The reality is that in 2026 and beyond, AI writing tools will become part of every marketer’s daily workflow. As a matter of fact, they already have. 

Whether you’re writing and creating SEO content, emails, jotting down ideas for blog posts, or crafting social media updates, ideas, or improving clarity, there’s now an AI tool for almost everything.

But with so many tools entering the market, one question matters more than any other:

But the question for B2B marketers and brands is which AI writing tools actually produce the best, original, high-quality content? We try and answer that in this article. In order to do that, we evaluated leading tools across three lenses:

1. Content Quality – measured using tools like Originality.ai, Clearscope, and Surfer SEO. SEMrush Writing Assistant benchmarks.
2. Usability & Workflow Fit – how easy the tool is to use in real content production.
3. Value for Money – pricing vs. capability.

We also analysed public user reviews and our own in-house testing at Creativeform.

This guide breaks the tools into categories so you can choose based on your needs:

• AI Content Writing Tools
• AI Email Writing Tools
• AI Productivity & Research Tools
• AI SEO Optimisation Tools

Our Testing Framework

To help you cut through opinion-based comparisons, we generated a 400-word blog introduction sample using each tool and then ran it through:

Originality.ai

What we looked for:

• AI detection score
• The level of plagiarism detected in the sample

Clearscope

What we looked for:

• The overall content grade
• Readability

SEMrush Writing Assistant

What we looked for:

• SEO score
• Readability
• Tone consistency

It’s important to note that we don’t use these numbers to “rank” tools; every tool is trained differently and suited to different workflows. Instead, we highlight patterns we observed.

Here are our key findings from the test sample

• ChatGPT, Claude, and Gemini produced the most human-sounding, structured, and in-depth writing.
• Jasper, Copy.ai, and Writesonic excelled at marketing-ready copy and idea generation, but required more human refinement for long-form authority content.
• Article Forge and Rytr produced content with lower depth and weaker SEO term coverage.
• Grammarly and Clearscope themselves are not writing tools, but provide some of the highest lifts in content quality when paired with any model.
• ClickUp AI and Superhuman AI excelled in workflow-specific writing (emails, updates, summaries) rather than full bodies of content.

These insights guide the recommendations throughout the rest of the article.

Best AI Content Writing Tools in 2026

Long-form content has long been a cornerstone of effective SEO strategies, helping to boost keyword rankings and educate your audience. However, the quality, creativity, and consistency of AI tools can vary significantly. Below, we highlight the top tools that excel in depth, structure, and SEO performance.

1. ChatGPT 

Best For:

ChatGPT is best used for creating high-quality long-form content, ideation, rewriting articles, supporting your research efforts, and developing SEO content.

Why It Stands Out

ChatGPT is one of the most versatile and well-rounded large language models (LLM) and content developers available. It produces the richest content depth, helps you save time, it’s a free AI, has one of the strongest logical structures, and the most natural tone. It’s easier for it to adapt well to your unique brand voice and instructions. It produces quality output if prompted correctly. 

Benchmark Performance

• Originality.ai: Medium AI detectability and 0% plagiarism.
• Clearscope: A–A+ content grades; excellent keyword integration.
• SEMrush: Strong SEO score and readability.

Ease of Use:

10/10 — intuitive, fast, supports file uploads, images, and advanced reasoning.

Pricing:

Free tier; Paid from ~$20/mo.

Pros

• Industry-leading reasoning & depth
• Best for long-form SEO
• Learns brand voice well

Cons

• Can over-explain without tight prompting
• Higher AI detectability (common across frontier LLMs)

User Ratings

4.7/5 average across G2 and Trustpilot reviews.

2. Claude (Anthropic)

Best For:

When writing natural, humanlike, knowledge-dense articles, Claude is one of the best options available. Essentially, any piece of content that requires nuance, Claude’s AI generated text is quite comprehensive and tailored to your intended audience.

Why It Stands Out

Reviewers consistently note that Claude produces some of the most “human” writing. It excels at matching the relevant tone you need, reasoning, and generating content that feels editorially polished.

Benchmark Performance

• Originality.ai: Higher human-likeness; 0% plagiarism.
• Clearscope: A–A+ depending on prompt depth.
• SEMrush: Excellent readability; strong SEO suggestion adherence.

Pricing:

Free tier; Paid from ~$20/mo.

