Apollo personal search

Apollo is a search engine and web crawler to digest your digital footprint. What this means is that you choose what to put in it. When you come across something that looks interesting, be it an article, blog post, website, whatever, you manually add it (with built in systems to make doing so easy). If you always want to pull in data from a certain data source, like your notes or something else, you can do that too. This tackles one of the biggest problems of recall in search engines returning a lot of irrelevant information because with Apollo, the signal to noise ratio is very high. You've chosen exactly what to put in it.
