An AI writing assistant schools can trust
Aule Writer · My own product · Romania · 2025
Schools want AI writing help for their students, but sending student work to an outside AI service is a privacy risk many cannot accept. Aule Writer brings AI writing assistance into the classroom with no student data ever leaving the school’s own machines.
In numbers
- Time: feedback on a draft in about 4 seconds, and each teacher saved about 3 hours a week on first drafts.
- Money: one server for €1,400, about €26 per student in the pilot, and nothing per request.
- Errors: teachers judged 91% of the feedback correct and useful, and 0 student texts left the school network.
- Adoption: 81% of students used it every week, and revised each draft 2.3 times on average instead of 1.1. Teachers asked to keep it.
- Scale: 2 classes, 54 students, 3 teachers, 6 weeks and 1,900 drafts, on a 7-billion-parameter model.
What it does
- AI writing assistance for students, built for use in class.
- Runs on the school’s own machines, so student work and data stay inside the school.
- Feedback, not answers: it points to the long sentence, the repeated word, the vague claim, and the student fixes it.
- A view for the teacher: what the class struggles with most, without reading every draft twice.
How it’s built
A small language model runs on one server inside the school network, and the classroom computers talk only to that server. The model is chosen and tuned for one job, feedback on student writing, which is why it fits on hardware a school can afford.
The school network is the boundary. Student work never crosses it.
Where it is
Piloted in a school in Romania: 2 classes, 54 students, 6 weeks. Teachers saw students revise their drafts more often, and asked to keep it after the pilot ended.
Why it matters
Whether people adopt AI depends on trust as much as on what the AI can do. Aule Writer starts from a school’s biggest concern, its students’ privacy, and builds the AI around it.
