These tools answer two different questions. JustWatch answers "where can I stream this?" Intertitle answers "what should I watch tonight?" — it reads your Letterboxd history and recommends tonight's film from your actual taste, not the algorithm's guess.
TL;DR
JustWatch is a streaming-availability search engine. Search for any title and it tells you which of 80+ services carry it in your country — streaming, rental, or purchase — filtered to the subscriptions you've entered. It also keeps a unified watchlist across services, notifies you when a tracked title lands on something you subscribe to, and surfaces new arrivals and popular picks. Its core strength is answering a question you already know to ask: "where can I watch [specific title]?"
Intertitle solves a different, harder problem: you have a free evening and no title in mind. Intertitle reads your Letterboxd export — or in-app ratings you've entered directly — builds a taste profile from your history, and returns a short, taste-ranked programme for tonight. The films it surfaces are ranked by how closely they match your actual watching patterns, not by what's trending this week. These are complementary tools for consecutive moments in the same decision loop.

Use them together
The two tools occupy consecutive moments in the same decision loop.
Start with Intertitle. Open the Tonight screen and it returns a programme — a short, taste-ranked shortlist built from your ratings and watch history, with the best match headlined. Mood chips, a freeform mood field, and a runtime filter (Under 100m) let you narrow the shortlist to the evening you actually have. Once you have a film in mind, the question shifts from what to watch to where to watch it.
Switch to JustWatch. Search the title Intertitle surfaced. JustWatch shows which services carry it in your country, filtered to the subscriptions you've already set up — streaming, rental, or purchase. If the film isn't available on anything you subscribe to tonight, go back to the programme and try the next one on the shortlist.
The loop closes. Watch the film, then rate it — in Letterboxd or directly in Intertitle. That rating sharpens the taste profile and improves the next programme. JustWatch stays useful throughout: every recommendation Intertitle generates eventually becomes a "where can I watch this?" query, and JustWatch answers that one better than anything else.
