From brief to plan
Write what you are teaching in a few lines. Pick a format and a grade band, and get a complete plan with objectives, a timed sequence, assessment and differentiation to edit.
Lesson Plan Generator is an AI lesson plan generator. Write a brief of 5 to 400 words, choose one of five formats (standard, 5E, weekly, unit plan or worksheet) and one of four grade bands (elementary, middle school, high school or college), and Claude Sonnet 5 writes the plan following our lesson-planning rules. It uses the standards you give and is told never to invent standard codes. Each plan costs 10 purchased credits.
Subject, topic, grade, length, standards and class notes, in any order. Missing details become stated assumptions.
Each format has set sections, from objectives and success criteria to closure, so plans are complete and consistent.
Timed parts are planned to add up to your lesson length, and weekly and unit plans pace the work across lessons.
Standards you give are quoted as written, and the planner is told not to make up codes when you leave them out.
Support, extension and strategies for multilingual learners in every plan.
Briefs with no lesson topic, or that ask for harmful content, are declined and their credits refunded.
The topic, grade, minutes and anything about your class.
One of five formats and one of four grade bands.
The cost shows before you start; the plan appears in the result box.
Check facts and timings, adapt it for your students, then copy it into your planner.
A generator helps most where planning is slowest: a first draft for a new topic, a differentiated version of a lesson you already teach, a 5E sequence for a lab, or a week laid out from one goal. It gives you a structure to edit instead of a blank page.
It does not know your students, your school's curriculum map or what happened in yesterday's lesson. Put those details in the brief, and treat the result as a draft that you review and adapt.
Short briefs work, but specifics help the most:
You remain responsible for what you teach. Check facts, sources and age-appropriateness, and follow your school's policies on AI tools. Do not put students' names or personal information into a brief; describe needs in general terms instead.

Claude Sonnet 5, through a commercial model API, with our own lesson-planning instructions for structure, timing, accuracy and plain-text output.
It quotes any standards you paste into the brief and builds the objectives around them. It does not look up standard codes and is told not to invent them, so copy them from your curriculum.
Yes. Write the brief in the language you want, and the plan comes back in that language. A teacher fluent in it should review the result.
Please do not include names or personal details. Describe needs in general terms, such as three students reading below grade level, which is all the planner needs.
