We've written about Jinni before, but now they've added a very interesting new feature: complete integration with the Netflix API. That means you can semantically search through the Netflix catalog even without visiting Netflix.
You can also discover movies within the Netflix Watch Instantly catalog, add titles to Netflix queue, or even start streaming directly from within Jinni. Additionally, you can import ratings and reviews from Netflix, so that Jinni's recommendation engine has something to base its initial suggestions on. Finally, you can import Netflix rental history, and Jinni will only recommend movies you haven't seen.
If you're a Netflix user, I'm sure that Jinni will definitely be worth your time. It does for movies what Pandora's done for music, and having it work with Netflix is a great practical implementation of the technology.
