From your first question to your next review.
Work through a reaction, explore a pathway, and build a library of study materials. Take a look inside the tools that bring it together.
AI Tutor Beta
Work through the question in front of you.
Ask questions in general chemistry, organic chemistry, and biochemistry. Attach your course materials for context and explore supported reactions with molecular visuals and explanations.
Reaction Practice
Draw. Check. Refine.
Choose the reaction families you want to practice, draw the product, and check your answer. Use feedback and hints to work through a mismatch, then revise your drawing and try again.
Concept Maps
Visual science for your classes and what comes next.
Explore biology, chemistry, biochemistry, and physiology through interactive concept maps. Whether you’re completing required undergraduate courses, studying nursing, PA studies, or forensic science, preparing for the MCAT, or building toward graduate school, follow the mechanisms and understand why each step happens.

Every Study Session Turns Into A Scavenger Hunt For One Right Answer.
Course materials for the theory. Master Organic Chemistry or Chad’s Prep for extra explanation. YouTube for the visual walkthrough. ChatGPT for a quick check that’s wrong half the time. By the time you’ve cross-referenced everything, you’ve spent more time hunting than learning.
Course Materials
Best materials to study for your class, but often too dense.
Master Organic Chemistry / Chad’s Prep
Great material, but static and can't ask questions.
YouTube
New perspective, but not focused on your materials.
ChatGPT
Confident explanations. Wrong visuals.

Built By Someone Who Was Still Failing To Keep Up.
I’m Reise. I struggled with Organic Chemistry once the reactions started, studying three to five hours on weeknights and five to seven hours on weekends just to keep up. I built a chemistry verification pipeline so I could trust the visuals, then an AI tutor grounded in that same verified chemistry, then reaction practice and study tools built from my own course material. I called it STEMFlow.
The Grade Went From 91% To 100%. The Percentile Went From 85th To 97th.
Reise and five classmates who didn’t know about the tools beforehand all passed Organic Chemistry II and completed the ACS exam.

Reise + 5 early students. 6 of 6 passed Organic Chemistry II and completed the ACS exam.
