Common Planner vs TeacherHero

Common Planner is a web-based collaborative lesson planner for teachers, schools, and districts. Teachers can create lesson and unit plans, organize classes, and reuse planbooks and lessons across school years. They can search for standards, attach them to units, and track which standards have been taught. Shared planbooks support co-planning, sharing plans with administrators, and borrowing plans from other teachers. School leaders can review planning status, standards coverage, and pacing, then comment on lesson plans. The school product page describes AI-assisted insights for identifying missing standards, pacing issues, or instructional gaps. Basic for Teachers includes an AI-powered lesson assistant, daily, weekly, and monthly planning, up to 50 Google Classroom posts, and file uploads from a computer or supported storage services. Pro includes unlimited Classroom posts, unit planning, automatic standards tracking, and up to five collaborators. The Basic plan is free forever; Pro is listed at $5.59 a month, with a one-payment amount of 71.88 USD. The Schools plan includes school-wide templates, membership management, staff training, and ongoing support. There is no app, but the service works through a browser on tablets and smartphones.

TeacherHero is a web-based AI lesson-planning and instructional-coaching platform for K–12 teachers. It organizes courses into units, weeks, and lessons, then uses that connected curriculum context to generate lesson plans. Generated lessons follow six gradual-release sections: Warm-Up, I Do, We Do, Y’all Do, You Do, and Exit Ticket. Teachers can choose among 24 teaching strategies. Pro adds unit assessments, learning-target alignment checks, lesson audits, differentiation, rewrites, and source enhancements. Lessons can be exported as PDFs, slides, and Google Drive files; listed formats also include PowerPoint and Word. Google sign-in is available, and optional Drive access is limited to files the app creates. TeacherHero says it uses OpenAI’s API for every AI call, does not use curriculum or uploaded materials to train models, and sends uploaded excerpts to AI only after teacher confirmation. The maker says it does not collect student names, records, or work, and the product has no student accounts. A free account is available; Pro costs $8.99 per month after a 7-day free trial and renews monthly until canceled.
