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 structured map of everything you could realistically write about within that subject. Instead of one idea, you get a spread, organised into broad pillar themes with specific subtopics branching off each one.
What Rext AI Provides
Rext AI topic generator takes one keyword you enter and expands it into a structured topic map, broad pillar themes with specific subtopics branching off each one, so you see the whole subject at once instead of a single idea
How it works
How to Use the Topic Generator
- 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
Add your niche if you have one
The optional niche field does more work than it looks like it should because the same seed keyword produces genuinely different, more usable results once you've told the tool who it's for.
- 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
Check each topic against your existing content
Before adding anything to your calendar, search your own site. A topic map built from a fresh keyword won't know what you've already published, so this step catches overlaps the tool can't.
- 5
Validate demand on your shortlist
Not every generated topic will have meaningful search volume. Run your favourites through proper keyword research before committing writing time, since a well-structured but low-demand topic still won't bring in traffic.
- 6
Build your calendar pillar by pillar, not randomly
Publishing topics from the same pillar close together, then internally linking them, builds topical relevance far faster than jumping between unrelated pillars every week.

Key Features and Capabilities
Search intent
Each topic has different intent, so you know whether it wants to be a guide, a comparison, or a product-focused page before you start writing.
Niche-aware expansion
The optional niche field meaningfully changes the spread of topics returned, not just the wording.
Scales from ten to thirty topics
Start small for a quick brainstorm or go large for a full quarter's planning session.
Frequently asked questions
Topic Generator starts from a single keyword and maps out the broader subject into pillars and subtopics, giving you a strategic view of a whole 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.
No, the niche field is optional, but adding it sharpens the spread considerably, so it's worth filling in when you have one.
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.
It's a signal for what kind of content the topic wants to be. Informational topics suit guides and explainers; commercial and transactional topics suit comparison or product-adjacent content. Getting this right early saves you from writing a guide for a topic that should have been a buyer's comparison page, or the reverse.
