Premed
Which enzyme catalyzes the main rate-limiting step of glycolysis?
You: How do inhibitors change Km and Vmax?
Ion: A competitive inhibitor raises the apparent Km and leaves Vmax unchanged, because enough substrate outcompetes it. A pure non-competitive inhibitor lowers Vmax and leaves Km unchanged.

Study today's plan
Each day you get the reviews about to fade and the practice your next exam needs. Then, when you're ready, your career exam.
Everything you study with, built from your own material.
Ion, your tutor
Ask anything about your course. Ion answers from your own lectures, cites the slide, and speaks your field's language.
Unlimited practice questions
Written in your professor's format and your career exam's, each checked by a second model, and explained five ways.
Flashcards that time themselves
Spaced with FSRS on your own forgetting curve, so each review lands just before you'd forget, and before the exam.
Oral practice
A spoken viva with Ion on your own material, asked the way your field's examiners ask.
Case practice
Work a case as it unfolds: a patient, a client, an incident. Marked against your field's rubric.
Focus and routines
Pomodoro, deep and flow sessions, a deep-work streak, and habits that shape tomorrow's plan.
Calendar sync
A private feed for any calendar app, and two-way sync with Google Calendar and Outlook on Pro and Max.
Offline reviews
Due cards and downloaded questions work with no signal, and sync when you're back.
The same app, all the way to the big one.

Good to know.
Yes. NucHub has a profile for 68 majors and programs, from accounting and architecture to nursing and theatre. Ion, notes and questions are written in your field's own language, and if your field ends in a licensing or admission exam, its formats are built in. Pick "Something else" and it still studies straight from your courses.
From your own lectures, slides, readings and recordings. Every question is checked by a second model that did not write it, plus deterministic checks, before anyone sees it, and every note cites the line it came from. It can still be wrong, so every line is one tap from its source.
On Pro and Max, yes: generate as many as you want, in every format. Free includes 20 practice questions a day, and flashcard reviews are unlimited on every plan.
You move to Free unless you choose a plan. We never asked for a card, so nothing is charged. Your notes, cards and questions stay.
Yes, in the browser on any phone, and it installs to your home screen. Today, your library and practice questions fit small screens, and flashcard reviews keep working offline.
Only you. Files are stored privately and opened only through short-lived links. Deleting a source removes its passages and the file, and the app tells you exactly what goes before anything is removed.
Doors open on Monday 11 January 2027. The first 1,000 people on the list can claim Pro yearly at $129 for their first year, then $149 a year while they stay.
