The 5 best AI blog outline generator tools in 2026

You know the feeling. You've got a great topic, but you're just staring at a blank page. That blinking cursor seems to be judging your every move. How do you get from a single idea to a well-structured blog post that people will actually read? It's the classic writer's block, and it happens to everyone.

This is where an AI blog outline generator can really help. These tools provide a solid framework to get you started, taking the guesswork out of structuring your content. A good outline isn't just for readability; it's also a big deal for ranking on Google (SEO) and getting picked up by AI answer engines like Google AI Overview or Perplexity (AEO).

Here at eesel, we're all about scaling content, and we've learned that a solid structure is half the battle. We use our own eesel AI blog writer for this. It does more than just outline; it generates complete, ready-to-publish posts. It's been a huge help for us to move quickly, and it’s the first tool we'll look at.

What is an AI blog outline generator?

An AI blog outline generator is a smart assistant that maps out your article for you. You feed it a topic, a title, or a keyword, and it uses AI to generate a logical structure.

The whole point is to save you time, get you past that writer's block, and ensure you cover all your bases without going off on a tangent. Most of these tools analyze top-ranking articles for your chosen topic. They figure out what's already successful and then create a detailed structure with headings, an intro, a conclusion, and often a list of FAQs. It's like having a research assistant do the initial grunt work for you.

How we chose the best tools

To make this list actually useful for 2026, we set some ground rules and tested these tools based on what writers and marketers really need.

Here’s what we looked for:

• Quality of the output: Is the outline actually good? We wanted something detailed and logical, not generic AI fluff that you'd have to rewrite from scratch.
• SEO & AEO smarts: Does the tool think about search engines? We checked for features that incorporate keywords, suggest search-friendly headings, and consider what both human readers and AI answer engines are looking for.
• Ease of use: How fast can you get a usable outline? A good tool should be straightforward, not something that requires a dozen tutorials to get started.
• Customization options: Can you actually steer the AI? We preferred tools that let you add your own context, keywords, or a specific tone of voice to guide the output.
• Overall value: Is it worth the money? We looked for tools with a good free plan or a fair trial, with pricing that makes sense for the features offered.

The 5 best AI blog outline generator tools

Let's get into the details. Here’s our full review of each tool, covering what makes them stand out and where they might fall short.

1. eesel AI blog writer

First up is our own tool, the eesel AI blog writer. While it functions as an outliner, it is a more comprehensive AI content platform that manages the entire process. You give it a keyword, and it returns a complete, SEO-optimized, and media-rich blog post. The outline is just the first step in its automated workflow. After that, it does deep research, writes the content, creates assets like images and charts, and even finds relevant Reddit quotes and YouTube videos to add some social proof.

Pros: A key feature is its ability to generate a complete, publish-ready draft, not just an outline. It automatically learns your brand context from your website to weave in product mentions and internal links naturally. It's also optimized for AEO (Answer Engine Optimization). We created it to solve our own content scaling problem, and it's the exact tool we used to grow our blog from 700 to 750,000 impressions a day in 3 months.

Cons: For users who only require a simple, text-only outline and prefer to handle all research, writing, and asset creation manually, the platform's full suite of features might offer more than needed. It’s designed for users looking to streamline the content creation process from idea to publication.

Pricing:

• You can try it completely free to generate your first blog and see the quality for yourself.
• Paid: It’s credit-based, with a package of 50 blog posts for $99.

2. HubSpot's AI blog outline generator

As a well-known name in marketing, HubSpot offers an AI Blog Outline Generator. It’s a good choice for marketers, especially if you’re already using their AI-powered customer platform. You sign up for a HubSpot account, enter a topic, and it generates a few titles and outlines. Its main strength is how well it fits into the rest of HubSpot's ecosystem.

Pros: For existing HubSpot users, the experience is seamless. You can go from outline to draft right inside the platform you already use. For customers on higher-tier plans, it also provides some useful SEO data like monthly search volume (MSV) and keyword difficulty.

Cons: The main downside is that you have to sign up for a HubSpot account just to use it, which may not be ideal for those who don't need the full suite of HubSpot services. Access to detailed SEO data requires their Pro or Enterprise subscriptions.

