Why it exists
Publishing blind is the expensive part
Most books that fail were decided before a word was written — the wrong niche, a title nobody searches, a category already owned by three entrenched sellers. The information needed to avoid that is public. It is just tedious to gather.
Start with a topic
Enter a seed keyword or a title you are considering. No setup, no spreadsheets, no browser extension.
See the market
We pull what Amazon shoppers actually search, then measure each phrase against the Books category — competing titles, prices, how entrenched their reviews are.
Decide with numbers
A competition score per keyword, rank and review data per book, and a tracker that watches a title over time.
What it looks like
Numbers on the niche, not adjectives
Every search returns the averages for the whole result set — rank, sales, rating, review count — and then the individual books behind them, with price and royalty for each.
What you get
Four tools, and nothing you will never open
Every plan includes all of them. The difference between plans is how many searches you get, not which features are unlocked.
