Keyword Tool turns a seed term into long-tail keyword suggestions drawn from autocomplete. It supports keyword and competitor research across 16 platforms, including Google, YouTube, Bing, Amazon, TikTok, Reddit, Pinterest, and Google Trends. The free tool needs no account and can generate 750+ Google autocomplete keywords. Paid plans add search volume, cost per click, competition scores, device breakdown, and historical trends; they also allow search-volume enrichment for up to 1,000 keywords per request. Access includes web, API, and MCP, with Claude, Cursor, and ChatGPT named as compatible assistants. Google coverage spans 190+ countries, 68,000+ locations, and 50+ languages. The site says Google and Bing metrics come from planner ecosystems, while volumes for other platforms are modeled estimates based on clickstream signals. Web, API, and MCP share a daily request pool, and available MCP tools can vary by endpoint, plan, and rollout status. Paid plans start at 68.00 USD per month; there is no free trial, and the pricing FAQ lists a 30-day money-back guarantee.
