I Tested 25+ AI Writing Tools, and This One Writes Better Than Most Humans (With Results)

#ai #productivity #writing #tutorial

You know, I have been writing online for over 5 years now.

First, I focused on Medium and made my first $100K, and now I’m focusing on my AI newsletter on Substack.

Over the last 2 years, I’ve tried a number of AI writing tools to generate content in my writing style and for different use cases.

Honestly, if a writing tool can create informative content in the exact style I want, it can make me much more productive and genuinely help in my work.

I’ve also noticed that many people are interested in the best AI writing tools to generate content in various styles for their businesses.

But to be honest, even today, if you try most of the AI writing tools, they will generate generic content or use OpenAI’s API under the hood and claim they are the #1 AI writing tool.

And so, I’m writing this post after testing 25+ AI writing tools to suggest to you some of the best options.

Note: This post contains a few affiliate links. If you choose to become a paid member through them, I may earn a small commission, at no extra cost to you.

Most importantly, I only recommend products I’ve personally used and trust.

I never promote any product just to make money or spam people. My sole intention is to provide value, and if you find it helpful, it’s entirely your choice to proceed with it.

With that said, let’s get started.

The Problem With Most AI Writing Tools

If you Google “best free AI writing tools”, you would find tons of options available.

But after testing 25+ of them myself, I can confidently say most of them are simply useless. In short, most of these AI writing tools are just using the OpenAI API to generate content.

Instead, you can simply use ChatGPT with a detailed prompt and generate content the way you want.

Also, if they generate content that can be easily detectable by AI, it makes no sense to use it since it will just make your work worse.

Here’s what you actually need:

An AI writer tool that actually uses advanced AI models trained on multiple writing styles and generates content in the exact tone or format a user specifies.
Can accurately interpret complex, multi-layered prompts and can generate differently for casual readers, professionals, or brand-specific personas based on the user’s intent.
Should naturally mimic different tones or writer voices and perform equally well across specialized domains like SEO, storytelling, copywriting, or technical documentation.
Can maintain deep context across long-form content without drifting or repeating, even in 1000+ word outputs, and produce factually grounded writing that references real data or credible examples when prompted.
Understands structure, generates clean and well-formatted sections with logical transitions, subheadings, and CTAs without needing manual fixing.
Rewrites existing drafts in a way that improves clarity, emotion, and engagement, and can generate unique ideas without hallucinating or losing factual integrity.
And obviously, writes like a human and not the same generic content an LLM model generates.

So, while researching the best free AI writing tools, I focused on the above parameters, and based on that, I found the 7 best AI writing tools you can choose from.

With that said, let’s start with the recommendations.

1. Sudowrite

If you search on Google for the best AI writing tools, chances are Sudowrite will appear right at the top.

And here’s why: unlike most AI tools built for blogs or marketing copy, Sudowrite is designed specifically for fiction writers. They even created their own AI model called “Muse”, trained only on fictional storytelling.

But what makes Muse different from other LLMs?

To prove my point, I used the same writing prompt on both ChatGPT and Sudowrite, and the difference was clear.

As you can see, both produced good stories, but Sudowrite’s output felt more emotional, vivid, and naturally written. It actually reads like a real fictional story rather than an AI-generated one.

And here are some of the best features of Muse that make it stand out:

The best part? You can further:

Adjust the style, tone, or pacing in seconds.
Expand or shorten any part of your story instantly.
Rewrite specific sentences or paragraphs while keeping the creative tone intact.
Brainstorm character ideas, plots, or twists with impressive accuracy.
And more.

Well, that’s the main reason I decided to try Sudowrite myself, and thanks to its mind-blowing features and its own model called Muse, I've placed this one in the #1 position.

To get started, you simply need to visit their website and click on the button “Try Sudowrite for free” to create an account.

Then you can start a new project and use most of the features to generate fictional content the way you want.

