Free AI SEO Tools
21 free tools to rank on Google and get cited by ChatGPT, Perplexity, and Claude. No signup, no credit card, no limits.
Featured Tools
Most PopularFreeAI Blog Generator
Generate a full SEO-optimized blog post from just your domain or topic. The tool analyzes your site's content, tone, and industry, then produces a publish-ready draft with proper H2/H3 structure, keyword placement, and a meta description. Built for founders who need content without hiring a writer.
llms.txt Generator
Create an llms.txt file from any website URL in seconds. The tool crawls up to 50 pages, maps your site structure, and outputs a file that follows the official llms.txt standard. Think of it as robots.txt for AI: it tells ChatGPT, Claude, and Perplexity what your site is about and which pages matter most.
Index Checker
Check whether your pages are actually indexed on Google. Submitting a sitemap tells Google your pages exist, but it does not guarantee indexing. Paste your URLs and find the invisible ones before they cost you weeks of lost traffic.
AI Search Optimization Tools
These three tools cover the new SEO stack: creating content, making it readable by AI models, and verifying Google actually indexed it.
SEO Title Generator
Generate page titles that fit Google's 60 character display limit and earn clicks. Each suggestion is built around your target keyword and search intent.
Meta Description Generator
Write meta descriptions that lift click-through rate. Keyword-aware suggestions within the 150 to 160 character sweet spot Google actually displays.
Headline Generator
Create headlines that stop the scroll. Power words, numbers, and curiosity hooks without crossing into clickbait.

Turn a keyword into a complete post structure with H2s, H3s, and talking points per section. Skip the blank page and start writing with a plan.

Condense long articles into key bullet points. Useful for research, content repurposing, and adding TL;DR sections that AI engines love to cite.

Why These Tools Exist
Most free SEO tools were built for a world where Google was the only channel that mattered. That world is gone. AI-powered search through ChatGPT, Perplexity, Claude, and Google AI Overviews now answers a growing share of the questions your customers ask, and those answers are pulled directly from website content.
Websites that optimize for both channels today capture traffic their competitors miss entirely. These tools help you do exactly that: create content that ranks on Google, make your site readable by AI models, and verify your pages are actually indexed and discoverable.
Every tool on this page is fully free. No usage caps, no login walls, no feature gating. We built them because we use them ourselves, and because the best way to show what LeafPad can do is to let you test the output quality first.
Frequently Asked Questions
Are these tools really free?
Yes. Every tool on this page is completely free with no usage limits, no signup requirement, and no credit card. The AI-powered tools run on our infrastructure at our cost. We offer them free because they demonstrate the quality of LeafPad's full automation platform.
Do I need to create an account?
No. Every tool works without an account. Enter your URL, topic, or text and get results instantly. An account is only needed if you want LeafPad to automate your full content pipeline.
What is an llms.txt file?
An llms.txt file is a markdown file placed at your domain root that tells AI models like ChatGPT, Claude, and Perplexity what your site is about and which pages matter most. It works like robots.txt, but instead of controlling crawler access, it guides how AI represents your content.
How is the Index Checker different from Google Search Console?
Search Console requires verified ownership and shows indexing data only for your own properties. The Index Checker works on any URL instantly, with no verification. It is built for quick checks on new posts, client sites, or competitor pages.
How are these tools different from ChatGPT or other AI writers?
Generic AI writers produce generic text. These tools are purpose-built for SEO: they respect character limits, target keyword placement, follow heading structures Google rewards, and format output for direct use. You get publish-ready results, not a draft that needs reworking.
Will Google penalize AI-generated content?
No. Google's guidelines explicitly state that how content is produced does not matter; what matters is whether it is helpful, original, and people-first. Low-effort content gets penalized whether a human or AI wrote it. Well-structured, accurate, useful content ranks regardless of origin.
Can I use the output for commercial purposes?
Yes. Everything you generate with these tools is yours to use however you want: on client sites, in commercial projects, in paid campaigns.
How do these tools relate to LeafPad's paid product?
These tools handle individual tasks. LeafPad automates the entire pipeline: keyword research, a 30-day content calendar, daily writing and publishing, internal linking, and AI citation tracking. The free tools let you test our output quality before automating the whole system.
