Stories from the classrooms
“It's very rewarding to spend less time writing formative feedback — because now I can be more present in what the students are actually doing and give the individual support I want to give.”
Therese Cavalli-Björkman Christinaskolan, Lidingö“I'd say I save maybe half the time. But then the students probably get ten comments instead of five.”
Dominic Strandqvist Internationella Engelska Skolan, Kungsbacka“The AI is impressively detailed and close to how I would grade myself. It frees up time for me to focus on deeper pedagogical work.”
Alexander Carlé KMS Kullaviks Montessoriskola

Questions and answers
Frequently asked questions
What is Gradr?
Gradr is a Swedish platform for AI-assisted formative feedback and secure digital exams, built for schools. The AI in Gradr drafts feedback suggestions from the teacher's own instructions and criteria, and the teacher reviews and approves every suggestion before it reaches a student. Gradr is built by Gradr AB in Stockholm (reg. no. 559475-9630) and is used by teachers at over 100 schools across Sweden.
Does the AI grade students?
No. The AI in Gradr never sets grades, points, or summative assessments — multiple-choice questions are scored deterministically against the teacher's own answer key. In Gradr the teacher reviews and approves every feedback suggestion, and nothing reaches a student without the teacher's action. No automated decision-making within the meaning of GDPR Article 22 therefore takes place in Gradr.
Where is student data stored?
Student data in Gradr is stored on Gradr's self-hosted servers at Hetzner in Finland (EU), encrypted with AES-256 at rest and TLS in transit, with backups inside the EU. All AI processing in Gradr happens within the EU — Microsoft Azure OpenAI (EU data zone) and Google Vertex AI (Belgium) — and no personal data is transferred outside the EU/EEA. Gradr signs a GDPR Article 28(3) data processing agreement with every school customer.
