-Proxies, sidecars, migration tools, linters, anything where SQL hits a hot path.
+Proxies, sidecars, migration tools, linters, anything where SQL hits a hot path. Also a replacement for every regex that's pretending to parse SQL.
 
 #### Why it exists
 
-Because regex is not a parsing strategy, and neither is patience.
+Because the hardest part of parsing SQL in Python is explaining to Python why you're doing it so often.
 
 Inspired by the original [sqlglot](https://github.com/tobymao/sqlglot), which did the decade-long work of mapping 31+ SQL dialects into an elegant, universal AST. libsqlglot does the comparatively trivial work of compiling it. The algorithm was already O(n), the runtime was O(python).
