Lessonly vs Planbook

Lessonly is a web-based AI lesson-planning platform for teachers and educators in the United Kingdom. Its AI generates curriculum-aligned lesson plans with differentiated content for different key stages. A dashboard supports class groups, student profiles and schedule organization, while teaching guides, progress tracking and a lesson-plan library support ongoing teaching work. The intended users include teachers, tutors, early career teachers and trainees. Listed capabilities include standards alignment, collaboration and AI lesson generation; mobile access is web-only. The free-forever plan costs nothing and does not require a credit card. Lessonly says prompts and generated content are not used to train AI models, though AI providers may retain submitted data for up to 30 days for abuse monitoring and safety. Account data remains while an account is active and for 30 days after deletion; user content is deleted within 30 days of account deletion. The service is not guaranteed to be continuously available or uninterrupted.

Planbook is a web-based lesson planning and assessment service for teachers and schools, with Android and iOS apps. Teachers can organize classes, lessons, units, schedules, and school events, then use student accounts to track attendance, grades, performance, and standards achievement.

Sign-in options include Apple, ClassLink, Clever, Google, and Microsoft. Exports include PDF, Microsoft Word, Google Calendar, and Google Docs. Planbook lists a free plan and a 90-day trial. Individual teacher subscriptions are $16 a year for three years, $18 a year for two years, or $20 a year for one year.
