7 Best Long Form AI Writing Tools for Amazing Content (2025)

Ever stared at a blank page for hours, trying to create the perfect 2,000-word blog post? I’ve been there, and it’s soul-crushing. 

The good news? The rise of AI writing tools has completely changed how creators produce content.

According to recent research, 36% of marketers using AI spend less than an hour on long-form content—a task that used to eat up my entire weekend.

When I switched from hiring dodgy Fiverr writers to the use of AI, my content production tripled. 

These tools don’t just save time, they boost your SEO, kick writer’s block to the curb, and keep quality consistent even when you’re writing massive guides or just simple social media posts.

This shows very clearly the potential of AI tools to massively scale up content production. 

Ready to transform your content creation process? 

Let’s dive into the 7 best long form AI writing tools for bloggers to try that’ll change how you create SEO-friendly content at scale.

What Are the Best Long Form AI Writing Tools?

Let’s chat about the top AI writing tools that have really helped to speed up writing content for my blog.

I’ve spent countless hours testing dozens of new tools (and wasted plenty of money in the process), but these seven have genuinely transformed my content writing workflow for creating proper long-form SEO writing as well as updating your existing content.

When I first started using AI for writing, I was pretty skeptical about whether these tools could handle in-depth articles. 

Most just spat out generic fluff that needed tons of editing. 

But these specific tools? They’re in a different league altogether.

1. Claude AI

Unlike other tools that start repeating themselves after 500 words, Claude maintains context throughout entire 10,000+ word articles without breaking a sweat. 

The way it handles complex topics with nuance and depth is genuinely impressive – I’ve used it to write technical guides that make sense, something most AI assistants struggle with.

I use Claude every day as my main AI writing assistant, primarily for churning out long-form blog posts.

What stands out is how human it sounds compared to other tools on this list. There’s a creative quality to its writing that just feels like human writing that is more natural and engaging.

The interface is clean and intuitive, and the projects feature is brilliant – I’ve set up different project templates for different content types, each with custom prompts and instructions that are ready to go.

The biggest game-changer for me has been how Claude avoids that annoying repetition problem that plagues most AI writing generators. 

It transitions smoothly between topics and maintains a consistent voice throughout, even when tackling complicated subjects that require subtle understanding.

Key Benefits

• Crazy good context memory – handles 200,000 tokens (about 500 pages!) without forgetting what it was talking about
  
• Sounds human – no more robotic SEO content that screams “AI wrote this!”
  
• Projects feature – save all your prompts and docs in one place instead of copy-pasting instructions constantly
  
• Zero hallucinations – doesn’t make up random facts like many AI tools do (this used to drive me mad)
  
• Handles complex topics – can explain technical stuff without turning it into meaningless word salad
  
• Ridiculously versatile – writes in any style or tone you want, from professional to conversational.
  
• Outlines like a pro – creates detailed content ai text structures that make sense for long articles.

Pros & Cons

2. Jasper

When I first tried Jasper for long-form content, I was skeptical about whether it could maintain quality beyond a few paragraphs. 

Boy, was I wrong!

Jasper absolutely shines when creating structured long-form blog posts, with templates specifically designed for extended content that actually flows naturally from the intro to the conclusion making it simple to just sit down and start writing. 

It is honestly one of the best content writing that I have seen. 

What sets Jasper apart is its uncanny ability to maintain your brand voice consistently throughout thousands of words. 

It was the first AI tool I ever used, and I immediately fell in love with its pre-made templates and the recipes shared by the community. 

These templates saved me hours of figuring out how to structure different types of content. 

The Chrome extension that follows you around the web is brilliant too, with anyone being able to improve their writing wherever you are online instead of constantly switching tabs.

Jasper’s SEO integration with Surfer is brilliant for long-form high-quality content that ranks. I’ve noticed my Jasper-written articles climb higher in search results because they’re optimized from the start, not as an afterthought. 

The ability to work in 80+ languages also makes it invaluable for creating content for different markets.

Pros & Cons

3. ChatGPT

Like most of the world, I have been a fan of ChatGPT since it was first introduced a few years ago, using it for everything from quick outlines to massive guides. Its honestly one of the best AI tools out there still.

Over time, I’ve found a few handy ways to make it shine for long-form content.

Approaching writing blog posts and other long form writing using the step-by-step expansion approach has been a game-changer.

Instead of asking it to write an entire article at once (which produces generic, robotic output), I get ChatGPT to break topics into manageable chunks, developing summaries first before expanding them into detailed sections.

What surprised me most was the customizable tone and style. Like Claude and Jasper, giving it brand voice guidelines keeps writing consistent in tone and quality. 

I’ve had it create everything from technical SEO guides to conversational reviews with personal anecdotes.

For longer pieces, the iterative refinement approach works wonders.

I’ll get a draft, then ask for specific rewrites with instructions like “make this section more conversational.” 

The specialized “GPTs” have changed how I approach my daily writing tasks too. 

There are many different ones in the GPT library solely devoted to writing long-form content that is humanized and plagiarism-free. 

It’s up to you to test out different ones and see which you get the best results from.

• Mind-blowing outlines – Creates detailed content frameworks in seconds that would take me hours to plan manually.

Pros & Cons

4. Scalenut

I discovered Scalenut recently when I was looking for SEO-focused AI writing tools, and it’s become one of my favorites for creating long-form content that readers and search engines love. 

What caught my eye was how the whole platform is built around search performance instead of just writing random stuff.

The AI templates work great for all kinds of content formats. 

Whether you’re writing product reviews, how-to guides, or comparison articles, they’ve got templates with the right structure already built in. 

I love how they automatically add proper headings and suggest related keywords right in the template.

I haven’t had the chance to use Scalenut for any client projects yet, but I’ve tested it on my blog. 

