Ask HN: A tool for writing English that checks “popularity” of used sentences?

As a non-native English speaker I find that the best way to check grammar is to google whole parts of sentences (in apostrophes - exact match). It's because there are multiple exceptions to language rules and some wording just can feel "not right" despite being correct.

Is there a tool that does something like this automatically?

I thought about writing such tool by myself, but it seems there are no good-quality, free search engine APIs that allow many calls. Or, maybe there are some open APIs to book dumps or something similar?
