The Top AI Writing Tools for 2025: Tested & Reviewed

The Top AI Writing Tools for 2025: Tested & Reviewed

 

If you’re a marketer, content creator or business owner, you’re likely already using AI writing tools in some form.

They’ve found their way into my workflow as well.

And why not? These tools can draft blog posts in seconds, generate high-converting ad copy on the fly, transform rough ideas into polished presentations and even create compelling videos from simple text prompts.

In fact, a survey by Influencer Marketing Hub showed that 35.1% of marketers used AI for content production in 2024.

While that’s nearly a 10% year-over-year decrease from 2023, it doesn’t mean AI adoption is slowing down—it’s actually evolving.

Tech giants like Amazon, Microsoft, Alphabet and Meta are collectively planning to invest over $320 billion in AI infrastructure in 2025.

And according to Ross Fledderjohn, the CEO & Co-Founder at SiteRight & Stammer.ai, we’re only scratching the surface of what’s possible:

“Right now is the worst these AI apps will ever be! I review hundreds of AI apps every month and they are improving at an incredibly rapid pace with updates being pushed daily.

People always ask me how to get started without feeling overwhelmed and I simply say you have to just sit down and take an hour to try them out.

You’ll be way ahead of the competition, knowing exactly which ones work best for your business and able to pump out content—organic and paid—for way less than traditional costs.”

The bottom line? No matter how powerful AI is today, it’s the least advanced it will ever be. And that means the way we create content is only going to get smarter and faster.

I’ve even noticed that marketers are becoming more strategic by balancing automation with authenticity to ensure content remains human-first.

With that in mind, I’ve rounded up 12 of the best AI writing tools to show you which ones actually help humans create better, more engaging content—not just robotic text or generic designs.

Let’s dive in.

Best AI Writing Tools for Drafts

AI writing tools can speed up content creation, whether it’s blog posts, ad copy, or long-form articles. But not all AI writers are equal. Some are better for creative storytelling, while others focus on structured, SEO-friendly content.

I tested Claude and ChatGPT to see how they perform across different writing tasks.

Claude

Overall Rating: Claude is a top-tier AI writing assistant known for its smooth, natural writing style. It’s great for marketers, bloggers and businesses that need high-quality content.

  • Writing Quality & Readability: (4.5/5) — Produces clear, well-structured content that reads naturally.
  • Creativity & Adaptability: (4.5/5) — Handles storytelling and creative writing well but can sometimes repeat ideas.
  • Content Accuracy & Research Capabilities: (4/5) — Generates insightful responses, but since it doesn’t browse the web, some details might be outdated.
  • Ease of Use & Customization: (4.5/5) — Simple interface with adjustable tone and style.

To ensure fairness in this comparison, I entered the same prompt in both Claude and ChatGPT:

“Write a 250-word educational article on ‘The Surprising Benefits of Taking Cold Showers Daily.’ Cover at least 3 key benefits. Keep the tone engaging and informative and end with practical tips for beginners.”

And selected their most advanced models: 3.5 Sonnet for Claude and 4o for ChatGPT.

Here’s what Claude generated:

best AI writing tools - Claude

The writing is great, and to be fair, “human” too. It covers top benefits, follows the tone I asked it to write in and has a tip for beginners at the end too. It did everything that I asked it to.

One caveat with Claude (and other AI writing tools) is that it’ll make things up and present them as facts.

For example, Claude wrote, “Researchers at the Netherlands’ Radboud University found that people who ended their showers with a 30-second cold blast took 29% fewer sick days than those who didn’t.”

And when I asked it to share the source with me, it simply backtracked by saying it may have stated the percentage incorrectly:

Overall, I like the writing style, accuracy and ease of use of Claude. To me, it’s definitely up there with the best free AI writing tools.

ChatGPT

Overall Rating: Brilliant. It’s great for all sorts of writing and reasoning tasks, from marketing copy to creative storytelling.

