ProofFidget is a puzzle-driven way to learn the feel of doing math: not by memorizing procedures, but by making correct moves, one step at a time, until a proof truly holds together. Each puzzle gives you a clear goal and a partially-complete derivation. You spin the wheel to choose your next move, then commit to a step and watch the proof line up. If you’re right, you progress; if you’re wrong, you learn quickly why it didn’t fit. The result is a tight feedback loop that makes abstract ideas concrete and surprisingly fun. You’ll work across a growing set of subjects, including: Logic and proof techniques: build confidence with implication, contradiction, and structured reasoning. Algebra: make valid transformations while keeping equations balanced, supported by visual “balance scale” diagrams. Number theory: practice modular arithmetic, divisibility, and gcd-style reasoning with intuitive visuals. Geometry and beyond: use diagrams to ground symbolic steps in something you can see. ProofFidget is designed for short, satisfying sessions, but it also rewards deeper play: you start noticing patterns, choosing steps for the right reasons, and developing proof instincts that transfer to real coursework and problem-solving. If you’ve ever thought “I understand the formula, but I don’t understand why,” ProofFidget is built for that moment.

AnswerStep is an AI-powered learning app that helps you solve problems step by step instead of simply showing final answers. Unlike traditional AI answer tools, AnswerStep focuses on the reasoning process. Interactive flows guide you through hints, choices, yes/no questions, input steps, and explanations that help you truly understand how a solution works. Submit your own math, logic, or reading problems and learn privately. Your problems stay in your workspace unless you choose to share a link. Key Features Submit and solve immediately Open AnswerStep and paste or upload a problem right away. Get an AI-generated step-by-step solution without browsing a public problem feed. Step-by-step interactive learning Work through guided solution flows one step at a time instead of passively reading long explanations. Interactive runs Answer questions, reveal hints, track progress, and learn actively while solving problems. AI-powered flow generation Generate structured learning flows for math, logic, and reading problems using advanced AI models. Private by default, share when needed Your submitted problems are visible only to you. Share a link so others can view the problem, open the flow, and run it. Improve and fork flows Fork a solution flow, refine explanations, and keep learning with a clearer path.
