— know before you publish —

A hundred thousand words, and nobody has read to the end

Get one reader, or a group, to read your book a day at a time — each remembers yesterday and may not open it tomorrow. You find out whether the book gets finished, which chapter readers leave at, and the line where each one stopped.

Get started now

The hard part after finishing a book is finding one person who reads from chapter one to the end. Friends will read a chapter; almost nobody follows a whole book. Post it to a forum and readers only tell you whether chapter one is any good. LitMemo's AI beta reader report has one reader persona (a group on paid plans) follow your book the way a serial is followed: 10,000 words a day, then a note of what they still remember tomorrow, then the next day read with that memory — and when they stop wanting to read, they stop opening it. When it's done you know three things: how many finished, which chapter lost the most readers, and the exact line where each one stopped. Every finding carries your own text, so one click puts it back on the manuscript to revise against. It deliberately does not give you a 1-10 score — we measured that score ourselves and it doesn't hold up. That's explained below.

"It's done… and even I can't tell whether anyone would still be reading by chapter five."

You're too close to your own draft — by the seventh pass, the first-time experience is gone. Far fewer people will read a whole book than a single chapter, and the one thing that would actually help is "I stopped opening it at chapter five" — which almost nobody will say to your face.

I

A day at a time, remembering yesterday, maybe not opening it tomorrow

A reader reads 10,000 words a day. Afterwards they write, in their own words, what they will still remember in the morning: where the story is, who they've met, what they're waiting for, what they didn't understand. The next day they read with only that memory — what they forgot stays forgotten. When a thread planted in chapter three is gone by chapter five, the report says plainly "this reader didn't remember it", and that is your signal about how firmly the thread was planted. When they no longer want to read, they stop opening the book: the remaining days are not read and not charged. A 74,000-word book is 8 days for them, and you don't have to sit and wait for it.

  • Each day ends with a note: remembered, waiting for, didn't get
  • Stops opening the book — the rest is not charged
  • 74,000 words is 8 days, and you are notified when they finish
II

It opens with a verdict: how many started, how many finished

The first line of the report is "5 started reading, 3 finished", followed by how many are still reading at each chapter, the chapter that lost the most readers, and the line where whoever put the book down that day stopped. Below that comes each reader's diary: for every day, how far they got, what they remember, what they're waiting for, whether they'll open it tomorrow — all in the reader's own words. The manuscript diagnosis is a separate judgement that never sees the reader persona and is shared by every reader — you can write your own readers, but you can't write the verdict. No 1-10 score, on purpose: we measured it 140 times on five real manuscripts and that number could not tell the drafts apart, and a number you can't verify only makes you revise the wrong passage.

  • Retention: how many are still reading at each chapter
  • The chapter that lost the most readers, and the line they stopped at
  • Each reader's diary, printed in their own words

Then take it straight back to the manuscript

The least useful shape for a report is a PDF you read once and close. The main action here is "go see where they caught" — each finding anchors back into the editor by quotation, so you revise with the reader's reaction beside you. Anchors follow the quote: insert a passage earlier and everything shifts, and it still finds its line; rewrite that passage and it says "you've already revised this" and retires. Serial authors publish a chapter and the same readers pick it up with their memory intact, paying only for the new day.

  • Findings anchor into the editor, revise in place
  • Revised passages retire themselves — no stale advice
  • Add a chapter, the same readers keep going

Have you run into this too?

「The book is finished and you want to know whether it gets finished, with nobody willing to read from chapter one to the end」

Start one reader at chapter one, and a few minutes later you have "finished" or "stopped opening it on day 5", plus the line where they stopped. No begging a friend to read a hundred thousand words, no posting the whole manuscript in public.

「You're serializing, just posted a chapter, and want to know whether the readers who got this far are still with you」

The same readers pick up the new chapter with last round's memory, and you pay only for this chapter. Whether this chapter delivered what they were waiting for, and whether anyone still remembers the thread from chapter three, is right there in their diaries.

「You just finished a chapter and only want to know if this one holds」

Pick just that chapter — one chapter is the reader's day 1. Later, when you want them to go on, they continue from where they stopped, memory intact.

Get started in four steps

  1. 1

    Pick how far

    Choose the chapter to read up to — one chapter or the whole book

  2. 2

    Pick who reads

    One reader starts at chapter 1; paid plans can bring a group, or let last time's readers continue

  3. 3

    Start

    Day 1 is charged first, then each day as it's read; if credits are used up it pauses and resumes when you top up. You can leave the page

  4. 4

    Take it to the draft

    You'll be notified; open the report and put the line each reader stopped at back in the editor

Frequently asked questions

Three things. It reads the whole book: 10,000 words a day, then the next day with the memory it wrote down itself, so a comment on chapter eight knows what happened in chapter three. It gives no score: we measured it ourselves — one reader persona gave five completely different manuscripts the same score, and asking again changed it. And it answers questions you can verify: how many finished, which day a reader stopped opening the book, which line they stopped at — every one of them checkable against your own manuscript.

Part of it. At the end of each day the reader writes, in their own words, what they will still remember in the morning: where the story is, who they've met, what they're waiting for, what they didn't get. The space is fixed, so older things fade. The next day they read with only that note, so a thread planted in chapter three may be gone by chapter five — and the report will say "this reader didn't remember it". That is a signal about how firmly the thread was planted. The memory belongs to the reader: the report says whether they remembered, and leaves the judgement of whether you planted it to you.

On FREE, one reader reads your book to the end. Paid plans bring a group (5 to 12 readers depending on the plan), and a group is what separates "everyone left at chapter five" from "one person didn't like it". You can add readers midway when there's a seat; newcomers read in the same round as everyone else. The attention heat map (each reader's engagement across the text, day by day) and custom readers are MUSE capabilities; custom readers shape the reactions, and the manuscript diagnosis never sees the persona.

One reader, one day (10,000 words; characters for Chinese and Japanese text) is 4 credits — multiplied by days and by readers. The total for the round is shown before you start; a 74,000-word book read to the end by one reader is 31 credits. Each day is charged just before it is read and returned if that day is not finished; days a reader never opens are not charged. If credits are used up, the reading pauses where it is, and topping up resumes it with the memory intact. You can close the tab; you'll get an in-app notification when it's done.
