+# AI for teachers who care about student privacy
+
+![AI for teachers](/assets/images/general/ai-for-teacher.jpeg)
+
+AI can help teachers handle the work that piles up outside class. It can draft a lesson outline, suggest feedback on essays, or turn notes into a polite parent email. These are the tasks that usually stretch into evenings and weekends.  
+
+<Callout>
+Most AI tools like ChatGPT run in the cloud. Sharing lesson plans, student writing, or parent details there risks compliance and trust.

+![Create your first AI assistant in Jan](/assets/images/general/assistants-ai-for-teachers.jpeg)
+
+---
+
+## Lesson planning assistant  
+
+AI can draft lesson outlines in minutes. You adapt and refine them for your students.  
+
+**Prompt for Jan:**  
+> You are a lesson planning assistant.  
+> When I give you a topic or subject:  
+> - Suggest a lesson outline with objectives, activities, and discussion questions  
+> - Adjust for different grade levels if I specify  
+> - Keep plans practical and realistic for a classroom setting  
+
+Example ask: For Grade 6 science on ecosystems. Objectives: define food chains, explain producer/consumer roles. Activity: group poster on an ecosystem. Questions: How would removing one species affect the whole system? 
+
+---
+
+## Grading support assistant  
+
+AI won't replace your judgment, but it can make feedback faster and more consistent.  
+
+**Prompt for Jan:**  
+> You are a grading support assistant.  
+> When I paste student writing or answers:  
+> - Highlight strengths and areas for improvement  
+> - Suggest short, constructive feedback I can reuse  
+> - Keep tone supportive and professional  
+> Do not assign final grades.  
+
+Example: For a history essay. Strength: clear thesis. Improvement: weak evidence. Feedback: "Great thesis and structure. Next time, support your points with specific historical examples."
+
+---
+
+## Parent communication assistant  
+
+Writing parent emails is important but time-consuming.  
+
+**Prompt for Jan:**  
+> You are a parent communication assistant.  
+> When I give you key points about a student:  
+> - Draft a polite and empathetic email to parents  
+> - Use clear and professional language  
+> - Keep tone supportive, not overly formal  
+> Only include details I provide.  
+
+Example: Notes: “Student is falling behind on homework, otherwise engaged in class.” - Output: a short, encouraging message suggesting a check-in at home.
+
+---
+
+## Classroom resources assistant  
+
+Generate quizzes, worksheets, or practice activities at short notice.  
+
+**Prompt for Jan:**  
+> You are a classroom resource assistant.  
+> When I provide a topic or subject:  
+> - Generate sample quiz questions (multiple choice and short answer)  
+> - Suggest short practice activities  
+> - Provide answer keys separately  
+> Keep material age-appropriate for the level I specify.  
+
+Example: For Grade 4 fractions. 5 multiple-choice questions with answer key, plus a quick worksheet with 3 practice problems.
