2Check input impedance
3Verify with the ideal op-amp rules
✓ Full worked solution — every step explained

Practice like it's the real thing

Full-length, exam-difficulty papers with worked solutions — not trivia. Built from yourcourse, so question 7 can't surprise you.

Master the method

Step sheets turn every problem class into a repeatable recipe — prerequisites, ordered steps, and the mistakes that cost everyone marks.

Interview prep

It even interviews you.

Practice behavioral and technical questions out loud with an AI interviewer that knows engineering roles — then get honest, structured feedback before the real thing.

Try a mock interview

Students don't sugarcoat.

Real feedback, straight from the app.

Common questions

Quick answers to what students ask most.

What is Crameleon and how does it work?

Crameleon is an all-in-one study and career dashboard built for engineering students. One account gives you AI practice exams, flashcards, a photo snap-solver, GPA and grade tools, an internship scanner, an AI mock interviewer, interactive simulations, and career guides — everything to get through your degree and land the job. Each tool is purpose-built: upload your course materials and it generates a realistic practice exam with full step-by-step solutions; snap a photo of a problem and it walks you through it. It works for any university or high school course, with an engineering focus.

What tools do I get with one account?

The whole toolkit: an AI practice-exam generator with full solutions, flashcards with spaced repetition, a photo snap-solver, GPA and grade calculators, an internship scanner plus an application tracker, an AI mock interviewer, interactive engineering simulations, step-by-step method sheets, and the engineering career guides. Pick what you need — most students start with the practice exams or the snap solver, then use the career tools when internship season hits.

What are the engineering career guides?

Two short, no-BS e-guides for engineering students. Pick Your Engineering Major breaks down the real salary, job outlook, and honest day-to-day behind every major. The Engineering Career Playbook covers landing the internship, then the job — résumé, timing, interviews, networking, and negotiating the offer. They're $10 each or $15 for both, and every purchase comes with a free month of Crameleon. Find them at crameleon.com/books.

Is Crameleon free to use?

Yes — a free tier with no credit card required: a practice exam with full solutions, flashcards, snap solves, study-chat messages, the GPA tools, the internship scanner, and saved history. Try the whole toolkit before you upgrade.

Student is $9.99/month ($59.99/year) and Pro is $19.99/month ($99.99/year). Both unlock premium research-backed AI generation and higher monthly limits across all the tools — exams, snaps, flashcards, study chat, mock interviews, and more.
