Built with teachers, powered by AWS: How Sanoma Learning created Sanna, its AI teacher assistant

This article describes how Sanoma Learning, Europe's largest K-12 educational publisher, partnered with AWS to build Sanna, an AI teacher assistant designed specifically for classrooms rather than generic AI tools.

• Sanna launched October 1, 2026 in seven European countries, supporting 25 million students across 11 countries
• Built on Amazon Bedrock with curriculum-grounded content and visible sources teachers can verify
• Developed collaboratively with 1,500 teachers across seven countries through testing and pilot phases
• Pilot results: 88% rated output quality equal or better than their own work; 75% used outputs directly in classrooms
• Enables lesson differentiation for diverse learners (dyslexia support, advanced students, language learners)
• Keeps teachers in control with AI suggesting, organizing, and helping while teachers make final decisions
• Grading and feedback module in development to scan tests and suggest scores for teacher calibration

Sanna demonstrates how educational AI should complement rather than replace teachers by grounding AI in trusted materials, maintaining teacher control, and prioritizing student outcomes.
