Your Letterboxd diary is a precise record of your taste — but Letterboxd won't turn it into recommendations. Here's how to do that: export your data and import it into Intertitle, which reads your Letterboxd history and recommends tonight's film from your actual taste — not the algorithm's guess.
Why Your Letterboxd History Is Good Recommendation Fuel
Letterboxd is a film diary — thousands of considered opinions, logged over years. Even a few hundred rated films gives a recommender enough signal to distinguish your taste with real precision: the gap between someone who rates slow-burn arthouse films five stars and someone who rates blockbusters five stars is wide and measurable.
What Letterboxd doesn't do is close the loop. It surfaces community activity, popular lists, and friends' logs — but there's no engine inside Letterboxd that reads your ratings and returns films you haven't seen yet, ranked by how well they fit what you love. Your diary is fuel with nowhere to go.
Intertitle is built for exactly that gap. It reads your Letterboxd data and builds a taste profile from it. What it returns isn't an endless ranked queue: it's a short programme for tonight — a handful of films, taste-ranked, with your strongest match headlined. Decisive, not overwhelming.
Step 1: Export Your Data From Letterboxd
Letterboxd lets you download your full history in a few clicks:
- Log in to Letterboxd on the web.
- Go to Settings → Export Your Data.
- Letterboxd will generate your export and email you a download link. This can take a few minutes.
- Download the ZIP file. It contains individual CSVs:
diary.csv,ratings.csv,reviews.csv,watched.csv, andwatchlist.csv.
You don't need to unzip anything before importing — Intertitle accepts the ZIP directly. If you only want to bring in part of your history, you can upload individual CSVs instead.
Step 2: Import Into Intertitle
- Open Intertitle on iOS (available free on the App Store).
- Sign in or create a free account.
- Find the import option in your profile settings and choose Letterboxd.
- Upload your ZIP file (or any of the individual CSVs).
Intertitle parses your diary, ratings, reviews, watched history, and watchlist, and builds your taste profile from them.
Once the import is done, your taste profile is built immediately and the Tonight screen reflects it on your next visit.
Keep it in sync. The upload is a one-time setup — but you can also connect your Letterboxd handle so Intertitle pulls in your new diary entries automatically, every few hours, with no re-export. Or log films natively in Intertitle. Either way, your taste profile stays current as you keep watching.
No Letterboxd account required. If you're not on Letterboxd, you can rate films directly in Intertitle instead — the engine warms up from in-app ratings the same way. Letterboxd is a great head start if you already have one, not a prerequisite.
Step 3: Get Your Programme for Tonight
Head to the Tonight screen. Intertitle shows a short, taste-ranked programme: one film headlined as your strongest match, followed by a handful of alternatives — the screen labels it "Programmed from your taste."
This is your taste profile matched against films you haven't seen, surfacing the closest matches first. It's a short list by design — not a 200-item queue.
You can narrow it further. Mood chips and a freeform mood field let you specify the register you're in tonight. There's also an "Under 100 minutes" runtime filter when you want something you can actually finish. Or open Reely — Intertitle's conversational film companion — for something more targeted: "something great under 100 minutes" or "a film like Three Colors: Blue but I haven't seen it."
What Intertitle Does With Your Data
When you import your Letterboxd history, Intertitle builds a taste embedding — a vector representation of your preferences in a high-dimensional space. Films that share the qualities you rate highly end up geometrically close to your position; films that don't end up far away. Your ratings weight the profile directly: high ratings pull the vector toward those films' qualities, low ratings push it away, and recency decay means what you've been watching lately influences tonight's programme more than what you logged five years ago.
The primary signal is embedding-based cosine proximity to your taste profile, blended with quality and diversity signals to keep the programme from becoming a narrowing echo chamber. For the full picture of how this works — and why it captures texture and tone that genre tags miss — see How Embedding-Based Recommendations Read Your Film Taste.
The Difference From Keeping It All on Letterboxd
Letterboxd is a community built around logging and discovery — a social graph, reviews, curated lists. It's excellent at what it does. Intertitle is built for the specific moment when you want to know what to watch tonight, without spending twenty minutes scrolling.
They're complementary. Your Letterboxd diary is the input; Intertitle's programme is the output. For a detailed side-by-side of what each does well, where they overlap, and when to use which, see Intertitle vs Letterboxd.
