Here at Android Police, we love Google Now (and all the associated voice actions), but the natural language could use a bit of sprucing up. If you'd like to try an alternative voice assistant, Indigo may grab your attention on this front. The pitch here is that the app remembers your conversations and can sync those inquiries across devices.
If you ask a question like, "Where can I find Indian food around here?" you'll get a list of results.
