What is it?
What is an AI keyword tool?
An AI keyword tool uses large language models to expand a single seed keyword, topic, or product description into a structured list of ranking opportunities. Instead of scraping Google autocomplete like legacy tools, it generates long-tail variations, clusters them by search intent (informational, commercial, transactional, navigational), and surfaces phrasing your audience actually uses. Our free version adds an AI-search layer — it flags which keywords trigger Google AI Overviews and which ones LLMs like ChatGPT, Perplexity, and Gemini already answer, so you can prioritize terms that earn both classic rankings and AI citations.
How to use the AI keyword tool
Type any seed: a product name, a topic, a service, or a rough description of the content you plan to publish. The tool generates a full keyword set in seconds — primary terms, long-tail variants, question-based queries, and modifier-driven phrases like "best," "free," "alternatives," and "vs." Each suggestion is tagged by intent so you can separate top-of-funnel discovery keywords from bottom-funnel buying queries. Pair the output with our Keyword Density Checker to validate coverage on existing pages, or drop the list into the Content Outline Generator to turn priority terms into an AI-citable brief.

Find low-KD long-tails

FAQ
Is this AI keyword tool really free?
Yes. Every keyword generation is 100% free, unlimited, and requires no signup, credit card, or email. Run as many seeds, niches, and topics as you want — the only daily cap you'll hit is your own time.
How is an AI keyword tool different from Google Keyword Planner?
Google Keyword Planner shows paid-search volume for exact keywords you already think of. An AI keyword tool starts with a seed idea and invents the full query universe — long-tails, questions, modifiers, and intent variants — based on how people actually phrase searches, not just what Google has already logged.
Does this tool include search volume and keyword difficulty?
The free AI keyword tool focuses on idea generation and intent clustering, not live volume or KD. For SERP-level numbers, pair it with a traditional volume source (GSC, Google Ads Planner) or upgrade inside AIclicks to get prompt-level AI-search volume across ChatGPT, Perplexity, and Gemini.
Can I use this for YouTube, Amazon, or other platforms?
Yes. Include the platform name in your seed — "YouTube keywords for electric bike reviews," "Amazon keywords for silicone baking mat" — and the AI returns platform-tuned phrasing. For deeper YouTube-specific research, pair with the YouTube Keyword Generator inside AIclicks.
Does the tool show which keywords are answered by ChatGPT, Perplexity, or Gemini?
Yes — this is our key difference. Alongside classic SEO keyword ideas, we flag which queries already surface LLM answers. That tells you where AI is the new competitor and where classic SERP clicks still convert. For ongoing LLM citation tracking, pair this with our AI Citation Tracker.
