Pairwise · Head-to-head · Personal canon
Head-to-head movie ranking for films you've already seen
Star ratings tell you how much you liked a movie. Canonova uses pairwise comparisons so you can see where each film belongs in your personal canon—an evolving Canonova Score, not another 5-star pile.
Import from Letterboxd or IMDb, then rank head-to-head. It isn't a diary, a critic aggregate, or a recommendation engine—it's a ranking layer on ratings you already have.
What is head-to-head movie ranking?
Most film sites help you log, rate, or discover movies. Pairwise ranking answers a different question: when two films you like sit next to each other, which one do you actually prefer—and how does that reshape your full ranked list?
- Ratings sites capture how much you liked something on a scale.
- Review aggregators summarize other people's opinions.
- Recommendation tools suggest what to watch next.
- Canonova builds your personal ranking from pairwise choices.
How it works
- Import ratings you already made (Letterboxd or IMDb CSV)—a starting point, not a replacement for those libraries.
- Compare any two films head-to-head, or Battle one film through 10 challengers. Each pick updates scores.
- Watch scores move. Canonova Score (Elo-inspired) rises and falls with each outcome; tiers organize the result.
Over time you get a living canon—more precise than stars alone, because humans are better at relative choices than absolute ratings.

Keep your diary where it is. Upload a Letterboxd or IMDb CSV, then use head-to-head picks until your personal movie canon is clearer than a stack of similar star ratings.
