Which one is for you

Pick KeywordTool.io if

  • Fits if you want long-tail ideas from YouTube, Amazon or TikTok and can do without the numbers
  • Works for pulling keyword data into Claude or ChatGPT through the MCP server on a paid plan

Look elsewhere if

  • Pricey if you only want search volumes, at $68 a month on yearly billing and $88 monthly
  • Skip it if you need a difficulty score to judge which keywords you can win
  • Not for you if you want to try the paid data first, as there's no trial, only a 30-day refund
  • Watch out: only Google and Bing volumes come from the ad planners; the rest are modeled estimates
  • Tight if you run lots of lookups, as Starter allows 50 requests a day across web, API and MCP

Pick Rakko Keyword if

  • Fits if you write for Japanese readers and want suggest data from Rakuten and Amazon
  • Works for a budget of a few hundred yen a month, at ¥660 for Entry on yearly billing

Look elsewhere if

  • Skip it if you can't read Japanese, as the site and support are in Japanese
  • Not for you if you want to try paid features first, as there's no trial and no refund mid-term
  • Tight if you pay monthly, since that costs twice the yearly rate, and plans can't be downgraded without cancelling
  • Watch out: lookups through AI tools burn credits 5 times faster on Light, and the API needs Standard
  • Tight if you stay free: 50 credits a week and no search volume at all

How we grade them

Value for money
DStarter is $68 a month on yearly billing, $88 monthly, which is in this category's dearest tenth. Every paid plan does include the API, an MCP server and volume for 50,000 keywords a day. There's no trial, only a 30-day money-back guarantee.
AEntry is ¥660 a month on yearly billing, tax included: a few dollars, and under 60% of this category's cheaper quarter. It's only 400 credits, though, the API waits on Standard at ¥2,475, and monthly billing costs double.
Free plan and trial
BThe free version needs no account and no card, and gives up to 750+ suggestions a search with no limit on record. One person could live on that for ideas. What you don't get is volume, CPC or competition: those are all paid.
CA free plan with 50 credits a week, reset every Monday, for suggestions, competitor keywords (50 results) and rank checks to position 30. No search volume at all, which is the number you came for.
Features
CIdeas from 17 platforms, plus volume, CPC, trend history and bulk lookups on paid plans. But there's no difficulty score or competitor lookup on record, and only Google and Bing volumes come from the ad planners.
CSuggestions from five search engines, volume and difficulty, competitor keywords, headings from the top 20 results, rank checks, AI drafts and MCP. It covers the job, but for Japan: the site, support and keyword data are all aimed there.
Ease of use
BNo rating on record, and nothing to set up: the free version runs without an account, so you type a word, pick a platform and read the list.
CNo rating on record. The tools are simple lookups, but the whole site is in Japanese, and each tool costs a different number of credits, so there's some working out to do.
Platforms and integrations
BWeb only, with no desktop or phone app. Every paid plan has a REST API and an MCP server for Claude, ChatGPT and Cursor, all drawing on the same daily request pool.
BWeb only, with MCP for Claude, ChatGPT, Gemini, n8n and Dify from Light, and the API from Standard. Results go to Google Sheets or Excel. No desktop or phone app.

How this page was made

  • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
  • The grades are our own, from each tool’s review or report card. The GPA is their average.
  • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
  • The differences and the answers to the questions are worked out from those listings.
