Raptor Write is a free AI writing tool built for fiction authors by Future Fiction Academy. The software costs nothing. The AI does, because you supply your own API key and pay whichever provider you point it at, per token.
Two things every current review gets wrong. It now has cloud storage, so the widely repeated claim that everything lives in your browser is out of date. And it supports nine providers, not six.
Who Makes It
Raptor Write comes from Future Fiction Academy, an education platform founded by Elizabeth Anne West and Steph Ponas that teaches authors how to write with AI.
That origin explains the whole product. It is a teaching tool as much as a writing tool, which is why it is free, why the prompts are all editable and exportable, and why the model list includes a curated FFA Top 10 rather than a single default. The company sells courses. The software is how you practice what the courses teach.
You log in through an FFA Teachable account, which is worth knowing because your access to a writing tool runs through a course platform login rather than a standalone account.
Nine Providers, and the Key You Bring
The live app lists OpenRouter, OpenAI, Anthropic, Google, MistralAI, DeepSeek, Perplexity, XAI, and Cohere. Directory listings still say six, which tells you how quickly this has moved.
Every one of them shows the same message until you configure it: no API key entered. Nothing works out of the box. You go and get a key first.
Per-provider controls are more granular than most writing tools bother with. Temperature, an output limit running from 512 tokens up to 131,072, and reasoning effort settings. Anthropic models get a thinking budget field; OpenAI models get a verbosity setting. That is a genuinely useful level of control if you understand what those knobs do and completely opaque if you do not.
Model groupings include FFA Top 10, Free Models, All Models, and a category the platform labels Spicy, which is a curated set for explicit content. Romance and erotica are among the largest self-published fiction categories, so that is audience-serving rather than unusual.
If you are new to running your own keys across several providers, our guide to AI model aggregators and gateways covers what changes when you route this way instead of paying a platform subscription.
What “Free” Actually Costs
This is the part nobody quantifies, and it matters more here than in most bring-your-own-key tools.
Raptor Write has an autocontinue feature with settings for maximum continues and a duration in seconds. Combined with a 131,072-token output ceiling, you can leave it generating for a long stretch without touching anything.
That is the feature people came for, and it is also the one that empties an API balance. Every continuation resends context and generates fresh output. Drafting a novel this way on a frontier model is not a free activity, and the difference between a cheap model and an expensive one across an 80,000-word manuscript is substantial.
The honest framing is that Raptor Write removes the subscription, not the cost. Whether that saves you money depends entirely on model choice and how heavily you lean on autocontinue. Set a hard spending cap with your provider before you start, because the tool will not stop you.
Cloud Storage Arrived
Older coverage describes Raptor Write as storing everything in browser local storage and treats that as a privacy feature. It was accurate, and it is no longer the full picture.
The app now prompts users to convert projects to FFA Nexus, its cloud storage layer, and describes doing so as moving to the latest version. There is proper sync conflict handling behind it, with options to force overwrite, save to cloud only, or discard local changes and reload the most recent version.
That solves a real problem. Browser storage means clearing your cache can take your manuscript with it, which is a serious risk for anyone drafting a novel. It also means your work now sits on someone else’s infrastructure, which is the trade-off you are accepting.
Either way, export regularly. The app writes out Markdown, plain text, and Word, and there is a JSON backup and restore path. Use them.
What’s Actually in the App
More than the reviews suggest, and the design clearly comes from people who write.
The prompt system is the core. Prompts are fully editable, support variables for surrounding text, selected text, selected documents, user input, and the last response, and can be saved as named sets, exported, imported, and shared. Hotkeys run prompts three through twelve directly, with a backslash to continue or revise depending on whether you have text selected.
Documents are organized into folders with drag-and-drop ordering that controls how they feed into the prompt context. There is a built-in Pomodoro timer with its own settings, which tells you the target user is someone doing timed drafting sprints rather than a marketer knocking out product descriptions.
Accessibility options include a large high-contrast action menu. Notion integration is listed as coming soon, and the documentation itself lives on a Notion page.
It’s Still Version 0.69.
The app identifies itself as Raptor Write Plus V0.69 and carries a separate button to export to something called RW 1.0.
Two years or so after launch, the tool you use daily is still numbered below 1.0, and a successor version exists that you migrate to rather than update into. There is also a notice recommending a hard browser refresh whenever a new version ships, which tells you something about how updates reach you.
None of that makes it unusable. Plenty of people are writing books in it. But if you are choosing where a manuscript lives for the next year, a perpetually pre-1.0 tool with a parallel 1.0 branch is a reason to keep your exports current.
Be Careful Which Reviews You Read
The search results for this tool are unusually contaminated, and it is worth naming.
One prominent review claims six months of intensive testing by a content marketing professional with Fortune 500 experience who has evaluated fifty-plus AI writing tools and reports that Raptor Write generates a thousand words in two to three minutes. It frames a fiction-writing tool built by a fiction academy as a content marketing product, which suggests the writer never opened it.
Another describes a paid version offering unlimited access, alongside a roadmap featuring voice dictation and collaborative writing. No paid tier appears anywhere in the live app or in any other source, and none of those roadmap features exist.
Fabricated experience claims are a broader problem in AI tool coverage, and they are easy to spot once you know the shape: specific-sounding testing durations, invented credentials, and feature claims that contradict the actual product. Check any review against the live app before you trust its conclusions.
Who It’s For
Strong fit: fiction authors who want to control the model, the temperature, and the prompt, and who are willing to manage API keys to get that control. If you have ever been frustrated by a writing tool deciding how your prose should sound, this is the opposite of that.
Also good: anyone learning AI prompting seriously. The exportable prompt sets and per-provider controls make it a teaching environment, which is exactly what it was built to be.
Poor fit: writers who want to open a tool and start typing. Between the Teachable login, the API key setup, and nine providers to choose between, there is real friction before you write a word. For a simpler path into book-length AI work, our roundup of AI ebook generators covers tools that handle the model choice for you.
Wrong tool entirely if you are producing marketing copy or blog content, whatever the reviews claim. Look at dedicated AI writing tools for that.
One thing worth settling before you publish anything drafted this way: platform permission and copyright are separate questions, and we covered that distinction in detail when looking at AI content ownership and copyright. The same reasoning applies to prose.
Frequently Asked Questions
Is Raptor Write really free?
The software is free with no subscription. You pay your chosen AI provider directly for token usage, which for novel-length drafting is a real ongoing cost.
Do I need an OpenRouter account?
No. OpenRouter was the original route and remains one option, but the app now supports eight other providers directly, so you can bring a key from whichever you already use.
Where is my work stored?
Both locally and, if you convert your projects, in FFA Nexus cloud storage. Older reviews describing it as browser-only are out of date. Export backups either way.
The Practical Call
Raptor Write is a legitimate tool with a clear audience, and the free-software model is honest as far as it goes. What it removes is the subscription, not the bill.
Before committing a manuscript to it, do two things. Set a spending cap with your API provider, because autocontinue plus a 131,072-token output ceiling can run up a number you did not plan for. And export a backup after every session, because a pre-1.0 tool with a parallel 1.0 branch and a hard-refresh update model is not where you want your only copy of a novel to live. Do both, and the control it gives you over the actual writing is hard to get anywhere else at this price.