As you can see, it has all the features one needs, from brainstorming ideas to writing in continuation, rewriting a specific sentence or paragraph, or describing a word or phrase in different senses, and more.

What I love most is their “Story Bible” feature, which makes writing a novel unbelievably simple. In just 7 clicks, you can choose your genre, select a writing style, craft a synopsis, do a brain dump, add characters, and much more to bring your perfect novel to life.

Talking about pricing, the plans start at $10 per month and go up to $44 per month, depending on the credits you choose.

2. Fiverr Writing Service

This one isn’t technically an AI writing tool, but I want this post to be as helpful and informative as possible.

That’s why I’m including options that can genuinely make a difference for readers like you.

So, here’s one worth mentioning: Fiverr Writing Services, perfect for anyone who wants high-quality content written by real experts instead of AI.

But why include it? Because let’s be honest, most AI writing tools still struggle to match the creativity, tone, and flow of a skilled human writer. In that case, Fiverr can be a strong alternative.

You might be wondering, how do you get started?

Well, it’s simple. Visit Fiverr, type “writers” in the search bar, and browse through thousands of professionals.

You can choose the right expert based on their portfolio, reviews, ratings, and writing style.

This way, you don’t need to rely on any AI writing tool or spend hours trying to perfect your own draft. You can let experienced writers handle it for you.

And why Fiverr specifically? Because it’s one of the most trusted, affordable, and beginner-friendly platforms available. They also have Pro writers who specialize in blogs, stories, copywriting, and more.

I’ve personally hired several content writers and fiction writers through Fiverr, and that’s why I can confidently recommend Fiverr Writing Services as a reliable choice.

3. ChatGPT (or Claude)

Let’s be honest, almost everyone has heard of ChatGPT and Claude, and most AI writing tools actually use these models behind the scenes.

And the best part? Over time, both ChatGPT and Claude have become incredibly powerful across almost every category, including content creation.

So naturally, I had to include them here.

To generate content in your preferred style, simply visit ChatGPT (or Claude) and create a free account.

After that, all you need to do is write a clear and detailed prompt describing exactly what you want to generate, and you’re ready to go.

Here’s a prompt I use most often:

You are an expert writing assistant helping me write high-quality, factually correct, and original content in my personal writing style.

My writing style: Conversational, simple English, practical, and to-the-point. I like short paragraphs, natural flow, and relatable examples. My tone is confident but not robotic. I write as if I’m talking to a smart friend in informal english.

Your goals:

• Write with a human tone, no corporate or filler language.
• Avoid vague statements like “AI is changing everything”. Instead, explain how and why.
• If you mention tools, features, or facts, ensure they are up-to-date and verified (cross-check before writing).
• Use logic, storytelling, or real-world examples when relevant.
• Prioritize accuracy and clarity over word count.
• Use active voice and smooth transitions between ideas.

Topic: [insert your topic here, e.g., “How AI is changing productivity tools” or “Using NotebookLM to learn faster”]

Format: Write it like a blog post (not an essay), with a short hook in the intro, a clear flow of ideas, and a punchy closing line.

I tested it on a simple topic related to NotebookLM, and here’s what it generated:

Sure, it might feel a bit tedious at first, but that’s what makes it fun.

You can experiment by adjusting your prompt, defining the tone, and even asking ChatGPT or Claude to mimic a specific writing style.

And the best part? Both ChatGPT and Claude offer free usage limits, which makes them a perfect choice if you want to boost productivity and create better content without spending a dollar.

4. Rytr

Now, here’s another popular AI writing tool, used by over 8 million writers and boasting a 4.9 out of 5 satisfaction rate.

And here, you can generate email responses, blog posts, creative writing, social media ads, and everything in between.

I’m talking about Rytr, which focuses specifically on generating short-form content.

To get started, simply visit their website and click the “Get Rytr It’s Free” button to create your account.

And then I tried generating an email in two variants by adding a few key points, and here’s what it generated:

The best part? I can change the language, adjust the tone, and even modify specific sentences exactly the way I want, as you can see below.

