What Is Root? The Free AI Tutor for GCSE, IB & A Level

It's 11pm, there's a mock on Thursday, and nobody has told you which of your nine subjects to start with.

Root is an AI tutor for GCSE, IGCSE, IB and A Level students that learns how your brain learns. It teaches you one to one, spots what you don't understand, marks your work the way an examiner would, and manages your studying for you: building the plan, scheduling the reviews, and telling you what to do next.

It's free to start, there's no card to enter, and the free plan doesn't expire. If you'd rather try it than read about it, start here; if you'd rather watch it teach first, see a real session.

If you've arrived from one of our revision guides, you already know the awkward truth every guide ends on: the techniques that work take real effort to organise. And if this sounds like ChatGPT in a school uniform, keep reading. The difference is the whole point.

Root at a glance

Why studying on your own feels so hard

When you revise alone, you're secretly doing four jobs at once:

• The teacher, working out how to explain each topic to yourself
• The examiner, judging whether your answers would actually score marks
• The planner, deciding at 10pm whether tonight is biology or the maths you've been avoiding
• The memory manager, tracking which topics are fading and need another look

The research covered across this blog, from active recall to spaced repetition, is clear about what works, and revising well is a learnable skill. But the same research is honest about the cost: the effective techniques take sustained effort and constant scheduling across every subject at once. Knowing that retrieval beats re-reading doesn't tell you which of forty topics to retrieve on a Tuesday in March.

That gap, between knowing what works and having the time and organisation to run it, is the gap Root exists to close.

The problems Root was built to fix

• "I revise but it doesn't stick." Re-reading feels productive and quietly fails, as the study techniques evidence shows. Root makes every session retrieval based, so the effort goes where memory is actually built.
• "I forget everything after two weeks." The forgetting curve is undefeated unless reviews are spaced, and spacing is a scheduling problem. Root does the scheduling.
• "I never know where to start." Deciding what to study is its own exhausting job, and vague plans feed procrastination. Root always has one specific next step waiting, so there's nothing vague to put off.
• "I'm stuck on tonight's homework." Photograph your working and drop it in. Root finds the exact step where it went wrong, then teaches you that step instead of doing the question for you.
• "I know the content but lose marks in exams." Knowing a topic and answering the way mark schemes reward are different skills. Root's examiner style marking trains the second one.
• "I panic in exams." Confidence is rehearsal, and exam stress shrinks when the paper holds no surprises. Root drills you in your exam's real format, marked the way it will really be marked, until it looks familiar.
• "I'm just bad at this subject." Usually false. Usually the explanations never matched how you think. An explanation tuned to your brain, tried a different way until one clicks, changes the story.

What Root actually is

Root is two things working together.

An adaptive tutor that teaches the way your brain thinks. Not a chatbot that answers questions, and not an app that just marks answers right or wrong. Root teaches: it breaks topics down, asks you questions instead of lecturing, and builds your understanding step by step, using the two most replicated findings in learning science, retrieval and spacing, on everything you study.

An AI manager of your academic life. You never need to work out what to study. Root builds your study plan, decides what today's session should cover, brings weak topics back at the right intervals, tests whether the knowledge actually stuck, and tells you the next thing to do.

It's built in the UK around the GCSE, IGCSE, IB and A Level curricula, and everything below is how those two jobs get done.

How Root teaches: like a tutor, not a search engine

Ask Root about a topic and it won't dump an essay on you. It works the way a good private tutor works. A typical exchange looks like this:

You: I don't get how to solve x² + 5x + 6 = 0

Root: We'll get there, and you'll do most of it. Quick check first: if two things multiply together to make zero, what do you know about at least one of them?

You: it has to be zero?

Root: Exactly, that's the entire trick. So if we could rewrite x² + 5x + 6 as two brackets multiplied together, what would we know about each bracket?

• It builds understanding before answers. Root asks you to try, watches where your reasoning goes, and guides you to the answer rather than stating it. Getting there yourself is what makes it stick.
• It learns how you learn, and uses it. Say the textbook definition of photosynthesis has bounced off you twice. Root notices, parks the definition and tries it as a factory instead: light as the power supply, chlorophyll as the machinery. If the analogy is what clicks, Root remembers, and your next topic starts from how you think, not how the textbook does. Two students asking the same question get different lessons.
• It draws. Graphs, triangles, force diagrams, molecule structures, flowcharts: Root produces real diagrams inside the lesson, because some things should be seen rather than described.
• It marks like an examiner marks. Answer a practice question, or photograph your handwritten working, and Root marks it in the style your mark schemes reward, part by part, essays included. The feedback sounds like this: "In part (c) you found the gradient and then never used it, which is where both accuracy marks went. 7 out of 9. Want to try the missing line before I show you?"

The lesson happens in a real workspace, too: proper maths notation, a scratchpad, a built in scientific calculator, and a focus mode for when you need the world to go away. And this is why using Root isn't cheating: it won't write your homework for you. It makes you do the reasoning, the way a tutor would, because you'll be alone with the paper on exam day.

Don't take this page's word for any of it: watch a real session, or start your own. Free, no card, about two minutes.

Root vs ChatGPT: what's the difference?

The honest answer first: ChatGPT is free, genuinely useful, and plenty of students use both. But handing you an answer feels helpful and teaches you very little, and sixty messages of being taught beat unlimited answers you'll forget by Friday. Root is deliberately built to do what a chatbot doesn't:

• It teaches before it tells, guiding you to answers so the understanding is yours.
• It keeps a map of you. Root tracks which topics you've mastered, which keep slipping, and which explanations work on your brain, all organised around the exam you're sitting. No chat window does that job.
• It knows your exam, so practice and marking match what your curriculum actually rewards.
• It runs the whole system around the conversation: the plan, the spacing, the testing, the tracking. A chatbot is a tool you have to wield well. Root wields the tools for you.

