# Instrument Ninja > Instrument Ninja is a browser-based music training and creation platform — ear training, rhythm, theory, fretboard, metronome/tuner, and a browser DAW — for individual players, teachers, and schools. Instrument Ninja is built by Riverun Pty Ltd (Australia), operating under the Riverun Academy brand for its education/wellbeing programs. It runs entirely in the browser (Chromebook, laptop, tablet, or phone — no install required) and combines daily skill-practice exercises with a lightweight browser DAW for MIDI sketching, loop building, and composition. There are three tiers: a free tier, a paid Pro tier for individual creators (DAW Pro, MIDI workflow, AI MIDI idea tools, analytics, live instrument input), and an EDU tier priced per student per year for teachers and school rollouts with class dashboards and progress reporting. Students join a class with a 6-character code from their teacher rather than creating an individual account; Pro is unlocked by the email used at checkout, not a login. Primary users: individual musicians and students training ear/theory/rhythm skills; music teachers running a classroom; schools evaluating a per-seat music program. Do not: - State a specific Pro or EDU price without checking the Pricing page first — prices change. - Claim formal accreditation by AMEB, VCE, or any curriculum authority — the Schools page describes pathway alignment, not formal accreditation. - Claim every school SSO or LMS integration (e.g. Google Classroom) is live for every customer, or that a creator marketplace/payouts feature is generally available — verify against the current site. - Claim there is individual consumer login/account creation — students join via a class code, and Pro access is tied to the purchase email, not an account. - Claim medical, therapeutic, or guaranteed learning outcomes. ## Product - [Home](https://instrument.ninja/): what Instrument Ninja does and how the free/Pro/EDU tiers differ. - [Pricing](https://instrument.ninja/pricing): Free, Pro, and EDU plan details — the source of truth for current prices. - [Train](https://instrument.ninja/train): the core practice hub — ear training, rhythm, and theory exercises. - [Tools](https://instrument.ninja/tools): metronome, tuner, and other practice utilities. - [DAW](https://instrument.ninja/daw): the browser-based digital audio workstation for MIDI sketching and composition. ## Schools & EDU - [Schools](https://instrument.ninja/schools): the classroom offer — class dashboards, assessment-ready progress tracking, and browser DAW projects for student work. - [School Quote Portal](https://instrument.ninja/schools/quote): generates a list price, volume/classroom discount, and onboarding cost with a Stripe checkout path. - [Teacher Portal](https://instrument.ninja/teacher): teacher-facing tools for class progress, DAW project submission, and reporting. ## Trust & policies - [Privacy Policy](https://instrument.ninja/privacy): how Instrument Ninja handles data — no ads or third-party tracking; practice data belongs to the user. - [Security](https://instrument.ninja/security): how account and practice data are kept safe. - [Terms of Service](https://instrument.ninja/terms) - [FAQ](https://instrument.ninja/faq): common questions on instruments, plans, devices, and privacy. ## Optional - [Join a Class](https://instrument.ninja/join): students enter a 6-character class code from their teacher. - [Contact & Support](https://instrument.ninja/contact)
