The main difference
Novelcrafter lets you bring your own AI by adding an API key, such as one from OpenRouter. API keys are billed by how much you use them, separately from any chat plan you pay for.
Scriptava connects to the Claude or ChatGPT app you already use, so the writing comes out of the plan you already pay for, with no meter running.
When Novelcrafter may suit you better
If you want to pick from many AI models through one key, or write with others on the same book, Novelcrafter offers both.
When Scriptava suits you better
- You already pay for Claude or ChatGPT and do not want a second AI bill.
- You would rather talk the book through in chat than write prompts in an editor.
- You want every chapter reviewed ten ways before you read it.
- You want to try it free for 21 days, with no card.