Five ways to use Root

• Tutor mode is the classic lesson above: one to one teaching on whatever you're studying.
• Test Prep mode generates questions in your exam's format, including interactive ones where you plot the graph or fill in the table yourself, the way the real paper asks. Feed it a past paper, PDF or photo, and it works from the real thing, marking question by question with what scored, what didn't, and why.
• Revision mode diagnoses your weak topics across everything you've covered, builds you a tickable plan, and re-tests those topics until they hold.
• Get Ahead mode teaches you the next thing in your curriculum before your class gets there. A few sessions over the summer means starting September already ahead.
• School Project mode coaches you through projects and coursework against the actual rubric you're graded on, the way a teacher is allowed to: guidance on your own work, never writing it for you.

It runs the system so you don't have to

• A study plan built for you, from must-know basics through exam application up to challenge material, updating as you progress. No more staring at a blank revision timetable or agonising over the plan itself.
• Spaced repetition without the admin. Root tracks every topic you've covered, notices what you keep getting wrong, and resurfaces the right material at the right time, mixing topics as it goes so you're always working on what needs work. If you want, it will also remind you when reviews are due. The schedule most students can't sustain by hand simply happens.
• Notes and flashcards from your own work. A notes hub for every unit: save explanations mid lesson or write your own, then turn any of it into flashcard decks you can drill.
• Built for week four, not just day one. Most study apps die in your downloads folder because every session starts with you deciding what to do. "I always give up after a week" is a design problem, so Root removes the decision (one next step, always waiting) and makes showing up worth protecting: weekly streaks with a streak shop, quests, XP, levels and badges, a mastery garden that grows as you learn, and friends you can add with a code so you're not doing it alone.

Is Root free? What the free plan includes

Root's free plan is a working study system, not a locked demo. Without paying anything, and without entering card details, you get every week:

• Real one to one tutoring: 60 messages from you, across up to 3 sessions a week, in 2 active units (a unit is one topic block, like Quadratics or Forces; finish one and start another whenever you like, so one maths and one science on the go works fine)
• Exam style practice: 2 practice tests a week, generated for your curriculum and marked question by question
• Revision mode: 25 messages a week of sessions that diagnose weak topics and bring them back until they hold
• Your own materials: attach two documents per unit, like specs, class notes or past papers
• Notes and flashcards: save what you learn, drill it later
• A learning profile that never stops updating: Root keeps learning which explanations work on you the entire time

One thing worth saying plainly: the free plan runs on Root's fast tutor model, and Pro upgrades you to its most capable one. The teaching method is identical; the ceiling is higher.

New accounts also unlock a five day trial of the Pro plan as they get started, with no card required. When the trial ends you drop back to the free plan automatically and nothing is charged. Pro is $18.99 (about £15) a month when you want it: limits high enough to stop mattering, the most capable tutor model, unlimited units, and the full progress dashboard with your hours, questions answered and mastery tracked skill by skill. But free is not a countdown: it stays free, every week, for as long as you want it.

Create your free account and Root starts learning how you learn from the first question.

Who Root is for: GCSE, IGCSE, IB and A Level

Root is built for secondary school students aged 13 and up: GCSE, IGCSE, IB and A Level. It covers the core academic subjects with teaching styles tuned to each, because how you learn quadratics and how you analyse an unseen poem are not the same skill. Tell Root your course and exam board, AQA, Edexcel, OCR, Cambridge, WJEC or your IB programme, and it teaches to that actual syllabus.

It fits whether you're rescuing a grade, sitting comfortably and pushing for the top, or already ahead and wanting to stay there. Root meets you at your level, because its whole job is knowing your level.

Is Root safe? A word for parents

The comparison you're probably making is with a human tutor, so here is the honest version. A good private tutor at £35 an hour, once a week, is over £140 a month, for one hour of help. A great one is worth it: they know your child's school, they can read a mood across a kitchen table, and no AI replaces that. Root's job is the other six days, at £0 on the free plan, any hour your child needs it.

The three questions parents actually ask. First, Root will not do your child's homework for them: it teaches with questions and makes them do the reasoning, because they'll be alone with the paper on exam day. Second, data: conversations are processed by Root's AI provider, Google's Gemini, to generate replies; they're not used to train AI models, by Root or by Google, and Root never sells data. The full detail is in the privacy policy, and Root is for ages 13 and up. Third, screen time: the streaks reward showing up, not staying on. The weekly streak asks for 45 focused minutes across a week, not hours of scrolling. And because Root decides what to study next, "have you actually revised?" stops being your conversation to have.

If you're weighing up the options, our comparison of AI and human tutoring is written to be straight with you about both.

What Root is not

Root is not a human, and doesn't pretend to be: it can't know your school's inside jokes or sit beside you in the exam hall. Like any tutor, human or AI, it can occasionally get something wrong. It's built so mistakes get caught rather than believed: it works step by step, so a wrong turn is visible in the working rather than hidden in a final answer, its teaching is anchored to your actual curriculum, and practice is marked in the style real mark schemes reward. And it will never simply do the work for you, because handing you answers would be the one way to guarantee the grade doesn't change. For a balanced look at what AI tutors do well and where they fall short, our guide to AI tutoring doesn't pull punches.

Everything else on this blog still applies. You can run every technique here by hand, and every guide shows you how. Root simply removes the reason most students who know the techniques never benefit from them: the daily effort of being your own teacher, examiner, planner and memory manager, all before the actual studying starts.

Studying was never meant to be a solo job. Two minutes, no card: start free and let Root take its half of the job. Still unsure? Watch a real session first.
