No thanks, I'll reread every chapter myself and hope I catch everythingA character you killed in chapter 9 turns up in chapter 31. "Corvin" becomes "Corwin". A prisoner strolls through the market. One word shows up four times in a paragraph. Readers notice, and some of them say so in reviews. You only find these slips by rereading everything, again and again. Premium does that first pass for you.
The checker and scanner are rule-based: they compare your manuscript with the characters and places you've set up, and look for repeated words. The Prompt Hub builds prompts you copy into ChatGPT, Gemini or Claude using your own account. You stay the author.
One click compares your whole manuscript, or a single scene, with your Characters and World Atlas. You get a Manuscript Health score and a list of every slip, sorted by severity, with the scene it's in.
Works best on English text. It checks names, statuses and places, not the meaning of every sentence, so you still make the final call.
Repeated words are invisible to the writer and obvious to the reader. Flat rhythm makes a gripping scene feel like a list. The scanner finds both, so a polishing pass takes minutes instead of days.
The shadows stretched across the courtyard as the bells fell silent. Elaseth watched the shadows crawl toward the gate, and in the shadows she saw the shape of a man.
If you draft or edit with ChatGPT, Gemini or Claude, the hard part is explaining your book every single time. The Prompt Hub packs your Story Bible, cast, place and scene into a ready-made prompt you copy in one click. No more re-typing your world.
Ocean Novel doesn't connect to any AI service and adds no AI fees. You paste the prompt into your own AI account and review what comes back.
