My AI SEO Tools Stack
You’ll notice that this list is slightly different than above.
That’s because I believe (when used correctly), the following tools are as good as any dedicated AI SEO tool.
Plus, these are some AI tools I use on daily basis for SEO.
Let’s dive in:
1. Rankability
Rankability is the only AI SEO tool that I use every day.
In fact, I’m writing this blog post right now inside of the Content Optimizer.
Did you know that ChatGPT and Google use NLP (Natural Language Processing) to understand content?
These robots don’t actually read. They instead extract “entities” (people, places, and things) to understand the page.
So that means when you use Rankability, you’ll using the same exact technology that these tech giants are using.
In short, look at the recommended keywords and try to cover as many of them as you can.
This ensure that you’re building a highly relevant asset that AI platforms can easily understand.
Rankability also has a new AI Search Analyzer tool coming out soon.
This new AI search tracking tool will allow you track your brand mentions across ChatGPT, Perplexity, and Gemini.
2. ChatGPT
ChatGPT is also one of my daily driver for SEO campaigns.
Here are 10 ways to use it like a pro:
3. Replit
This one might seem odd, but I use Replit every day for technical SEO, landing page development, and so much more.
Our Rankability blog is hosted on WordPress, but our primary site is 100% created and hosted through Replit.
The entire website was built with AI. Watch this to learn more.
Other Awesome AI SEO Tools Worth Trying
We’ve personally tested and approve of the following AI SEO tools:
Clearscope
Clearscope is a streamlined AI SEO tool designed to improve content creation and boost organic traffic. It analyzes the search engine results page for your target keyword and provides a clear Content Score based on keyword density, word count, and topical relevance.
Its keyword suggestions, readability tips, and competitor analysis help refine blog posts and webpages for better visibility.
The clean interface keeps writers focused, and integrations with Google Docs and WordPress make it easy to fit into any content workflow.
Though pricier than some tools, its accuracy and usability make it a favorite among professional SEO teams.
Surfer SEO
Surfer’s Content Editor analyzes top competitors and guides terms, structure, and target word count; it includes Auto-Optimize, Humanizer, a Plagiarism Checker, and a real-time Content Score.
Recent updates added brand voice controls, faster Surfer AI, and rank-drop detection. Integrations cover Google Docs/WordPress.
Frase
Frase combines research, briefs, an editor, and dual SEO + GEO scoring that shows how content aligns with Google and AI platforms (ChatGPT, Perplexity, Claude, Gemini).
It analyzes the top Google results, surfaces questions/topics, and gives real-time optimization suggestions.
Marketmuse
MarketMuse’s patented AI inventories your site, models topical authority, and outputs prioritized topic clusters, briefs, and plan docs.
Current pricing/plan components include tracked topics, monthly Content Briefs, and a Strategy Document (quantity varies by tier).
Peec AI
Peec AI is an AI search analytics tool (not a writing editor) that tracks brand visibility, mentions, and sentiment across LLMs/AI results to show how assistants are framing your brand.
It’s designed for monitoring and reporting AI presence rather than generating content.
Semrush AI Toolkit
Semrush’s AI components center on Copilot (an AI dashboard assistant that surfaces recommendations from your Semrush data) and SEO Writing Assistant (Docs/Word/WordPress add-ons for readability/SEO/originality/tone).
Some coverage refers to a broader “AI Toolkit,” but the official, concrete features are Copilot + SWA.
SE Ranking
SE Ranking’s Content Editor builds briefs, suggests related terms/headings, and scores content; it integrates directly with Google Docs and ties into the broader SE Ranking suite (rank tracking, audits, etc.).
Ahrefs
Ahrefs now offers Ahrefs AI, which layers AI on top of Ahrefs’ dataset to streamline keyword research, content creation, brand tracking, technical SEO, and localization.
Ahrefs continues to provide deep keyword, backlink, and site audit data while adding AI-assisted workflows and integrations.
Scalenut
Scalenut combines research, briefs, AI writing, and optimization.
Cruise Mode generates first drafts in a guided workflow and is now positioned to make content LLM-ready; Auto-Optimizer fills NLP gaps, refines tags/structure, and supports internal linking.
Writesonic
Writesonic pairs an AI Content Engine with AI visibility tracking across platforms like ChatGPT/Gemini/Perplexity.
Its AI Article Writer 6 offers a research mode that analyzes competing articles and includes competitor analysis and up-to-date info. (Position today: creation + AI-visibility, not just an “SEO checker.”)
AirOps
AirOps is a no-code workflow builder for content/SEO teams: create AI pipelines for research, drafting, refreshes, and reporting.
It integrates with SEO data sources (e.g., Semrush steps for backlinks and ranking keywords) and showcases SEO team use cases and results.
Profound
Profound focuses on AI search visibility (AEO).
It measures traffic influenced by AI results, tracks which pages get cited in AI answers, and publishes guidance on optimizing sites for AI agents and answer engines. It’s aimed at monitoring/optimizing brand presence in AI-generated responses.
Conclusion
If you only pick one AI SEO tool, choose Rankability. It unites research, briefs, content creation, on-page optimization, and monitoring in one workflow.
You get focused briefs, a clean editor with real-time coverage signals, and reporting that proves impact across Google and AI answer engines. Teams publish faster, fix gaps sooner, and protect budgets by avoiding a patchwork of tools.
Start with Rankability as your core, then add specialists only if needed. You will move faster, spend less, and rank higher with greater consistency.