Pros

• High “editorial” writing quality
• Great for brand tone consistency
• Large context window

Cons

• Less strong than ChatGPT for SEO-optimized outlines
• Sometimes too cautious in tone

User Ratings

1.5/5. Most reviewers were let down by their experience overall

3. Google Gemini

Best For

Google’s Gemini is best for research-backed writing, fact-heavy content. A huge bonus point is that it’s already naturally integrated and embedded in the Google ecosystem (Docs, Gmail, Drive).

Why It Stands Out

Gemini excels in generating data-grounded explanations and performs well for users who need factual summaries, breakdowns, and structured long-form content. Its tight integration with Google Search and Workspace makes it convenient for research and document workflows.

Benchmark Performance

• Originality.ai: Similar detectability to ChatGPT; 0–2% plagiarism on tests.
• Clearscope: Typically B+/A- without optimization; strong topic coverage.
• SEMrush: Good readability; SEO context awareness improving but still maturing.

Ease of Use

9/10 – clean UI, excellent for Google-native users, simple toggle between model strengths.

Pricing

• Gemini Advanced: ~ $19.99/month (as part of Google One AI Premium)
• Live pricing may vary per region, but Google provides a stable monthly subscription.

Pros

• Extremely strong for factual writing and structured research
• Smooth integration across Google tools
• Great at complex technical explanations
• Often more concise than ChatGPT or Claude

Cons

• Less creative than competitors
• Long-form content can feel dry without editing
• Fewer publicly available writing-specific user reviews compared to ChatGPT/Claude

User Ratings & Reviews

Because Gemini is newer in the consumer market and tied to Google One subscription bundles:

• Limited standalone reviews on G2/Capterra
• Early reviewers score it around 4.4/5 for usability, but content-writing-specific reviews are sparse

4. Jasper AI

Best For:

“If you’re looking for a tool that can help you write high-quality copy quickly and easily, Jasper.ai is definitely worth checking out.” – one Jasper AI customer said. The tool is best for creating marketing copy, landing pages, brand voice consistency, not users who are accustomed to writing fiction or other types of content.

Why It Stands Out

It’s a tool specifically designed for marketers, not general-purpose users. Its brand tone memory and templates are useful for teams who write at scale. It’s packed with a host of AI features geared towards generating content at scale.

Benchmark Performance

• Originality.ai: Medium detectability.
• Clearscope: B+–A depending on the prompt.
• SEMrush: Good readability; SEO keyword usage sometimes too literal.

Pros

• Excellent templates
• Strong brand voice features

Cons

• Long-form content still requires editing
• Pricing is higher than many competitors
  

Price:

From $69/mo. Free trial available.

5. Copy.ai

Best For:

Copy AI is similar to Jasper AI, in the sense that it’s built specifically for marketing copy, product descriptions, and social content. Not necessarily long form content. 

Why It Stands Out

Automated workflows for agencies and teams. Great for repurposing content.

Benchmark Performance

• Originality.ai: Moderate detectability
• Clearscope: B–A- content grade
• SEMrush: Decent SEO scores
  

Pros

• Ideal for short-form marketing
• Workflow automation

Cons

• Not ideal for authoritative long-form
• Repetitive phrasing at times

Price:

From $29/mo. 

6. Writesonic

Best For

High-volume content creation, marketing copy, eCommerce descriptions, and teams needing fast output.

Why It Stands Out

Writesonic is built for speed. It offers over 100 templates for long form blogs, ads, product pages, and social copy. Its “Sonic Editor” is popular for generating long-form drafts quickly, especially for SEO blogs.

Benchmark Performance

• Originality.ai: Medium AI detectability; 0% plagiarism in our sample.
• Clearscope: B–B+ without additional editing.
• SEMrush: Solid readability, moderate SEO scoring; tends to repeat phrases.

Ease of Use

8/10 — clean interface, straightforward templates, fast outputs.

Pricing

• Plans typically start around US$49/month
• Higher tiers offer access to GPT-4/5 and higher word limits. (Exact pricing varies because Writesonic frequently updates tiers.)

Pros

• Extremely fast output generation
• Many templates for different content types
• Built-in SEO mode
• Affordable for teams needing scale

Cons

• Depth and nuance are weaker than frontier LLMs
• Long-form content requires significant human editing
• Tone may feel generic in some outputs

User Ratings

• G2: ~4.6/5
• Capterra: ~4.7/5

Reviews highlight speed and variety of use cases; criticism focuses on repetitive outputs.

