Our mission
To give every IB student the thing the diploma never provides: a clear answer to “what should I do right now?”
The IB doesn't fail students because the content is impossible. It fails them because six subjects, an Extended Essay, TOK, CAS and a rolling wall of internal assessments arrive with no shared calendar and no order of operations. We think the planning should be the software's job, so the studying can be the student's.
Our vision
An academic operating system that follows a student from the IB to whatever they do next.
We started with the IB because it's the hardest, most deadline-dense diploma in the world — if planning works here, it works anywhere. The engine underneath doesn't care which curriculum it's pointed at, and neither do the deadlines that follow: A-levels, AP, university applications, and the degree after that.
Everything the diploma throws at you, in one place.
A plan, not a to-do list
Tell IBOS your subjects, deadlines and the hours you actually have. It ranks everything by importance, urgency and what you've been avoiding, then lays tonight out hour by hour.
Built around IB deadlines
IAs, the EE, TOK, mocks and tests are first-class. The closer a deadline gets, the harder it pulls on your plan — so nothing quietly slides until the week before.
Weak areas surface themselves
Flag a topic you're stuck on, or mark a session as a struggle. IBOS remembers, and brings that topic back before it becomes an exam-week problem.
Say it in plain English
“Push my Math IA to Friday.” “I only have two hours tonight.” Sage understands, makes the change, and replans around it.
Set up in about two minutes.
Answer a few questions
Your subjects and levels, which year you're in, when you sit exams, and when you're actually free.
Get tonight's plan
A ranked, time-blocked schedule that fits the hours you have — not a generic revision timetable.
Tell it what changed
Miss a session, add a test, get stuck on a topic. IBOS re-plans instead of guilting you.
Meet Sage, who does the admin.
Sage lives in the corner of every page. Tell it a test moved, a topic isn't landing, or that tonight fell apart — it edits your subjects, deadlines and plan for you, and never touches your essays. Feedback on your writing, yes. Writing it for you, never.
Your work stays yours
Your study data lives in your account and is never sold or used to train anything. AI features are optional and can be switched off entirely in Settings — with the switch enforced on the server, not just hidden in the interface. You can export everything you've put in as a single file, whenever you want.
What are you doing tonight?
