Built for teachers and university lecturers
Teacher Assistant is a web-based tool that uses artificial intelligence to create classroom materials for teachers and university lecturers. A teacher chooses the grade level, subject and topic, and Teacher Assistant generates presentations, quizzes, practice exams, worksheets, interactive activities and video lesson scripts in minutes. Every account receives 20 free credits each month with no payment details required. The Plus plan includes 500 credits per month for $5, and the Pro plan includes 2,000 credits per month for $9. A quiz costs 1 credit, a presentation or practice exam costs 2 credits, and an interactive activity costs 5 credits. If a result is not good, its credits can be returned with one click. Teacher Assistant works in any web browser on a computer, tablet or phone, so teachers can prepare lessons at school or at home. Compared with building materials from scratch, it saves preparation time and lets teachers adapt every resource to their own class level.
