Waitlist open
A Chrome extension for people who publish low-content and illustrated books — coloring books, journals, puzzle books. Open any Amazon search, get demand, competition and price depth for that niche in a side panel. No page reload. No login wall before you've seen anything.
These are public reviews of the most-installed KDP research extensions, left by publishers this year.
“When I click search it reloads the amazon page so I can't see results or save them.”
Chrome Web Store review
“Loading forever, no results showing up. I could wait until I die of old age.”
Chrome Web Store review
“Tried a couple keywords with the free version and after 3–4 checks it just said ‘no trial left’.”

“I spent 4 hours trying to research categories and got nowhere. I'm switching.”

Four promises, each one aimed at a specific complaint above. If we miss one, the product has failed at its job.
Enough to research a whole niche before you decide whether the paid tier is worth anything to you. The count lives in your own browser — we are not going to make you sign up so we can police it.
Our share of the work stays under two seconds. Amazon's share we don't control — when it drags, the panel says so and shows what it already has, instead of spinning.
Results open in a side panel. Your search, your scroll position and your open listings survive.
Amazon reshuffles its pages regularly and every tool in this category breaks when it does. Ours will too. The clock starts when a paying user reports that a search which worked yesterday returns nothing today; if the panel is still dead 48 hours later, that month costs nothing.
Example layout — figures are illustrative, not live data. For the real thing, see a finished niche report.

Not final, and nothing is being charged today. It is here so you can tell us if it is wrong.
25 lookups a day. No card, no account, no blurred numbers.
Unlimited lookups, saved niches, CSV export. Cancel from the panel in one click.
We can do the same work by hand today, for the niche you are actually considering. Four finished ones are already up: read the niche reports.
Back within 24 hours. One page: how many books already sit in that niche, where the top listings rank, what they charge, how many reviews they carry, how old they are — and a straight answer on whether there is room for another one.
You read the report first. If it didn't save you an afternoon, you owe nothing and we part friends. Ask for a report in the form below and we reply with both the report and a way to pay.
Waiting for the extension, or want a niche checked this week — same form either way. What you write here decides what gets built first.
