Don't write a book nobody is searching for.
Galley pulls live Amazon page-one data on your topic and hands you a verdict before you write a word. Enter, caution, or avoid. Real thresholds, not vibes. The check is free and takes about a minute.
No card. No signup wall. One topic, one verdict, about a minute.
Built on the niche framework used by a community of 2,000+ publishers.
Three months is a long time to spend on a guess.
Here is how most first books die. Not in the writing. In the choosing. You pick a topic because you like it, or because a video said the niche is hot, and you spend weeks outlining and drafting and second-guessing. Then you publish, and page one never comes, because forty other books already own it, or because nobody was typing that search in the first place. The work was fine. The market was never there. And the worst part is that the data that would have told you was public the whole time, sitting on Amazon's page one, free to read for anyone who knew what to check.
The verdict comes first. Everything else waits.
Type your topic into Galley and it pulls the live page-one data a working publisher would spend an afternoon collecting by hand. Then it rules on it. Enter, caution, or avoid. The thresholds are fixed and public: at least three page-one books each selling under a 30,000 Best Sellers Rank, total search results under 3,000, and page-one competition weak enough, measured by review counts, that a brand new book can actually break in. Miss the bar and the verdict says so to your face.
Interactive sample. Three example topics, real threshold logic.
Avoid is the best word you can hear before writing.
An avoid verdict costs you one minute. The book it stops you from writing would have cost you three months. That is the entire trade. And avoid is not a dead end: one click generates ten tighter sub-niches built from the exact phrases real buyers type, re-runs the checks on each, and keeps going until the verdict turns. You do not abandon the idea. You aim it.
Film arriving shortlyThen it reads the one-star reviews so your book starts ahead.
Once a niche clears, Galley mines the negative reviews of the books already ranking, finds what readers actually complain about, and builds your outline to fix those exact complaints. Every chapter carries a job. Your book enters the market answering the objections the current bestsellers left open, which is the only honest edge a new title gets.
