An iPhone app for one great aim
Decide exactly what you want. Return to it every morning and every night. Do the work in between, with a Master Mind at your side. SYNTHARON is the daily operating system for Napoleon Hill's method, built for iOS 26.
The promise
SYNTHARON makes all three effortless to start and very hard to quit. Not with hype, but with a ritual you can measure, a plan you can revise, and people who expect you to show up.
Personal development built on your own effort. Results depend on your circumstances and the work you put in. SYNTHARON makes no income or health claims.
01 / The daily system
Three parts to every day. Each one is short, concrete, and leaves evidence behind.
"Tell the world what you intend to do, but first show it."
02 / The 91-day Path
Hill's thirteen principles, in his order, one lesson and one exercise a day. Unlocking a step is a ceremony, with Hill's line and a narrated reveal.
Clarity before intensity
A definite purpose gives your attention a direction. Make it specific, give it a date, and decide what you will contribute in return. In the app, Ignimani pushes back on vague aims until yours is exact.
03 / Ignimani and the Council
AI feature · clearly labeled in the appIgnimani is the AI coach. It is on every screen behind one ember button, reads your Dossier so advice is specific, names the bottleneck in your weekly plan review, and gives you one to three concrete moves. It will not flatter you.
The Council of Invisible Counselors is Hill's own practice of imagined counsel, made usable. Ask one counselor, or convene three to five: each answers in character, they debate briefly, and the chair synthesizes a recommendation with next actions. A short Nightly Cabinet session closes the day.
Every counselor is an AI persona inspired by the publicly known ideas of a historical figure. None is the real person, none claims to be, and none uses a real likeness. You can add your own counselors, archetypes or historical figures, under the same rule. Read what the AI is and is not.

"What is the single outcome that would make the next ninety days meaningful?"
Curated example prompts. No live AI runs on this website.
04 / Mastermind groups
"The Master Mind may be defined as: coordination of knowledge and effort, in a spirit of harmony, between two or more people, for the attainment of a definite purpose."
Two to eight people. One weekly meeting. Every commitment tracked.
Create an invite-only group, set its purpose, and share your aim with the people in it if you choose. The group has a feed, chat and voice notes, a shared calendar synced to iOS Calendar, and a scoreboard: total Forge hours, member streaks, commitments kept.
Meetings run on SYNTHARON's own video calling, not FaceTime. They ring like a real call, support picture-in-picture and screen share, and follow a Hill-style agenda shown live: wins, commitment check, hot seat, ideas round, new commitments.
An optional AI Facilitator joins as a participant to keep time and prompt each segment. Afterwards it writes the summary, the decisions, and each member's commitments, which drop straight into their plans with due dates. Recording and transcription only happen when every participant has accepted a clear on-screen consent prompt.
An accountability partner, the one-to-one version, is also included: they see your streak, Forge hours and misses according to your settings, and can send a nudge.

Before you begin
Hill's word for deliberately feeding your own mind a chosen idea through repetition, with emotion, until it shapes behavior. In SYNTHARON it is a measured practice: you read your statement aloud morning and night, the app verifies the recitation, and the reading is paired with a plan and real work. It is not a promise that repetition alone changes anything outside you.
No. SYNTHARON is an independent product built on the 1937 edition of Think and Grow Rich, which is in the public domain in the United States. It is not endorsed by, sponsored by or affiliated with the Napoleon Hill Foundation or Hill's estate. Every quotation on this site and in the app is drawn from that 1937 text.
No. Each counselor is an AI persona inspired by the publicly known ideas of a deceased historical figure, labeled as such in the app, with no photographs or real likenesses. If you add a counselor based on a living person, it is built as an archetype shaped by that person's public ideas and framed openly as imagined counsel. See What the AI is and is not.
No app can promise that, and this one does not. SYNTHARON helps you decide what you want, plan for it, do the work daily and stay accountable. Outcomes depend on your aim, your circumstances and your effort. Ignimani and the counselors do not give personalized financial, legal or medical advice.