The keyword research tool is brilliant, it looks at what’s already ranking for your topic and tells you what subtopics to include, and questions to answer. 

It even tells you how long each section should be to compete with top results.

The “Cruise Mode” feature is very handy too. 

It puts the whole content creation process on autopilot, from research to finished articles, without me having to do much at all.

Pros & Cons

5. Writesonic

I stumbled upon Writesonic when I needed to create a bunch of long-form articles but kept hitting writer’s block. 

Unlike other AI tools that spit out random paragraphs, Writesonic is an AI-powered writing tool that builds structured articles with proper flow from the intro to the conclusion.

The SEO capabilities caught me by surprise – it doesn’t just stuff keywords but analyzes what’s ranking and suggests content structure based on that data. 

For my blog, focused on AI, automation and content marketing tactics, this meant going from page 5 to page 1 for several target keywords.

Beginners find Writesonic easy to use because of its guided approach. 

My cousin just started a travel blog with zero writing experience, and the step-by-step article builder had her create comprehensive destination guides within her first week.

What impressed me most was how thorough the topic research tool is, it pulls questions from Google, Reddit, and Quora so you’re addressing what people want to know, not just what you think they care about.

Pros & Cons

6. Frase

Frase is an AI-powered writing assistant that helps users generate high-quality content efficiently.

What sets Frase apart for me is its focus on research and SERP analysis before you write a single word.

The platform analyzes top-ranking content for your keywords and shows exactly what topics they cover, helping you create more comprehensive articles and basing recommendations on what’s ranking right now.

Their semantic keyword suggestions have been particularly valuable. 

When writing about technical topics, Frase identified related terms that I wouldn’t have thought to include but that Google clearly values. 

This research-driven approach means my content addresses the full topic, not just surface-level information.

Frase is a tool that uses AI to help you understand why certain content ranks and guides you to create something better. 

For SEO-focused content creators, this data-backed approach delivers much better results than generic AI writing.

Pros & Cons

7. Writecream

I discovered Writecream when looking for a tool that could help create content in multiple languages for a client’s international blog.

What immediately caught my attention was how it supports over 75 languages for both text and audio outputs – a massive advantage for global content strategies.

The long-form editor has some unique features I haven’t seen elsewhere. The Command Mode lets you give specific instructions about tone, style, and content structure directly within the editor. This gives you much more control over long articles than most AI tools provide.

When I needed to create Spanish and English versions of a 3,000-word guide on sustainable fashion, Writecream handled both languages impressively well. The Spanish version didn’t feel like an awkward translation but read naturally with proper idioms and expressions.

What enhances the long-form content creation is how seamlessly it integrates with other tools like the paraphrasing feature and summarizer, letting you refine sections without switching platforms. The ability to instantly turn articles into podcasts with natural-sounding voices gives content extra mileage too.

Pros & Cons

What Is Long Form AI Writing?

I first got into using AI for long-form content last year when I was drowning in writing projects for my blog. 

Long-form AI writing means using artificial intelligence to create extended content pieces of 1,000+ words like comprehensive guides, detailed tutorials, or massive comparison articles.

The tech behind these tools is pretty fascinating. These AI tools are trained on billions of text examples from books, articles, and websites. 

What’s been game-changing recently is how the new models can actually “remember” what they wrote earlier in the article. 

My first experiences with AI writing back in 2022 were frustrating because the tool would contradict itself after a few paragraphs or completely forget the main point it was making!

There are a lot of preconceived notions about AI writing. Some people still think it can only generate AI content that is shallow, generic content, which just isn’t true anymore. 

I’ve found the sweet spot is using AI to handle the heavy lifting of research and creating the initial draft, then jumping in myself to add personal experiences, tweak the tone, and fact-check everything. 

This approach gives me the best of both worlds, the efficiency of AI with the personality and expertise only a human can provide.

How Can Long Form AI Writing Tools Benefit You

I measured how long it took me to create content before and after using AI tools. 

The results were amazing! What used to take me a full day (about 8 hours) now only takes about 3 hours with AI help. 

That’s a 60% time savings! 

Now I can publish three times more content without working crazy hours.

AI tools are super helpful when you don’t know what to write. Instead of staring at a blank page feeling stuck, I get the AI to create a rough draft or outline. 

It’s way easier to fix and improve something that already exists than to create everything from scratch. 

This has saved me from many frustrating moments when working on big articles.

The SEO benefits have been really impressive too. 

My AI-helped articles include important related keywords I would’ve missed on my own. 

One of my AI writing guides jumped to page 1 of Google because the AI naturally included terms that matched what people were searching for. 

Plus, my longer articles now keep the same style and tone throughout, which keeps readers interested to the end.

Buyers Guide: How I Conducted This Research

Now let me walk you through my deep dive into finding the best long-form AI writing tools. 

This wasn’t just another casual review, it was a proper investigation that took weeks of testing because choosing an AI tool that is up for the job is crucial.

Final Thoughts

Look, I’ve been there – staring at a screen, wondering if these AI writing tools are going to save me time or just create more work. 

Trust me, this journey isn’t as straightforward as the marketing blurbs make it seem.

I learned the hard way that what works for one creator can be a total nightmare for another. That slick tool my mate raved about? 

Turned out to be a complete mess in my workflow. But that’s the thing about AI writing – it’s deeply personal. 

Some tools just click, while others feel like wrestling with a stubborn piece of technology.

My biggest advice? Don’t just take my word for it. Most of these platforms offer free trials, so go wild and experiment. 

I wish someone had told me this earlier – start small, mess around, and find what feels right for you. Some days, an AI tool will feel like your best writing buddy. 

On other days, you’ll want to throw your laptop out the window.

Curious about something?