  • Writing Quality & Readability: (4/5) — Produces well-structured content that flows naturally but will sometimes use those overly used “AI words.”
  • Creativity & Adaptability: (4.5/5) — Handles different writing styles well and adjusts tone effectively.
  • Content Accuracy & Research: (4/5) — Delivers solid, fact-based responses with access to up-to-date information (on paid versions).
  • Ease of Use & Customization: (4.5/5) — Intuitive interface with custom GPTs and memory.

I entered the same prompt as I did in Claude, and here’s what ChatGPT came up with:

Right off the bat, I like ChatGPT’s presentation more than Claude’s. It does a fantastic job by breaking down benefits into subheadings and quickly rounds up tips at the end. Content-wise, there’s not much to pick between the two.

One thing (and that’s a major plus) with ChatGPT is that you can use the Search feature to find up-to-date information on your topics. I asked it to “Let’s add real-life stats to improve this piece.” and here’s how it improved the content:

best AI writing tools - ChatGPT

It added actual stats and gave me sources too. But a word of caution: don’t trust it blindly.

Here’s what B2B content strategist Mahnoor Sheikh says about using ChatGPT for research:

“I use ChatGPT every day as a writer, but never trust its sources. It will confidently cite statistics or research papers that either don’t exist or are misattributed.

Still, it’s incredibly useful for getting past writer’s block and exploring different angles. You just need to verify everything it tells you.”

Best AI Writing Tools for Blog Post Generation

I know what you’re thinking: doesn’t ChatGPT and Claude do the exact same thing?

Well, yes, sort of. But there are specialized blog post generators out there that go beyond just generating text.

Frase and Writesonic are built specifically for SEO-driven, structured content. They analyze top-ranking pages, suggest relevant keywords, and optimize your writing for better search visibility.

I tested both to see how they compare.

Frase

Overall Rating: Frase is a powerful AI blog post generator that combines SEO research with AI writing.

  • Writing Quality & Readability: (4.5/5) — Generates structured, clear and SEO-friendly content.
  • SEO & Research Capabilities: (5/5) — Analyzes top-ranking articles, suggests keyword-rich headings and provides real-time SEO optimization.
  • Customization & Adaptability: (4.5/5) — Offers flexible AI-assisted writing and allows users to generate full drafts or work manually with SEO insights.
  • Ease of Use & Workflow: (4.5/5) — Simple, intuitive UI with strong SEO integrations.

I gave both Frase and Writesonic the same prompts to test their capabilities:

“Write a 1,000-word blog post on the benefits of hybrid work, optimized for SEO.”

The keyword to focus on was “benefits of hybrid work”.

This is what Frase generated:

best AI writing tools - Frase

I like that it searched the top-ranking pages before generating the post, instead of just writing blindly.

The introduction was engaging but fairly generic (will definitely need to tweak that). However, the body of the post was well-organized, with keyword placement that felt natural rather than forced.

Frase can include stats and citations in the blog posts, but be sure to verify the sources.

I like the real-time SEO scoring of Frase. It allowed me to adjust the content’s readability, heading structure and keyword density for better search visibility.

The downside, however, with all AI-generated content (not just Frase) is that the content is repurposed. Sure, it’s good for SEO, but lacks any individuality and a strong unique voice.

That said, Frase is an excellent tool for content marketers who prioritize ranking potential.

Writesonic

Overall Rating: Writesonic is a high-speed AI blog post generator designed for marketers, bloggers, and businesses that need SEO-friendly content at scale.

  • Writing Quality & Readability: (4/5) — Produces clear and well-structured content, though it can sometimes feel formulaic without human refinement.
  • SEO & Research Capabilities: (5/5) — Includes built-in keyword optimization and integrates with Surfer SEO for better ranking potential.
  • Customization & Adaptability: (4/5) — Allows tone and style adjustments.
  • Ease of Use & Workflow: (4.5/5) — User-friendly interface with pre-built templates, one-click AI article generation and automation tools (like bulk content creation) for faster content creation.

