In this post, I‘ll test RaptorWrite by Future Fiction Academy.

It’s a completely free AI writing tool designed to support the whole writing process. I tested RaptorWrite for AI-assisted fictional writing.

How to Use It

Enter their website and sign up. New users are encouraged to complete a short writing tutorial class by Future Fiction Academy (it’s complimentary).

This is the dashboard. Using RaptorWrite is free but to access AI, an API key from Open Router is required, which will be charged with a pay-as-you-go principle.

So, Nakki the Dogs adventures continue. If you are feeling stuck in your writing, insert your text and ask the LLM to continue your story. This is what it generated for me.

Define your prompts in the window below to create content. Be specific, more detailed the prompt, the better the outcome.

Pros

  • Free and easy to use
  • Simple interface

Cons

  • Need to understand prompt engineering to use
  • Not very flexible
  • Limited features

Pricing

RaptorWrite is completely free to use, though additional costs may apply if you connect it to OpenRouter using your API key.

To Take Home

RaptorWrite is an AI writing assistant, with a simple and minimalistic interface that helps you focus on writing without being overwhelmed by too many features. It’s great for general content, like blogs or posts, but it works for fiction writing too.

You can brainstorm ideas, create characters, outline plots, and even generate or expand scenes. Using the “rewrite” or “continue” options makes it easy to build stories.

You connect an OpenRouter API key to access more AI models, but that may come with extra costs.

Best suitable for beginner writers who are interested in incorporating AI into their writing process.
