A ghostwriter with a red pen

How it works
Three steps. The middle one takes two seconds.
- 01
Say it badly.
Dump the idea the way you'd text a friend. Half sentences, bullet points, typos. All fine.
- 02
Pick where it goes.
LinkedIn, X, a blog, a cold email, a toast. Each format knows its own rules: hooks, limits, structure.
- 03
Get it back edited.
A red pen pass cuts the clichés and fixes the rhythm. Then a check makes sure it actually fits the platform.
The red pen
Most AI writing gives itself away with the same forty phrases.
“Delve.” “In today's fast-paced world.” “It's not just X, it's Y.” A flat rhythm where every sentence is the same length. We catch them, cut them and show you the score before and after.
In today's fast-paced world, hiring the right talent is more crucial than ever. Let's delve into my journey: I learned that it's not just about skills, it's about culture fit. This was a game-changer for our team.
I hired my first employee off their CV. Three months later we were both miserable. Now I spend the first fifteen minutes of every interview telling candidates what's bad about working here. Some walk out. Good.
The red pen is an editor, not an AI-detector dodge. It makes drafts read better; it doesn't promise anything about detectors.
Formats
Seventeen formats. One engine underneath.
Every format brings its own rules: the hook that has to land before “see more”, the 280 characters, the 30-character ad headline. Same engine, different playbook.

Your voice
Paste three things you wrote. It picks up the rest.
Tone, sentence length, the words you lean on, the ones you'd never use. We turn your samples into a voice profile and every draft follows it. Your samples stay in your account.
- 01Short sentences. Fragments, even.
- 02Says “honestly” too much.
- 03Never uses exclamation marks.
- 04Opens with a scene, not a thesis.
Rules, counted
It counts characters so you don't have to.
Each format is checked against the platform's limits after writing. If something runs over, it gets fixed before you see it.
Languages
Writes in eight languages.
English, Turkish, German, French, Spanish, Arabic, Russian and Azerbaijani. The interface speaks English and Turkish.

Questions
Things people ask first.
What is AI Ghostwriter?
AI Ghostwriter is an AI writing app that turns a rough idea into a draft in your voice. One engine runs 17 formats, from LinkedIn posts and cold emails to essays, book chapters and wedding toasts, and each format follows its platform's rules. A red pen pass then cuts the phrases that make AI writing easy to spot.
How is it different from a general chatbot like ChatGPT?
A chatbot will talk about anything; AI Ghostwriter only writes, and each format brings its own rulebook. It counts characters and fixes what runs over (280 for an X post, 30 for a Google Ads headline), outlines long pieces before drafting, writes in a voice built from your own samples and shows a naturalness score before and after the red pen.
What does the red pen do?
The red pen is an editing pass that runs after the draft. It looks for stock phrases, a flat sentence rhythm, piles of em dashes and sentences that all start the same way, then fixes them: Light touches only the problem sentences, Strong rewrites more freely, and Off skips the pass. You see what it crossed out and a 0-100 naturalness score before and after.
What is a voice, and how do I create one?
A voice is a style profile built from your own writing: your tone, sentence length, the words you lean on and the ones you avoid, plus a few short excerpts. Paste at least 300 characters of your writing (2-5 pieces works best) under Voices, then pick that voice in the composer. The Free plan includes 1 saved voice.
Can I try it without an account?
Yes. Type into the box on the homepage and send; visitors currently get 2 drafts a day without signing up. Trial drafts aren't saved, and a free account gives you 10 drafts a day, history and your own voice.
Do you train AI models on my writing?
No. We don't train models on your content and we don't sell your data. Your text goes through OpenRouter to the AI model provider only to generate what you asked for, and your drafts and voices stay in your account until you delete them.
Your next post is one rough sentence away.
