Smart grading without the frustration.
Traditional flashcard apps grade by rigid character-by-character matching. PuduFlash evaluates actual equivalence so you can focus on learning concepts.
(x + 1)^2x^2 + 2x + 1Fails because the characters don't match character-by-character, despite being mathematically identical.
(x + 1)^2x^2 + 2x + 1Recognizes algebraic and symbolic equivalence automatically. No penalty for phrasing or term reordering.
