Summaries turn derivations into hand-waving. Study Companion teaches every chapter in full — formulas, assumptions, figures explained — and maps the prerequisite chains that make or break engineering courses.
Statics feeds dynamics feeds vibrations. A concept you half-learned in week three becomes the reason week ten makes no sense. The fix is depth on the fundamentals, not thinner summaries of them.
Summarizers strip the derivation steps that are the actual content
Figures — free-body diagrams, phase plots, circuits — get skipped entirely
Flashcards test recall; engineering exams test applied understanding
The prerequisite chain between chapters stays invisible until it bites
Each section keeps the full chain: what is assumed, what follows, and where the idealization stops holding — the part exam questions probe.
Diagrams are explained, not skipped: what the curve shows, why the arrow points that way, what changes when a parameter moves.
The knowledge map draws the dependency graph across chapters — see what week ten actually rests on before it bites.

Skip chapters you don't need — front matter and indexes are excluded free.
Review the chapter with a focused 5-10 minute recap or a two-host discussion.
Listen to the complete lesson while following the study guide section by section.
Generate audio inside your chapter workspace, preview the available voices, and download each finished lesson.
Concept depth first — your problem sets take it from there
Definitions, formulas, derivation steps, and edge cases — kept intact with page references, not condensed into vibes.
Free-body diagrams, stress-strain curves, circuit topologies — described and taught, in the text and in the audio.
The interactive knowledge map shows which concepts feed which — find the week-three gap behind the week-ten confusion.
Wrong answers are real misconceptions — sign conventions, unit errors, misapplied assumptions. 2 credits per chapter, retakes free.
Ask Your Book resolves "which convention does this text use?" from your actual textbook, with the section and pages cited.
Podcast recaps for the bus ride to the exam hall; full read-along narration when you want every derivation spoken through.
Fair question — a chat window is the obvious first stop. Here is the honest difference when the material is measured in hundreds of pages, not paragraphs.
Formulas and derivations kept in full with the source pages cited — not paraphrased away by a chat summary.
Got a 5-page handout? A chatbot is fine. Study Companion exists for the 300-page reviewer.

Yes — and it keeps them. Chapters are taught in full depth: definitions, formulas, derivation steps, and the assumptions behind them, with references back to the source pages. Nothing gets paraphrased into "and then some math happens."
The AI studies each figure and explains what it shows and why it matters — the setup of a free-body diagram, what a stress-strain curve is doing, how a circuit topology works — as part of the section teaching and the audio.
Yes. PDFs, PowerPoint decks, Word documents, and images all work. Slides are converted and structured into sections the same way textbook chapters are.
Processing costs 1 credit per page with the exact quote shown before you commit — but you select chapters, so a 900-page reference is rarely a 900-credit job. Covering the eight chapters your course uses (say 350 pages) is 350 credits; the Power Pack (500 credits, $39.99) handles that with audio and quizzes included, and the Textbook Pack covers the whole book.
Quiz questions (2 credits per chapter, free retakes) are misconception-based — wrong answers are the classic errors: dropped negative signs, wrong reference frames, misapplied ideal assumptions. They test whether you understand the concepts your problem sets depend on; keep doing problem sets for the mechanics.
