Help that knocks. Not a ghostwriter with a key to your house.
Most AI writing tools treat your chapter like a draft they already own. CoAuthor suggests. You decide. That is the whole product.
The mess
The paste loop is humiliating and it does not scale
Copy chapter into ChatGPT. Lose the cast. Paste back. Fix the voice. Repeat until you hate writing.
- Context windows that forget the villain's name
- Tools that rewrite half the page without asking
- Output that sounds like every other model output
- A master file that is actually a chat log
What you get
Same desk. Propose only. You keep the pen.
CoAuthor sits next to the chapter with binder and bible context. Suggestions show as proposals. Accept. Reject. Move on.
- Lives in the manuscript, not another tab
- Sees structure and continuity tools when you open them
- Propose-only by default
- Optional. Never required to write free
How
Do this in order
Not a feature tour. The actual path.
- 1
Open the stuck chapter
CoAuthor is sharpest on a real scene, not a blank vibes prompt. Put the cursor where the draft died.
- 2
Ask for a job, not magic
Unstick a beat. Check continuity. Try a line of dialogue. Name the constraint: POV, tense, what must not change. Vague asks get vague sludge.
- 3
Read like an editor, not a fan
Proposals can be useful and still wrong. Check voice. Check facts against the bible. AI is confident. Confidence is not canon.
- 4
Accept or reject. No drama.
Keep what earns a place on the page. Trash the rest. If you enable any auto-accept preference later, that is still your choice and your responsibility.
- 5
Write the truth into the bible
When a detail becomes real, file one line in the story bible. That is how continuity survives the next session.

Questions
Straight answers
Will CoAuthor overwrite my manuscript?
No. Propose-only is the product stance. You accept or reject every suggestion.
Do I need Typewriter Pro to use CoAuthor?
No. Free desk for writing. CoAuthor is its own plan ladder from $9/mo. Pro desk unlocks bible and map depth.
Do you train on my book?
We do not train our models on your private manuscripts for other customers. Inference uses context when you run AI. Full detail in Privacy.
