Yes — Intertitle is free. Every feature currently available to users, on iOS and the web, costs nothing: the Tonight lineup, the Reely film companion (within its daily message cap), Letterboxd import and ongoing sync, the in-app film diary and ratings, and Wrapped.
TL;DR
There's no paywall in Intertitle right now — a few usage caps exist (like Reely's daily message limit), but none of them can be lifted by paying, because there's nothing to buy. A Pro tier is planned for the future, but there's no purchase flow live anywhere in the app today — nobody can buy Pro yet.
What's free today
The Tonight lineup. Import your Letterboxd history or log ratings in-app, and Intertitle returns a short, taste-ranked shortlist for tonight — free.
Reely, the film companion. A conversational companion you can ask "what should I watch tonight?" or talk any film through. It's free within a daily message cap: 35 messages/day if you're signed in, 10/day if you're not.
Letterboxd import and sync. Upload your Letterboxd export once, then connect your Letterboxd handle and Intertitle keeps syncing new diary entries automatically after that — free.
The film diary. Log and rate films directly in Intertitle, no Letterboxd account required — free.
Wrapped and stats. Your watch stats, taste map, and a film-taste archetype (one of 16) — free.
Why there's no Pro to buy yet
Intertitle's codebase has the scaffolding for a future Pro tier, but there is no purchase flow anywhere in the app — no in-app purchase screen, no subscription checkout. Until that ships, describing anything as an "upgrade" or "unlock" would be inaccurate: there's simply nothing to purchase. Everything usable today is the free tier, full stop.
