Windows/Chrome: When you're trying to find a movie to watch, you'll often look it up on IMDB, then read about it on Wikipedia, then go in search of a copy. Portitle puts all of this info in one place, and is accessible from your right-click menu.
Portitle works on Chrome and Windows, and both flavours do essentially the same thing. Just right -click on a movie file, or highlight its name in Chrome and right click, and send it to Portitle. The service will attempt to detect the movie, then give you links to lots of different services to augment your experience.
You'll get direct access to the obvious sourceslike Rotten Tomatoes and IMDB, but also to various services to download and watch the movie, both legitimate and nefarious. If you already have the film on your computer, Portitle even offers direct download links for subtitles from various sources.
Portitle isn't finding anything you couldn't find yourself, but it's nice to have it all collected in one place.
