Notes on your whole novel, right where they matter
BetaVault is an AI reader. It reads your full manuscript and leaves notes at the exact passage where pacing drags, a character slips or a reader would stop. It never writes or rewrites a word of your book, and it runs on our own servers, so your book is never sent to OpenAI, Google or Anthropic.

Chapter Seven
The kettle had gone cold by the time Nell found the letter. She read it twice, then a third time, as if the words might rearrange themselves into something kinder.1
1Works
The rereading shows her denial without stating it.
Outside, the harbour lights came on one by one, the boats knocked against the pier, gulls wheeled over the empty fish market2 and the rain kept on as it had all week.
2Pacing
Four images in one sentence stall the moment right after the letter. Keep one.
“You knew,” she said when Tom came in. He set his keys down on the table and said nothing at all.3
3Character
Tom has talked his way out of every scene so far. This silence needs setup earlier.
The problem
Feedback is slow, expensive or vague
Beta readers often take your book and never write back.
Developmental editing can cost more than you'll earn from the book.
Summary reports tell you what's wrong without showing you where.

Questions
Is BetaVault available now?
Not yet. We're building it now. Join the founding list and we'll email you when it's ready, with your founding price locked in.
Will I be charged if I join the list?
No. Joining the list is free and doesn't commit you to anything.
Is this just ChatGPT?
No. It runs on open models on hardware we own, so your text never goes to ChatGPT or any other AI company. It is AI feedback, though, so read your free sample and judge it for yourself.
Will it just flatter me?
It's built to find problems, not to praise. If the sample doesn't tell you something useful, don't buy a full read.
Does this replace a human editor or beta readers?
No. It's a fast, private first read so you can revise before you spend money on an editor or send pages to agents.
