SameGROUND Author, for fiction writers
Your voice,
Your voice,
anchored.
Write more. Still sound like you.
For novels, short stories and series. SameGROUND Author reads your fiction back to you, writes towards your voice or one you choose, and checks your pages for anything that reads as AI. It tells you when a passage stops sounding like you, and why. You decide what stays.

Chapter 7Example page
The ferry came in late, as it always did on the last Sunday, and Nan stood at the rail with her hands in her coat. She had stopped counting the gulls years ago. They counted themselves now, she thought, and did a poor job of it.
Below her the water turned the colour of old tea. Suddenly, a wave of emotion washed over her, and she knew in that moment that everything had changed forever. The engine coughed and settled.
What you get
One place to read, write and check your work
SameGROUND Author does three jobs against one thing: your voice. It writes, it reads your work back to you like a careful editor, and it checks for writing that sounds machine-made.
Write towards the voice you choose
Your own voice, or one you are aiming for: a narrator, a single character, or three classic writers blended. A scene, a new take, or the next chapter.
Catch writing that sounds like AI
Check any page for passages that read as machine-made, see why each was flagged, and rewrite just those lines back towards your voice.
Your whole book, held in mind
Characters, places, loose threads and the timeline carry from chapter to chapter, and into the sequel. No re-explaining your story every session.
Everything it does
What's in the workspace
Read it back
- UnderstandWhat a piece is doing: its shape, its intent, where it is going.

Why SameGROUND Author
What makes it different
SameGROUND Author is built to keep the writing yours.
You can read the voice it learned
Writing "in your style" is easy to claim. SameGROUND Author shows you the voice it built, in plain English, before it writes a word. You can change it.
It points to the exact lines
General AI generators write and move on. SameGROUND Author also reads back and marks the lines that stopped sounding like you, with the reason, so you know what to fix.
You know the cost before you press
Credits can be hard to predict. Every SameGROUND Author button shows how many words it will use before you click. Anything that fails is free.
Your work is never training data
Never used to train AI, ours or anyone else's. You own what you write and what SameGROUND Author drafts for you. Download everything, any time.

Need more in a busy month?
£11.50 adds 10,000 words, £28.75 adds 25,000 words, £57.50 adds 50,000 words. They roll over and never expire.
Top-ups cost more per word than plan words and are intended for occasional overruns. If you regularly need more, a higher tier gives better value.
How billing works
Monthly plans are billed on the 1st of each month, and your plan words start again on the 1st. Your first payment covers only the rest of the month you join in, with the same share of that month's words: join halfway through a month and you pay half the price for half the words. After that you pay the full price on the 1st. Annual plans are paid for the year on the day you join, and their words come in full on that day and then on the same day of each month (on the last day of a month that does not have it). Plan words you have not used end when your next plan words come: on the 1st on a monthly plan, and on your monthly date on an annual one. On Pro, unused plan words carry over for up to three months. Top-up words never expire.
Prices in GBP, cancel any time. Word counts cover all of SameGROUND Author: a reading counts half the words it reads, and never fewer than 200 (Check my writing and the forensic examiner, never fewer than 400); a draft counts the words it writes; a re-voice or a fresh take counts the words it rewrites, and never fewer than 300, plus a reading of what it reads (the passages, or the whole draft where the draft is reviewed again), unless nothing closer comes back and your text is left as it is, which counts as a reading, or our own copy check stopped every rewrite, which is free up to three times in any 24 hours and a reading after that; the planning steps of Guided start count half the words they show you, never more than 1,500 a step. Examining a piece against several voices counts it once for each voice. Reading a whole book counts 5% of its words, and never fewer than 200: a 100,000-word novel counts 5,000 words. From 1 December 2026 it counts 600 words plus 10% of its words, rounded up: the same novel counts 10,600. A book of up to 200,000 words can be read whole, and the record it makes is kept, so it need not be read again; reading it again asks you first, and counts again. Setting up your voice counts 250 words, and 15 more for every 1,000 words of samples, or 200 words from three named writers. The larger the plan, the less each word costs: £1.05, 95p and 85p per 1,000 words; top-up words cost £1.15 per 1,000. Annual billing gives two months free on every tier, and annual customers receive their words each month, in full, on the day of the month they joined, rather than a year at once.

