Sgeulai Pro

Sgeulai is free to download and free to keep using. Sgeulai Pro is one purchase, once, that unlocks the rest of it. There is no subscription and no trial period to run out: the free side of the app doesn't expire, doesn't count your words, and doesn't stop letting you write.

Open it from the Sgeulai menu ▸ Sgeulai Pro…. It also opens by itself when you choose something that is part of Pro, with a line at the top naming what you chose — Draft Here is part of Sgeulai Pro.

What stays free

All of the writing, and all of the Story Bible:

What Pro adds

FeatureWhat it does
Continuity Check, on the whole bookTwenty rules read the entire manuscript against your Story Bible, and mark the findings as you write. Checking one scene stays free.
Canon FixesChange an attribute in the Story Bible and carry it into every passage that still says the old thing — one sentence at a time, ticked by you, and never swept.
Ask Your BookAnswers a question about your book from the Story Bible and the manuscript, and quotes the passage it read, with a link that lands on it. An answer it can't trace to your own words isn't shown.
Draft Here and Rewrite Selection Drafts a passage at the cursor, or rewrites the one you selected, from your Story Bible — checked against the book before you see it. See Reading the manuscript with AI.
Previously in the seriesWrites what happened in the earlier books as of the moment this one opens, holding back anything your reader hasn't reached yet. Your own summaries, no AI.
Submission PackWrites the pitch, synopsis and series bible an agent asks for, then runs each one through the continuity rules before you read it. A synopsis that invents a character doesn't reach you.
The tools that judge the bookFamily Tree, Cast Grid, Loose Ends, Spine Report, Five C's, Voice Check, Scene Shape, Thread Map, Pacing, Paragraph Profile, Readability Comparison, Vocabulary Index, Style Report, Series Continuity and Character Arc.
Everything an agent asks forExport for Vellum, styled ePub, PDF, tracked changes, Scrivener, Plottr, spoiler-safe canon, the Story Bible reference, and the AI provenance and disclosure reports.
Apply PseudonymsSwaps real names for manuscript names across the prose. Restoring the real names is always free, whatever you own — undoing something the app did to your words is never something you have to buy.
Analysis with ClaudeThe deeper passes that read your manuscript with Claude. See below about what those cost.

Check This Scene, which is free

Tools ▸ Check This Scene checks the scene you are working on against your Story Bible — an appearance the Bible contradicts, a real name left behind a manuscript name, a link to the wrong kind of record, an age the scene's date won't allow. It is free, unlimited, and uses the same rules on that scene that Pro uses on the whole book, so it does not give you a second opinion: it gives you the same one, about less of the book.

Choosing Continuity Check in the binder without Pro runs that same check and shows you what it found, with the case for the whole-book version underneath. What one scene can't show you is the rest: a setup you never paid off, a character still alive two chapters after they die, a journey the dates don't allow.

Locks in the binder

A tool that is part of Pro carries a small lock beside it in the binder, so you can see what is included before you choose it rather than after. Continuity Check has no lock, because that row does something free.

What Pro does and doesn't pay for

The features that read your manuscript with Claude need your own Claude API key, or Apple's on-device model where that is available. Pro doesn't pay for those runs — Anthropic bills your key directly. The app shows an estimated price before it sends anything, and stops at a spending limit you set. Continuity Check, Check This Scene, Canon Fixes and Previously in the series use no AI at all and cost nothing to run.

Whether you already have it

The window says so: Sgeulai Pro is unlocked for this Apple Account. It is a one-off purchase on your Apple Account, and it is shared through Family Sharing like any other.

Buying it

The button carries the price: Buy Sgeulai Pro — and whatever your App Store charges in your own currency. Clicking it hands over to the App Store, which asks for whatever it usually asks you for, and the window changes to the unlocked line when it's done.

Restore Purchases, beside it, is for a Mac that hasn't caught up — a fresh install, a new machine, a different account signed in while you bought it. It asks the App Store again and costs nothing.

If the window says Sgeulai Pro isn't available from the App Store right now, the app couldn't reach the store. Try Again asks once more. Nothing has gone wrong with what you own, everything you have written is unaffected, and the free tools keep working.

What you own

Sgeulai Pro is a one-time payment, not a subscription. Nothing stops working because you stopped paying, because there is nothing to keep paying.

On the iPad

It's one purchase for both: buy it on either, and the other unlocks when it next checks with the App Store. You are never asked to pay twice for moving between them.

Three Pro features are on the Mac for now — Draft Here, Rewrite Selection and Continuity as you type — and the iPad's own Pro sheet says so beside each of them. They follow in a later release, free to anyone who already has Pro.

The iPad has no menu bar to open the sheet from: reach it from Settings ▸ Sgeulai Pro, or by choosing something that is part of Pro. That is also how you reach Restore Purchases there.
