Harry Potter fanfic,generated from the premise only you have.
Marauders-era mischief, a Sorting Hat that refuses to choose, the war ten years later seen from the ruins of the Room of Requirement. You name the era and the premise, and you get a chapter in a voice that fits it. Book canon carries it. Your canon goes in the Story Bible, and every chapter after that respects both.

For your wizarding fic
Canon in a drawer
Your house lore, family trees, OCs and rules live in the Story Bible. The AI checks them before it writes another line of your chapter.
Era-appropriate voice
Marauders banter reads like Marauders banter. You say the era and the tone; your draft follows both.
Ship it or OC it
Canon pairings, original characters, or the pairing you have been maintaining alone for years. All of them survive a hundred chapters.
Chapter by chapter
One-shots or full serials, saved as your project and exported as one document when your fic is done.
Example: "the Sorting Hat refuses to sort a student"
The Hat had been on the girl's head for four minutes. The Great Hall had progressed from whispering to the particular silence of four hundred people pretending not to lean forward.
"Well?" said McGonagall, quieter than she had ever said anything. Under the brim, the Hat was having the first argument of its thousand-year life, and losing. "Any House," it said at last, "would be a mistake."
A sample of the shape these pages aim for; yours is the one with your fandom in it.
Questions
Does it get Harry Potter canon right?
It knows the books well, and your version better once you teach it. Put your headcanons, OCs and divergences in the Story Bible, and every reply is checked against them.
Can it write full-length fics, not just scenes?
Yes. Your chapters build up in one project, so a serial works the way AO3 serials do: one update at a time, with help when you get stuck.
Is the generator free?
Free to start, no credit card. You write on the free plan every day; upgrading just adds more pages.
Can I use my own characters?
That is half the point. Introduce them in your prompt or the Story Bible, and they stay consistent: same voice, same relationships, same secrets.
Can it do ships like Dramione or Wolfstar?
It writes any pairing you ask for, canon or otherwise, at the heat level you set in words like "slow burn" or "already together, domestic".
