When you’re writing, you can usually tell when a sentence just doesn’t sound right. Maybe it feels too stiff, too formal, or like something an AI would write. Fixing those lines takes extra time, and it can slow down your whole flow.

That’s why tools like TwainGPT catch your attention when you’re trying to clean up your drafts and make them sound more natural. If you’ve been looking for something that helps your writing feel more like you, this guide will help.

In this article, we'll cover the 5 best free TwainGPT alternatives that you can use to humanize text and improve your writing in 2025.

What is TwainGPT?

TwainGPT is an AI writing assistant that helps rewrite text to sound more natural. It adjusts tone, removes stiffness, and makes writing feel more human. It works as a quick way to revise drafts and clean up awkward sentences.

Writers use it to improve writing and keep their style consistent. The tool focuses on rewriting instead of generating long new pieces of content.

Is TwainGPT Free?

TwainGPT offers a free plan, but it only includes 250 words. Once you run out, you have to upgrade to a paid plan.

To get more words, you have to choose one of TwainGPT's paid plans: Basic ($10/month, 8,000 words), Premium ($25/month, 30,000 words), Ultimate ($50/month, unlimited words).

While it is useful, TwainGPT's price tag can lead some users to look into other options that offer expanded free access or even free plans particularly for students.

What to Know About Humanizing Text With AI
