Well done! I'm taking a course on SAT solvers [1], but it uses some lisp format and lets you input from a richer language (e.g. distinct, if-then-else, plus integers rather than just booleans), so I had to look up the conjunctive normal format in your app. The readme for this repo [2] sent me here [3]. Pretty simple format.
I love how fast your app is!
