A product spec, screen plans, and build steps for your coding agent.

Generating… usually about a minute.
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.

**Ad free version of Offbook!** Hi — I'm Steve. I'm a working actor, and I built Off Book! for myself because I was tired of scribbling on scripts and recording lines into voice memos I could never find again. Turns out a bunch of other actors wanted it too. So here it is, made by an actor, for actors. THE GIST Record your script line by line, then play it back to run your scenes anywhere — on the bus, at the gym, pacing your kitchen at 1am the night before opening. It's dead simple: • Make a Work (your play), add your Scenes, drop in your Characters, and Record your Lines. • Recorded a 30-line scene and one line's out of order? Don't you dare start over. Tap the "+" to slip a new line in, or just press-and-hold a line and drag it where it belongs. Voilà. • Scenes out of order too? Same deal — long-press and drag. Fixed. NOW REHEARSE Tap the Rehearse icon and you're in. Play the whole scene, or pick the character YOU'RE playing and flip on "Mute My Line" — the scene plays right up to your cue, then pauses just long enough for you to nail the line before your next cue rolls in. Want a little nudge? "Cue My Line" gives you a friendly *ding* right before it's your turn. And here's the good part for runaround rehearsing: playback keeps going when your screen locks or you switch apps. Lock-screen, Control Center, and headphone controls all work — so you can run lines completely hands-free. Speed it up, slow it down, loop a scene till it sticks. LINESYNC — RUN LINES WITH YOUR CAST Doing a show with other people? LineSync lets a director share a show's lines and recordings with the whole cast across phones. Invite your actors by email; they sync everything to their own phone for FREE. As castmates record their lines, the director hears them show up automatically — no nagging. LineSync is a small monthly subscription per show, paid by the director. The cast never pays a dime. BUILT FOR EVERY ACTOR Dynamic Type, VoiceOver, and Dark Mode work throughout — because the stage is for everybody. Got a slick feature idea, or (gasp!) found a bug? Hit the support link and there's an email box waiting at the bottom — I read them myself. Now go get off book. Break a leg. — Steve ——— PRO TIPS ——— • "It won't save my lines!" → You probably skipped the microphone permission. Reinstall and tap YES when it asks, or go to iPhone Settings → Off Book! → switch Microphone ON. • To DELETE a Line, Character, Scene, or Work: swipe right-to-left and tap Delete. Careful — deleting a Character also deletes its Lines. • Long scene, phone left unattended? Set Auto-Lock to a long time (or Never) so it doesn't nap mid-rehearsal.

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.