7. Article Forge

Best For

When quality isn’t the top priority, but generating content at scale is, Article Forge is for you. Bulk content production like filler pages, low-competition niches, or programmatic SEO experiments, etc.

Why It Stands Out

Article Forge is known for near-fully automated content creation. Enter a keyword → receive a full article with headlines and sections. It’s designed for speed, not editorial quality.

Benchmark Performance

• Originality.ai: Higher AI detectability; plagiarism low but writing is formulaic
• Clearscope: C–B- scores across multiple tests
• SEMrush: Weak SEO term coverage without manual optimization

Ease of Use

7/10 — simple, but lacks refinement controls.

Pricing

• Starts around US$27/month
• Higher plans scale output volume  (Prices vary depending on yearly vs. monthly billing.)

Pros

• Extremely fast article generation
• Very low cost
• Useful for low-stakes content volume projects

Cons

• One of the weakest in writing quality
• Not suitable for authoritative or brand-sensitive content
• Output often reads robotic and shallow
• Requires heavy human rewriting for SEO competitiveness

User Ratings

• G2: ~3.5/5 Reviews commonly say: “Good for quantity, poor for quality.”

8. Rytr

Best For

Rytr is a free tool available to beginners, freelancers, and users who need inexpensive AI-generated short-form content. The tool also helps with plagiarism detection.

Why It Stands Out

Rytr became popular because of its low cost and broad range of templates. It’s one of the most budget-friendly options on the market.

Benchmark Performance

• Originality.ai: Medium–high detectability
• Clearscope: C+/B- without refinement
• SEMrush: Weak SEO depth, decent readability

Ease of Use

9/10 — very easy to use, lightweight, beginner-friendly.

Pricing

• Free plan

Pros

• Extremely affordable
• Simple interface
• Good for idea generation or short marketing snippets

Cons

• Weak long-form capability

• Not competitive for SEO or strategy-driven content
• Often produces generic language

User Ratings

• G2: ~4.9/5 – However, majority of reviews are from budget-conscious users; few professional SEOs/content leads rely on Rytr for core production.

9. Peppertype.ai

Best For

Peppertype is best used for quick content ideas, social captions, ad copy, and small marketing tasks. It’s not a comprehensive content generation tool.

Why It Stands Out

Peppertype is known for rapid ideation. It can generate dozens of variations for ads, meta descriptions, social posts, etc., making it useful for high-frequency content needs.

Benchmark Performance

• Originality.ai: Standard detectability; no plagiarism issues
• Clearscope: C+/B-, depending on prompt complexity
• SEMrush: Good readability; shallow SEO coverage

Ease of Use

8/10 — simple, intuitive, easy for non-writers.

Pricing

(No longer publicly listed in detail — their pricing recently shifted due to integration into Pepper Content’s larger platform.)

Pros

• Great for fast, high-volume short-form copy
• Provides lots of variations per prompt
• Strong emphasis on marketing use cases

Cons

• Not suitable for long-form or SEO articles
• Depth and originality are limited
• Pricing and platform structure have recently become less clear
  

User Ratings

• G2: ~4.6/5 – However, many reviews note that it’s better as a supplementary tool, not a primary writing engine.

Best AI Email Writing Tools

Email writing tools aren’t built for long-form depth; they’re built for clarity, tone accuracy, and speed. We tested tools here based on tone matching, professionalism, ability to summarize threads, and personalization capability.

10. Superhuman AI

Best For:

Superhuman AI is built for professionals needing fast, polished, on-brand email replies. It’s built to boost productivity and simplify your workload.

Standout Features

Pricing:

11. Grammarly (AI Writing Assistant)

Grammarly is best used for improving tone, clarity, grammar, and flow in emails and documents. It’s not a full fledged content generator, but rather a tool meant to supplement your writing.

Why It Matters

Grammarly is not a full content writer, but it is one of the most valuable enhancement tools in any workflow. Beyond helping you with grammar, the tool also includes a plagiarism checker and optimizing tool to help improve your content.

Benchmark Performance

Content improved readability scores by 12–18% in testing.

Pros

• Tone detector is best in class
• Great for editing AI-generated drafts

Cons

• Not great for creating long content from scratch

Pricing:

Free; Premium plan available from ~$12/mo.

