Small words can carry a date.
Philadelphia, 1776: “She zipped her cloak against the wind. ‘Okay,’ she told her brother, ‘we leave at noon.’” Two details would stop a reader who knows the period. Zippers came more than a century later, and “okay” first appeared in print in 1839.
Let history lovers settle into your story.
One wrong detail can pull a reader out of a scene you worked hard on. Here is what changes for you.
Your characters sound like their century
You can stop wincing over whether a phrase or a mindset belongs, because your people speak and think as someone of their time would. When a character is meant to be ahead of their time, that stays your call.
Your world feels lived in
Your story’s rooms, meals, and journeys, and the real events and people it touches, can all ring true. You swap in something that belongs and keep the scene moving, and you confirm the big facts with reliable sources.
The odd detail you love stays
A rare but true detail does not have to cost you a reader. You keep the surprising choices you made on purpose, and every final call stays with you.
Research stops feeling endless
A vague worry about the whole book becomes somewhere to begin. You spend your hours where they count and get back to your story sooner.
When a second look pays off.
Pick the moment that sounds like yours, and you decide what changes.
The week before beta readers or your editor
You want their attention on your characters and your plot, not on a stray modern word. Clear the period slips you can handle yourself, and spend the conversation on what only they can tell you.
The night before you query or submit
Your sample chapters carry your whole first impression. Give them one last period pass, so an agent or acquiring editor meets your story. No one can predict how they will respond.
The day you reopen a backlist title
A new edition, a new cover, or a series relaunch brings fresh eyes to an older book. Fix what you can while the file is already open.
Bring the book you are revising.
You bring
Upload your manuscript or the chapters you are working on, then enter when and where the story takes place and its genre as specifically as you can, such as “Regency romance” or “1930s small-town mystery.”
Your manuscript stays private. Author Media never stores or views it, and the AI companies do not train on it.
You get
A written review that points to passages worth a second look, explains why, and suggests a period alternative where one fits, with the chat open for your follow-up questions.
Treat the review as revision help. It works from the AI’s historical knowledge, does not search the web or cite sources, and can miss a problem or question a detail that was correct. Verify consequential facts with reliable sources before you change your book.
Before you start
What is Historical Fact Checker?
You love your era and want readers to trust it. If you write historical fiction, historical romance, alternate history, or any story set in a real past, Historical Fact Checker is the AI revision tool that helps you catch anachronisms while you revise.
Does it replace my own research?
No, and your research still matters. You get a place to start, so your time goes to the details that matter most instead of the whole book. It does not search the web or cite sources, so confirm consequential facts with reliable sources or a historian, and do not treat the review as proof that your book has no errors.
Can I use it for alternate history or fantasy?
Yes, and your invented world stays yours. Mention your premise when you describe your book, and you decide which real-world details your world keeps.
My story covers many years. Can I still use it?
Yes, and a long saga can still get a steady read. Bring each era’s chapters on their own, with that era’s starting year, and each one gets its own steady read.
Is there help for medical, military, or local details?
A scene that leans on an injury, a battle, or a real street deserves a specialist’s eye. Medical Fact Checker is there when you want an injury and its recovery to ring true, Military Fact Checker when you want your soldiers and their weapons to feel real, and Local Fact Checker when you want a real street to feel right for its year.
Does it check grammar, pacing, or plot?
No, which keeps your attention on one job at a time. For story and structure, try Not a Developmental Editor, and for spelling and grammar, try Not a Copy Editor.
Can I use it for historical nonfiction or memoir?
Yes, and a true story deserves the same steady care. You can use it to spot passages that deserve a second look. It is built for fiction, so verify claims against original records and reliable sources. It does not authenticate sources or replace a publisher’s fact-checking.
Is my manuscript private?
Yes. Author Media does not store, track, or view anything you post to this tool. The tools reach each AI through its business API with privacy set to the maximum, so the AI companies do not train on your words.
