Not just “ask ChatGPT”

Your key pays for the AI.
Our method tells it what to write.

Ask any AI for a BookTok hook and you get something that could be about any book. The studio gives the AI our own hook method: what to lead with, what a stranger needs to know, where to stop. It’s built from slideshows that actually performed, along with rules for picking moments, trimming the page and colour-coding dialogue.

Asking an AI yourself
“In a world of power and danger, one arranged marriage will change everything. 🖤”

Sounds like a movie trailer. No characters, no detail from your book, nothing to make a stranger stop.

The studio, same book
“When your coward brother pays off his forty-million-dollar debt by marrying you off to the most feared mafia boss in the city…”

Who they are to each other, the premise, and a turn that makes you need the next slide.

Bring your own AI

Your AI account. Your book. Nobody in between.

The studio runs on your own AI key. The AI company bills you directly for what you use, usually cents, and there’s a free option. We never see your bill, and we never keep your key or your book.

What’s an API key?

A code that lets the studio use an AI on your account. Getting one takes about five minutes, and the guides below walk you through it.

What it costs

Hooks cost from nothing to a few cents a batch. Reading a whole book costs from nothing to about $2.50, once per book. Set a spending limit with the AI company and you’ll never be surprised.

Which AIs work

Gemini (free or paid), Claude, ChatGPT, and OpenRouter, which gives you DeepSeek, Grok, Llama, Mistral, Qwen and hundreds more with one key.

Your book stays on your computer

It’s read and saved in your browser. When you ask the AI for something, the text passes through our server on its way to the AI you picked. It’s never stored or logged.

Your key stays on your computer

It’s saved in your browser and sent only with each request, on its way to your AI. We never store it.

Switch any time

Start with the free option and switch whenever you like. Your books and edits stay put.

Heads-up: ChatGPT Plus and Claude Pro subscriptions don’t include API access. An API key is a separate pay-as-you-go account (or Gemini’s free tier).

Pick your AI

Which one should I use?

They all follow the same hook method, and they all write good hooks. Each has its own style, so try a couple and keep the one you like.

Set-up guides

Get a key in about five minutes

Pick one. Once you have the key, open the studio, go to Hooks on the right, open AI connection at the bottom, choose your AI and paste the key.

Gemini Free tier available
  1. Go to aistudio.google.com/apikey and sign in with any Google account.
  2. Click Create API key. If it asks, accept the terms and let it create a project for you.
  3. Copy the key. It starts with AIza.
  4. In the studio: Hooks → AI connection → Use: Gemini, paste the key, and pick a Flash model from the list (Flash models are the ones on the free tier).

No card needed. The free tier has per-minute limits, so if a whole-book read says “rate limit”, wait a minute and run it again. On the free tier Google may use what you send to improve its products. For an unpublished manuscript, turn on billing in Google AI Studio (the same key then becomes a paid key, and Google stops using your content), or use another AI for the book read.

OpenRouter Best paid value
  1. Go to openrouter.ai and sign in.
  2. Open Credits and add a small amount. $5 lasts most people a long time on open models.
  3. Go to openrouter.ai/keys, click Create key, give it a name like “Bookbait”, and copy it. It starts with sk-or-.
  4. In the studio: Hooks → AI connection → Use: OpenRouter, paste the key, then choose a model. The cost per batch is shown next to every model.

Good picks to start: a DeepSeek, Kimi or GLM model for cheap, Claude Sonnet for quality. Models marked “free” exist too, but they’re heavily rate-limited and some log what you send.

Claude
  1. Go to platform.claude.com and sign up or sign in. This is Anthropic’s developer console, separate from the Claude chat app.
  2. Open Billing and buy a small amount of credit ($5 is plenty to start).
  3. Open API keys, click Create key, name it, and copy it straight away, because it’s only shown once. It starts with sk-ant-.
  4. In the studio: Hooks → AI connection → Use: Claude and paste the key. The studio uses Claude Opus 5.5.
ChatGPT (OpenAI)
  1. Go to platform.openai.com and sign in. Your ChatGPT login works, but billing is separate from a ChatGPT subscription.
  2. Open Settings → Billing and add credit.
  3. Go to platform.openai.com/api-keys, click Create new secret key, and copy it. It starts with sk-.
  4. In the studio: Hooks → AI connection → Use: ChatGPT (OpenAI), paste the key, and pick a model. Your account’s models load automatically.
FAQ

Questions people ask

Isn’t this just ChatGPT with extra steps?

No. Your key pays for the AI, but the studio tells it exactly what to do: which pages make good screenshots, how to trim them, and how to write a hook a stranger stops for. Asking an AI yourself gets you generic blurbs.

Do I pay for the studio and the AI?

Yes, separately. The studio is the plan you pick. The AI is paid straight to the AI company, usually cents, and Gemini has a free tier.

Does my ChatGPT Plus or Claude Pro subscription work?

No. Those subscriptions only cover the chat apps. The studio needs an API key, which is a separate pay-as-you-go account, or Gemini’s free tier.

Is my manuscript uploaded anywhere?

It’s saved in your browser on your computer. When you ask the AI to read the book or write hooks, the text passes through our server on its way to the AI you chose. It’s never stored or logged.

What’s in the free plan?

Every tool, the sample book, one of your own books and 5 downloads. No card, no time limit. Upgrade when you want more books or downloads.

What does lifetime include?

The studio with unlimited books and downloads, and every future update, for a one-time price. You still use your own AI key.

Can I use it without any AI?

Yes. Pick any section of your book yourself, then edit, highlight, censor and export cards, slideshows and videos by hand. The AI only does the finding and the writing.

Does it work on dark romance and open-door books?

Yes. Explicit lines are left off the cards and risky words are censored automatically. Any AI can turn down a scene now and then. If one does, try a different model.

What files can I add?

.docx, .epub, .txt and .md. PDFs lose their paragraphs, so export a .docx or .epub from Vellum, Atticus, Word or Google Docs instead.

Will the hooks be ready to post as they are?

Often, but read every one. Refresh, edit, or write your own, and save the winners.

Does it post to TikTok for me?

No. It makes the pieces: cards, hooks, slides, videos, CSVs. You download them and post on your own schedule.

What do I need on my computer?

Chrome or Safari on a Mac or PC. Videos save as .mp4 in Chrome. A video takes as long to export as it does to watch, so keep the tab open while it’s made.
