02LivingAdapts to every classroom

Your book, the starting point of every classroom

Schools adapt their materials or drop the textbook altogether. With Tangerine, your content is the living foundation each school builds its teaching on, not the rigid PDF they end up abandoning.

  • Teachers reorder, hide and add modules, for the whole class or just for the students who need it.
  • Your content lives alongside each school’s own materials.
  • When you update a program, the change reaches every classroom instantly.
For teachers
The platform fits the way they teach, not the other way around.
For students
Materials designed for their class and their pace.

02LivingLearning by doing

Your content stops being read and starts being practiced

People learn by practicing, making mistakes and getting help in the moment. Tangerine turns your content into practice with instant grading and support: the teaching argument that sets your digital project apart from a PDF with videos.

  • From a PDF, a topic or your digital program to activities ready for review, in minutes.
  • Automatic grading with feedback on every answer, plus teacher feedback on assignments and quizzes.
  • And when a student gets stuck, the AI Tutor guides them with questions instead of giving away the answer.

Retrieval practice, formative feedback and mastery learning: established learning science, not a trend.

For teachers
Every student practices with instant help, without thirty notebooks to grade. The tutor doesn’t replace the teacher: it gives them time back.
For students
Practice without fear: help arrives when they get stuck, not in the final grade.

02LivingAI Tutor

A tutor for every student. An assistant for every teacher.

The AI Tutor supports students as they practice, study and review, always from your content and with your book’s method. For teachers, it prepares materials in seconds and shows who needs help and with what.

For students

It guides, it doesn’t give the answer

  • Progressive hints: the student always takes the last step.
  • One mode to practice, one to study and one to review.
  • Explains from your content, with voice, visuals and photos of the notebook.

For teachers

It gives back time and visibility

  • Lesson plans, questions, rubrics and feedback in seconds.
  • Materials adapted for autism, ADHD or dyslexia right from generation.
  • A radar showing who needs help and which concepts raise the most questions.

03BusinessYour brand, your community

Your brand in every session. Ours in none.

Your relationship with schools is yours, and it stays that way. The platform reinforces your brand in every session instead of putting a third party between you and your schools. We are the invisible technology partner.

  • Your logo, your colors and your own landing page, across the platform and every communication.
  • Your own iOS and Android app, and a tutor that carries your brand’s name.
  • Dedicated infrastructure for each publisher.
For teachers
One identity: the publisher they already know and trust.
For students and families
Seamless continuity between print and digital: same world, same brand.

03BusinessAdoption from day one

An empty platform is a dead project

A student who logs in and finds nothing doesn’t come back, and a license nobody activates doesn’t get renewed. That’s why we commit to making the start simple: your digital business only works if it gets used.

  • We migrate your content and your schools’ users from their roster: classes, teachers and students.
  • Training for your teams and for schools, live and on demand.
  • Activation by code or self-service, compatible with SCORM, xAPI and LTI.
For teachers
Less setup work: classes and content ready to go.
For students
They redeem their code and they’re in their class, with their content.