As for pricing, you can start for free and generate up to 10k characters.

If you need more, you can choose the “Unlimited” or “Premium” plans to generate more content and access additional features.

5. Jasper AI

I’ve heard a lot about this one on YouTube Shorts and Instagram Reels, and it’s quite popular.

The best part about Jasper AI is that it’s specifically built to help businesses and individuals streamline their marketing process. It enhances brand experience, speeds up content creation, and helps automate marketing workflows to save both time and effort.

Most of you may already know about it, but the main drawback is that there’s no free plan, and it’s a bit expensive compared to other tools.

To get started, visit the Jasper AI website and click the “Start Free Trial” button to create your account.

Next, you’ll need to select either the “Pro” or “Business” plan and add your card details, even for the free 7-day trial.

After that, you’ll be redirected to the dashboard, which offers a variety of categories to choose from.

Here, you can explore different categories like content marketing, performance marketing, or try out features and popular apps depending on what you want to generate.

Select "Facebook Post" for example.

And from there, the process is mostly the same as what we discussed in the previous section.

6. Writesonic

Now, this is another popular AI writing tool, and they mainly focus on boosting your brand’s visibility in AI search engines like ChatGPT, Perplexity, Claude, and so on.

I’m talking about Writesonic, and it even provides you with a tracking system, SEO strategies, a content engine to generate content, and more.

To get started, simply visit their website and click on the button “Start Free Trial”.

Then it lets you generate content in a very step-by-step manner, as you can see above.

I’ve tried the complete process myself, and to be honest, it generates way better content than I ever thought.

As for the pricing, you can start a free trial with any plan and try out the above process to see the results.

And further, you can buy a paid plan if you want to.

7. Copy AI

Finally, the last tool I want to talk about helps you create content, generate pipelines, execute campaigns, close deals, and more.

I’m talking about Copy AI.

To get started, visit their website and click the “Login” button to create your account.

Once you’re in, you can choose a plan and start creating content, building advanced workflows to automate your content creation process, or even developing custom AI specific to your brand voice.

Regarding pricing, Copy AI offers two main options: Chat and Agents, as you can see below.

So if you just want to generate content and chat with AI models, the Chat plan is sufficient. But if you want to train content and build automation, the Agents plan is the way to go.

Let’s Wrap Up

So, after testing 25+ AI writing tools, here’s the takeaway: most tools are either too generic or just repackaging the same OpenAI models.

But the few I’ve shared here actually deliver results if you use them right.

First, I talked about Sudowrite because it has its own powerful AI model. One of its limitations, though, is that it’s mainly built for fictional stories. Interestingly, some might even see that focus as an advantage.

Next, I included Fiverr Writing Services because, in my opinion, the best way to create truly high-quality content is still by hiring a skilled human writer. Fiverr is a great option for that, and I can vouch for it since I’ve personally used it for years.

The rest of the list follows the same logic, focusing on tools that actually work in real situations.

Here's a quick cheat sheet for you:

• For fiction and creative writing — Sudowrite.
• For hiring a human (when you want nuance that AI still misses) — Fiverr.
• For flexible, do-it-yourself prompts — ChatGPT / Claude (use a tight prompt).
• Short-form, quick-turn copy — Rytr.
• Enterprise-level features and templates — Jasper AI.
• SEO and brand-focused workflows — Writesonic.
• Campaigns, pipelines, and automations — Copy AI.

What really matters is how you write your prompt and how honestly you edit the result.

Sure, AI can help you write faster, but you’re still the one in charge, so you need to guide the tone, check facts, and smooth out the flow.

For instance, if it sounds robotic, just rewrite the first few lines and give it back to the tool to improve.

If you want one simple starting point: use ChatGPT (or Claude) with the detailed prompt I shared, then try Sudowrite or Rytr for creative ideas.

This mix helped me save time and still keep my writing natural and human.

Hope you like it.

That’s it — thanks.
