LessonLock
An AI lesson-plan builder for K-12 teachers that drafts a full week of plans and walks the teacher through reviewing, refining, and approving each section with a logged decision trail.
K-12 teachers building weekly lesson plans aligned to standards
- Standards-aligned plan draft that asks clarifying questions before writing (class size, IEPs, prior knowledge)
- Section-by-section review with the teacher able to reject, edit, or annotate before the plan locks
- Decision log exportable to share with coaches, admins, or substitute teachers
- Differentiation suggestions that the teacher approves line-by-line, not all at once
Teachers are flooded with AI lesson tools that dump full plans without review steps; a tool that bakes in the human-in-the-loop moment per section matches how teachers actually want to work.
