Masterplan · iPhone app
Point A, point B. Masterplan draws the middle.
Write where you are and where you want to be, or just an idea. Masterplan can ask up to three questions, then four intelligences each push the route their own way. You edit the routes and choose one. That’s where it ends: choosing a route is a decision, not an action.
- Routes you can edit
- AI runs on the phone
- Stays on your iPhone
In development.It runs on Joshua’s iPhone today. It isn’t on the App Store or in TestFlight yet.
What it does
Look at the route before you walk it.
Write a plan by hand, or ask the AI for routes. Every AI route is labelled, nothing is chosen for you, and your edits are kept with every version.
Both ends first
Say what’s true right now and how you’ll know you’ve got there. Not a goal yet? Write the idea down and sketch where it could go.
“What’s true right now? What do you have, and what’s in the way?”
Up to three questions
Before it plans, Masterplan can ask up to three questions, and only ones that could change the route. Each says why it’s asking.
“Answer any, skip any.”
Routes with their weak spots
Each route comes as steps, with the strongest case against it and the smallest test you could run first. Each step names the intelligence that pushed for it most.
Yours to change
Edit anything. AI routes say “Written by AI on this iPhone”, and once you change one, “Written by AI, edited by you.” Every version is kept. Set a plan aside, open it again, or share it as text.
Ends from the other apps
Start from a Scatterplot project as Point A, or pick an Endgame goal as Point B. Each comes across only when you tap.
Choosing isn’t doing
Masterplan doesn’t send, book, buy or start anything. Pick a route and it’s marked as your choice. The rest is up to you.
“Masterplan doesn’t do anything on your behalf.”
The four intelligences
Four ways of seeing the same road.
The names come from the world Agent Big Head comes from, where nearly everyone is a genius. In the app, each is a lens. It changes what a route leans on. Your facts, your limits and the ethics stay fixed, whichever lens is leading.
Brilliantist
Invent your way there: tools, experiments, something new.
Leads the Brilliant PlanDiabolicist
Dare: the bold, unexpected move most people won’t try.
Leads the Diabolical PlanConspiricist
Follow the threads: hidden links, patterns, what’s really going on.
Leads the Conspiratorial PlanMastermind
Play the long game: sequence, position, quiet preparation.
Leads the Grand Plan
- Masterplan · all four, evenly
- Brilliant Plan
- Diabolical Plan
- Conspiratorial Plan
- Grand Plan
- Custom Plan · your own blend

Agent Big Head: Four geniuses, one route, and none of them gets to push the button. That’s the part I like. Exploring an idea instead? It picks one lens at random. Spin again if you don’t like the view.
Where it fits
One family, one IDuh Pipeline.
Scatterplot and Informant work out where you stand. Endgame says where you’re going. Masterplan is the middle. It works on its own too: type both ends yourself.
Point AWhere you are
The middleThe route between
Point BWhere you’re going
Works today, on a tap
- Scatterplot → Masterplan. Send a project, with your own Point A note, as the start of a plan.
- Endgame → Masterplan. Pick a goal as the plan’s end.
- Scatterplot ↔ Endgame. Link a project to the goal it serves, and open one from the other.
- Scatterplot → Informant. Suggest topics to follow. Only the topic names you tick go across.
Not yet
- Informant evidence into a Masterplan plan.
- Keeping a plan up to date when its project or goal changes. For now, you send it again.
Hand-offs move between apps on the same iPhone. A link is a reference, not a copy, and nothing is sent until you tap.
Where your plans live
Plans stay on this iPhone.
What stays put
- Your plans, routes and every version of them are kept on your iPhone. There’s no Masterplan server.
- Routes and questions are written by Apple’s on-device model. Your plan isn’t sent to a cloud AI.
- Export all your plans as a file, or delete one plan or all of them, from Settings.
What touches the network
- Sign-in uses GeniusID, the IDuh Genius account. Signing in doesn’t upload your plans.
- Hand-offs from Scatterplot and Endgame travel between apps on the same iPhone, and only when you tap.
- Nothing else. Masterplan has no way to act in the world, so a chosen route can’t start anything.
Where it stands
Built and planning, not ready to hand out.
Everything in “What it does” is built and running on Joshua’s iPhone. The AI routes are still being tested on a real phone, and we haven’t measured whether four lenses beat one plain plan. There’s no download, beta or sign-up yet.
Built
- Plans by hand: both ends, routes, steps, the case against and the smallest test
- Questions, the Perspective picker, the four intelligences and Spin again
- Version history, set aside, share as text, export and delete
- Point A from Scatterplot and Point B from Endgame
Not yet
- A second opinion on a plan from Agent Big Head
- Sync across devices, and a web companion
- Informant evidence as part of Point A
- Live updates when a project or goal changes. For now, send it again.
Questions
Short answers.
Can I get it?
Not yet. Masterplan isn’t on the App Store or in TestFlight. When that changes, this page will say so.
Are the four intelligences separate AI agents?
No. They’re four ways of weighting one plan, written by one on-device model. The percentages are emphasis, not a measurement.
Can it carry out the plan for me?
No, on purpose. Choosing a route only marks it as your choice. Masterplan can’t send, book, buy or start anything.
Which iPhones will it work on?
Writing plans by hand works on its own. The AI routes and questions use Apple’s on-device model, so they need an iPhone with Apple Intelligence turned on.
The rest of the family
Three more in the family.
Point A · What you’ve gatheredScatterplot Catch notes, links, photos and places. File them into projects and find them by day or on a map.
Point A · What’s happening out thereInformant Follow the topics you pick, from sources you approve, in a brief that ends.
Point B · What done looks likeEndgame Decide what success means before you begin, and keep every version of the goal.
