Describe your video topic, and this tool generates a primary keyword to build your title around, a set of tags for YouTube Studio, real search phrases viewers type in, and supporting keywords for your description — all in one pass.

Where each keyword type goes

  • Primary keyword: your video title and the opening line of your description
  • Tags: the tags field in YouTube Studio when you upload
  • Search queries: use these to sanity-check your title matches how people actually search
  • Description keywords: weave these naturally into your full video description
