The writer's challenge

Writing a book is a solitary journey. But you are no longer alone.

We all carry stories within us, but taking the first step is often paralyzing. Even if the desire is there, facing the screen, doubt creeps in. LocalProse was built to take the anxiety out of writing and (re)ignite your joy of creating.

Overcome writer's block

That moment when the cursor blinks into the void shouldn't terrify you anymore. If inspiration leaves you mid-chapter, LocalProse's built-in assistant suggests possible continuations, reignites the plot and unlocks your creativity in a single click.

Tame the chaos of your ideas

You don't build a complex world on a simple blank document. LocalProse provides a true workshop where your characters, locations and notes live alongside your text so you never lose the thread.

Your sanctuary

The right to write bad drafts, in complete privacy.

First drafts are always messy, clumsy and deeply personal. That's the very nature of creation. For you to write freely without censoring yourself, your workspace must be robust.

Unlike most current software, LocalProse never sends your texts to the cloud to be analyzed. The artificial intelligence that helps you brainstorm, corrects your work and gives you advice is physically installed on your computer.

No one reads your drafts. No one judges your mistakes. You can explore dozens of ideas, cross out and start over, all with unlimited use, without any subscription, without even needing an Internet connection and in the absolute silence of your machine.

For seasoned authors

Looking to leave the cloud or upgrade your tools?

Unlike cloud-based alternatives like Sudowrite (which force you into monthly subscriptions and credit limits) or legacy platforms with a steep learning curve like Scrivener, LocalProse combines the power of a modern AI assistant with the security of local storage.

Your drafts never leave your hard drive, AI usage is unlimited and syncing with the companion mobile app is done over your own Wi-Fi network, never passing through an external server. If you already have a manuscript in progress, LocalProse's smart import tool lets you recover your Word file (.docx) in a single click to pick up right where you left off.

Artificial Intelligence at home

What machine do you need to run local AI?

LocalProse adapts to your machine. The software detects your computer's power on first launch and automatically adjusts the AI's "brain" to guarantee a smooth experience.

Component Minimum (Auto Ultra-Eco Mode) Recommended (Ultra-Creative Mode)
Processor (CPU) Intel Core i3/i5 or equivalent Apple Silicon (M1+) or Intel i7/Ryzen 7
Memory (RAM) 4 GB - 6 GB 16 GB or more
Graphics (GPU) Integrated graphics NVIDIA RTX (8GB+ VRAM) or Mac
Disk Space SSD with at least 8 GB of free space (including local models installed upon launch). Up to roughly 12 GB depending on your AI engine configuration choices.
Mobile App (Android/iOS) Smartphone running Android >= 8.0 or iOS >= 15.0. Requires a Wi-Fi connection for PC/Mac synchronization.
⚡️
Mac owners (M1 or newer)

LocalProse leverages the unified architecture of your Apple Silicon chip. The AI is fast and optimized to preserve battery life.

Not sure about your hardware? Don't take any risks: start the 7-day free trial whenever you want directly from the app (it was built for this) to ensure the AI runs smoothly before investing in the Lifetime license.

Frequently Asked Questions

Do I need a very powerful computer or graphics card?

LocalProse features a smart hardware detection system. On first launch, the software analyzes your machine's memory (RAM) and automatically activates the AI engine parameters best suited to your setup. Whether you have a standard office laptop (4 to 8 GB of RAM) or a more powerful machine (Mac M1-M5 or Gaming PC), you'll enjoy the best possible AI assistance without ever slowing down your computer.

Is there a 100% free version?

Yes. If you decide not to acquire the Pro Lifetime license after the trial, LocalProse remains an excellent structured text editor with Focus mode, project management, and World-Building (character profiles, locations, mapping), but without the generative AI features.

Can I test the AI before paying?

Absolutely. We offer a 7-day free trial offering full access to all AI features (correction, rewriting, inspiration, universe management, character interviews, voice dictation, thesaurus, analysis). It's the best way to verify that your computer is powerful enough to run local intelligence before investing in the Pro Lifetime license.

Do my texts train the AI?

No! That is the very reason LocalProse exists. Every action related to the creation of your projects happens locally at your place, for total confidentiality. Nothing you write in LocalProse ever leaves your machine.

Is the software 100% offline?

Everything you type or dictate in LocalProse, on PC or mobile, never leaves your devices. Mobile/PC synchronization is done over local Wi-Fi (LAN) via your home Internet router, without ever passing through a cloud server. An Internet connection is only required to activate your trial period and your Pro Lifetime license, then occasionally to download AI "brains" during first installation and updates. The rest of the time, you can fully use the software without a connection.

What is the difference between LocalProse and Sudowrite?

Sudowrite is an online writing platform where your texts are stored on remote servers (cloud) with a monthly subscription and credit quotas. LocalProse works entirely on your machine: the AI runs locally, your data never leaves your hard drive, and AI usage is unlimited. LocalProse offers a Pro Lifetime license with a one-time payment compared to expensive monthly subscriptions.

Is LocalProse a good alternative to Scrivener?

Yes. LocalProse includes Scrivener's structuring features (chapters, character sheets, world-building, relationship mapping) and adds unlimited local AI and an offline Dictation mode. Like Scrivener, LocalProse offers a Pro Lifetime license as a one-time payment, but automatically adapts to your hardware and works on Windows, macOS, Linux, Android and iOS. All updates are included for life at no extra cost.

Which writing software uses local AI without a cloud subscription?

LocalProse is one of the few writing software tools to integrate a local AI that runs on your own machine, without depending on cloud services like ChatGPT or Claude. This guarantees total manuscript privacy and unlimited use without credit quotas.

Is there a free novel writing software?

Yes. LocalProse offers a completely free version that includes the full editor with unlimited projects and chapters, Focus mode, idea box, universe management (characters, locations, items), and Word, PDF, and TXT export. No time limits, you can write a novel from A to Z in the tool without paying a cent.

Where can I find help or chat with other authors?

I designed LocalProse for authors who want to leverage the best of AI without sacrificing the confidentiality of their texts or their creative independence.

I know how frustrating it is to have your momentum broken by a credit system, or to wonder where your texts really go when using online tools.

LocalProse brings together these two freedoms — a private workshop running locally on your own machine and unlimited usage without artificial quotas — so that AI becomes what it should be: a tool at the service of writing, not another constraint. — Alexandre Poulet
