Keyword Tool is a keyword research tool that collects the autocomplete suggestions people see when they type into a search box. The free version gives long-tail keyword ideas from Google and 16 other platforms without an account. The paid plans add search volume, cost per click and trend data.
What is Keyword Tool?
Keyword Tool, at keywordtool.io, positions itself as an alternative to Google Keyword Planner. You type a seed word, pick a platform and a country, and it returns a list of longer phrases that real users search for. Because autocomplete reflects what people actually type, it is a quick way to find long-tail keywords and questions to answer in content.
Who is Keyword Tool for?
It suits content marketers, SEO specialists and video or e-commerce teams that need ideas for more than Google. A YouTube creator can pull suggestions from YouTube search, an Amazon seller from Amazon, and a social team from TikTok or Instagram. Teams that need backlink data, rank tracking or site audits will need a full SEO suite as well.
Key features
Suggestions from 17 platforms
Keyword Tool supports Google, YouTube, Bing, Microsoft Copilot, Perplexity, Amazon, eBay, the App Store, Play Store, Instagram, X, Reddit, Pinterest, Etsy, TikTok, Naver and Google Trends. The same seed word gives different results on each, which shows how intent changes by platform.
Search volume, cost per click and trends
Paid plans show monthly search volume, cost per click, a competition score and a device breakdown for each keyword. Trend history covers 12 months on Starter, 24 months on Growth and up to 48 months on Scale and Agency, so you can spot seasonal demand.
Location targeting
For Google, the vendor lists more than 190 countries, 68,000 locations and 50 languages. That helps when you write for one market or run local campaigns.
API and MCP
All paid plans include the web app, an API and an MCP server. The MCP server lets AI assistants such as Claude or ChatGPT query keyword data directly. All three draw on one daily request limit.

What do users say about Keyword Tool?
On Capterra, reviewers most often praise how easy Keyword Tool is to use and the number of long-tail ideas it finds across platforms. Export options and API access also get positive mentions.
The most common complaint is the price of the paid plans, which you need for search volume. Some reviewers also miss an SEO keyword difficulty score, which would show how hard a keyword is to rank for.
When should you choose an alternative?
- You want an all-in-one SEO suite. Semrush or Ahrefs add keyword difficulty, backlinks, rank tracking and audits.
- You want volume data inside Google. Keywords Everywhere shows metrics in your browser as you search.
- You need something cheaper. Ubersuggest or our list of free SEO tools may be enough.
