Erudior is a free learning app for families and classrooms: full courses with lessons, quizzes, flashcards and drills, plus the attendance, grades and transcripts homeschoolers need. Your children's records never leave your computer.
Explore without saving learning data. No account required; optional local progress and export are available in the browser.
Early version: Erudior is still being built and tested. Don't use it to replace homeschool or regular school yet; it's fine as extra practice. See what's left before version 1.0.

For parents
Homeschool records that keep themselves
Set up your family once: your state, the school year and each child's grade. Erudior counts study time as your children work, proposes school days for you to confirm, and turns it all into the records your state asks for.
- Attendance and hours against your state's minimum, with reminders for notices and testing
- Grades and GPA from quizzes and tests, plus work you grade yourself
- Report cards, high school transcripts, progress reports and portfolios to print or save as PDF
- A password (or PIN) keeps the parent area to yourself
For kids
Each child picks their name and gets to work
Children see the courses you assigned them, in order, and pick up exactly where they left off. Lessons explain with worked examples and diagrams; quizzes check understanding before moving on.
- Assigned courses by subject; the next one unlocks when the current one is done
- Lesson quizzes, practice exams, flashcards that space out reviews, and math drills with fresh numbers
- A calculator beside every quiz and lesson: graphing for math and science
- Honors lessons for students who want to go further
Live rooms
Game-show quizzes for the whole family or class
Host a live quiz from the parent or teacher area. Everyone joins on a phone, tablet or laptop at app.erudior.com with a six-character code, no account needed. Run it at your own pace or against the clock, with points for speed.
- Questions from any course, lesson quiz or module test
- Answer counts after each question; scores only on the host's screen
- Players only ever see their own results
For teachers
Classroom mode
Teachers set up classes, assign courses with due dates and follow progress in a gradebook. Students work on the teacher's computer or their own: they open the class file, study, and hand in their work as a file the teacher imports.
- Class rosters, assignments and due dates
- A gradebook you can export as a spreadsheet
- Hand-in files are checked, so mix-ups and casual edits are caught
Courses
Real courses, not just question banks
Pick any course from the catalog and the app downloads it; after that it works offline. Math, science, German and professional exam prep today, with more on the way, plus courses written by the community for free learning.
- Every lesson ends with its key points and the common mistakes
- Formulas in their own panels, with diagrams and pictures
- New versions of a course are offered automatically, and your progress is kept
The courses
Every course is free, with lessons, practice questions, notecards and practice problems. Open any of them in your browser.
