Chemistry finally has a tutor that can see the molecule

Draw structures. Push arrows. Predict spectra. Track mastery. One account for general and organic chemistry.

7,000+ practice problems Arrow-pushing, not just A–D ¹H / ¹³C NMR and IR in chat Objective-level mastery

Ask it like you’d ask a TA. Show it like you’d show a whiteboard.

Type a question, draw a structure, or attach a photo of your homework. Orbit answers in context — a short clarification, a focused explanation, or a full tutorial — and can drop an interactive app right into the conversation.

Draw in the chat

Open the molecule drawer and ask “what’s the major product?”

Attach an image

Handwritten mechanisms, textbook figures, spectra.

Follow-up memory

“Why is that the electrophile?” — it remembers the last molecule.

Past answers

Searchable history so last night’s SN2 explanation is still there.

Math that renders

LaTeX for rates, equilibria, and mechanisms.

Apps in the thread

Newman, NMR, Lewis, TLC — launched where you asked.

Try asking

“Show me the NMR of ethyl acetate.” “Load a Newman projection of butane.” “Quiz me on electrophilic aromatic substitution.” “How do I make this from benzene?”

7,000+ problems. Draw, name, push arrows.

Snap quizzes cover organic and general chemistry. Generate a quiz from a topic, drill a weak objective, or jump into a 5-question sprint from the home screen.

Instant feedback with type-specific AI explanations — not a generic “try again.”

A 3D lab that launches inside the chat

When a concept needs to be seen, Orbit opens the right app instead of dumping another paragraph.

Visualization & drawing

  • 2D skeletal editor
  • 3D ball-and-stick / space-fill models
  • Lewis structure builder — practice, scratch, or tutorial, with grading
  • Valence bond lab: hybridize orbitals and overlap them to build CH₄, C₂H₄, H₂O, NH₃…

Stereochemistry

  • Newman projections — staggered, eclipsed, gauche, custom substituents
  • Fischer projections for chiral centers and sugars

General chemistry

  • Interactive periodic table
  • Molar mass, significant figures, equation balancer
  • Constitutional isomer generator
  • Kinetics simulator — concentration vs. time

Lab techniques

  • TLC simulator — lanes, mixtures, Rf
  • Chromatography / HPLC sandbox
  • Mass-spec isotopic patterns (M, M+1)
  • Mechanism sandbox with Check Mechanism

Predict the spectrum. Click the peak. See the atom.

¹H NMR, ¹³C NMR, DEPT-135
FTIR with atom ↔ peak highlighting
Geometry, vibrations, HOMO/LUMO
3D conformer generation
PubChem properties, names, pKa
Forward product prediction
Retrosynthetic routes to a target
Kinetics from a reaction network

Teaching simulations and computational estimates — built for learning, not replacing the instrument room.

Know exactly what to study tonight

Exam-ready isn’t a feeling. My Path maps every chapter objective so you study the gaps, not the whole book again.

Mastery ring

Overall mastery, accuracy, and questions answered.

Day streak

Current streak and personal best.

Chapter progress

Drill into objectives: not started → beginner → mastered.

Study heatmap

See when you actually practiced.

Focus areas

Weak tags plus AI-recommended next steps.

Live class

Join a section with an instructor code.

One access code. A live picture of the class.

Section gradebook with class average
At-risk students and lowest-mastery concept
CSV export
Course tracks mapped to chapters and objectives
Semantic question search to build practice
LMS / LTI launch so quizzes live in the course site

Read it in Learn. Practice it in Orbit.

Learn is the interactive textbook. Orbit is the tutor, the problem set, and the mastery map. Same Google sign-in.
