About Natural Write

We make tools that help people write clearly, in their own voice.

Natural Write is an AI writing assistant. It refines drafts, checks grammar, rephrases sentences, verifies citations, and analyzes text, without losing the writer’s ideas or voice. It runs on the web, on iOS, Android, and macOS, and through an API. A Chrome extension is coming soon. Natural Write is built and operated by Natural Write Inc.

Built to help you write naturally

Good writing sounds like a person, not a template. We think anyone can say what they mean clearly, in their own voice, with the right tools.

We don’t try to replace the writer. Our tools take text that already exists, a rough draft or a paragraph that doesn’t flow yet, and make it clear and natural.

Our tools

One account, one word balance, every tool:

AI Humanizer

Rewrites text so it reads naturally and keeps the meaning. Train it on your own writing.

AI Detector

Estimates how likely a text was written by AI, so you can review it before publishing.

Paraphraser

Rephrases sentences and paragraphs for clarity and variety, without changing what they actually say.

Grammar Checker

Fixes grammar, spelling, and punctuation mistakes, and suggests cleaner phrasing where it helps.

Citation Checker

Verifies references against scholarly sources: authors, titles, years, and DOI links, before you submit.

Doc Editor

Every tool in one workspace. Write, format, and polish; your document saves itself as you type.

Our journey so far

Natural Write started in 2025 with one tool: a humanizer that turned stiff, machine-sounding drafts into natural prose. More and more people were writing with AI, and most of it still needed a human touch.

The humanizer found its audience fast, so we built around it: a detector, a paraphraser, a grammar checker, a citation checker, and a Doc Editor that puts them all in one place. Then apps for iOS, Android, and macOS, a public API, and Spanish, Portuguese, and Arabic.

Today more than 2 million people have a Natural Write account. The goal hasn’t changed: help people say what they mean, in their own voice.

Our principles

Your ideas stay yours.

We’re an assistant, not an author. Our tools refine the text you give them, and you remain the author of all of it.

Privacy by default.

We don’t sell personal data. Your text is used only to do what you asked, in line with the GDPR, CCPA, and PCI DSS.

Responsible use.

Follow the rules of your school, workplace, or publication. We say plainly what Natural Write is for. Read our Responsible Use policy.

Simple and fast.

Nothing to install or configure, no learning curve. Paste your text, pick a tool, and get a result back in seconds.