I was blown away by the depth of response by Writesonic. It showed me the work it was doing at the back end and then generated a full-fledge research analysis report on the keyword “hybrid work benefits”.

best AI writing tools - Writesonic

After it completed all of that, it then went on to generate the blog post:

best AI writing tools - Writesonic

Overall, I like the results. Sure, a few words and sentence structures sound robotic, but I love that it did all the research on its end to finalize the subheadings that should go in the article, stats and even the angles blog post should focus on.

Pricing

  • Free
  • Individual: $16/mo (billed annually)
  • Standard: $79/mo (billed annually)

Jasper

Overall Rating: Jasper AI is a well-known AI writing assistant designed for marketers and businesses that need high-quality copy at scale. It specializes in generating copy with an intuitive interface and deep customization options.

  • Writing Quality & Readability: (4/5) — Produces well-structured  content with strong contextual understanding, though occasional AI-generated quirks may require minor editing.
  • Customization & Flexibility: (4.5/5) —Offers multiple templates, tone adjustments, and even a brand voice feature to maintain consistency across content.
  • Customization & Adaptability: (4/5) — Allows tone and style adjustments.
  • Ease of Use & Workflow: (4.5/5) — Writes fast, and the workflow is user-friendly, making content creation much more efficient.
  • SEO & Marketing Features: (4/5) — Integrated SEO tools (via Surfer SEO) help to optimize content, but require an additional subscription.

Once inside Jasper’s dashboard, you can start a new project using one of its pre-built templates or the Brand Voice feature to align AI-generated content with your style.

For this test, I used the Blog Post Workflow:

  1. Entered a prompt with a topic, key points, and desired tone.
  2. Selected a length and let Jasper generate a draft.
  3. Used the Edit with AI feature to refine sections and improve flow.

After it completed all of that, it then went on to generate the blog post:

Jasper quickly created a structured, readable blog post with logical headings, relevant details, and a tone that aligned with the prompt. The AI-generated copy was coherent and engaging, though I had to tweak phrasing and transitions in some areas.

Best AI Writing Tools for Presentations & Documents

Creating presentations and documents from scratch isn’t just about design—it’s a content creation process that takes time and effort.

You need to structure your ideas, refine your messaging, and craft compelling visuals to make an impact.

But with AI-powered content generators, you can streamline the process, letting your assistant handle the heavy lifting while you focus on fine-tuning the final result.

I tested multiple AI-driven tools designed for both content creation, built-in AI writing tools and presentation design, but two stood out: Visme and Gamma. Here’s how they performed.

Visme

Overall rating: Visme AI produces remarkable presentations—all complete with colors, images, presentation copy, icons and intelligent layouts. It’s the best in class when it comes to AI-generated presentations.

  • Design Quality & Visual Appeal: (5/5) — AI-generated slides are polished and professional with a strong focus on branding and customization.
  • Content Structure & Relevance: (4.5/5) — AI organizes slides logically and effectively, though some manual tweaks may be needed for flow.
  • Customization & Flexibility: (5/5) — Visme gives you total control over how your presentation looks and feels. It allows deep customization to match brand guidelines, add animations, interactive elements like buttons, flipbook and hover effects and more.
  • Ease of Use & Speed: (5/5) — The interface is super simple and straightforward. And it took less than 5 minutes to create, edit and share the AI-generated presentation.

To get started, all you have to do is go to your Visme dashboard and find and click on Create with AI. It’s pretty hard to miss. And on the “chat” interface that pops up, write in detail the type of presentation or document you want the AI assistant to generate.

To make sure this comparison is completely unbiased, I shared the same prompt with both design tools:

“Create a presentation on ‘The Future of Remote Work: Trends, Benefits, and Challenges.’ The presentation should include a title slide, an introduction, three key trend slides, a benefits slide, a challenges slide, and a conclusion. Use a professional and engaging tone with a clean and visually appealing design.”

