Enter two public Letterboxd usernames. BlendTwo reads both watch diaries and forges one shareable card: your compatibility %, the films you both loved, and how closely your ratings agree. No sign-up, no trackers.
BlendTwo reads each person's public Letterboxd RSS — recent films and ratings. Nothing private, no login, no scraping of anything that isn't already a public feed.
The same two usernames always produce the same card: overlap of films seen, plus how closely you rated the ones you both watched.
Low overlap isn't a bad score — it's "adventurous opposites" with the best films to recommend each other. The card is made to be shared, by both of you.
No analytics, no cookies, no accounts. The card is just an SVG at a stable URL, computed from the two usernames.
