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 Rapidtags if
- Fits if you want tags and a few keyword checks for each upload for $6 a month
- Works for small channels starting out with YouTube keyword research
Look elsewhere if
- Tight if you're staying free: 3 keyword searches and 3 rank checks a day, with ads
- Tight if you research a lot, since even Creator stops at 50 searches and 25 rank checks a day
- Not for you if you want to try before paying, as there's no trial and subscriptions aren't refunded
- Skip it if you want the full outlier and pattern analysis on Starter, as that's Creator only
- Too light for anyone wanting tools inside YouTube itself, as there's no extension or 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.