The chatbot then asks you to choose a style for the presentation. This may seem like a simple addition, but I love that it shows you different styles so you’re bound to find something that matches your aesthetic.

Once you make your selection, wait a minute or two and let AI do its work.

Here are the results:

best AI content generators - Visme's AI design generator

I know this isn’t perfect by any stretch of the imagination, but wow, these look really good!

I’ll need to make some color changes, text and image alignments and tweak the copy, but considering that this took me less than 2 minutes, we’re in crazy good territory here.

Now that I have my AI-generated design, I’ll go in and add my brand colors. Instead of manually uploading my colors and logos to the platform, I’ll turn to Visme’s Brand Wizard for this—just enter your website URL and the AI wizard will pull all your brand assets and store them in your Brand Kit for one-click addition to your projects.

Next, I’ll adjust the presentation copy. If I have something already written down, I’ll just copy-paste it to the project but if I’m unsure of what to write I’ll ask Visme’s AI writer to generate text for me. It works the same way as ChatGPT does: the better the prompt, the better the output.

Next, adjust the imagery of the presentation. Visme has a stock photo and video library that you can choose from. It also has a vector icon library where you’ll find animated visuals to spruce up your projects.

While on the subject of AI, you can also use the platform’s other AI tools, like:

For example, here’s Visme’s AI background remover tool in action:

Visme's AI background removal tool in action

And on top of all these AI features, Visme also has dynamic fields that automatically adjust content based on different audiences, a range of  interactive content creation tools and advanced collaboration tools—making it easily one of the best AI generators for presentations, documents, ebooks and more!

Pricing

  • Basic: Free
  • Starter: $12.25/mo
  • Pro: $24.75/mo
  • Enterprise: Custom pricing

Gamma

Overall Rating: Gamma AI is a great AI presentation tool that prioritizes speed and simplicity over deep customization. It quickly generates well-structured, scroll-based presentations, which makes it a great choice for users who need instant presentations with minimal design effort.

  • Design Quality & Visual Appeal: (4/5) — AI-generated slides are clean and modern, but the scroll-based format might not suit all presentation styles.
  • Content Structure & Relevance: (4.5/5) — Gamma organizes content logically and concisely.
  • Customization & Flexibility: (4/5) — Gamma offers a simple and intuitive editing experience that allows users to refine text, adjust layouts and apply basic design tweaks.
  • Ease of Use & Speed: (5/5) — It takes just a few clicks to generate a presentation, making it ideal for fast-paced workflows or users who want a simple, no-fuss experience.

Once inside your Gamma interface, click on Create New AI to get started. On the screen that pops up, you’ll have three choices to pick from:

  • Paste in text
  • Generate
  • Import file or URL

I chose the second option to keep the review consistent.

I entered the same prompt as I did while testing Visme and selected the number of slides I wanted in my presentation.

best AI content generators - Gamma

Gamma then quickly created an outline for the presentation and asked me to pick a theme of my choice, amount of text per card and image sources.

I like how Gamma lets you pick and choose from where you want your images sourced. These could be web images, illustrations or AI images. I chose AI images as my source and the pre-selected Flux Fast AI image model.

Here’s the result:

best AI content generators - Gamma AI

Again, the results are not perfect, but really good. Even though I’m tired of seeing AI images and don’t think they add “personality” to professional projects, these were generally relevant to the topic and got a pass from me. Plus, you can always go and change how you want your images sourced.

The presentation layout was terrific, but the copy leaves much to be desired. No big issues as you can always use the platform’s Edit with AI feature to improve writing, fix grammar, translate etc.

Probably my biggest issue was the similarity of theme options. Sure, the presentation colors and font styles are different for each. 

GPT-4But after a while, the layout of all Gamma presentations starts to look the same. Overall, though, Gamma’s AI does some pretty fantastic stuff and you can’t really go wrong with it.
