The promise

Trade the Sunday-night spiral for a plan that's done before dinner.

This isn't a folder of prompts you'll forget by Tuesday. It's a four-week system that turns AI into the part of your week that quietly handles itself.

What's inside

Built around what you actually do on a Sunday.

Every page maps to a real teaching task.

01

A full week, planned in one sitting

Build one reusable planning prompt that returns differentiated lessons — ready to teach, not ready to rewrite.

02

Calmer classroom routines

Turn the messy moments — transitions, behavior, group work — into scripts and routines that fit your room.

03

Grading in a fraction of the time

A feedback workflow that sounds like you — specific and human — without the Sunday-night stack of papers.

04

The admin, handled

Newsletters, parent emails, data notes, PD reflections — drafted in minutes so they stop eating your evenings.

The method

Four weeks to a system that runs itself.

A prompt list leaves you on your own. This walks you from first try to lasting habit — one small step a week.

1
Week one

Set up your week

Build the one planning prompt you'll reuse every Sunday from now on.

2
Week two

Make it yours

Tune the system to your grade, subject, and the students actually in your room.

3
Week three

Reclaim grading

Put feedback on a workflow you can run on autopilot — and still sound like you.

4
Week four

Keep it forever

Lock the whole thing into a 90-minute ritual you look forward to, not dread.
