Paying for it? Here’s what you should know.
- What it does
- Plans their study across their subjects, around their week.
- The grade
- A predicted grade for each subject, always with its range. Separate from school’s, and never a promise.
- Parent view
- Coming: a weekly summary your child chooses to share, with each grade’s range and their study time. Never their answers.
- AI
- Writes hints and explanations, never the plan or the grade, and never sees their name or email.
- Data
- Stored in the EU. Never sold. No ads.
What the research says. What Elio does.
The findingWhat Elio does
Spreading study out beats cramming it.
Cepeda, Pashler, Vul, Wixted and Rohrer (2006), Psychological BulletinBrings each topic back before it fades.
Testing yourself beats re-reading.
Roediger and Karpicke (2006), Psychological ScienceAsks instead of showing.
Highlighting and re-reading rate low.
Dunlosky, Rawson, Marsh, Nathan and Willingham (2013), Psychological Science in the Public InterestPractice first, notes second.
Learning is fastest when most answers, not all, are right.
Wilson, Shenhav, Straccia and Cohen (2019), Nature Communications, a computational resultAims each question where you get most of them right.
Pricing

How does Elio predict my grade?
Every answer updates Elio’s predicted grade for each subject, weighed by how hard the question was. It is shown on the 1 to 7 scale as a range, which narrows as you answer more; while there is too little to go on, Elio says so. It is Elio’s own prediction, separate from the predicted grades your teachers give, and never a promise.
Is Elio part of the IB?
No. Elio has been developed independently from and is not endorsed by the International Baccalaureate Organization.
