Use Muse

“yes, YOU can save money and find happiness with Amazing AI”

Working cover title: Muse It! — 11 Ways That Muse Will Change Your Life

A general reader's guide to living with a personal AI agent — not a book of prompts. This is one sustained, documented experiment: a busy person handed a capable AI agent real jobs — money, travel, family, health, friendship — and it did them, remembered, and followed up. The receipts are the argument.

The proof, to the dollar

Every figure in the book comes from a dated ledger the author actually kept. One person's documented experience — honestly labelled, your mileage will vary. What transfers is the method.

the ledger's first six weeks — and it keeps growing

Flights rebooked on points the night fares dropped. A wife's forgotten unclaimed property recovered from the State of California. Subscriptions audited and cancelled. An insurance claim summarised and a dog's policy corrected. The agent did the work; the author kept the receipts.

The first book to be read with your Muse

Use Muse is designed to be read with the reader's own Muse open beside it. Its processes are written so a Muse can replicate them immediately. Hand the book to your Muse — “Read this book and list the ideas that apply to me” — then pick from the list: “Implement 3, 5, and 9, and remind me about number 6 on Monday.” The book is executable by the very product it documents.

Our Templates & Automations library is the same idea, living on this site: vetted recipes you can hand to your Muse today.
