertitle's conversational companion — work out what you actually thought, and Reely can even draft a diary entry and rating from that conversation.
Logging isn't locked to either app. You can log and rate films natively in Intertitle, or keep logging in Letterboxd and let Intertitle sync it: connect your handle once and Intertitle pulls in your new diary entries automatically, every few hours, so your taste profile stays current without re-importing.
And Letterboxd isn't required. It's a great on-ramp if you already have years of logged history — but if you don't, rate a handful of films directly in Intertitle and the recommender warms up the same way. The two tools fit the same loop: decide and reflect with Intertitle, keep your social diary on Letterboxd if you want it, and each new log makes the next programme sharper.
How the taste import works
Letterboxd lets you export your data from Settings → Export Your Data. The export comes as a ZIP (or individual CSVs) containing your diary, ratings, reviews, watched films, and watchlist. Intertitle reads those files and converts them into a taste profile — a representation of the patterns in what you've rated highly across genres, directors, decades, and narrative tones. When you open the recommender, Intertitle scores unwatched films against that profile and returns a short, taste-ranked programme for tonight, led by your best match. There's no quiz, no genre picker, no algorithmic trending list — just your own history, turned into a ranked set of picks.
That import is a one-time setup. From there you can connect your Letterboxd handle so Intertitle keeps your profile current automatically — a background sync pulls in your new diary entries every few hours, so you never have to re-export. And whether you keep logging in Letterboxd or log natively in Intertitle, every new film you add makes the next programme sharper.
