Inside Syllabo

Six parts

Every question, flashcard and lesson is tagged to an official syllabus point, across 29 subjects and more than 53,000 questions. That is how the app knows what to show you next.

06Buddy

A study buddy that keeps your streak.

Your buddy reacts to every answer, cheers a streak and sulks when you skip a day. Dress it in any of 107 skins, each standing in its own illustrated scene, and teach it a topic to prove you understand it.

04 / How it works

Three steps

How it works

Set up once. From then on the app decides what to show you, and you decide how long.

  1. 01

    Choose your subjects and levels.

    Pick your six from 29 IB Diploma subjects. Add your school's units and your upcoming tests with the topics they cover.

  2. 02

    Open the app whenever you have a gap.

    In a taxi, before dinner, between lessons. Slide to the time you have and start, or search a concept and drill just that.

  3. 03

    Let mastery and mistakes steer.

    Every answer updates a spaced-repetition score per syllabus point. Mistakes stay open until you resolve them, and exams pull their topics forward.

05 / Compete

Leagues • Duels • Rings • Skins

Compete. Leagues, duels and daily rings.

Every question you answer earns XP and coins. They feed a weekly league, duels with friends, daily rings and a buddy you dress up. Nothing here can be bought with real money: the only way to win is to study.

Leagues

A new race every week.

You are placed in a bracket of up to 30 students at your level. XP from every session counts, the top quarter climb a badge and the bottom few slip back. Sixteen badges run from Bronze up to Luminary. Or make your own league for your class or friends, share a six-letter code, and play for a weekly coin prize or a buy-in pot.

    Duels

    Same ten questions. Best score wins.

    Challenge a friend on any topic, pick multiple choice, short or long answers, put coins in the pot and switch hints off if you want a straight test. You both have 48 hours, and the winner takes the pot.

    Daily rings

    Five minutes a subject.

    A ring for each subject you are focusing on, closed by minutes studied or points practised. Close them all for coins and a crate, keep it up for a perfect week, and hold the flame to start today's session and keep your streak alive.

    Close every ring today+100 coins + a crate

    Crates and skins

    107 skins to collect.

    Coins open crates, crates drop skins for your buddy, from common to legendary, each with its own scene and eight poses. Rare colourways are numbered, so your Gold #7 of 10 is the only one. A daily drop, daily login rewards and medals for the milestones.

      08 / Questions

      Six answers

      Questions

      Are these real IB past papers?

      The app ships original questions written in IB paper format with mark schemes. Real papers are IBO copyright, so they are not bundled. If your school gives you access to past papers, you can type or paste their questions in under Learn › subject › Saved questions. Tag each one with its syllabus points and marks, and it appears in your sessions, where the tutor can mark it against your mark scheme.

      Is the AI tutor really free?

      Yes. The AI tutor and AI marking are included at no cost, with a daily allowance to keep things fair for everyone. They need a free online account (a new install gets its first day as a guest), and you can turn AI off at any time in Settings.

      Does it work without an internet connection?

      Mostly. Practice, flashcards, lessons, your progress and on-device marking all work offline. The AI tutor and AI marking need a connection, and marking falls back to the on-device version when you are offline.

      Where is my data stored?

      Your study data lives on your device. If you create an online account, a backup is kept with our database provider, Supabase, so you can sign in on another device and add friends. Messages to the AI tutor and answers sent for AI marking go to Anthropic's Claude through our server, which does not keep them. The privacy policy has the details.

      Which subjects are covered?

      29 IB Diploma subjects across Groups 1 to 5, each with its official syllabus outline and practice questions: more than 53,000 in all. Both maths courses, the sciences, Economics, Global Politics, Business Management, Psychology and SEHS have the deepest banks, with dozens of questions on every syllabus point, and the rest grow with each update. The arts are not included, because they are assessed through practical work and portfolios rather than exam questions.

      Is it affiliated with the IB?

      No. "International Baccalaureate" and "IB" are trademarks of the International Baccalaureate Organization, which does not endorse this app.
