What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

A calmer home base for your teaching day. Plan with brAIn, check in with yourself, and find teachers who get it, all in one warm, thoughtfully designed space. Created with a teacher’s real day in mind, from the first bell to the final deep breath. The Teacher Brain brings planning support, wellbeing tools, classroom ideas, and a teacher community together so you have more room to teach. ONE APP. MORE ROOM TO TEACH. • brAIn: Tell it the grade, time, and topic. Get a lesson, exercise, or project starting point you can review and make your own. Speak or type, then save, star, and share. • Teacher Lounge: Share classroom wins, ask for help, and swap ideas with people who understand the work. Filter by Wins, Motivation, and Ideas. • Daily dashboard: Begin with a mood check, open your journal, keep a gentle streak going, and discover classroom-ready resources. • Calendar & planning: School and personal tasks in one view, with Google Calendar sync, custom event types, and a daily planner. • Wellbeing tools: Journal with photos and voice notes, capture sunshine moments, run visual classroom timers, build habits, and start the morning with a pep talk. • Shop: Browse teacher-created classroom books and resources when you want them. SMALL TOOLS FOR THE PERSON BEHIND THE LESSON PLAN. Mood check-ins, journaling, daily tips, a focus timer, and encouraging streaks help you make space for yourself inside a full day, without turning self-care into another assignment. Add home-screen widgets and optional daily reminders so a little support is there before the bell. BUILT FROM INSIDE THE CLASSROOM. The Teacher Brain was created with Kaitlyn Biernacki, a second-grade teacher and the creator of My Classroom Diaries. Teacher-created. Community-minded. Joyfully practical. ABOUT YOUR ACCOUNT, AI, AND PURCHASES Create a free account to save your journal, plans, Lounge profile, and brAIn creations. brAIn and Month in Review use AI to draft starting points and summarize your mood and planning stats. Every result is a starting point. Review it for accuracy, appropriateness, and your school’s policies before you use it with students. The app is free to download. Optional classroom resources are available as in-app purchases. Privacy: https://www.theteacherbrain.com/privacy Support: https://www.theteacherbrain.com/contact

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