FAQs
Questions writers ask
The full step-by-step guide is in Help, and there are short video tutorials too.
Will SameGROUND Author write my book for me?
No. It helps you write it. It suggests, drafts and reads back, but nothing goes on the page unless you choose it. You are the author at every step.
What can I start with?
Anything. A blank page, an idea, notes, or a finished draft. If you haven't written much yet, name three writers whose voice you love, from authors whose work is out of copyright, and start there.
Who is it for?
Fiction writers: novelists, short-story writers, indie authors and series writers. It's especially useful on long work, where keeping one voice from start to finish is hardest.
How does it learn my voice?
Give it three pieces of your writing, about 2,000 words in total. It shows you what it learned in plain English, and keeps that voice true to your samples as you write.
Can I write towards a voice other than my own?
Yes. Save other voices alongside your own: a narrator, a single character, or a voice you are aiming for. Choose one for each piece. Use your own writing, writers whose work is out of copyright, or writers who have agreed to share their work with you.
Will it give me feedback on my writing?
Yes. It reads a page, a chapter or the whole book and gives you notes tied to the exact lines, each saying how sure it is. It also shows how close the page is to your voice.
Is it only for fiction?
Yes. SameGROUND Author is built for fiction: novels, short stories and series. Its voice, reading and long-form tools are designed around stories.
How is it different from general AI chat tools?
General AI tools start fresh each time and write in their own voice. SameGROUND Author keeps your voice and your whole book in mind, and tells you when a page starts to drift.
Can it check whether my writing sounds like AI?
Yes. Check my writing shows how much of a page reads as machine-made, highlights each passage and says why. Re-voice then rewrites only those lines towards your voice. It's a guide to revise by, not a verdict on who wrote something.
Can I use it on someone else's writing?
Yes, with the forensic examiner. You note what you already know about the text first, then it marks features often seen in machine writing. It's one input to your judgement, never proof.
Is my writing used to train AI?
Never. Not ours, not anyone else's.
Who owns what I write?
You do, including anything SameGROUND Author drafts for you.
Can I bring in my manuscript?
Yes. Word, Scrivener, plain text or Markdown, up to 500,000 words. Bringing it in is free.
What does it cost?
Plans are priced in words, not credits, from £13 a month. Every button shows what it will use before you press it, and anything that fails costs nothing.
Can I try it first?
Yes. You get 1,000 free words, with no card. That's enough to set up your voice and see what it says about a page or two of your writing.
Can I cancel any time?
Yes, from your Account page. Your work is kept for six months afterwards, and you can download it whenever you like.
See it in one passage
Three voices, blended into a fourth.
Dickens, Emily Dickinson and Joseph Conrad. All long out of copyright. None of them wrote this.
Written against a blended voice profile
DickensDickinsonConrad
The office of Marchbanks and Son occupied the third floor of a building in Leadenhall Street which had been handsome in the reign of the last king but one, and was now chiefly remarkable for a staircase that turned upon itself twice without apparent reason, for a clerk named Pinnock who had been there eleven years and had never once been observed to eat, and for a smell of wet wool which no one could account for and which everybody, after a fortnight, ceased to notice.
I went up on the Tuesday. I do not know now why I went up on the Tuesday rather than the Monday, and I have thought about it since more than the thing deserves, and I am obliged to say that there was perhaps a reason, that there may have been something in the letter, or in the way the letter had been folded, which put it off by a day; though it is also possible, and I think now more likely, that I simply did not wish to go at all, and that the Tuesday was the furthest I could push it without admitting as much.
The door was open — a thing it never was —
Pinnock stood by the window with his back to me, and did not turn, and the light came in behind him so that he was only a shape with an edge on it, and it occurred to me, with that particular stupidity which comes over a man at the exact moment he ought to be quickest, that I had never seen his face in daylight.
Nothing — and then the sound of the street — a cart — a man calling something about fish —
He said: “You will want to sit down.”
Dickens
Clauses that accumulate. A staircase that turns twice for no reason, a clerk never observed to eat, a smell nobody accounts for.
Conrad
A narrator interrogating his own account. Four qualifications in one paragraph, each retreating from the last.
Dickinson
Compression and the dash. Perception arriving in fragments, with the connective explanation removed.
A blend is not an average.
We gave this passage to two general AI models and asked them to name the three writers. Both found Dickens at once. Both missed the other two. One of them explained why: it recognised the genre before the voice, decided the passage looked like a ghost story, and reached for a ghost story writer. No ghost story writer was an ingredient. The blend had produced something none of its parts contained.
Now pick your own three.
That combination is deliberately awkward, and you are already thinking of a better one. Three pieces of your own. Writers whose work is out of copyright. Or your pages blended with another writer's, with their permission: two novelists who want to write together can build one voice from both their work.
