How to Use the Writing Coach in the Writing Studio

The Writing Coach asks questions, gives feedback and ideas, and can draft a section in your voice if you ask. Connect your own AI key once to begin.

The Writing Coach is your AI helper inside the Writing Studio. By default it coaches: questions, feedback and ideas. If you ask it to write or draft a section, or part of one, it will do that for you, in your voice. Click Writing Coach next to the Visual Editor and Page Preview tabs to open it.

What does the Writing Coach do?

By default it coaches: questions, feedback, ideas. Once a key is connected, the coach sees the current section and its Writer's Prompt and can give specific feedback.

If you ask it to write or draft a section, or part of one, it will do that, in your voice, from your book details and the draft so far. Then it invites you to adjust it. On the Step 4 · WRITE roadmap page, the Writing Team list says "Coach, edit & polish as you go," and the Writing Coach is described as ideas and feedback, with a draft of a section if you ask.

How do I connect my AI key?

The Writing Coach requires a personal Claude, Gemini or ChatGPT (OpenAI) API key. This is a one-time setup. Connecting is super easy. It takes only a few seconds, and the app guides you through it step by step.

1. 1Click Writing Coach ▼ to open the panel.
2. 2Click Connect Claude →, Connect Gemini → or Connect ChatGPT →.
3. 3Follow the instructions in the setup panel.

Using your own key is free or costs very little. Gemini has a free tier. The connected key is saved with your account and used through the app's server to call the provider you selected. Never paste a secret key into the coach chat. The same setup also covers the Section Editor and the Final Editor. Connect once and all three work.

Where to get each key:

• ✦Claude: console.anthropic.com
• ✦Gemini: aistudio.google.com
• ✦ChatGPT (OpenAI): platform.openai.com/api-keys

When a key is connected, the Writing Coach button shows a small coloured dot (●).

Can I speak to the Writing Coach?

Yes. The Writing Coach has a voice input button (a microphone icon), so you can speak your questions instead of typing them.

How do I switch between Claude, Gemini and ChatGPT?

Whichever provider you pick here also becomes the default for the Section Editor and Final Editor. Each of those has the same Claude, Gemini and ChatGPT toggle, so you can switch per tool if you have connected more than one key.

How do I change my key later?

Click the small ⚙ change link at the bottom of the Writing Coach panel.

Can I make the coach sound like me?

Yes. Under the Writing Coach panel there is a 🎙 My writing voice link. See How does My Writing Voice work?.

Can I use my ChatGPT subscription?

Not directly. A ChatGPT Plus or Pro subscription is separate from OpenAI's API. To use ChatGPT here, create an API key at platform.openai.com/api-keys, with billing set up there, and connect it with Connect ChatGPT →. See ChatGPT subscription or API key?.

What does an out-of-credits message mean?

If your key works but the account has no credits, the coach panel says so and links to that provider's billing page. For Gemini, the message says its free limit resets within 24 hours, or you can add billing at aistudio.google.com. This is about the provider's account, not something broken in the app. See What do I do if I run out of credits?.

Do I need to tell Amazon if I used AI?

KDP asks authors to say when text was AI-generated at publishing. Read Can you publish AI books on Amazon KDP? and the KDP content guidelines.

Not sure where to start? The Course Coach inside the app guides you through each step, so you are never stuck on a button.
