MolecuLens vs Set Theory Foundations

Explore molecules in 3D, learn chemistry faster, and generate shareable figures with help from AI. MolecuLens gives you access to 100M+ compounds from PubChem. Search by name, SMILES, formula, or even draw — then explore interactive 2D/3D structures in seconds. VISUALIZE & EXPLORE • Interactive 2D and 3D molecular viewing • Highlight functional groups, rings, and key regions with Lens mode • Native support for transition metal complexes (11 metals, 5+ geometries) • Conformer generation for molecules without existing 3D structures AI-POWERED LEARNING • Generate guided molecular tours with AI narration • Create quizzes grounded in molecular analytics • Turn structures into stories for teaching and communication SEARCH ANY WAY YOU WANT • Common names: "caffeine", "aspirin", "glucose" • SMILES strings: paste any valid structure • Coordination notation: "[Fe(H2O)6]3+" • Chemical formulas and PubChem CIDs BUILT FOR EDUCATION Great for organic chemistry students, biochem learners, educators, and science communicators. Build intuition by interacting with structures — not memorizing them.

Set Theory Foundations is an independent study app for learners who want focused practice in core set theory ideas, proof habits, and common reasoning patterns. It is built for beginners, students reviewing discrete math, interview prep learners, and anyone strengthening mathematical logic skills. Practice across four focused categories: - Fundamentals - Practical Skills - Common Pitfalls - Advanced Concepts Features include: - 160 practice questions - Every question includes an explanation - FSRS spaced-repetition intervals to review at the right time - Weak-point heatmap to show what needs work - Daily challenge for steady progress - Mock exams for timed review - Offline practice with no login required Use short sessions to drill definitions, operations, relations, functions, cardinality, proof techniques, and tricky edge cases. Review missed questions, track weak areas, and build confidence before class, exams, or self-study milestones. Practice offline, no login required.
