Gnothi AI
Your book, a chapter at a time
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Name a subject or let your journal pick the lesson. Gnothi writes you a book, one chapter at a time, as a course or a story. Read it or listen. About a dollar a chapter.
Gnothi writes you a book, one chapter at a time, about something you're learning or your own life. You pick the lesson, or your journal does. Read each chapter or listen to it.
WHAT IT DOES
• A story that teaches. Pick a subject and a world, and the lesson happens in the plot: the story's problem needs the skill, and how it turns out depends on how it's used. Or take it straight, as a course with a syllabus that remembers what it covered.
• Your journal steers the next chapter. Write where you got stuck, and the next chapter takes it up. Told straight, a chapter names what's in the way and often ends on a step you can start today.
• Friends as characters. When friends share entries with you, your story can cast them.
• Apple Watch. With AI on, say "dentist appointment 3pm Saturday" and it becomes a to-do. Log habits, dictate a journal entry, or start new chapters in the books you pick.
• MCP server. Connect Claude or another MCP client to add and check off to-dos, log habits, and read or write journal entries.
• Fields, from the creator of Habitica. Habits, dailies, to-dos and rewards you buy with gold. A chapter can check in on a habit that's slipping.
• Read or listen. Every chapter comes narrated, about half an hour each, and your book reads on an e-reader too.
ALSO
• A journal with dictation, AI titles and summaries, and chat over your entries.
• Groups, with an anonymous petname in each.
• Causal analysis (PCMCI) that finds which of your fields likely drive others.
AI features stay off until you turn them on.
PRICING
Free to start, with starter credits. A chapter costs about a dollar in credits, bought as one-time top-ups. No subscription.
Apple Watch improvements: when Do it can't match what you said, it adds it as a to-do. In the app, To-Dos can hide finished items, and chat history shows your earlier conversations. Plus fixes.
