A few good questions.
KemLore serves three audiences: non-chemist professionals in drug discovery (biologists, AI/ML scientists, data scientists, project managers), students preparing for exams or building career-ready skills, and early career chemists looking to sharpen their fundamentals or prepare for interviews.
The full Drug Journey, Level 1 Topics 1–5, the first PK topic, and free calculators. Start exploring without a credit card.
Designed for busy professionals. Real drug examples, dozens of interactive animations, bite-sized 5-10 min lessons. Learn by doing with immediate feedback, not passive reading.
No. Level 1 starts from atoms and bonds, so you can begin with zero chemistry background. If you already have some knowledge, jump straight to the level that matches your experience.
KemLore certificates demonstrate verifiable subject knowledge across medicinal chemistry topics. While not a formal accreditation, they are a concrete signal of self-directed learning that you can add to your CV, LinkedIn, or job applications.
The curriculum covers the same concepts discussed in drug discovery project teams: SAR, ADME, pharmacokinetics, molecular interactions, and compound optimisation. Whether you're preparing for interviews, onboarding into a new role, or working cross-functionally with chemists, KemLore builds the fluency you need.
All 6 levels, over 60 topics, over 1,000 questions with detailed explanations, 100+ scientific animations, full dashboard analytics, streak tracking, and completion certificates. We are actively expanding the curriculum with new topics and levels for Pro users.
Absolutely. Many topics cover applied drug discovery concepts that go beyond traditional chemistry curricula, with real-world case studies and SAR analysis. Use the Test Me feature to quiz yourself across any completed topics.
