K-12 and Schools
AI tools built for K-12 classrooms.
Automated essay feedback, personalized assessments, and trusted content tools — built so teachers can teach, and students get faster, fairer feedback at any scale.
Why K-12 needs the right AI
Generic AI gives wrong answers
Students turn to chatbots that confidently fabricate facts. Without a verified-content AI tool, schools either ban it or watch students learn from hallucinations.
Essay grading eats teacher time
Teachers spend hours providing written feedback on essays. The result is delayed turnaround, inconsistent rubric application, and limited revision opportunities for students.
Personalization at scale is impossible manually
Differentiating practice questions, feedback, and learning paths for every student is a math problem that defeats human bandwidth.

Frequently asked questions
Is Edtek safe for student data?
Yes. Edtek supports on-premise and private cloud deployment so student work and grades stay inside your district's infrastructure. For cloud deployments, data is encrypted in transit and at rest with strict tenant isolation.
How does Edtek prevent AI hallucinations in graded feedback?
EssayTutor evaluates student responses against teacher-defined model answers and rubrics — the AI doesn't fabricate scoring criteria. Feedback is anchored to the rubric and the source material, with traceable reasoning.
Can teachers customize the grading criteria?
Yes. Teachers define rubrics in plain English — including subject-specific frameworks. The system applies them consistently across every submission.
How long does deployment take for a district?
Most schools go live in days, not months. Upload assignments and rubrics, and the system is ready. No coding or IT lift required.
Does Edtek replace teachers?
No. Edtek automates the repetitive parts of feedback and assessment so teachers can spend more time on personalized instruction, mentorship, and high-value classroom interactions.