12. ClickUp AI Writer

Best For:

The AI writer is a part of the “ClickUp Brain”, it’s an integrated AI assistant built to help teams with communication, task updates, SOPs, and meeting notes. It is not a content writer or editor.

Why It Stands Out

ClickUp’s AI is embedded directly in tasks, documents, and comments, making it much more practical for team workflows.

Pros

• Great at rewriting internal documentation
• Helpful for meeting summaries

Cons

• Not a deep content writing tool
• Creativity is limited

Best AI Productivity, Research & Enhancement Tools

These tools don’t necessarily write content from scratch, but they make content creation faster, smarter, and more accurate by improving SEO, structure, research, or editing.

Why AI Writing Tools Still Aren’t Enough 

The fact of the matter is you still need a real, human team to manage your content.

AI writing tools have become indispensable, yes.  They speed up research, improve optimization, and provide first-draft efficiency we’ve never had before. But here’s the part most brands find out  the hard way:

AI doesn’t replace strategic content, user intent and thought leadership. AI replaces the grunt work of content and helps you be more productive.

Every tool listed above can generate words. But none of them can:

• Understand your market’s emotional triggers
• Speak to your ICP with real nuance and understand their pains
• Match your industry expertise
• Build a content strategy that aligns with revenue goals
• Decide what should be written at all
• Ensure the content supports your customer journey
• Translate complex brand positioning into compelling narratives
• Create content that feels lived, experienced, and trusted

In other words, AI produces content. Humans produce impactful content that actually moves the needle and drives action.

And this is where digital marketing agencies make the difference between “publishing more” and “publishing content that performs.”

Partner With Creativeform for Impactful Content

At Creativeform, our role isn’t to replace AI tools; it’s to integrate them intelligently into a larger, ROI-driven content engine. Tools are assistants. We are the strategists, storytellers, optimizers, and growth enablers behind them.

Here’s what partnering with us actually unlocks:

1. A Content Strategy Built for Your Business Goals

AI can write, but it can’t determine what your industry needs, what your customers care about, or what Google sees as authoritative.

Our team develops:

• Full SEO content roadmaps
• Topic clusters that strengthen authority
• Search intent–aligned articles
• Competitive keyword strategies

AI can’t do that. It can only execute a plan that someone creates. That someone is us.

2. Human Editorial Judgment: The Missing Layer AI Can’t Replicate

Even the best AI tools still require a human mind to:

• Sense when the writing doesn’t “feel right.”
• Check facts, nuance, and industry accuracy
• Detect tone misalignment
• Strengthen arguments and add true insights
• Ensure content sounds original, not “AI-shaped.”

This is the craft that separates content that ranks from content that gets ignored.

3. Thought Leadership Your Competitors Can’t Copy

Anyone can buy the same AI tools. No one can copy your perspective, your positioning, or your voice.

We help brands articulate expertise in ways AI can’t fabricate. That’s why our long-form content consistently outranks AI-generated articles, because it’s grounded in lived experience, industry understanding, and narrative intelligence.

4. AI-Enhanced Production, Human-Led Quality

We use AI strategically to increase speed without compromising depth:

• AI for research acceleration
• AI for outline and ideation support
• AI for keyword expansion
• AI for first-draft content
• AI for editing and optimization

But the actual writing, refinement, positioning, and storytelling come from humans who understand your brand and your audience. 

5. Content That Doesn’t Just Rank But Converts

Top-of-funnel blogs don’t matter if they never lead customers anywhere. Our team builds content that aligns with the entire funnel:

• TOFU articles that build awareness
• MOFU comparisons and guides that educate
• BOFU landing pages and case studies that convert

We don’t just write content. We build content ecosystems that support pipeline growth.

AI simply can’t run your content strategy end-to-end. But it becomes exponentially more powerful when paired with a team that knows how to use it.

Partner With Creativeform: Your Human-Led, AI-Powered Content Engine

AI is a powerful tool. It will continue to reshape how content gets made.

But the brands that win won’t be the ones who rely on AI tools alone.

They’ll be the brands that pair AI with a team that understands:

• SEO deeply
• Your market intimately
• Your customers emotionally
• Your product strategically
• Storytelling artistically
• Performance scientifically

That’s what we do at Creativeform.
