Keyword Tool: cost, fit and limits
Keyword Tool is a keyword suggestion service at keywordtool.io that generates long-tail ideas from the autocomplete of 17 platforms, including Google, YouTube, Bing and Amazon, with a free version and a paid Pro tier that adds volume, CPC, competition and trend data.
What to know first
Keyword Tool has a free version that works without an account and a paid Pro tier. The visible pages give no per-plan prices: only structured data shows an offer range of USD 68 to USD 788 across 8 offers for Pro, with no billing basis. Pro adds search volume, CPC, competition, trend data, bulk upload and export, and includes API and MCP server access. The free version may show volume for only some keywords.

What Keyword Tool does
- Autocomplete across 17 platforms
- Suggestions come from search-engine and marketplace autocomplete, which tends to return phrases real users type. The list includes Google, YouTube, Bing, Amazon, Etsy and Pinterest.
- Volume from advertising platforms
- The page states that Google and Bing search volume is sourced from their advertising platforms. That is why volume needs Pro and why the free version shows it only for some keywords.
- Bulk upload and export
- Pro accepts bulk uploads of keywords and exports results to CSV or Excel, useful when a list from a client needs metrics attached in one pass.
- API and MCP server
- Every Pro subscription includes API and MCP access, and the pages name Claude, ChatGPT, Perplexity and Copilot as assistants it connects to for keyword data.
- Trend and competition data
- Pro shows trend data and competition alongside volume and CPC, helping separate seasonal terms from steady ones. The page does not describe a difficulty score.
How Keyword Tool handles your data
The privacy policy for keywordtool.io names Key Tools Limited in Hong Kong or Essential Apps LLC in the United Arab Emirates as the operating entity, so the pages we read do not settle a single headquarters country. We read only the opening section of the policy. It was not checked for retention, hosting region, model training or certifications, and none are claimed on the pages. Because Pro includes an API and MCP server, a team sending keyword lists through an assistant should ask the vendor how queries are logged and retained.
Where Keyword Tool falls short in practice
- No visible plan prices. Only a USD 68 to USD 788 structured-data range across 8 offers shows, with no plan names or billing basis. A buyer must open checkout to learn the real monthly cost.
- Free version is partial. Volume may appear for only some keywords on the free version, so it works for brainstorming but not for judging whether a term is worth targeting.
- No trial stated. Pro is the only paid tier named and no trial is mentioned on the pages opened. A cautious buyer cannot test paid features before paying.

Keyword Tool: common questions
How many platforms does Keyword Tool cover?
Keyword Tool generates suggestions from the autocomplete of 17 platforms, including Google, YouTube, Bing, Amazon, Etsy and Pinterest. The page lists these as the data sources for long-tail ideas. Marketplace sellers benefit most, since phrases typed into Amazon or Etsy differ from those typed into Google.
Is Keyword Tool free?
A free version works without creating an account, but it may show search volume for only some keywords. Pro adds volume, CPC, competition and trend data, bulk upload, export and API access. The pages opened mention no trial for Pro, so the free version is the only way to test.
How much does Keyword Tool Pro cost?
The visible text shows no per-plan prices. Structured data on the page lists an offer range of USD 68 to USD 788 across 8 offers for Keyword Tool Pro, without plan names, intervals or billing basis. Check the pricing page directly and confirm whether each figure is monthly, annual or per seat.
Can Keyword Tool connect to ChatGPT or Claude?
Yes. Every Pro subscription includes access to an API and an MCP server, and the page says the tool connects to AI assistants such as Claude and ChatGPT. Perplexity and Copilot are also named. Rate limits and credit rules for API calls are not stated on the pages we opened.
Who owns Keyword Tool?
The privacy policy for keywordtool.io names either Key Tools Limited in Hong Kong or Essential Apps LLC in the United Arab Emirates. The pages we read do not say which entity serves which customers, so no single headquarters country is stated here. Read the policy and terms before you sign up.
