This guide provides a direct comparison of two prominent platforms, Writesonic and SEO.ai, based on a detailed review of their features, SEO capabilities, and pricing to help you make an informed decision.

Understanding AI SEO writing tools

AI SEO writing tools are advanced platforms that go beyond simple text generation. They create content specifically designed to rank on search engines like Google. The focus is now expanding to include Generative Engine Optimization (GEO), which optimizes content for AI answer engines, such as ChatGPT, Perplexity, or the AI Overviews being rolled out by Google. Since traditional SEO principles are fundamental to GEO, these tools help cover both aspects of modern search visibility, as this graphic illustrates. That is what these tools are for.

While this is a deep dive into Writesonic vs SEO.ai, seeing them next to other tools provides a more complete picture. Different platforms solve different problems, so here’s a look at the top five I put to the test.

1. eesel AI blog writer

The eesel AI blog writer is designed to take a single keyword and transform it into a complete, SEO-optimized blog post that’s ready for publication.

The tool was developed to scale content production, helping one blog grow from 700 to over 750,000 daily impressions in three months after publishing over 1,000 articles.

Why we like it: eesel AI is designed to produce a complete article, not just text. Its research is context-aware, and it automatically adds AI-generated images, infographics, relevant YouTube videos, and quotes from Reddit to build credibility. It is also optimized for AI Answer Engines (AEO). This can save users time that would otherwise be spent finding and adding assets manually.

Limitations: The eesel AI blog writer is a specialized tool. It’s focused entirely on creating long-form blog content. If you need a tool that also writes short copy for social media or Google Ads, this may not be the right fit.

Pricing: It is free to try. The paid plan is $99 for 100 blog posts per month.

2. Writesonic

Writesonic is a comprehensive platform that combines content creation with a set of tools for both traditional SEO and emerging AI search.

Why we like it: Writesonic's notable feature is its focus on Generative Engine Optimization (GEO). It has built-in tools to track how often a brand appears in AI-generated answers from platforms like ChatGPT, Gemini, and Claude. It operates on the principle that strong SEO builds a foundation for good GEO and provides a single dashboard to manage both. It’s also versatile, handling everything from articles to ad copy, and even has AI agents for SEO tasks.

I've been using Writesonic and have seen good visibility improvement. Many of my clients mention they are getting leads who say they found them through AI search so I know whatever this tool suggests is working. i say Writesonic is more value for money.

Reddit

Limitations: For all its features, the content can sometimes sound generic and may require significant editing to fit a specific brand voice. Also, some of its features, like the AI Visibility Action Center, are only available in a custom Enterprise plan, which may be out of reach for most small businesses.

Pricing: Writesonic offers a limited free plan. The paid Lite plan is $39/month (if billed annually), but the GEO tools are part of the Professional plan, which is $199/month (billed annually).

3. SEO.ai

SEO.ai is focused on automation. It aims to put the entire content process on autopilot, from planning to publishing.

Why we like it: The "autopilot" feature is its main attraction. The tool can scan a website, find content gaps where competitors are outranking it, and then automatically create and publish articles to fill those gaps. Its support for over 50 languages is a significant advantage for businesses with a global reach. The automated internal linking feature also helps build topical authority with minimal manual effort.

Limitations: As a newer tool, it doesn't have the long track record of some competitors. The heavy reliance on automation means users need to invest time in the initial setup and monitor the output to ensure it remains on-brand.

Pricing: A 7-day trial is available. The basic toolset starts at $49/month, but the full autopilot plan for one site costs $149/month.

4. Frase

Frase is designed for content planners and researchers. It is a tool that helps users understand what it takes to rank for a keyword before writing begins. It focuses on creating data-driven content briefs to guide writers.

Why we like it: Frase excels at SERP analysis. It breaks down the top-ranking articles for a keyword and identifies commonalities, from headings and topics to frequently asked questions. It provides both SEO and GEO scores as you write, helping to cover all bases. Its outline builder is among the best for creating a solid, data-backed structure.

Limitations: Frase is more of a research assistant than a bulk content creator. For those who need to produce a large volume of articles quickly, its process might seem slow. While it offers "Rank-Ready Documents", they are priced on a pay-as-you-go model, which can become costly when scaling content.

Pricing: The Starter plan is $38/month (when billed annually) and includes one user and 15 content projects.

5. SEMrush

SEMrush is more than an AI writer; it's a complete digital marketing toolkit. It is an industry-standard platform that has incorporated AI features into its extensive list of tools.

Why we like it: SEMrush provides a vast amount of data for keyword research, competitor analysis, backlink audits, and nearly any other SEO task. Its SEO Writing Assistant is a useful feature that offers real-time feedback as you write and integrates directly with Google Docs or WordPress. With its Semrush One plan, it also includes an AI Visibility toolkit to track performance in AI search.

Limitations: SEMrush is a professional-grade tool with a corresponding price. It's a complex platform, and its primary focus is on analytics and research; content creation is just one component. If the only requirement is an AI writer, this platform may be more than what is needed and not the most budget-friendly option.

Pricing: The Semrush One Starter plan begins at $165.17/month (when billed annually).
