Conjure the story. Keep the pen.
Prospero is a home for fiction made with open AI models, and for the people who read it: quick fun stories and fanfics, or serious novels built step by step, with honest labels on how each was made.

A library and a writing studio
Named after Shakespeare’s magician in The Tempest, who conjures a whole story on his island and knows exactly what his magic is. Browse every genre and subgenre, follow writers, and make books of your own.
Genres and subgenres
Cozy fantasy, romantasy, clean dystopia, post-apocalyptic, solarpunk, cosmic horror, cozy mystery, fanfic of your fandom and dozens more.
Prep phases you control
Premise, characters, world, voice, outline: rename, reorder, skip or add phases, and draft each with AI or write it yourself.
Quality prose mode
Open-weight models write; a stronger model hunts AI habits (stock phrases, flat rhythm, em-dash storms) and you refine with one click or your own words.
Honest AI-share labels
Each book can carry a label measured from what you really did, from “AI prose” to “Human-written”.
Free or paid chapters
Originals can mix free and paid chapters. Fanfiction is always free.
Yours to sell
Export with a disclosure and sell your originals on KDP or anywhere else.
Marble spark
Awakening
VeilThe statue that came to life
In Ovid's Metamorphoses, Pygmalion's statue grows warm and breathes. On Prospero, Galatea is your fellow writer and editor.
- Talks craft like an editor — structure, tropes, character arcs, pacing, and why a sentence sounds machine-made.
- Brainstorms with you — premises, twists, names that aren’t Elara or Kael, and what your villain really wants.
- Improves your posts in the Community, in your own voice and language.
- Paints covers and scenes — describe it and she draws it in watercolour, ink, oil or poster style, marked ✦.
- Never acts alone — you approve everything, and AI-assisted work is always marked ✦.
Read like Wattpad. Write like a pro.
The Library for readers, the Studio for writers, and a Community around both.
📚 The Library is home
Open Prospero and you land in the Library, like Wattpad: shelves of most-loved and new books, genre tiles, and a shelf for every genre.
📖 Read chapter by chapter
A clean reader with a cover page, blurb, likes and chapters. Paid chapters show a preview first.
🪄 The Studio, one tap away
Start a book in Fun mode (an idea, a genre, go) or Serious mode with the full prep phases.
✒ Quality prose mode
A writer model drafts, a stronger checker model hunts AI habits, and the writer revises before you see it.
🔍 The AI-habit checker
Every chapter gets a prose score and a list of stock phrases, flat rhythm and em-dash storms to fix.
✦ Refine with one click
Remove AI habits, vary rhythm, show don’t tell, sharper dialogue, tighten, more vivid, or ask in your own words.
🏷 Honest AI-share labels
Measured from what you actually did: your idea, prompts, prep and how much AI wording survived your edits.
💬 Community
A calm feed for writing talk, prompts, challenges and sharing your chapters. Follow writers, message, join groups.
🛡 Safe by default
No ads, no tracking. Report and block on everything, and your books and data are yours to download or delete.

Prospero on your phone
Install Prospero like an app — its own icon, full screen, no store needed. It always stays up to date.
- Open Prospero in Chrome on your Android phone: open the app.
- Chrome shows "Install app" at the bottom — tap it. Or open the menu ⋮ and choose Install app (or Add to Home screen).
- Tap Install. The Prospero icon appears on your home screen — open Prospero from there, full screen.
Prefer a download? The Android app file (APK) will be available here soon — you'll allow "Install unknown apps" once, and Android installs it.
- Open Prospero in Safari on your iPhone or iPad: open the app.
- Tap the Share button (the square with an arrow ↑) at the bottom of the screen.
- Scroll down and tap Add to Home Screen, then Add.
- Open Prospero from your home screen — it runs full screen, like an app.
On iPhone this works in Safari. In other browsers, use Safari for this one step.
Two ways — choose the one you like.
Option 1 · Add to Dock Recommended
Nothing to install, updates itself, notifications work. Needs macOS Sonoma (14) or newer.
- Open Prospero in Safari: open the app, and sign in.
- In the menu bar choose File → Add to Dock… and click Add.
- The Prospero icon appears in your Dock and Launchpad — Prospero opens in its own window.
Chrome or Edge work too: menu ⋮ → Cast, save and share → Install page as app.
Option 2 · The Prospero Mac app
⚠️ Made by Prospero's founder and not yet verified by Apple. It's safe — a small window for Prospero, nothing else — but because Apple hasn't checked it yet, your Mac asks you to confirm the first time you open it.
⬇ Download Prospero for Mac 1 MB · Apple Silicon and Intel · macOS 12 or newer- Open the downloaded zip (in Downloads) — it unpacks Prospero. Drag it into your Applications folder.
- Double-click Prospero. Your Mac says it can't check it — click Done (or Cancel).
- Open → System Settings → Privacy & Security, scroll down and click Open Anyway next to “Prospero”, then confirm with your password.
- That's it — from now on Prospero opens normally. Sign in with Google and you stay signed in.
On older macOS (12–14) you can also right-click Prospero → Open → Open. Updates: the app always shows the latest Prospero — you only download it once.
- Open Prospero in Chrome or Edge: open the app.
- Click the install icon at the right end of the address bar (a small screen with an arrow), or menu ⋮ → Cast, save and share → Install page as app.
- Prospero opens in its own window and appears in your Dock or Start menu.
Questions
Is Prospero really free?
Yes. Posting, following, pictures, documents, themes and the daily Report are free. Paid plans add more Galatea and keep the platform independent.
Does Galatea post for me?
Never on her own. She drafts, improves and plans — you read, edit and approve every message. Galatea-assisted messages carry ✦ so everyone knows.
I don't fiction — can I join?
Of course. Prospero is for readers too: browse, love and follow without ever writing a word.
Is there video?
Not yet. Prospero focuses on posts, pictures and documents for now — calm and fast on any phone.
How do I sign in?
With your Google account. There are no passwords to remember, and every account belongs to a real email.
What happens to my data?
It's yours. No ads, no selling of data, and you can download everything or delete your account at any time from Settings. Read the privacy page.
Can my studio or company use it?
Yes. Writing groups, classes and small presses can use it; paid plans give more and stronger AI.
