How to use the board to pick AI tool niche ideas

01

Start with the niche score

A 0–100 percentile blend of search value (volume × CPC), paying sites, checkout traffic and new keywords in the last 7 days. High = big pond, fish in it, still growing.

02

Check payment evidence

Medium or strong checkout traffic, or several sites reporting revenue, means people really pay here. "Free pond" marks niches with big search and little money.

03

Open a niche, pick a keyword group

Each niche page lists top keyword groups with our verdict and reasoning. Pick a "keep" group that is not a red ocean for your first page.

FAQ: finding AI tool niche ideas

Where does the data come from?
Search volume, CPC and KD come from Similarweb keyword exports (global, last 28 days) — about 14,758 keywords that were each reviewed for "can an indie maker build a site for this". Payment evidence comes from TopCheckouts (checkout-page traffic, shown as tiers) and TrustMRR (founder-reported MRR, shown as site counts and a median band). The niche score is our own 0–100 blend of search value, paying sites, checkout traffic and 7-day new keywords.
How often is it updated?
Once a day, automatically, after our demand radar finishes its daily run. The date at the top of the board tells you which day you are looking at. A weekly report (in Chinese) comes out every Monday.
How accurate is it?
Volume and CPC are Similarweb estimates, so use them to compare niches and judge order of magnitude rather than as traffic forecasts. Payment evidence shows that someone is charging money in a niche; it is not revenue. Niches are rule-based, so a few keywords land in the wrong one.
Why are payment signals shown as tiers instead of exact revenue?
Exact MRR and checkout visits belong to TrustMRR and TopCheckouts. We publish the derived tier (none / weak / medium / strong, number of paying sites, median MRR band) and link each site back to its source page, where you can see the original figures.
How do I use this to pick what to build?
Start with the niche score, then look for medium or strong payment evidence, and skip niches marked "Free pond". Open a niche to see its top keyword groups with our verdict and reasoning, and pick a group marked "keep" that is not a red ocean for your first page.
What is a "Free pond"?
A niche whose search value ranks in the top 10 while founder-reported revenue sits below the median of all niches — PDF tools and vector conversion are typical. Lots of people search, few pay, so plan how you will make money before you build.
Do I need an account?
Without an account you can read the niche board, the weekly report, the method page, the first 10 keyword groups of each niche, and the first 20 new words from the latest batch. A free account shows the first 30 groups, every new word in that batch, and one watch. Pro shows every group, filters, CSV export (20 a day), 90 days of new-word history, and unlimited watches.
How much does it cost?
Check out with PayPal. You can pay by card, no PayPal account needed. Pro is $12 a month, or $96 a year (that is $8 a month, paid once a year as $96, 33% less than paying monthly). You can cancel any time and keep Pro until the period you already paid for ends. A refund stops Pro immediately. PayPal issues the receipt. Email support@waxuqiu.com.
How do I contact you?
Email support@waxuqiu.com. If a payment did not finish, include the PayPal email on the order.