Pricing:

• It's free to generate outlines.
• Advanced features are tied to paid plans like Content Hub Professional, which starts at $500/month.

3. Writesonic AI outline generator

Writesonic has repositioned itself as an AI Search Visibility Platform. They’re looking past traditional SEO and focusing on what they call Generative Engine Optimization (GEO), which is about getting your content cited by AI search platforms like ChatGPT and Perplexity. Their outliner is part of their "Content Engine," made to create content that ranks on Google and gets noticed by AI. It includes competitor analysis, web research, and automated internal linking.

Pros: Writesonic's unique angle is its focus on tracking your brand's visibility in AI search results. This platform is well-suited for SEO specialists interested in analyzing their brand's visibility in AI search results. It goes beyond just creating content.

Cons: Because the platform is so focused on AI search analytics and GEO, its comprehensive features may be more than what's needed for users seeking a simple outline tool. The full benefits are available in their Professional plans and higher.

Pricing:

• There’s a free trial that gives you 10,000 premium words to test it out.
• Paid plans start at $39 per month if you pay annually.

4. Copy.ai's AI blog outline generator

Copy.ai markets itself as the first AI-native Go-To-Market (GTM) Platform. It’s built to bring sales and marketing teams together with AI tools for prospecting, lead processing, and account-based marketing. The outline generator is just one feature in this larger platform, designed to quickly turn a topic into a basic structure to get things started.

Pros: The tool is fast and easy to use. If you just need to brainstorm some ideas or get a starting point without any fuss, it works well. It’s also part of a much larger platform that can automate complex workflows for sales and marketing.

Cons: The outlines it produces are generally basic and may not have the same level of SEO detail as more specialized content tools. The platform's real strength lies in its workflow automation, which requires a paid subscription to use effectively.

Pricing:

• The free plan offers 2,000 words per month.
• Paid plans unlock more credits and features.

5. Grammarly's AI outline generator

Everyone knows Grammarly for fixing spelling and grammar, and they’ve used that trusted brand name to offer a free AI Outline Generator. It’s simple, clean, and made for just about everyone, from students writing essays to professionals drafting reports. It's a reliable tool for creating a basic structure without signing up for a complex platform.

Pros: It’s totally free, easy to use, and has no hidden fees or confusing settings. The outlines are clean and logical, making it a dependable choice for general outlining tasks.

Cons: While its simplicity is a strength, it also means it lacks the specific SEO features you'll find in other tools, like keyword integration or competitive analysis. It’s more of a general writing assistant than a dedicated tool for creating content designed to rank in search engines.

Pricing:

• It's completely free to use.

Tips for getting the most from your AI outline generator

No matter which tool you pick, a little bit of strategy can make a big difference. Here are a few tips to get better results:

• Be specific with your input. Don't just give it a vague topic like "marketing." Try something more detailed, like "A beginner's guide to content marketing for small e-commerce businesses." The more context you give the AI, the better the outline will be.
• Add your keywords. If the tool lets you, include your primary and secondary keywords. This helps the AI build an SEO-friendly structure from the get-go.
• Refine and iterate. The first outline isn't always perfect. Don't hesitate to run the generator again with a slightly different prompt or manually adjust the output to better fit your unique angle.
• Use it as a starting point. An AI-generated outline is a great framework, but it's not the final piece. Your job is to bring it to life with your own stories, data, and insights. That's what makes content truly great.

For a practical demonstration of how to apply these tips and quickly create a solid outline, check out this video. It walks through the process of taking a simple idea and turning it into a structured plan in just a few minutes.

Moving from an outline to a finished post

AI blog outline generators are useful tools. They save time, help you beat writer's block, and give your content a solid foundation. They offer a significant improvement over starting with a blank page.

I'm finding AI to be a great tool - but not so great of a writer, especially for my blog posts. It generates ideas, builds outlines, and things like that - but it's still not quite trustworthy and does stupid things like making up links when it needs external links - it thinks something 'should' be there.. so it creates 'it.' Lol.

But at the end of the day, an outline is just the first step. The real work comes next: the research, the writing, finding images, and making sure it all connects with your audience.

For those looking to automate the entire process from keyword to a complete, publish-ready article, the eesel AI blog writer is an alternative to consider. It generates a complete post, including research, text, and assets. It is available to try for free.
