The basics

What is a topic generator?

Why a topic generator matters

The distinction between a keyword and a topic is worth being precise about, because it's where a lot of content planning goes wrong. "Meal prep" is a keyword. It's not a topic you can write 1,500 words on without padding, because it's too broad to say anything specific. "Meal prep for a family of four on a $75 weekly grocery budget" is a topic. It has a defined audience, a defined constraint, and a defined scope.

What a topic generator does

A topic generator takes one keyword and expands it into a list of titles you could realistically write within that subject. Instead of one idea, you get a spread to choose from.

What Rext AI provides

Rext AI topic generator takes one keyword you enter and gives you up to 20 blog post titles around it, each within the word range you set, so you see many angles at once instead of a single idea

How it works

How to use the topic generator

Use the tool
  1. 1

    Start with a keyword you already know matters

    This works best with a keyword you've validated some other way, through your own audience research, existing traffic, or basic keyword research, rather than a guess. The tool expands what you give it; it doesn't tell you whether the seed keyword itself has demand.

  2. 2

    Add your audience to the keyword

    Put the audience in the keyword itself, such as "home office setup for remote developers", because the same seed keyword produces genuinely different, more usable results once you've told the tool who it's for.

  3. 3

    Then select word length and number of titles

    Choose the word length (minimum and maximum) and number of titles from the list below

  4. 4

    Check each topic against your existing content

    Before adding anything to your calendar, search your own site. A list built from a fresh keyword won't know what you've already published, so this step catches overlaps the tool can't.

  5. 5

    Validate demand on your shortlist

    Not every generated topic will have meaningful search volume. Run your favorites through proper keyword research before committing writing time, since a well-structured but low-demand topic still won't bring in traffic.

  6. 6

    Build your calendar in related groups, not randomly

    Publishing related topics close together, then internally linking them, builds topical relevance faster than jumping between unrelated subjects every week.

Frequently asked questions

How is this different from the content idea generator?

Topic Generator starts from a single keyword and returns a list of blog post titles around it, giving you a quick view of a content area. Content Idea Generator takes one specific topic you already have and turns it into format-ready ideas for a particular content type, like social posts or video scripts. Use Topic Generator to find the subject, and use Content Idea Generator once you know the subject and need format-specific angles.

Do I need a niche for this to work?

 No, but adding your audience to the keyword sharpens the spread considerably, so it's worth doing when you have one.

Will every topic have search demand?

Not necessarily, because this tool maps out what's conceptually related to your keyword. It doesn't check search volume, so validate your shortlist with dedicated keyword research before committing to a full calendar.

Start with one keyword.

Run it on your own site. Read the sources. Decide with the article in front of you, not a promise.
