What a keyword gap
The searches a competitor already wins are proof of demand in your category. The gap is where to write next.
Their top 20, minus yours
We take every search the competitor ranks for in Google's top 20 in your market and keep only the ones where your site ranks nowhere in the top 100.
No brand noise
Searches with either brand name in them are left out, so the list shows topics you can compete for, not "their brand plus login".
The AI layer
Each row says whether Google shows an AI Overview for the search. Those are the ones where being cited matters as much as ranking.
Next step
Find gaps against every competitor in Rank PromptKeyword research in the app takes the competitors AI answers name and shows the searches each one holds that you do not.
Go from one snapshot to always-on AI visibility
The free tool is a fast, honest starting point. Rank Prompt turns it into a program that tracks, compares, and improves how AI answers talk about you.

Where does the data come from?
From a ranking database that tracks Google results for millions of searches, refreshed weekly. It is the same source Rank Prompt's keyword features use.
Why do I see only twenty keywords?
The page shows the biggest twenty to keep it free. The full list, up to 200 searches, comes by email after you confirm your address.
How do I pick which keywords to go after?
Start with searches close to what you sell, with difficulty you can match, and with an AI Overview you could be cited in. A page that answers the question directly can win both.
Can I compare with more than one competitor?
Here, one at a time. Rank Prompt compares you with every competitor your AI answers name and merges the gaps.
How many checks can I run?
A few a day, to keep it free. The same pair in the same market within a day returns the same result at no cost.
Close the gap, then track it
Find the searches your competitors win, write for them, and track the rankings and AI answers that follow.
