Free AI Sub Plan Generator for Substitute Teachers

Free AI sub plan generator. Pick a unit and a day, and get a printable substitute plan with materials, timing blocks, a student handout, and sub-facing notes. Zero student data.

How It Works

  1. Pick your unit + day: Choose the unit from your workspace and the day you'll be out. Optionally pick which of that day's lessons the sub will cover.
  2. AI writes the plan: In about 25 seconds, the AI reads your lesson content and produces a complete substitute plan: overview, materials list, timing blocks, student handout, sub notes, and expected troubleshooting.
  3. Print and leave: Download and print. Leave the printout on your desk. The sub picks it up and runs your class.

Frequently Asked Questions

What is a sub plan?

A substitute-teacher plan is a printable one-class-period packet you leave for the sub covering your class. It includes the day's overview, a materials list, minute-by-minute timing blocks, a student-facing handout, sub-only notes, and 3-5 "if this, do that" troubleshooting moves.

Do I need student answers or names to generate one?

No. The generator reads only your unit's lesson metadata (titles, objectives, activities, materials) and produces a plan that refers to students as "Group A" / "students" / "the class." Never touches student names or per-student data.

Where does the lesson content come from?

From your unit's Stage 3 lesson data (the lesson-by-lesson plan you built in the Unit Planner). If Stage 3 is empty, the generator falls back to Stage 2 slot briefs. If neither exists, it writes a generic recovery plan on the unit topic.

What does the "sub experience level" toggle do?

It tells the AI how much classroom-routine scaffolding to include in the sub-notes column. "First time" adds extra location cues ("materials are in the top drawer") and routine spell-outs. "Experienced" keeps notes tight because the sub already knows how a classroom works.

Can I refine the plan after generation?

Yes. Type feedback ("add a bathroom-pass note", "the sub doesn't know middle schoolers", "cut the second discussion block") and the AI revises the plan while preserving the printable structure.
