Which one is for you
Pick Keyword Insights if
- Fits if you have thousands of keywords and need to know which ones belong on one page
- Works for content teams that want research, briefs and drafts in the same place
Look elsewhere if
- Pricey if you mostly want AI articles, as Basic's credits cover about 8 and nothing else
- Tight if you work with others, as Basic has one seat and sharing starts at $99
- Not for you if you hate credits that expire, as unused ones reset every month and all go when you cancel
- Watch out: pay-as-you-go credits only work for clustering and expire 30 days after purchase
- Watch out: the 7-day trial costs $1 and needs a card
Pick WriterZen if
- Fits if you would rather pay once than keep a subscription
- Works for a small content team planning topic clusters from allintitle data
Look elsewhere if
- Skip it if you want the writing tools for $135, as they need the $270 package
- Tight if you add people, since extra seats are $9 each a month even on a lifetime deal
- Pricey if you burn through credits, as extra keyword credits start at $19 per 10,000 and NLP credits are extra
- Watch out: the FAQ calls the packages a limited deal that can only be upgraded during the event
- Watch out: it's web only with no API on record, and it's a large suite with a learning curve

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.
