Free AI Keyword Research Tool
Free AI keyword research tool that pulls live Google and Bing suggestions, then scores intent, difficulty, CPC tier and opportunity for every keyword.
What is an AI keyword research tool?
An AI keyword research tool collects real search suggestions for a topic and then analyses them automatically, so you do not have to sort hundreds of phrases by hand. It tags search intent, estimates difficulty and CPC, scores each keyword’s opportunity and groups related terms into topic clusters you can plan content around.
Most “AI” keyword tools fall into one of two camps. Some send your seed to a large language model, which invents plausible-looking keywords that nobody may actually search. Others start from real query data and use automation to make sense of it. We built ours the second way, on purpose. Every keyword in the table above came from Google Autocomplete or Bing suggestions a few seconds ago, which means real people typed something close to it recently.
Let us be straight about the label. The “AI” here is automated, rule-based analysis: pattern matching for intent, a scoring model for difficulty and cost-per-click, and a frequency-based clustering step. It is not a paid AI model and it does not have access to private search volume data. That trade-off is what lets the tool stay free with no sign-up, and for early-stage keyword research it covers most of what you need.
What happens when you press Analyze
- Collect. The tool queries Google Autocomplete for your seed, question prefixes (how, what, why, can) and, in Deep mode, every letter from A to Z. Bing suggestions are added on top.
- Clean. Duplicates and off-topic phrases are removed, and each suggestion’s position is recorded. A phrase that appears first across several lists gets a stronger popularity signal.
- Score. Each keyword gets an intent tag, an estimated difficulty from 5 to 95, an estimated CPC tier and an opportunity score out of 100.
- Cluster. Keywords that share the same modifier (say “women”, “trail” or “nike”) are grouped so you can see the topics hiding inside one seed.
A quick worked example. Run “running shoes” in Quick mode for the United States and you will typically get 60 to 90 unique phrases. “running shoes for flat feet” usually lands with an estimated difficulty around 41 (five words, an audience qualifier, no money words) while “best running shoes” sits closer to 66 because “best” signals a crowded comparison SERP full of big publishers. That gap is exactly what you want to see before you commit a writer’s week to a topic.
Features that make this free keyword tool useful
Every phrase is pulled in real time from Google Autocomplete and Bing, not generated by a language model.
Informational, commercial, transactional, local and navigational labels help you match each keyword to the right page type.
A 5–95 heuristic based on word count, modifiers and commercial terms. Good for sorting, not a replacement for a backlink audit.
Low, Medium, High or Very high, inferred from buyer modifiers and expensive industries such as insurance, legal and SaaS.
Blends popularity, ease and commercial value into one number so the best first targets float to the top.
Group keywords by shared modifier, filter by intent or score, then copy or download as CSV or TXT.
How to use the AI keyword research tool
Enter a seed keyword
Type a broad topic of one to four words, like “crm software” or “keto breakfast”. Very long seeds return fewer suggestions.
Pick country, language and depth
Choose the market you are targeting. Quick mode makes 9 requests; Deep A–Z makes 30 and usually returns two to three times more keywords.
Press Analyze Keywords
Wait a few seconds while suggestions load. The table sorts by opportunity, highest first. Click any column header to re-sort.
Filter, cluster and export
Narrow by intent or minimum opportunity, switch to Topic clusters to plan pages, then download the CSV and verify volume in Google Keyword Planner.
How are difficulty, CPC and opportunity estimated?
Difficulty starts from word count, because shorter queries attract more competing pages, then adds points for comparison words, buyer words and expensive industries, and subtracts points for questions, local terms and specific qualifiers. CPC tier follows commercial signals. Opportunity blends popularity, ease and commercial value.
| Signal | What raises it | What lowers it | How to verify |
|---|---|---|---|
| Est. difficulty | 1–2 word head terms, “best”, “vs”, “review”, money niches (loans, lawyers, hosting) | Questions, 4+ words, “for”, “without”, local terms, a year | Look at the top 10 in Google Search: forums and thin pages are a good sign |
| Est. CPC tier | Buy, price, hire, near me, software, insurance | How, what, why, ideas, examples | Google Keyword Planner top-of-page bid range |
| Popularity signal | Appearing early and in several suggestion lists | Appearing once, near the bottom | Google Trends interest over time |
| Opportunity | High popularity + low difficulty + some commercial value | Hard head terms, or terms nobody seems to search | Your own Search Console impressions after publishing |
The formula is simple enough to sanity-check: opportunity = 45% popularity + 40% ease (100 minus difficulty) + up to 15 points for CPC tier. Take “running shoes for flat feet” with a popularity signal of 60, difficulty 41 and a Medium CPC tier: 27 + 23.6 + 5 rounds to 56. Not glamorous, but a solid page-one candidate for a site with modest authority.
Where heuristics fall short: they cannot see who already ranks. A four-word query can still be owned by Amazon and Reddit. Treat the scores as a first sort, then open the SERP link beside each keyword and look for yourself.
Which search intent should you target first?
Search intent decides the page type, and getting it wrong is the most common reason a well-written article never ranks. Here is how we use the intent column when building a content strategy for clients.
| Intent | Example | Best page type | Our take |
|---|---|---|---|
| Informational | how to clean running shoes | Guide or how-to post | Cheapest traffic and the base of topical authority. Start here on a new site. |
| Commercial | best running shoes for beginners | Comparison or roundup | Valuable but competitive. Publish once you have supporting guides. |
| Transactional | buy trail running shoes online | Product or category page | Highest CPC. Often better won with PPC keywords first. |
| Local | running shoe store near me | Location or Google Business Profile | Handle through local SEO, not blog posts. |
Questions deserve special attention in 2026. People Also Ask boxes, Google AI Overviews and AI Mode all lean on pages that answer a specific question cleanly in the first two sentences. If the tool shows a cluster of “how” and “what” phrases, that is often a single strong FAQ-style article waiting to be written.
Frequently asked questions
Is this AI keyword research tool really free?
Yes. There is no sign-up, no credit card and no daily credit counter. The only limit is a fair-use cap of about 60 data requests per minute per visitor, which is enough for six or seven Quick runs a minute.
Does it show exact search volume?
No, and any free tool that claims exact search volume without Google Ads data is guessing. We show a popularity signal from suggestion rank and frequency. For real numbers, paste the exported keywords into Google Keyword Planner or check Google Trends.
What does “AI” mean in this tool?
It means automated, rule-based analysis: intent detection by pattern matching, a difficulty and CPC scoring model, and frequency-based topic clustering. It is not a paid large language model, so it never invents keywords that nobody searches.
How accurate is the keyword difficulty estimate?
It is a heuristic built on word count, modifiers and commercial terms, so it is good for ranking a list against itself, not for absolute numbers. Always check the actual SERP before you commit to a target.
Can I research keywords for other countries and languages?
Yes. Choose from 12 countries and 8 languages. Suggestions come from that market, so “football boots” in the UK and “soccer cleats” in the US will each show their own local phrasing.
What should I do with the topic clusters?
Treat each cluster as one page or one small content hub. Pick the highest-opportunity keyword as the main target, use the others as subheadings or FAQs, and link the cluster pages together to build topical authority.
